The Ultimate Reusable Functions + +## Introduction + +In the context of functional programming and computer science, a **combinator** is a higher-order function that uses only function application and other combinators to define a result. Crucially, a combinator contains **no free variables**. This means it is a completely self-contained function that only refers to its own arguments. + +Combinators are fundamental concepts from **combinatory logic** and **lambda calculus**. While they have deep theoretical importance, their practical application in software development is to create highly reusable, abstract, and composable code, often leading to a **point-free** or **tacit** programming style. They are the essential glue for building complex logic by piecing together simpler functions. + +## Core Concepts + +### No Free Variables + +The defining characteristic of a combinator is that it has no **free variables**. A free variable is a variable referenced in a function that is not one of its formal arguments or defined within the function's local scope. This self-contained nature makes combinators perfectly portable and predictable. + +```javascript +const y = 10; + +// This function is NOT a combinator because it uses a free variable `y`. +// Its behavior depends on an external context. +const addY = (x) => x + y; + +// This function IS a combinator. It has no free variables. +// Its behavior only depends on its arguments. +const add = (x) => (z) => x + z; +``` + +### Function Composition and Transformation + +Combinators are designed to manipulate and combine other functions. They are the building blocks for creating new functions from existing ones without needing to specify the data that the functions will eventually operate on. The entire logic is expressed as a transformation of functions themselves. + +## Key Principles + + - **Point-Free Style (Tacit Programming)**: This is the primary programming style associated with combinators. You define functions as a pipeline or composition of other functions without explicitly mentioning the arguments (the "points"). This can lead to more abstract and declarative code. + + ```javascript + // Not point-free: the argument `users` is explicitly mentioned. + const getActiveUserNames = (users) => users.filter(user => user.active).map(user => user.name); + + // Point-free style: built by composing functions. + // `compose`, `filter`, `map`, and `prop` are all combinators or higher-order functions. + const getActiveUserNamesPointFree = compose(map(prop('name')), filter(propEq('active', true))); + ``` + + - **Abstraction**: Combinators abstract common patterns of execution and control flow. For example, the act of applying one function's result to another is abstracted away by the `compose` combinator. + +## Implementation/Usage + +Many famous combinators have single-letter names from combinatory logic. Understanding them helps in recognizing fundamental patterns. + +### Basic Example + +The simplest combinators are the **I-combinator (Identity)** and the **K-combinator (Constant)**. + +```javascript +/** + * I-combinator (Identity) + * Takes a value and returns it. + * I x = x + */ +const I = (x) => x; + +/** + * K-combinator (Constant or Kestrel) + * Takes two arguments and returns the first. Creates constant functions. + * K x y = x + */ +const K = (x) => (y) => x; + +// Usage: +const value = I("hello"); // "hello" +const always42 = K(42); +const result = always42("some other value"); // 42 +``` + +### Advanced Example + +More complex combinators handle function composition, like the **B-combinator (Bluebird)**. + +```javascript +/** + * B-combinator (Bluebird / Function Composition) + * Composes two functions. + * B f g x = f (g x) + */ +const B = (f) => (g) => (x) => f(g(x)); + +// In practice, this is often implemented as `compose`. +const compose = (f, g) => (x) => f(g(x)); + +// Usage: +const double = (n) => n * 2; +const increment = (n) => n + 1; + +// Create a new function that increments then doubles. +const incrementThenDouble = compose(double, increment); + +incrementThenDouble(5); // Returns 12, because (5 + 1) * 2 +``` + +Another useful combinator is the **T-combinator (Thrush)**, which applies a value to a function. + +```javascript +/** + * T-combinator (Thrush) + * Takes a value and a function, and applies the function to the value. + * T x f = f x + */ +const T = (x) => (f) => f(x); + +// This is the basis for the `pipe` or "thread-first" operator. +T(5, increment); // 6 +``` + +## Common Patterns + +### Pattern 1: Function Composition (`compose` / `pipe`) + +This is the most common and practical application of combinators. `compose` (based on the B-combinator) applies functions from right to left, while `pipe` applies them from left to right. They are used to build data-processing pipelines in a point-free style. + +```javascript +// Ramda-style compose, handles multiple functions +const compose = (...fns) => (initialVal) => fns.reduceRight((val, fn) => fn(val), initialVal); +const pipe = (...fns) => (initialVal) => fns.reduce((val, fn) => fn(val), initialVal); +``` + +### Pattern 2: Parser Combinators + +A parser combinator is a higher-order function that takes several parsers as input and returns a new parser as its output. This is an advanced technique for building complex parsers by combining simple, specialized parsers for different parts of a grammar. It's a powerful real-world application of combinator logic. + +## Best Practices + + - **Prioritize Readability**: While point-free style can be elegant, it can also become cryptic. If a composition is too long or complex, break it down and give intermediate functions meaningful names. + - **Know Your Library**: If you are using a functional programming library like Ramda or fp-ts, invest time in learning the combinators it provides. They are the building blocks for effective use of the library. + - **Use Currying**: Combinators are most powerful in a language that supports currying, as it allows for partial application, creating specialized functions from general ones. + +## Common Pitfalls + + - **"Pointless" Code**: Overuse of point-free style can lead to code that is very difficult to read and debug. The goal is clarity through abstraction, not just character count reduction. + - **Debugging Complexity**: Debugging a long chain of composed functions is challenging because there are no named intermediate values to inspect. You often have to break the chain apart to find the source of a bug. + +## Performance Considerations + + - **Function Call Overhead**: In theory, a deeply nested composition of combinators can introduce a small overhead from the additional function calls. + - **Negligible in Practice**: In most real-world applications, this overhead is negligible and completely optimized away by modern JavaScript engines and language compilers. Code clarity and correctness are far more important concerns. + +## Integration Points + + - **Functional Programming Libraries**: Libraries like **Ramda**, **Lodash/fp**, and the **Haskell Prelude** are essentially collections of combinators and other higher-order functions. + - **Lambda Calculus**: Combinatory logic, the formal study of combinators, is computationally equivalent to lambda calculus. The famous **SKI combinator calculus** (using only S, K, and I combinators) can be used to express any computable algorithm. + - **Parser Combinator Libraries**: Libraries like `parsec` in Haskell or `fast-check` in JavaScript use these principles to build robust parsers and property-based testing tools. + +## Troubleshooting + +### Problem 1: A Composed Function Behaves Incorrectly + +**Symptoms:** The final output of a point-free pipeline is `undefined`, `NaN`, or simply the wrong value. +**Solution:** Temporarily "re-point" the function to debug. Break the composition and insert `console.log` statements (or a `tap` utility function) to inspect the data as it flows from one function to the next. + +```javascript +// A "tap" combinator is useful for debugging. +const tap = (fn) => (x) => { + fn(x); + return x; +}; + +// Insert it into a pipeline to inspect intermediate values. +const problematicPipe = pipe( + increment, + tap(console.log), // See the value after incrementing + double +); +``` + +## Examples in Context + + - **Configuration Objects**: Using the K-combinator (constant function) to provide default configuration values. + - **Data Validation**: Building a validator by composing smaller validation rule functions, where each function takes data and returns either a success or failure indicator. + - **Web Development**: A point-free pipeline in a frontend application that takes a raw API response, filters out inactive items, extracts a specific field, and formats it for display. + +## References + + - [To Mock a Mockingbird by Raymond Smullyan](https://en.wikipedia.org/wiki/To_Mock_a_Mockingbird) - An accessible and famous book that teaches combinatory logic through recreational puzzles. + - [Wikipedia: Combinatory Logic](https://en.wikipedia.org/wiki/Combinatory_logic) + - [Ramda Documentation](https://ramdajs.com/docs/) + +## Related Topics + + - Point-Free Style + - Lambda Calculus + - Functional Programming + - Currying + - Higher-Order Functions \ No newline at end of file diff --git a/bash/talk-to-computer/corpus/programming/command_line_data_processing.md b/bash/talk-to-computer/corpus/programming/command_line_data_processing.md new file mode 100644 index 0000000..c5ce5f5 --- /dev/null +++ b/bash/talk-to-computer/corpus/programming/command_line_data_processing.md @@ -0,0 +1,200 @@ +# Local Data Processing With Unix Tools - Shell-based data wrangling + +## Introduction + +Leveraging standard Unix command-line tools for data processing is a powerful, efficient, and universally available method for handling text-based data. This guide focuses on the **Unix philosophy** of building complex data processing **pipelines** by composing small, single-purpose utilities. This approach is invaluable for ad-hoc data exploration, log analysis, and pre-processing tasks directly within the shell, often outperforming more complex scripts or dedicated software for common data wrangling operations. + +Key applications include analyzing web server logs, filtering and transforming CSV/TSV files, and batch-processing any line-oriented text data. + +## Core Concepts + +### Streams and Redirection + +At the core of Unix inter-process communication are three standard streams: + +1. `stdin` (standard input): The stream of data going into a program. +2. `stdout` (standard output): The primary stream of data coming out of a program. +3. `stderr` (standard error): A secondary output stream for error messages and diagnostics. + +**Redirection** controls these streams. The pipe `|` operator is the most important, as it connects one command's `stdout` to the next command's `stdin`, forming a pipeline. + +```bash +# Redirect stdout to a file (overwrite) +command > output.txt + +# Redirect stdout to a file (append) +command >> output.txt + +# Redirect a file to stdin +command < input.txt + +# Redirect stderr to a file +command 2> error.log + +# Redirect stderr to stdout +command 2>&1 +``` + +### The Core Toolkit + +A small set of highly-specialized tools forms the foundation of most data pipelines. + + - **`grep`**: Filters lines that match a regular expression. + - **`awk`**: A powerful pattern-scanning and processing language. It excels at columnar data, allowing you to manipulate fields within each line. + - **`sed`**: A "stream editor" for performing text transformations on an input stream (e.g., search and replace). + - **`sort`**: Sorts lines of text files. + - **`uniq`**: Reports or omits repeated lines. Often used with `-c` to count occurrences. + - **`cut`**: Removes sections from each line of files (e.g., select specific columns). + - **`tr`**: Translates or deletes characters. + - **`xargs`**: Builds and executes command lines from standard input. It bridges the gap between commands that produce lists of files and commands that operate on them. + +## Key Principles + +The effectiveness of this approach stems from the **Unix Philosophy**: + +1. **Do one thing and do it well**: Each tool is specialized for a single task (e.g., `grep` only filters, `sort` only sorts). +2. **Write programs that work together**: The universal text stream interface (`stdin`/`stdout`) allows for near-infinite combinations of tools. +3. **Handle text streams**: Text is a universal interface, making the tools broadly applicable to a vast range of data formats. + +## Implementation/Usage + +Let's assume we have a web server access log file, `access.log`, with the following format: +`IP_ADDRESS - - [TIMESTAMP] "METHOD /path HTTP/1.1" STATUS_CODE RESPONSE_SIZE` + +Example line: +`192.168.1.10 - - [20/Aug/2025:15:30:00 -0400] "GET /home HTTP/1.1" 200 5120` + +### Basic Example + +**Goal**: Find the top 5 IP addresses that accessed the server. + +```bash +# This pipeline extracts, groups, counts, and sorts the IP addresses. +cat access.log | \ + awk '{print $1}' | \ + sort | \ + uniq -c | \ + sort -nr | \ + head -n 5 +``` + +**Breakdown:** + +1. `cat access.log`: Reads the file and sends its content to `stdout`. +2. `awk '{print $1}'`: For each line, print the first field (the IP address). +3. `sort`: Sorts the IPs alphabetically, which is necessary for `uniq` to group them. +4. `uniq -c`: Collapses adjacent identical lines into one and prepends the count. +5. `sort -nr`: Sorts the result numerically (`-n`) and in reverse (`-r`) order to get the highest counts first. +6. `head -n 5`: Takes the first 5 lines of the sorted output. + +### Advanced Example + +**Goal**: Calculate the total bytes served for all successful (`2xx` status code) `POST` requests. + +```bash +# This pipeline filters for specific requests and sums a column. +grep '"POST ' access.log | \ + grep ' 2[0-9][0-9] ' | \ + awk '{total += $10} END {print total}' +``` + +**Breakdown:** + +1. `grep '"POST ' access.log`: Filters the log for lines containing ` "POST ` (note the space to avoid matching other methods). +2. `grep ' 2[0-9][0-9] '`: Filters the remaining lines for a 2xx status code. The spaces ensure we match the status code field specifically. +3. `awk '{total += $10} END {print total}'`: For each line that passes the filters, `awk` adds the value of the 10th field (response size) to a running `total`. The `END` block executes after all lines are processed, printing the final sum. + +## Common Patterns + +### Pattern 1: Filter-Map-Reduce + +This is a functional programming pattern that maps directly to Unix pipelines. + + - **Filter**: Select a subset of data (`grep`, `head`, `tail`, `awk '/pattern/'`). + - **Map**: Transform each line of data (`awk '{...}'`, `sed 's/.../.../'`, `cut`). + - **Reduce**: Aggregate data into a summary result (`sort | uniq -c`, `wc -l`, `awk '{sum+=$1} END {print sum}'`). + +### Pattern 2: Shuffling (Sort-Based Grouping) + +This is the command-line equivalent of a `GROUP BY` operation in SQL. The pattern is to extract a key, sort by that key to group related records together, and then process each group. + +```bash +# Example: Find the most frequent user agent for each IP address. +# The key here is the IP address ($1). +awk '{print $1, $12}' access.log | \ + sort | \ + uniq -c | \ + sort -k2,2 -k1,1nr | \ + awk 'BEGIN{last=""} {if ($2 != last) {print} last=$2}' +``` + +This advanced pipeline sorts by IP, then by count, and finally uses `awk` to pick the first (highest count) entry for each unique IP. + +## Best Practices + + - **Develop Incrementally**: Build pipelines one command at a time. After adding a `|` and a new command, run it to see if the intermediate output is what you expect. + - **Filter Early**: Place `grep` or other filtering commands as early as possible in the pipeline. This reduces the amount of data that subsequent, potentially more expensive commands like `sort` have to process. + - **Use `set -o pipefail`**: In shell scripts, this option causes a pipeline to return a failure status if *any* command in the pipeline fails, not just the last one. + - **Prefer `awk` for Columns**: For tasks involving multiple columns, `awk` is generally more powerful, readable, and performant than a complex chain of `cut`, `paste`, and shell loops. + - **Beware of Locales**: The `sort` command's behavior is affected by the `LC_ALL` environment variable. For byte-wise sorting, use `LC_ALL=C sort`. + +## Common Pitfalls + + - **Forgetting to Sort Before `uniq`**: `uniq` only operates on adjacent lines. If the data is not sorted, it will not produce correct counts. + - **Greedy Regular Expressions**: A `grep` pattern like ` . ` can match more than intended. Be as specific as possible with your regex. + - **Shell Globbing vs. `grep` Regex**: The wildcards used by the shell (`*`, `?`) are different from those used in regular expressions (`.*`, `.`). + - **Word Splitting on Unquoted Variables**: When used in scripts, variables containing spaces can be split into multiple arguments if not quoted (`"my var"` vs `my var`). + +## Performance Considerations + + - **I/O is King**: These tools are often I/O-bound. Reading from and writing to disk is the slowest part. Use pipelines to avoid creating intermediate files. + - **`awk` vs. `sed` vs. `grep`**: For simple filtering, `grep` is fastest. For simple substitutions, `sed` is fastest. For any field-based logic, `awk` is the right tool and is extremely fast, as it's a single compiled process. + - **GNU Parallel**: For tasks that can be broken into independent chunks (e.g., processing thousands of files), `GNU parallel` can be used to execute pipelines in parallel, dramatically speeding up the work on multi-core systems. + +## Integration Points + + - **Shell Scripting**: These tools are the fundamental building blocks for automation and data processing scripts in `bash`, `zsh`, etc. + - **Data Ingestion Pipelines**: Unix tools are often used as the first step (the "T" in an ELT process) to clean, filter, and normalize raw log files before they are loaded into a database or data warehouse. + - **Other Languages**: Languages like Python (`subprocess`) and Go (`os/exec`) can invoke these command-line tools to leverage their performance and functionality without having to re-implement them. + +## Troubleshooting + +### Problem 1: Pipeline hangs or is extremely slow + +**Symptoms:** The command prompt doesn't return, and there's no output. +**Solution:** This is often caused by a command like `sort` or another tool that needs to read all of its input before producing any output. It may be processing a massive amount of data. + +1. Test your pipeline on a small subset of the data first using `head -n 1000`. +2. Use a tool like `pv` (pipe viewer) in the middle of your pipeline (`... | pv | ...`) to monitor the flow of data and see where it's getting stuck. + +### Problem 2: `xargs` fails on filenames with spaces + +**Symptoms:** An `xargs` command fails with "file not found" errors for files with spaces or special characters in their names. +**Solution:** Use the "null-delimited" mode of `find` and `xargs`, which is designed to handle all possible characters in filenames safely. + +```bash +# Wrong way, will fail on "file name with spaces.txt" +find . -name "*.txt" | xargs rm + +# Correct, safe way +find . -name "*.txt" -print0 | xargs -0 rm +``` + +## Examples in Context + + - **DevOps/SRE**: Quickly grepping through gigabytes of Kubernetes logs to find error messages related to a specific request ID. + - **Bioinformatics**: Processing massive FASTA/FASTQ text files to filter, reformat, or extract sequence data. + - **Security Analysis**: Analyzing `auth.log` files to find failed login attempts, group them by IP, and identify brute-force attacks. + +## References + + - [The GNU Coreutils Manual](https://www.gnu.org/software/coreutils/manual/coreutils.html) + - [The AWK Programming Language (Book by Aho, Kernighan, Weinberger)](https://archive.org/details/pdfy-MgN0H1joIoDVoIC7) + - [Greg's Wiki - Bash Pitfalls](https://mywiki.wooledge.org/BashPitfalls) + +## Related Topics + + - Shell Scripting + - Regular Expressions (Regex) + - AWK Programming + - Data Wrangling \ No newline at end of file diff --git a/bash/talk-to-computer/corpus/programming/functional_programming.md b/bash/talk-to-computer/corpus/programming/functional_programming.md new file mode 100644 index 0000000..2572442 --- /dev/null +++ b/bash/talk-to-computer/corpus/programming/functional_programming.md @@ -0,0 +1,234 @@ +# Functional Programming - A paradigm for declarative, predictable code + +## Introduction + +**Functional Programming (FP)** is a programming paradigm where software is built by composing **pure functions**, avoiding shared state, mutable data, and side-effects. It treats computation as the evaluation of mathematical functions. Instead of describing *how* to achieve a result (imperative programming), you describe *what* the result is (declarative programming). + +This paradigm has gained significant traction because it helps manage the complexity of modern applications, especially those involving concurrency and complex state management. Programs written in a functional style are often easier to reason about, test, and debug. + +## Core Concepts + +### Pure Functions + +A function is **pure** if it adheres to two rules: + +1. **The same input always returns the same output.** The function's return value depends solely on its input arguments. +2. **It produces no side effects.** A side effect is any interaction with the "outside world" from within the function. This includes modifying a global variable, changing an argument, logging to the console, or making a network request. + +<!-- end list --> + +```javascript +// Pure function: predictable and testable +const add = (a, b) => a + b; +add(2, 3); // Always returns 5 + +// Impure function: has a side effect (console.log) +let count = 0; +const incrementWithLog = () => { + count++; // And mutates external state + console.log(`The count is ${count}`); + return count; +}; +``` + +### Immutability + +**Immutability** means that data, once created, cannot be changed. If you need to modify a data structure (like an object or array), you create a new one with the updated values instead of altering the original. This prevents bugs caused by different parts of your application unexpectedly changing the same piece of data. + +```javascript +// Bad: Mutating an object +const user = { name: "Alice", age: 30 }; +const celebrateBirthdayMutable = (person) => { + person.age++; // This modifies the original user object + return person; +}; + +// Good: Returning a new object +const celebrateBirthdayImmutable = (person) => { + return { ...person, age: person.age + 1 }; // Creates a new object +}; + +const newUser = celebrateBirthdayImmutable(user); +// user is still { name: "Alice", age: 30 } +// newUser is { name: "Alice", age: 31 } +``` + +### First-Class and Higher-Order Functions + +In FP, functions are **first-class citizens**. This means they can be treated like any other value: + + * Assigned to variables + * Stored in data structures + * Passed as arguments to other functions + * Returned as values from other functions + +A function that either takes another function as an argument or returns a function is called a **Higher-Order Function**. Common examples are `map`, `filter`, and `reduce`. + +```javascript +const numbers = [1, 2, 3, 4]; +const isEven = (n) => n % 2 === 0; +const double = (n) => n * 2; + +// `filter` and `map` are Higher-Order Functions +const evenDoubled = numbers.filter(isEven).map(double); // [4, 8] +``` + +## Key Principles + + - **Declarative Style**: Focus on *what* the program should accomplish, not *how* it should accomplish it. An SQL query is a great example of a declarative style. + - **No Side Effects**: Isolate side effects from the core logic of your application. This makes your code more predictable. + - **Function Composition**: Build complex functionality by combining small, reusable functions. + - **Referential Transparency**: An expression can be replaced with its value without changing the behavior of the program. This is a natural outcome of using pure functions and immutable data. + +## Implementation/Usage + +The core idea is to create data transformation pipelines. You start with initial data and pass it through a series of functions to produce the final result. + +### Basic Example + +```javascript +// A simple pipeline for processing a list of users +const users = [ + { name: "Alice", active: true, score: 90 }, + { name: "Bob", active: false, score: 80 }, + { name: "Charlie", active: true, score: 95 }, +]; + +/** + * @param {object[]} users + * @returns {string[]} + */ +const getHighScoringActiveUserNames = (users) => { + return users + .filter((user) => user.active) + .filter((user) => user.score > 85) + .map((user) => user.name.toUpperCase()); +}; + +console.log(getHighScoringActiveUserNames(users)); // ["ALICE", "CHARLIE"] +``` + +### Advanced Example + +A common advanced pattern is to use a reducer function to manage application state, a core concept in The Elm Architecture and libraries like Redux. + +```javascript +// The state of our simple counter application +const initialState = { count: 0 }; + +// A pure function that describes how state changes in response to an action +const counterReducer = (state, action) => { + switch (action.type) { + case 'INCREMENT': + return { ...state, count: state.count + 1 }; + case 'DECREMENT': + return { ...state, count: state.count - 1 }; + case 'RESET': + return { ...state, count: 0 }; + default: + return state; + } +}; + +// Simulate dispatching actions +let state = initialState; +state = counterReducer(state, { type: 'INCREMENT' }); // { count: 1 } +state = counterReducer(state, { type: 'INCREMENT' }); // { count: 2 } +state = counterReducer(state, { type: 'DECREMENT' }); // { count: 1 } + +console.log(state); // { count: 1 } +``` + +## Common Patterns + +### Pattern 1: Functor + +A **Functor** is a design pattern for a data structure that can be "mapped over." It's a container that holds a value and has a `map` method for applying a function to that value without changing the container's structure. The most common example is the `Array`. + +```javascript +// Array is a Functor because it has a .map() method +const numbers = [1, 2, 3]; +const addOne = (n) => n + 1; +const result = numbers.map(addOne); // [2, 3, 4] +``` + +### Pattern 2: Monad + +A **Monad** is a pattern for sequencing computations. Think of it as a "safer" functor that knows how to handle nested contexts or operations that can fail (like Promises or the `Maybe` type). `Promise` is a good practical example; its `.then()` method (or `flatMap`) lets you chain asynchronous operations together seamlessly. + +```javascript +// Promise is a Monad, allowing chaining of async operations +const fetchUser = (id) => Promise.resolve({ id, name: "Alice" }); +const fetchUserPosts = (user) => Promise.resolve([ { userId: user.id, title: "Post 1" } ]); + +fetchUser(1) + .then(fetchUserPosts) // .then acts like flatMap here + .then(posts => console.log(posts)) + .catch(err => console.error(err)); +``` + +## Best Practices + + - **Keep Functions Small**: Each function should do one thing well. + - **Use Function Composition**: Use utilities like `pipe` or `compose` to build complex logic from simple building blocks. + - **Embrace Immutability**: Use `const` by default. Avoid reassigning variables. When updating objects or arrays, create new ones. + - **Isolate Impurity**: Side effects are necessary. Keep them at the boundaries of your application (e.g., in the function that handles an API call) and keep your core business logic pure. + +## Common Pitfalls + + - **Accidental Mutation**: JavaScript objects and arrays are passed by reference, making it easy to mutate them accidentally. Be vigilant, especially with nested data. + - **Over-Abstraction**: Don't use complex FP concepts like monad transformers if a simple function will do. Prioritize readability. + - **Performance Misconceptions**: While creating many short-lived objects can have a performance cost, modern JavaScript engines are highly optimized for this pattern. Don't prematurely optimize; measure first. + +## Performance Considerations + + - **Object/Array Creation**: In performance-critical code (e.g., animations, large data processing), the overhead of creating new objects/arrays in a tight loop can be significant. + - **Structural Sharing**: Libraries like `Immer` and `Immutable.js` use a technique called structural sharing. When you "change" an immutable data structure, only the parts that changed are created anew; the rest of the structure points to the same old data, saving memory and CPU time. + - **Recursion**: Deep recursion can lead to stack overflow errors. While some languages support **Tail Call Optimization (TCO)** to prevent this, JavaScript engines have limited support. Prefer iteration for very large data sets. + +## Integration Points + + - **UI Frameworks**: FP concepts are central to modern UI libraries. **React** encourages pure components and uses immutable state patterns with Hooks (`useState`, `useReducer`). + \-- **State Management**: Libraries like **Redux** and **Zustand** are built entirely on FP principles, particularly the use of pure reducer functions. + - **Data Processing**: FP is excellent for data transformation pipelines. It's often used in backend services for processing streams of data. + - **Utility Libraries**: Libraries like **Lodash/fp** and **Ramda** provide a rich toolkit of pre-built, curried, and pure functions for everyday tasks. + +## Troubleshooting + +### Problem 1: Debugging composed function pipelines + +**Symptoms:** A chain of `.map().filter().reduce()` produces an incorrect result, and it's hard to see where it went wrong. +**Solution:** Break the chain apart. Log the intermediate result after each step to inspect the data as it flows through the pipeline. + +```javascript +const result = users + .filter((user) => user.active) + // console.log('After active filter:', resultFromActiveFilter) + .filter((user) => user.score > 85) + // console.log('After score filter:', resultFromScoreFilter) + .map((user) => user.name.toUpperCase()); +``` + +### Problem 2: State changes unexpectedly + +**Symptoms:** A piece of state (e.g., in a React component or Redux store) changes when it shouldn't have, leading to bugs or infinite re-renders. +**Solution:** This is almost always due to accidental mutation. Audit your code to ensure you are not modifying state directly. Use the spread syntax (`...`) for objects and arrays (`[...arr, newItem]`) to create copies. Libraries like `Immer` can make this process safer and more concise. + +## Examples in Context + + - **Frontend Web Development**: The **Elm Architecture** (Model, Update, View) is a purely functional pattern for building web apps. It has heavily influenced libraries like Redux. + - **Data Analysis**: Running a series of transformations on a large dataset to filter, shape, and aggregate it for a report. + - **Concurrency**: Handling multiple events or requests simultaneously without running into race conditions, because data is immutable and shared state is avoided. + +## References + + - [MDN Web Docs: Functional Programming](https://www.google.com/search?q=https://developer.mozilla.org/en-US/docs/Glossary/Functional_programming) + - [Professor Frisby's Mostly Adequate Guide to Functional Programming](https://mostly-adequate.gitbook.io/mostly-adequate-guide/) + - [Ramda Documentation](https://ramdajs.com/docs/) + +## Related Topics + + - Immutability + - Functional Reactive Programming (FRP) + - The Elm Architecture + - Algebraic Data Types \ No newline at end of file diff --git a/bash/talk-to-computer/corpus/programming/lil_guide.md b/bash/talk-to-computer/corpus/programming/lil_guide.md new file mode 100644 index 0000000..72df8df --- /dev/null +++ b/bash/talk-to-computer/corpus/programming/lil_guide.md @@ -0,0 +1,277 @@ +# Multi-paradigm Programming with Lil - A Guide to Lil's Diverse Styles + +## Introduction + +Lil is a richly multi-paradigm scripting language designed for the Decker creative environment. It seamlessly blends concepts from **imperative**, **functional**, **declarative**, and **vector-oriented** programming languages. This flexibility allows developers to choose the most effective and ergonomic approach for a given task, whether it's managing application state, manipulating complex data structures, or performing efficient bulk computations. Understanding these paradigms is key to writing elegant, efficient, and idiomatic Lil code. + +## Core Concepts + +Lil's power comes from the way it integrates four distinct programming styles. + +### Imperative Programming + +This is the traditional, statement-by-statement style of programming. It involves creating variables, assigning values to them, and using loops and conditionals to control the flow of execution. + + - **Assignment:** The colon (`:`) is used for assignment. + - **Control Flow:** Lil provides `if`/`elseif`/`else` for conditionals and `while` and `each` for loops. + - **State Management:** State is typically managed by assigning and re-assigning values to variables, often stored in the properties of Decker widgets between event handlers. + +<!-- end list --> + +```lil +# Imperative approach to summing a list +total: 0 +numbers: [10, 20, 30] +each n in numbers do + total: total + n +end +# total is now 60 +``` + +### Functional Programming + +The functional style emphasizes pure functions, immutability, and the composition of functions without side-effects. + + - **Immutability:** All core data structures (lists, dictionaries, tables) have copy-on-write semantics. Modifying one does not alter the original value but instead returns a new, amended value. + - **First-Class Functions:** Functions are values that can be defined with `on`, assigned to variables, and passed as arguments to other functions. + - **Expressions over Statements:** Every statement in Lil is an expression that returns a value. An `if` block returns the value of its executed branch, and an `each` loop returns a new collection containing the result of each iteration. + +<!-- end list --> + +```lil +# Functional approach using a higher-order function +on twice f x do + f[f[x]] +end + +on double x do + x * 2 +end + +result: twice[double 10] # result is 40 +``` + +### Declarative (Query-based) Programming + +For data manipulation, Lil provides a powerful declarative query engine that resembles SQL. Instead of describing *how* to loop through and filter data, you declare *what* data you want. + + - **Queries:** Use `select`, `update`, and `extract` to query tables (and other collection types). + - **Clauses:** Filter, group, and sort data with `where`, `by`, and `orderby` clauses. + - **Readability:** Queries often result in more concise and readable code for data transformation tasks compared to imperative loops. + +<!-- end list --> + +```lil +# Declarative query to find developers +people: insert name age job with + "Alice" 25 "Development" + "Sam" 28 "Sales" + "Thomas" 40 "Development" +end + +devs: select name from people where job="Development" +# devs is now a table with the names "Alice" and "Thomas" +``` + +### Vector-Oriented Programming + +Influenced by languages like APL and K, this paradigm focuses on applying operations to entire arrays or lists (vectors) at once, a concept known as **conforming**. + + - **Conforming Operators:** Standard arithmetic operators (`+`, `-`, `*`, `/`) work element-wise on lists. + - **Efficiency:** Vector operations are significantly more performant than writing equivalent imperative loops. + - **The `@` Operator:** The "apply" operator (`@`) can be used to apply a function to each element of a list or to select multiple elements from a list by index. + +<!-- end list --> + +```lil +# Vector-oriented approach to add 10 to each number +numbers: [10, 20, 30] +result: numbers + 10 # result is [20, 30, 40] +``` + +----- + +## Key Principles + + - **Right-to-Left Evaluation:** Expressions are evaluated from right to left unless overridden by parentheses `()`. This is a fundamental rule that affects how all expressions are composed. + - **Copy-on-Write Immutability:** Lists, Dictionaries, and Tables are immutable. Operations like `update` or indexed assignments on an expression `(foo)[1]:44` return a new value, leaving the original unchanged. Direct assignment `foo[1]:44` is required to modify the variable `foo` itself. + - **Data-Centric Design:** The language provides powerful, built-in tools for data manipulation, especially through its query engine and vector operations. + - **Lexical Scoping:** Variables are resolved based on their location in the code's structure. Functions "close over" variables from their containing scope, enabling patterns like counters and encapsulated state. + +----- + +## Implementation/Usage + +The true power of Lil emerges when you mix these paradigms to solve problems cleanly and efficiently. + +### Basic Example + +Here, we combine an imperative loop with a vector-oriented operation to process a list of lists. + +```lil +# Calculate the magnitude of several 2D vectors +vectors: [[3,4], [5,12], [8,15]] +magnitudes: [] + +# Imperative loop over the list of vectors +each v in vectors do + # mag is a vector-oriented unary operator + magnitudes: magnitudes & [mag v] +end + +# magnitudes is now [5, 13, 17] +``` + +### Advanced Example + +This example defines a functional-style utility function (`avg`) and uses it within a declarative query to summarize data, an approach common in data analysis. + +```lil +# Functional helper function +on avg x do + (sum x) / count x +end + +# A table of sales data +sales: insert product category price with + "Apple" "Fruit" 0.5 + "Banana" "Fruit" 0.4 + "Bread" "Grain" 2.5 + "Rice" "Grain" 3.0 +end + +# Declarative query that uses the functional helper +avgPriceByCategory: select category:first category avg_price:avg[price] by category from sales + +# avgPriceByCategory is now: +# +----------+-----------+ +# | category | avg_price | +# +----------+-----------+ +# | "Fruit" | 0.45 | +# | "Grain" | 2.75 | +# +----------+-----------+ +``` + +----- + +## Common Patterns + +### Pattern 1: Query over Loop + +Instead of manually iterating with `each` to filter or transform a collection, use a declarative `select` or `extract` query. This is more concise, often faster, and less error-prone. + +```lil +# Instead of this imperative loop... +high_scores: [] +scores: [88, 95, 72, 100, 91] +each s in scores do + if s > 90 then + high_scores: high_scores & [s] + end +end + +# ...use a declarative query. +high_scores: extract value where value > 90 from scores +# high_scores is now [95, 100, 91] +``` + +### Pattern 2: Function Application with `@` + +For simple element-wise transformations on a list, using the `@` operator with a function is cleaner than writing an `each` loop. + +```lil +# Instead of this... +names: ["alice", "bob", "charlie"] +capitalized: [] +on capitalize s do first s & (1 drop s) end # Simple capitalize, for demo +each n in names do + capitalized: capitalized & [capitalize n] +end + +# ...use the more functional and concise @ operator. +on capitalize s do first s & (1 drop s) end +capitalized: capitalize @ names +# capitalized is now ["Alice", "Bob", "Charlie"] +``` + +----- + +## Best Practices + + - **Embrace Queries:** For any non-trivial data filtering, grouping, or transformation, reach for the query engine first. + - **Use Vector Operations:** When performing arithmetic or logical operations on lists, use conforming operators (`+`, `<`, `=`) instead of loops for better performance and clarity. + - **Distinguish Equality:** Use the conforming equals `=` within query expressions. Use the non-conforming match `~` in `if` or `while` conditions to avoid accidentally getting a list result. + - **Encapsulate with Functions:** Use functions to create reusable components and manage scope, especially for complex logic within Decker event handlers. + +----- + +## Common Pitfalls + + - **Right-to-Left Confusion:** Forgetting that `3*2+5` evaluates to `21`, not `11`. Use parentheses `(3*2)+5` to enforce the desired order of operations. + - **Expecting Mutation:** Believing that `update ... from my_table` changes `my_table`. It returns a *new* table. You must reassign it: `my_table: update ... from my_table`. + - **Comma as Argument Separator:** Writing `myfunc[arg1, arg2]`. This creates a list of two items and passes it as a single argument. The correct syntax is `myfunc[arg1 arg2]`. + - **Using `=` in `if`:** Writing `if some_list = some_value` can produce a list of `0`s and `1`s. An empty list `()` is falsey, but a list like `[0,0]` is truthy. Use `~` for a single boolean result in control flow. + +----- + +## Performance Considerations + +Vector-oriented algorithms are significantly faster and more memory-efficient than their imperative, element-by-element counterparts. The Lil interpreter is optimized for these bulk operations. For example, replacing values in a list using a calculated mask is preferable to an `each` loop with a conditional inside. + +```lil +# Slow, iterative approach +x: [1, 10, 2, 20, 3, 30] +result: each v in x + if v < 5 99 else v end +end + +# Fast, vector-oriented approach +mask: x < 5 # results in [1,0,1,0,1,0] +result: (99 * mask) + (x * !mask) +``` + +----- + +## Integration Points + +The primary integration point for Lil is **Decker**. Lil scripts are attached to Decker widgets, cards, and the deck itself to respond to user events (`on click`, `on keydown`, etc.). All paradigms are useful within Decker: + + - **Imperative:** To sequence actions, like showing a dialog and then navigating to another card. + - **Declarative:** To query data stored in a `grid` widget or to find specific cards in the deck, e.g., `extract value where value..widgets.visited.value from deck.cards`. + - **Functional/Vector:** To process data before displaying it, without needing slow loops. + +----- + +## Troubleshooting + +### Problem 1: An `if` statement behaves unpredictably with list comparisons. + + - **Symptoms:** An `if` block either never runs or always runs when comparing a value against a list. + - **Solution:** You are likely using the conforming equals operator (`=`), which returns a list of boolean results. In a conditional, you almost always want the non-conforming match operator (`~`), which returns a single `1` or `0`. + +### Problem 2: A recursive function crashes with a stack overflow on large inputs. + + - **Symptoms:** The script terminates unexpectedly when a recursive function is called with a large number or deep data structure. + - **Solution:** Lil supports **tail-call elimination**. Ensure your recursive call is the very last operation performed in the function. If it's part of a larger expression (e.g., `1 + my_func[...]`), it is not in a tail position. Rewrite the function to accumulate its result in an argument. + +----- + +## Examples in Context + +**Use Case: A Simple To-Do List in Decker** + +Imagine a Decker card with a `grid` widget named "tasks" (with columns "desc" and "done") and a `field` widget named "summary". + +```lil +# In the script of the "tasks" grid, to update when it's changed: +on change do + # Use a DECLARATIVE query to get the done/total counts. + # The query source is "me.value", the table in the grid. + stats: extract done:sum done total:count done from me.value + + # Use IMPERATIVE assignment to update the summary field. + summary.text: format["%d of %d tasks complete.", stats.done, stats.total] +end +``` + +This tiny script uses a declarative query to read the state and an imperative command to update the UI, demonstrating a practical mix of paradigms. diff --git a/bash/talk-to-computer/corpus/science/physics_basics.txt b/bash/talk-to-computer/corpus/science/physics_basics.txt new file mode 100644 index 0000000..5ae092b --- /dev/null +++ b/bash/talk-to-computer/corpus/science/physics_basics.txt @@ -0,0 +1,94 @@ +PHYSICS BASICS - Core Concepts and Principles + +CLASSICAL MECHANICS +================== + +Newton's Laws of Motion: +1.

The \'P\' in pForth stands for \"Portable\". PForth is based +on a Forth kernel written in ANSI standard \'C\'. + +### What is Forth? + +Forth is a stack based language invented by astronomer Charles Moore for +controlling telescopes. Forth is an interactive language. You can enter +commands at the keyboard and have them be immediately executed, similar +to BASIC or LISP. Forth has a dictionary of words that can be executed +or used to construct new words that are then added to the dictionary. +Forth words operate on a data stack that contains numbers and addresses. + +To learn more about Forth, see the [Forth Tutorial](pf_tut.php). + +### The Origins of pForth + +PForth began as a JSR threaded 68000 Forth called HForth that was used +to support [HMSL](/hmsl/), the Hierarchical Music Specification +Language. HMSL was a music experimentation language developed by Phil +Burk, Larry Polansky and David Rosenboom while working at the Mills +College Center for Contemporary Music. Phil moved from Mills to the 3DO +Company where he ported the Forth kernel to \'C\'. It was used +extensively at 3DO as a tool for verifying ASIC design and for bringing +up new hardware platforms. At 3DO, the Forth had to run on many systems +including SUN, SGI, Macintosh, PC, Amiga, the 3DO ARM based Opera +system, and the 3DO PowerPC based M2 system. + +### pForth Design Goals + +PForth has been designed with portability as the primary design goal. As +a result, pForth avoids any fancy UNIX calls. pForth also avoids using +any clever and original ways of constructing the Forth dictionary. It +just compiles its kernel from ANSI compatible \'C\' code then loads ANS +compatible Forth code to build the dictionary. Very boring but very +likely to work on almost any platform. + +The dictionary files that can be saved from pForth are almost host +independent. They can be compiled on one processor, and then run on +another processor. as long as the endian-ness is the same. In other +words, dictionaries built on a PC will only work on a PC. Dictionaries +built on almost any other computer will work on almost any other +computer. + +PForth can be used to bring up minimal hardware systems that have very +few system services implemented. It is possible to compile pForth for +systems that only support routines to send and receive a single +character. If malloc() and free() are not available, equivalent +functions are available in standard \'C\' code. If file I/O is not +available, the dictionary can be saved as a static data array in \'C\' +source format on a host system. The dictionary in \'C\' source form is +then compiled with a custom pForth kernel to avoid having to read the +dictionary from disk. + +------------------------------------------------------------------------ + +## []{#Compiling-pForth-System}Compiling pForth for your System + +Up-to-date instructions on compiling, possibly with comments from the +community, may be found at: + +> [https://github.com/philburk/pforth/wiki/Compiling-on-Unix](https://github.com/philburk/pforth/wiki/Compiling-on-Unix){target="_blank"} + +The process of building pForth involves several steps. This process is +typically handled automatically by the Makefile or IDE Project. + +1. Compile the \'C\' based pForth kernel called \"pforth\" or + \"pforth.exe\". +2. Execute \"pforth\" with the -i option to build the dictionary from + scratch. Compile the \"system.fth\" file which will add all the top + level Forth words. This can be done in one command by entering + \"pforth -i system.fth\". +3. Save the compiled dictionary as \"pforth.dic\". +4. The next time you run pforth, the precompiled pforth.dic file will + be loaded automatically. + +### Unix and Max OS X + +A Makefile has been provided that should work on most Unix based +platforms. + +1. cd to \"platforms/unix\" folder. +2. Enter: make all +3.

The headers (names) will be discarded to save space in +the dictionary. Suppose you have defined a word called MYAPP to prints +the ASCII code when you press a key on the keyboard. + +- : MYAPP ( -- , print key codes ) + BEGIN ." #" key dup ascii q = not + WHILE . cr REPEAT ; + +Save a dictionary named \"turnkey.dic\" that will run MYAPP. Other names +are OK. + +- c" turnkey.dic" ' MYAPP TURNKEY + +Run the app. Press some letters to see the code. Then press \'q\' to +exit. + +- ./pforth -dturnkey.dic + +### []{#Recompiling-Code}Recompiling Code - ANEW INCLUDE? + +When you are testing a file full of code, you will probably recompile +many times. You will probably want to FORGET the old code before loading +the new code. You could put a line at the beginning of your file like +this: + +- FORGET XXXX-MINE : XXXX-MINE ; + +This would automatically FORGET for you every time you load. +Unfortunately, you must define XXXX-MINE before you can ever load this +file. We have a word that will automatically define a word for you the +first time, then FORGET and redefine it each time after that. It is +called ANEW and can be found at the beginning of most Forth source +files. We use a prefix of TASK- followed by the filename just to be +consistent. This TASK-name word is handy when working with INCLUDE? as +well. Here is an example: + +- \ Start of file + INCLUDE? TASK-MYTHING.FTH MYTHING.FTH + ANEW TASK-THISFILE.FTH + \ the rest of the file follows... + +Notice that the INCLUDE? comes before the call to ANEW so that we don\'t +FORGET MYTHING.FTH every time we recompile. + +FORGET allows you to get rid of code that you have already compiled. +This is an unusual feature in a programming language. It is very +convenient in Forth but can cause problems. Most problems with FORGET +involve leaving addresses that point to the forgotten code that are not +themselves forgotten. This can occur if you set a deferred system word +to your word then FORGET your word. The system word which is below your +word in the dictionary is pointing up to code that no longer exists. It +will probably crash if called. (See discussion of DEFER below.) Another +problem is if your code allocates memory, opens files, or opens windows. +If your code is forgotten you may have no way to free or close these +thing. You could also have a problems if you add addresses from your +code to a table that is below your code. This might be a jump table or +data table. + +Since this is a common problem we have provided a tool for handling it. +If you have some code that you know could potentially cause a problem if +forgotten, then write a cleanup word that will eliminate the problem. +This word could UNdefer words, free memory, etc. Then tell the system to +call this word if the code is forgotten. Here is how: + +- : MY.CLEANUP ( -- , do whatever ) + MY-MEM @ FREE DROP + 0 MY-MEM ! + ; + IF.FORGOTTEN MY.CLEANUP + +IF.FORGOTTEN creates a linked list node containing your CFA that is +checked by FORGET. Any nodes that end up above HERE (the Forth pointer +to the top of the dictionary) after FORGET is done are executed. + +### []{#Customising-FORGET}Customising FORGET with \[FORGET\] + +Sometimes, you may need to extend the way that FORGET works. FORGET is +not deferred, however, because that could cause some real problems. +Instead, you can define a new version of \[FORGET\] which is searched +for and executed by FORGET. You MUST call \[FORGET\] from your program +or FORGET will not actually FORGET. Here is an example. + +- : [FORGET] ( -- , my version ) + ." Change things around!" CR + [FORGET] ( must be called ) + ." Now put them back!" CR + ; + : FOO ." Hello!" ; + FORGET FOO ( Will print "Change things around!", etc.) + +This is recommended over redefining FORGET because words like ANEW that +call FORGET will now pick up your changes. + +### []{#Smart-Conditionals}Smart Conditionals + +In pForth, you can use IF THEN DO LOOP and other conditionals outside of +colon definitions. PForth will switch temporarily into the compile +state, then automatically execute the conditional code. (Thank you Mitch +Bradley) For example, just enter this at the keyboard. + +- 10 0 DO I . LOOP + +### []{#Development-Tools}Development Tools + +#### []{#WORDS.LIKE}WORDS.LIKE + +If you cannot remember the exact name of a word, you can use WORDS.LIKE +to search the dictionary for all words that contain a substring.

If a +word was defined in multiple files then it will list each file. The +execution token of each definition of the word is listed on the same +line. + +- FILE? IF + FILE? AUTO.INIT + +#### []{#SEE}SEE + +You can use SEE to \"disassemble\" a word in the pForth dictionary. SEE +will attempt to print out Forth source in a form that is similar to the +source code. SEE will give you some idea of how the word was defined but +is not perfect. Certain compiler words, like BEGIN and LITERAL, are +difficult to disassemble and may not print properly. For an example, +enter: + +- SEE SPACES + SEE WORDS + +#### []{#single-step-trace}Single Step Trace and Debug + +It is often useful to proceed step by step through your code when +debugging. PForth provides a simple single step trace facility for this +purpose. Here is an example of using TRACE to debug a simple program. +Enter the following program:\ + + +- : SQUARE ( n -- n**2 ) + DUP * + ; + : TSQ ( n -- , test square ) + ." Square of " DUP . + ." is " SQUARE . CR + ; + +Even though this program should work, let\'s pretend it doesn\'t and try +to debug it.

Square of " >> ok + +The \"TSQ +0\" means that you are about to execute code at an offset of +\"+0\" from the beginning of TSQ. The \<10:1\> means that we are in +base 10, and that there is 1 item on the stack, which is shown to be +\"7\". The (.\") is the word that is about to be executed. (.\") is the +word that is compiled when use use .\". Now to single step, enter: + +- s + +You should see: + +- Square of + << TSQ +16 <10:1> 7 || DUP >> ok + +The \"Square os\" was printed by (.\"). We can step multiple times using +the \"sm\" command.

If we entered +\"s\", we would step over the SQUARE word. If we want to dive down into +SQUARE, we can enter: + +- sd + +You should see: + +- << SQUARE +0 <10:1> 7 || DUP >> ok + +To step once in SQUARE, enter: + +- s + +You should see: + +- << SQUARE +4 <10:2> 7 7 || * >> ok + +To go to the end of the current word, enter: + +- g + +You should see: + +- << SQUARE +8 <10:1> 49 || EXIT >> + << TSQ +36 <10:1> 49 || . >> ok + +EXIT is compiled at the end of every Forth word.

If you find you are doing a lot of stack +operations like DUP SWAP ROT PICK etc. then you may want to use local +variables. They can greatly simplify your code. You can declare local +variables for a word using a syntax similar to the stack diagram. These +variables will only be accessible within that word. Thus they are +\"local\" as opposed to \"global\" like regular variables. Local +variables are self-fetching. They automatically put their values on the +stack when you give their name. You don\'t need to @ the contents. Local +variables do not take up space in the dictionary. They reside on the +return stack where space is made for them as needed. Words written with +them can be reentrant and recursive. + +Consider a word that calculates the difference of two squares, Here are +two ways of writing the same word. + +- : DIFF.SQUARES ( A B -- A*A-B*B ) + DUP * + SWAP DUP * + SWAP - + ; + ( or ) + : DIFF.SQUARES { A B -- A*A-B*B } + A A * + B B * - + ; + 3 2 DIFF.SQUARES ( would return 5 ) + +In the second definition of DIFF.SQUARES the curly bracket \'{\' told +the compiler to start declaring local variables. Two locals were +defined, A and B. The names could be as long as regular Forth words if +desired. The \"\--\" marked the end of the local variable list. When the +word is executed, the values will automatically be pulled from the stack +and placed in the local variables. When a local variable is executed it +places its value on the stack instead of its address. This is called +self-fetching. Since there is no address, you may wonder how you can +store into a local variable. There is a special operator for local +variables that does a store. It looks like -\> and is pronounced \"to\". + +Local variables need not be passed on the stack. You can declare a local +variable by placing it after a \"vertical bar\" ( \| )character. These +are automatically set to zero when created. Here is a simple example +that uses -\> and \| in a word: + +- : SHOW2* + { loc1 | unvar -- , 1 regular, 1 uninitialized } + LOC1 2* -> UNVAR + (set unver to 2*LOC1 ) + UNVAR . ( print UNVAR ) + ; + 3 SHOW2* ( pass only 1 parameter, prints 6 ) + +Since local variable often used as counters or accumulators, we have a +special operator for adding to a local variable It is +-\> which is +pronounced \"plus to\". These next two lines are functionally equivalent +but the second line is faster and smaller: + +- ACCUM 10 + -> ACCUM + 10 +-> ACCUM + +If you name a local variable the same as a Forth word in the dictionary, +eg. INDEX or COUNT, you will be given a warning message. The local +variable will still work but one could easily get confused so we warn +you about this. Other errors that can occur include, missing a closing +\'}\', missing \'\--\', or having too many local variables. + +### []{#C-Structures}\'C\' like Structures. :STRUCT + +You can define \'C\' like data structures in pForth using :STRUCT. For +example: + +- :STRUCT SONG + LONG SONG_NUMNOTES \ define 32 bit structure member named SONG_NUMNOTES + SHORT SONG_SECONDS \ define 16 bit structure member + BYTE SONG_QUALITY \ define 8 bit member + LONG SONG_NUMBYTES \ auto aligns after SHORT or BYTE + RPTR SONG_DATA \ relocatable pointer to data + ;STRUCT + + SONG HAPPY \ define a song structure called happy + + 400 HAPPY S!

SONG_DATA \ store pointer in relocatable form + + HAPPY DST SONG \ dump HAPPY as a SONG structure + + HAPPY S@ SONG_NUMNOTES . \ fetch numnotes and print + +See the file \"c_struct.fth\" for more information. + +### []{#Vectorred-Execution}Vectorred Execution - DEFER + +Using DEFER for vectored words. In Forth and other languages you can +save the address of a function in a variable. You can later fetch from +that variable and execute the function it points to.This is called +vectored execution. PForth provides a tool that simplifies this process. +You can define a word using DEFER. This word will contain the execution +token of another Forth function. When you execute the deferred word, it +will execute the function it points to. By changing the contents of this +deferred word, you can change what it will do. There are several words +that support this process. + +DEFER ( \<name\> \-- , define a deferred word ) + +IS ( CFA \<name\> \-- , set the function for a deferred word ) + +WHAT\'S ( \<name\> \-- CFA , return the CFA set by IS ) + +Simple way to see the name of what\'s in a deferred word: + +- - WHAT'S EMIT >NAME ID. + +should print name of current word that\'s in EMIT. + +Here is an example that uses a deferred word. + +- DEFER PRINTIT + ' . IS PRINTIT ( make PRINTIT use . ) + 8 3 + PRINTIT + + : COUNTUP ( -- , call deferred word ) + ." Hit RETURN to stop!" CR + 0 ( first value ) + BEGIN 1+ DUP PRINTIT CR + ?TERMINAL + UNTIL + ; + COUNTUP ( uses simple . ) + + : FANCY.PRINT ( N -- , print in DECIMAL and HEX) + DUP ." DECIMAL = " . + ." , HEX = " .HEX + ; + ' FANCY.PRINT IS PRINTIT ( change printit ) + WHAT'S PRINTIT >NAME ID. ( shows use of WHAT'S ) + 8 3 + PRINTIT + COUNTUP ( notice that it now uses FANCY.PRINT ) + +Many words in the system have been defined using DEFER which means that +we can change how they work without recompiling the entire system. Here +is a partial list of those words + +- ABORT EMIT NUMBER? + +#### Potential Problems with Defer + +Deferred words are very handy to use, however, you must be careful with +them. One problem that can occur is if you initialize a deferred system +more than once. In the below example, suppose we called STUTTER twice. +The first time we would save the original EMIT vector in OLD-EMIT and +put in a new one. The second time we called it we would take our new +function from EMIT and save it in OLD-EMIT overwriting what we had saved +previously. Thus we would lose the original vector for EMIT . You can +avoid this if you check to see whether you have already done the defer. +Here\'s an example of this technique. + +- DEFER OLD-EMIT + ' QUIT IS OLD-EMIT ( set to known value ) + : EEMMIITT ( char --- , our fun EMIT ) + DUP OLD-EMIT OLD-EMIT + ; + : STUTTER ( --- ) + WHAT'S OLD-EMIT 'C QUIT = ( still the same? ) + IF ( this must be the first time ) + WHAT'S EMIT ( get the current value of EMIT ) + IS OLD-EMIT ( save this value in OLD-EMIT ) + 'C EEMMIITT IS EMIT + ELSE ." Attempt to STUTTER twice!" CR + THEN + ; + : STOP-IT! ( --- ) + WHAT'S OLD-EMIT ' QUIT = + IF ." STUTTER not installed!" CR + + ELSE WHAT'S OLD-EMIT IS EMIT + 'C QUIT IS OLD-EMIT + ( reset to show termination ) + THEN + ; + +In the above example, we could call STUTTER or STOP-IT! as many times as +we want and still be safe. + +Suppose you forget your word that EMIT now calls. As you compile new +code you will overwrite the code that EMIT calls and it will crash +miserably. You must reset any deferred words that call your code before +you FORGET your code. The easiest way to do this is to use the word +IF.FORGOTTEN to specify a cleanup word to be called if you ever FORGET +the code in question. In the above example using EMIT , we could have +said: + +- IF.FORGOTTEN STOP-IT! + +### []{#Floating-Point}Floating Point + +PForth supports the FLOAT word set and much of the FLOATEXT word set as +a compile time option.

This is useful when bringing up +new computer systems. On UNIX systems, you can use the supplied gmake +target. Simply enter: + +- gmake pfemb + +For other systems, here are the steps to create an embedded pForth. + +1. Determine whether your target system has a different endian-ness + than your host system. If the address of a long word is the address + of the most significant byte, then it is \"big endian\". Examples of + big endian processors are Sparc, Motorola 680x0 and PowerPC60x. If + the address of a long word is the address of the least significant + byte, then it is \"Little Endian\". Examples of little endian + processors are Intel 8088 and derivatives such as the Intel Pentium, + X86. ARM processors can be configured as either big or little + endian. +2. If your target system has a different endian-ness than your host + system, then you must compile a version of pForth for your host that + matches the target. Rebuild pForth with either PF_BIG_ENDIAN_DIC or + PF_LITTLE_ENDIAN_DIC defined. You will need to rebuild pforth.dic + as well as the executable Forth. If you do not specify one of these + variables, then the dictionary will match the native endian-ness of + the host processor. +3. Execute pForth. Notice the message regarding the endian-ness of the + dictionary. +4. Compile your custom Forth words on the host development system. +5. Compile the pForth utulity \"utils/savedicd.fth\". +6. Enter in pForth: SDAD +7. SDAD will generate a file called \"pfdicdat.h\" that contains your + dictionary in source code form. +8. Rewrite the character primitives sdTerminalOut(), sdTerminalIn() and + sdTerminalFlush() defined in pf_io.h to use your new computers + communications port. +9. Write a \"user_chario.h\" file based on the API defined in + \"pf_io.h\". +10. Compile a new version of pForth for your target machine with the + following options: + 1. -DPF_NO_INIT -DPF_NO_MALLOC -DPF_NO_FILEIO \ + -DPF_USER_CHARIO="user_chario.h" \ + -DPF_NO_CLIB -DPF_STATIC_DIC +11. The file \"pfdicdat.h\" will be compiled into this executable and + your dictionary will thus be included in the pForth executable as a + static array. +12. Burn a ROM with your new pForth and run it on your target machine. +13. If you compiled a version of pForth with different endian-ness than + your host system, do not use it for daily operation because it will + be much slower than a native version. + +### []{#Link-Custom-C}Linking with Custom \'C\' Functions + +You can call the pForth interpreter as an embedded tool in a \'C\' +application. For an example of this, see the file pf_main.c. This +application does nothing but load the dictionary and call the pForth +interpreter. + +You can call \'C\' from pForth by adding your own custom \'C\' functions +to a dispatch table, and then adding Forth words to the dictionary that +call those functions. See the file \"pfcustom.c\" for more information. + +### []{#Testing-pForth}Testing your Compiled pForth + +Once you have compiled pForth, you can test it using the small +verification suite we provide. The first test you should run was +written by John Hayes at John Hopkins University. Enter: + +- pforth + include tester.fth + include coretest.fth + bye + +The output will be self explanatory. There are also a number of tests +that I have added that print the number of successes and failures. +Enter: + +- pforth t_corex.fth + pforth t_locals.fth + pforth t_strings.fth + pforth t_floats.ft + +Note that t_corex.fth reveals an expected error because SAVE-INPUT is +not fully implemented.

It is only a starting +point. Feel free to deviate from the sequences I provide. A free form +investigation that is based on your curiosity is probably the best way +to learn any language. Forth is especially well adapted to this type of +learning. + +This tutorial is written for the PForth implementation of the ANS Forth +standard. I have tried to restrict this tutorial to words that are part +of the ANS standard but some PForth specific words may have crept in. + +In the tutorials, I will print the things you need to type in upper +case, and indent them. You can enter them in upper or lower case. At the +end of each line, press the RETURN (or ENTER) key; this causes Forth to +interpret what you\'ve entered. + +## []{#Forth Syntax}Forth Syntax + +Forth has one of the simplest syntaxes of any computer language. The +syntax can be stated as follows, \"**Forth code is a bunch of words with +spaces between them.**\" This is even simpler than English! Each *word* +is equivalent to a function or subroutine in a language like \'C\'. They +are executed in the order they appear in the code. The following +statement, for example, could appear in a Forth program: + +- WAKE.UP EAT.BREAKFAST WORK EAT.DINNER PLAY SLEEP + +Notice that WAKE.UP has a dot between the WAKE and UP. The dot has no +particular meaning to the Forth compiler. I simply used a dot to connect +the two words together to make one word. Forth word names can have any +combination of letters, numbers, or punctuation. We will encounter words +with names like: + +- ." #S SWAP ! @ ACCEPT . * + +They are all called *words*. The word **\$%%-GL7OP** is a legal Forth +name, although not a very good one. It is up to the programmer to name +words in a sensible manner. + +Now it is time to run your Forth and begin experimenting. Please consult +the manual for your Forth for instructions on how to run it. + +## []{#The Stack}Stack Manipulation + +The Forth language is based on the concept of a *stack*. Imagine a stack +of blocks with numbers on them. You can add or remove numbers from the +top of the stack. You can also rearrange the order of the numbers. Forth +uses several stacks. The *DataStack* is the one used for passing data +between Forth words so we will concentrate our attention there. The +*Return Stack* is another Forth stack that is primarily for internal +system use. In this tutorial, when we refer to the \"stack,\" we will be +referring to the Data Stack. + +The stack is initially empty. To put some numbers on the stack, enter: + +- 23 7 9182 + +Let\'s now print the number on top of the stack using the Forth word \' +**.** \', which is pronounced \" dot \". This is a hard word to write +about in a manual because it is a single period. + +Enter: **. ** + +You should see the last number you entered, 9182 , printed. Forth has a +very handy word for showing you what\'s on the stack. It is **.S** , +which is pronounced \"dot S\". The name was constructed from \"dot\" for +print, and \"S\" for stack. (PForth will automatically print the stack +after every line if the TRACE-STACK variable is set to TRUE.) If you +enter: + +- .S + +you will see your numbers in a list. The number at the far right is the +one on top of the stack. + +You will notice that the 9182 is not on the stack. The word \' . \' +removes the number on top of the stack before printing it. In contrast, +\' .S \' leaves the stack untouched. + +We have a way of documenting the effect of words on the stack with a +*stack diagram*. A stack diagram is contained in parentheses. In Forth, +the parentheses indicate a comment. In the examples that follow, you do +not need to type in the comments. When you are programming, of course, +we encourage the use of comments and stack diagrams to make your code +more readable. In this manual, we often indicate stack diagrams in +**bold text** like the one that follows. Do not type these in. The stack +diagram for a word like \' . \' would be: + +**`. ( N -- , print number on top of stack )`** + +The symbols to the left of \-- describe the parameters that a word +expects to process. In this example, N stands for any integer number. To +the right of \--, up to the comma, is a description of the stack +parameters when the word is finished, in this case there are none +because \'dot\' \"eats\" the N that was passed in. (Note that the stack +descriptions are not necessary, but they are a great help when learning +other peoples programs.) + +The text following the comma is an English description of the word. You +will note that after the \-- , N is gone. You may be concerned about the +fact that there were other numbers on the stack, namely 23 and 7 . The +stack diagram, however, only describes the portion of the stack that is +affected by the word. For a more detailed description of the stack +diagrams, there is a special section on them in this manual right before +the main glossary section. + +Between examples, you will probably want to clear the stack. If you +enter **0SP**, pronounced \"zero S P\", then the stack will be cleared. + +Since the stack is central to Forth, it is important to be able to alter +the stack easily. Let\'s look at some more words that manipulate the +stack. Enter: + +- 0SP .S \ That's a 'zero' 0, not an 'oh' O. + 777 DUP .S + +You will notice that there are two copies of 777 on the stack. The word +**DUP** duplicates the top item on the stack. This is useful when you +want to use the number on top of the stack and still have a copy. The +stack diagram for DUP would be: + +**`DUP ( n -- n n , DUPlicate top of stack )`** + +Another useful word, is **SWAP**. Enter: + +- 0SP + 23 7 .S + SWAP .S + SWAP .S + +The stack diagram for SWAP would be: + +**`SWAP ( a b -- b a , swap top two items on stack )`** + +Now enter: + +- OVER .S + OVER .S + +The word **OVER** causes a copy of the second item on the stack to +leapfrog over the first. It\'s stack diagram would be: + +**`OVER ( a b -- a b a , copy second item on stack )`** + +Here is another commonly used Forth word: + +**`DROP ( a -- , remove item from the stack )`** + +Can you guess what we will see if we enter: + +- 0SP 11 22 .S + DROP .S + +Another handy word for manipulating the stack is **ROT**. Enter: + +- 0SP + 11 22 33 44 .S + ROT .S + +The stack diagram for ROT is, therefore: + +**`ROT ( a b c -- b c a , ROTate third item to top ) `** + +You have now learned the more important stack manipulation words. You +will see these in almost every Forth program. I should caution you that +if you see too many stack manipulation words being used in your code +then you may want to reexamine and perhaps reorganize your code. You +will often find that you can avoid excessive stack manipulations by +using *local or global VARIABLES* which will be discussed later. + +If you want to grab any arbitrary item on the stack, use **PICK** . Try +entering: + +- 0SP + 14 13 12 11 10 + 3 PICK . ( prints 13 ) + 0 PICK . ( prints 10 ) + 4 PICK . + +PICK makes a copy of the Nth item on the stack. The numbering starts +with zero, therefore: + +- `0 PICK is equivalent to DUP`\ + `1 PICK is equivalent to OVER` + +**`PICK ( ... v3 v2 v1 v0 N -- ... v3 v2 v1 v0 vN ) `** + +(Warning. The Forth-79 and FIG Forth standards differ from the ANS and +Forth \'83 standard in that their PICK numbering starts with one, not +zero.) + +I have included the stack diagrams for some other useful stack +manipulation words. Try experimenting with them by putting numbers on +the stack and calling them to get a feel for what they do. Again, the +text in parentheses is just a comment and need not be entered. + +**`DROP ( n -- , remove top of stack ) `** + +**`?DUP ( n -- n n | 0 , duplicate only if non-zero, '|' means OR ) `** + +**`-ROT ( a b c -- c a b , rotate top to third position ) `** + +**`2SWAP ( a b c d -- c d a b , swap pairs ) `** + +**`2OVER ( a b c d -- a b c d a b , leapfrog pair ) `** + +**`2DUP ( a b -- a b a b , duplicate pair ) `** + +**`2DROP ( a b -- , remove pair ) `** + +**`NIP ( a b -- b , remove second item from stack ) `** + +**`TUCK ( a b -- b a b , copy top item to third position ) `** + +### []{#Problems - Stack}Problems: + +Start each problem by entering: + +- 0SP 11 22 33 + +Then use the stack manipulation words you have learned to end up with +the following numbers on the stack: + +- 1) 11 33 22 22 + + 2) 22 33 + + 3) 22 33 11 11 22 + + 4) 11 33 22 33 11 + + 5) 33 11 22 11 22 + +[Answers to the problems](#Answers%20to%20Problems) can be found at the +end of this tutorial. + +## []{#Arithmetic}Arithmetic + +Great joy can be derived from simply moving numbers around on a stack. +Eventually, however, you\'ll want to do something useful with them. This +section describes how to perform arithmetic operations in Forth. + +The Forth arithmetic operators work on the numbers currently on top of +the stack. If you want to add the top two numbers together, use the +Forth word **+** , pronounced \"plus\". Enter: + +- 2 3 + . + 2 3 + 10 + . + +This style of expressing arithmetic operations is called *Reverse Polish +Notation,* or *RPN*. It will already be familiar to those of you with HP +calculators. In the following examples, I have put the algebraic +equivalent representation in a comment. + +Some other arithmetic operators are **- \* /** . Enter: + +- 30 5 - . ( 25=30-5 ) + 30 5 / . ( 6=30/5 ) + 30 5 * . ( 150=30*5 ) + 30 5 + 7 / . \ 5=(30+5)/7 + +Some combinations of operations are very common and have been coded in +assembly language for speed. For example, **2\*** is short for 2 \* . +You should use these whenever possible to increase the speed of your +program. These include: + +- 1+ 1- 2+ 2- 2* 2/ + +Try entering: + +- 10 1- . + 7 2* 1+ . ( 15=7*2+1 ) + +One thing that you should be aware of is that when you are doing +division with integers using / , the remainder is lost. Enter: + +- 15 5 / . + 17 5 / . + +This is true in all languages on all computers. Later we will examine +**/MOD** and **MOD** which do give the remainder. + +## []{#Defining a New Word}Defining a New Word + +It\'s now time to write a *small program* in Forth. You can do this by +defining a new word that is a combination of words we have already +learned. Let\'s define and test a new word that takes the average of two +numbers. + +We will make use of two new words, **:** ( \"colon\"), and **;** ( +\"semicolon\") . These words start and end a typical *Forth definition*. +Enter: + +- : AVERAGE ( a b -- avg ) + 2/ ; + +Congratulations. You have just written a Forth program. Let\'s look more +closely at what just happened. The colon told Forth to add a new word to +its list of words. This list is called the Forth dictionary. The name of +the new word will be whatever name follows the colon. Any Forth words +entered after the name will be compiled into the new word. This +continues until the semicolon is reached which finishes the definition. + +Let\'s test this word by entering: + +- 10 20 AVERAGE . ( should print 15 ) + +Once a word has been defined, it can be used to define more words. +Let\'s write a word that tests our word.. Enter: + +- : TEST ( --) 50 60 AVERAGE . ; + TEST + +Try combining some of the words you have learned into new Forth +definitions of your choice. If you promise not to be overwhelmed, you +can get a list of the words that are available for programming by +entering: + +- WORDS + +Don\'t worry, only a small fraction of these will be used directly in +your programs. + +## []{#More Arithmetic}More Arithmetic + +When you need to know the remainder of a divide operation. /MOD will +return the remainder as well as the quotient. the word MOD will only +return the remainder. Enter: + +- 0SP + 53 10 /MOD .S + 0SP + 7 5 MOD .S + +Two other handy words are **MIN** and **MAX** . They accept two numbers +and return the MINimum or MAXimum value respectively. Try entering the +following: + +- 56 34 MAX . + 56 34 MIN . + -17 0 MIN . + +Some other useful words are: + +**`ABS ( n -- abs(n) , absolute value of n ) `** + +**`NEGATE ( n -- -n , negate value, faster then -1 * ) `** + +**`LSHIFT ( n c -- n<<c , left shift of n ) `** + +**`RSHIFT ( n c -- n>>c , logical right shift of n ) `** + +**`ARSHIFT ( n c -- n>>c ) , arithmetic right shift of n ) `** + +ARSHIFT or LSHIFT can be used if you have to multiply quickly by a power +of 2 . A right shift is like doing a divide by 2. This is often faster +than doing a regular multiply or divide. Try entering: + +- : 256* 8 LSHIFT ; + 3 256* . + +### []{#Arithmetic Overflow}Arithmetic Overflow + +If you are having problems with your calculation overflowing the 32-bit +precision of the stack, then you can use **\*/** .

The top number +might be how many blue whales are left on Earth or your weight in +kilograms. It can also be an ASCII character. Try entering the +following: + +- 72 EMIT 105 EMIT + +You should see the word \"Hi\" appear before the OK. The 72 is an ASCII +\'H\' and 105 is an \'i\'. EMIT takes the number on the stack and +outputs it as a character. If you want to find the ASCII value for any +character, you can use the word ASCII . Enter: + +- CHAR W . + CHAR % DUP . EMIT + CHAR A DUP . + 32 + EMIT + +Here is a complete [ASCII chart](http://www.asciitable.com/). + +Notice that the word CHAR is a bit unusual because its input comes not +from the stack, but from the following text. In a stack diagram, we +represent that by putting the input in angle brackets, \<input\>. Here +is the stack diagram for CHAR. + +**`CHAR ( <char> -- char , get ASCII value of a character ) `** + +Using EMIT to output character strings would be very tedious. Luckily +there is a better way. Enter: + +- : TOFU ." Yummy bean curd!" ; + TOFU + +The word **.\"** , pronounced \"dot quote\", will take everything up to +the next quotation mark and print it to the screen.

Go back into the +editor and make the following changes: (1) Change TEST.SQUARE to use 15 +instead of 7 then (2) Add this line right before the definition of +SQUARE: + +- ANEW TASK-SAMPLE.FTH + +Now Save your changes and go back to the Forth window. + +You\'re probably wondering what the line starting with **ANEW** was for. +ANEW is always used at the beginning of a file. It defines a special +marker word in the dictionary before the code. The word typically has +\"TASK-\" as a prefix followed by the name of the file. When you +ReInclude a file, ANEW will automatically FORGET the old code starting +after the ANEW statement. This allows you to Include a file over and +over again without having to manually FORGET the first word. If the code +was not forgotten, the dictionary would eventually fill up. + +If you have a big project that needs lots of files, you can have a file +that will load all the files you need. Sometimes you need some code to +be loaded that may already be loaded. The word **INCLUDE?** will only +load code if it isn\'t already in the dictionary. In this next example, +I assume the file is on the volume WORK: and called SAMPLE. If not, +please substitute the actual name. Enter: + +- FORGET TASK-SAMPLE.FTH + INCLUDE? SQUARE WORK:SAMPLE + INCLUDE? SQUARE WORK:SAMPLE + +Only the first INCLUDE? will result in the file being loaded. + +## []{#Variables}Variables + +Forth does not rely as heavily on the use of variables as other compiled +languages. This is because values normally reside on the stack. There +are situations, of course, where variables are required. To create a +variable, use the word **VARIABLE** as follows: + +- VARIABLE MY-VAR + +This created a variable named MY-VAR . A space in memory is now reserved +to hold its 32-bit value. The word VARIABLE is what\'s known as a +\"defining word\" since it creates new words in the dictionary. Now +enter: + +- MY-VAR . + +The number you see is the address, or location, of the memory that was +reserved for MY-VAR. To store data into memory you use the word **!** , +pronounced \"store\". It looks like an exclamation point, but to a Forth +programmer it is the way to write 32-bit data to memory. To read the +value contained in memory at a given address, use the Forth word **@** , +pronounced \"fetch\". Try entering the following: + +- 513 MY-VAR ! + MY-VAR @ . + +This sets the variable MY-VAR to 513 , then reads the value back and +prints it. The stack diagrams for these words follows: + +**`@ ( address -- value , FETCH value FROM address in memory ) `** + +**`! ( value address -- , STORE value TO address in memory )`** + +**`VARIABLE ( <name> -- , define a 4 byte memory storage location)`** + +A handy word for checking the value of a variable is **?** , pronounced +\"question\". Try entering: + +- MY-VAR ? + +If ? wasn\'t defined, we could define it as: + +- : ? ( address -- , look at variable ) + @ . + ; + +Imagine you are writing a game and you want to keep track of the highest +score. You could keep the highest score in a variable. When you reported +a new score, you could check it aginst the highest score. Try entering +this code in a file as described in the previous section: + +- VARIABLE HIGH-SCORE + + : REPORT.SCORE ( score -- , print out score ) + DUP CR ." Your Score = " . CR + HIGH-SCORE @ MAX ( calculate new high ) + DUP ." Highest Score = " . CR + HIGH-SCORE ! ( update variable ) + ; + +Save the file to disk, then compile this code using the INCLUDE word. +Test your word as follows: + +- 123 REPORT.SCORE + 9845 REPORT.SCORE + 534 REPORT.SCORE + +The Forth words @ and ! work on 32-bit quantities. Some Forths are +\"16-bit\" Forths. They fetch and store 16-bit quantities. Forth has +some words that will work on 8 and 16-bit values. C@ and C! work +characters which are usually for 8-bit bytes. The \'C\' stands for +\"Character\" since ASCII characters are 8-bit numbers. Use W@ and W! +for 16-bit \"Words.\" + +Another useful word is **+!** , pronounced \"plus store.\" It adds a +value to a 32-bit value in memory. Try: + +- 20 MY-VAR ! + 5 MY-VAR +! + MY-VAR @ . + +Forth also provides some other words that are similar to VARIABLE. Look +in the glossary for VALUE and ARRAY. Also look at the section on +\"[local variables](pf_ref.php#Local%20Variables%20%7B%20foo%20--%7D?)\" +which are variables which only exist on the stack while a Forth word is +executing. + +*A word of warning about fetching and storing to memory*: You have now +learned enough about Forth to be dangerous. The operation of a computer +is based on having the right numbers in the right place in memory. You +now know how to write new numbers to any place in memory. Since an +address is just a number, you could, but shouldn\'t, enter: + +- 73 253000 ! ( Do NOT do this. ) + +The 253000 would be treated as an address and you would set that memory +location to 73. I have no idea what will happen after that, maybe +nothing. This would be like firing a rifle through the walls of your +apartment building. You don\'t know who or what you are going to hit. +Since you share memory with other programs including the operating +system, you could easily cause the computer to behave strangely, even +crash. Don\'t let this bother you too much, however. Crashing a +computer, unlike crashing a car, does not hurt the computer. You just +have to reboot. The worst that could happen is that if you crash while +the computer is writing to a disk, you could lose a file. That\'s why we +make backups. This same potential problem exists in any powerful +language, not just Forth. This might be less likely in BASIC, however, +because BASIC protects you from a lot of things, including the danger of +writing powerful programs. + +Another way to get into trouble is to do what\'s called an \"odd address +memory access.\" The 68000 processor arranges words and longwords, 16 +and 32 bit numbers, on even addresses. If you do a **@** or **!** , or +**W@** or **W!** , to an odd address, the 68000 processor will take +exception to this and try to abort. + +Forth gives you some protection from this by trapping this exception and +returning you to the OK prompt. If you really need to access data on an +odd address, check out the words **ODD@** and **ODD!** in the glossary. +**C@** and **C!** work fine on both odd and even addresses. + +## []{#Constants}Constants + +If you have a number that is appearing often in your program, we +recommend that you define it as a \"constant.\" Enter: + +- 128 CONSTANT MAX_CHARS + MAX_CHARS . + +We just defined a word called MAX_CHARS that returns the value on the +stack when it was defined. It cannot be changed unless you edit the +program and recompile. Using **CONSTANT** can improve the readability of +your programs and reduce some bugs. Imagine if you refer to the number +128 very often in your program, say 8 times. Then you decide to change +this number to 256. If you globally change 128 to 256 you might change +something you didn\'t intend to. If you change it by hand you might miss +one, especially if your program occupies more than one file. Using +CONSTANT will make it easy to change. The code that results is equally +as fast and small as putting the numbers in directly. I recommend +defining a constant for almost any number. + +## []{#Logical Operators}Logical Operators + +These next two sections are concerned with decision making. This first +section deals with answering questions like \"Is this value too large?\" +or \"Does the guess match the answer?\". The answers to questions like +these are either TRUE or FALSE. Forth uses a 0 to represent **FALSE** +and a -1 to represent **TRUE**. TRUE and FALSE have been capitalized +because they have been defined as Forth constants. Try entering: + +- 23 71 = . + 18 18 = . + +You will notice that the first line printed a 0, or FALSE, and the +second line a -1, or TRUE. The equal sign in Forth is used as a +question, not a statement. It asks whether the top two items on the +stack are equal. It does not set them equal. There are other questions +that you can ask. Enter: + +- 23 198 < . + 23 198 > . + 254 15 > . + +In California, the drinking age for alcohol is 21. You could write a +simple word now to help bartenders. Enter: + +- : DRINK? ( age -- flag , can this person drink? ) + 20 > + ; + + 20 DRINK? . + 21 DRINK? . + 43 DRINK? . + +The word FLAG in the stack diagram above refers to a logical value. + +Forth provides special words for comparing a number to 0. They are +**0=** **0\>** and **0\<** . Using 0\> is faster than calling 0 and \> +separately. Enter: + +- `23 0> . ( print -1 )`\ + `-23 0> . ( print 0 )`\ + `23 0= . ( print 0 )` + +For more complex decisions, you can use the *Boolean* operators **OR** , +**AND** , and **NOT** . OR returns a TRUE if either one or both of the +top two stack items are true. + +- TRUE TRUE OR . + TRUE FALSE OR . + FALSE FALSE OR . + +AND only returns a TRUE if both of them are true. + +- TRUE TRUE AND . + TRUE FALSE AND . + +NOT reverses the value of the flag on the stack.

CR ( print number on top of stack ) + 1- DUP 0< ( loop until we go negative ) + UNTIL + ; + + 16 COUNTDOWN + +This word will count down from N to zero. + +If you know how many times you want a loop to execute, you can use the +**DO\...LOOP** construct. Enter: + +- : SPELL + ." ba" + 4 0 DO + ." na" + LOOP + ; + +This will print \"ba\" followed by four occurrences of \"na\". The +ending value is placed on the stack before the beginning value. Be +careful that you don\'t pass the values in reverse. Forth will go \"the +long way around\" which could take awhile.

This section +concentrates on using strings of characters. You can embed a text string +in your program using S\". Note that you must follow the S\" by one +space. The text string is terminated by an ending \" .Enter: + +- : TEST S" Hello world!" ; + TEST .S + +Note that TEST leaves two numbers on the stack. The first number is the +address of the first character. The second number is the number of +characters in the string. You can print the characters of the string as +follows. + +- TEST DROP \ get rid of number of characters + DUP C@ EMIT \ prints first character, 'H' + CHAR+ DUP C@ EMIT \ prints second character, 'e' + \ and so on + +CHAR+ advances the address to the next character. You can print the +entire string using TYPE. + +- TEST TYPE + TEST 2/ TYPE \ print half of string + +It would be nice if we could simply use a single address to describe a +string and not have to pass the number of characters around. \'C\' does +this by putting a zero at the end of the string to show when it ends. +Forth has a different solution. A text string in Forth consists of a +character count in the first byte, followed immediately by the +characters themselves. This type of character string can be created +using the Forth word C\" , pronounced \'c quote\'. Enter: + +- : T2 C" Greetings Fred" ; + T2 . + +The number that was printed was the address of the start of the string. +It should be a byte that contains the number of characters. Now enter: + +- T2 C@ . + +You should see a 14 printed. Remember that C@ fetches one character/byte +at the address on the stack. You can convert a counted Forth string to +an address and count using COUNT. + +- T2 COUNT .S + TYPE + +The word **COUNT** extracts the number of characters and their starting +address. COUNT will only work with strings of less than 256 characters, +since 255 is the largest number that can be stored in the count byte. +TYPE will, however, work with longer strings since the length is on the +stack. Their stack diagrams follow: + +**`CHAR+ ( address -- address' , add the size of one character )`** + +**`COUNT ( $addr -- addr #bytes , extract string information ) `** + +**`TYPE ( addr #bytes -- , output characters at addr )`** + +The \$addr is the address of a count byte. The dollar sign is often used +to mark words that relate to strings. + +You can easily input a string using the word **ACCEPT**. (You may want +to put these upcoming examples in a file since they are very handy.) The +word **ACCEPT** receives characters from the keyboard and places them at +any specified address. **ACCEPT** takes input characters until a maximum +is reached or an end of line character is entered. **ACCEPT** returns +the number of characters entered. You can write a word for entering +text. Enter: + +- : INPUT$ ( -- $addr ) + PAD 1+ ( leave room for byte count ) + 127 ACCEPT ( recieve a maximum of 127 chars ) + PAD C! ( set byte count ) + PAD ( return address of string ) + ; + + INPUT$ COUNT TYPE + +Enter a string which should then be echoed.

Your cup that says " COUNT TYPE + ." is in the mail!" CR + ; + +**`ACCEPT ( addr maxbytes -- numbytes , input text, save at address ) `** + +You can use your word INPUT\$ to write a word that will read a number +from the keyboard. Enter: + +- : INPUT# ( -- N true | false ) + INPUT$ ( get string ) + NUMBER? ( convert to a string if valid ) + IF DROP TRUE ( get rid of high cell ) + ELSE FALSE + THEN + ; + +This word will return a single-precision number and a TRUE, or it will +just return FALSE. The word **NUMBER?** returns a double precision +number if the input string contains a valid number. Double precision +numbers are 64-bit so we DROP the top 32 bits to get a single-precision +32 bit number. + +## []{#Changing Numeric Base}Changing Numeric Base + +For day-to-day life, the numbering system we use is decimal, or \"base +10.\" That means each digit get multiplied by a power of 10. Thus a +number like 527 is equal to (5\*100 + 2\*10 + 7\*1). The use of 10 for +the numeric base is a completely arbitrary decision. It no doubt has +something to do with the fact that most people have 10 fingers +(including thumbs). The Babylonians used base 60, which is where we got +saddled with the concept of 60 minutes in an hour. Computer hardware +uses base 2, or \"binary\". The computer number \"1101\" is equal to +(1\*8 + 1\*4 + 0\*2 + 1\*1). If you add these up, you get 8+4+1=13 . The +binary number \"10\" is (1\*2 + 0\*1), or 2. Likewise the numeric string +\"10\" in any base N is N. + +Forth makes it very easy to explore different numeric bases because it +can work in any base. Try entering the following: + +- DECIMAL 6 BINARY . + 1 1 + . + 1101 DECIMAL . + +Another useful numeric base is *hexadecimal*. which is base 16. One +problem with bases over 10 is that our normal numbering system only has +digits 0 to 9. For hex numbers we use the letters A to F for the digits +10 to 15. Thus the hex number \"3E7\" is equal to (3\*256 + 14\*16 + +7\*1). Try entering: + +- DECIMAL 12 HEX . \ print C + DECIMAL 12 256 * 7 16 * + 10 + .S + DUP BINARY . + HEX . + +A variable called **BASE** is used to keep track of the current numeric +base. The words **HEX** , **DECIMAL** , and **BINARY** work by changing +this variable. You can change the base to anything you want. Try: + +- 7 BASE ! + 6 1 + . + BASE @ . \ surprise! + +You are now in base 7 . When you fetched and printed the value of BASE, +it said \"10\" because 7, in base 7, is \"10\". + +PForth defines a word called .HEX that prints a number as hexadecimal +regardless of the current base. + +- DECIMAL 14 .HEX + +You could define a word like .HEX for any base. What is needed is a way +to temporarily set the base while a number is printed, then restore it +when we are through. Try the following word: + +- : .BIN ( N -- , print N in Binary ) + BASE @ ( save current base ) + 2 BASE ! ( set to binary ) + SWAP . ( print number ) + BASE ! ( restore base ) + ; + + DECIMAL + 13 .BIN + 13 . + +## []{#Answers to Problems}Answers to Problems + +If your answer doesn\'t exactly match these but it works, don\'t fret. +In Forth, there are usually many ways to the same thing. + +### [Stack Manipulations](#Problems%20-%20Stack) + +- 1) SWAP DUP + 2) ROT DROP + 3) ROT DUP 3 PICK + 4) SWAP OVER 3 PICK + 5) -ROT 2DUP + +### [Arithmetic](#Problems%20-%20Square) + +- (12 * (20 - 17)) ==> 20 17 - 12 * + (1 - (4 * (-18) / 6)) ==> 1 4 -18 * 6 / - + (6 * 13) - (4 * 2 * 7) ==> 6 13 * 4 2 * 7 * - + + : SQUARE ( N -- N*N ) + DUP * + ; + + : DIFF.SQUARES ( A B -- A*A-B*B ) + SWAP SQUARE + SWAP SQUARE - + ; + + : AVERAGE4 ( A B C D -- [A+B+C+D]/4 ) + + + + ( add'em up ) + 4 / + ; + + : HMS>SECONDS ( HOURS MINUTES SECONDS -- TOTAL-SECONDS ) + -ROT SWAP ( -- seconds minutes hours ) + 60 * + ( -- seconds total-minutes ) + 60 * + ( -- seconds ) + ; + +### [Logical Operators](#Problems%20-%20Logical) + +- : LOWERCASE?

Project Overview - -This language is a small, dynamically typed (with optional static type annotations) scripting language. Its syntax is inspired by ML-family languages, focusing on immutability and expression-oriented programming. Key features include: - -* **Functional Core:** Emphasizes anonymous functions, currying, partial application, and **recursive functions**. -* **Pattern Matching:** A powerful `when` expression for control flow, supporting literal, multi-argument, and type-based matching. -* **Robust Error Handling:** A `Result` type for explicit success/failure propagation, inspired by Rust. -* **Simple Syntax:** Designed to be easy to read and write. -* **Recursive Functions:** Full support for self-recursive functions with proper scoping. -* **Mathematical Constants:** Built-in `PI` and `INFINITY` constants for mathematical operations. -* **Immutable Data Structures:** All list and table operations are immutable, ensuring data integrity. - -## 2. Architecture - -The language engine is structured into three main components, following a classic compiler/interpreter design pattern: - -* ### Lexer (or Tokenizer) - `lexer.js` - The lexer is the first phase of processing. It takes the raw source code as a string and breaks it down into a stream of meaningful units called **tokens**. Each token represents a fundamental building block of the language, like keywords, identifiers, operators, numbers, and strings. It also handles whitespace and comments by removing them from the token stream. - -* ### Parser - `parser.js` - The parser takes the stream of tokens generated by the lexer and builds an **Abstract Syntax Tree (AST)**. The AST is a representation of the program's syntactic structure, abstracting away the actual syntax. It organizes the tokens into a hierarchical structure that reflects the grammatical rules of the language, making it easier for the interpreter to understand and execute the code. The parser is responsible for enforcing syntax rules and reporting syntax errors. - -* ### Interpreter - `interpreter.js` - The interpreter is the execution engine of the language. It traverses the AST generated by the parser and evaluates each node, performing the operations defined by the program. It manages the program's state, including variable scopes, function definitions, and type information. The interpreter directly executes the program's logic, handling function calls, control flow, and data manipulation. - -## 3. Extensibility: How to Add New Features - -Extending this language involves modifying one or more of the core architectural components: - -* **Adding New Keywords or Operators:** - * **`lexer.js`** - : Update the `tokenTypes` object with new token types. Add the new keyword/operator to the `keywords` array or the `if` conditions in `nextToken` to recognize and categorize it. - * **`parser.js`** - : If the new token introduces new syntax, you'll need to add new parsing functions or modify existing ones (e.g., `parsePrimary`, `parseExpression`) to create corresponding AST nodes. - * **`interpreter.js`** - : Implement `visit` methods for any new AST node types to define their runtime behavior. - -* **Adding New Data Types:** - * **`lexer.js`** - : Add the new type name to the `tokenTypes` and ensure `nextToken` correctly identifies it as a `TYPE`. - * **`parser.js`** - : Modify `parseTypeDeclaration` and potentially `parsePrimary` or `parsePattern` to create AST nodes for the new type. - * **`interpreter.js`** - : Update `visitVariableDeclaration` and `visitWhenExpression` (for type matching) to handle the new type's runtime representation and type checking. - -* **Adding New Control Flow or Language Constructs:** - * **`lexer.js`** - : Add any new keywords or symbols required for the construct. - * **`parser.js`** - : Implement new parsing functions to build the AST representation of the new construct. This often involves defining new AST node types. - * **`interpreter.js`** - : Implement `visit` methods for the new AST nodes to define their execution logic. - -## 4. Language Features Reference Card - -### Comments - -Single-line comments start with `//`. +# Baba Yaga Programming Language -```baba -// This is a comment -myVar : 10; // This is also a comment -``` - -### Types - -The language supports basic types and a `Result` type. Type declarations are optional but enforced if provided. - -* `Int`: Integer numbers (e.g., `10`, `0`, `-5`). -* `Float`: Floating-point numbers (e.g., `3.14`, `0.5`). -* `String`: Text enclosed in double quotes (e.g., `"hello"`, `"world"`). -* `Result`: A union type representing either a successful outcome (`Ok`) or an error (`Err`). - -### Constants - -The language provides built-in mathematical constants `PI` and `INFINITY`. - -```baba -// Using mathematical constants -circumference : radius -> 2 * PI * radius; -area : radius -> PI * radius * radius; - -result : (circumference 5); -``` - -### Lists - -Lists are ordered collections of values, enclosed in square brackets `[]`. - -```baba -myList : [1, 2, 3, "hello"]; - -// Accessing elements by index (0-based) -firstElement : myList.0; -secondElement : myList.1; -``` - -### Tables - -Tables (or records/objects) are unordered collections of key-value pairs enclosed in curly braces `{}`. Keys are identifiers, and values can be any expression. - -```baba -myTable : { name: "Lucy Snowe", age: 23, isActive: true }; - -// Accessing properties by key -userName : myTable.name; -userAge : myTable.age; -``` - -### Variable and Type Declarations - -Variables are declared using an identifier followed by a colon and their value.

+``` + +### Error Recovery Patterns + +```baba +// Retry pattern +retryOperation : operation maxAttempts -> + attempt : 1; + + tryOperation : currentAttempt -> + when (currentAttempt > maxAttempts) is + true then Err "Max attempts exceeded" + false then when (operation) is + Ok result then Ok result + Err _ then tryOperation (currentAttempt + 1); + + tryOperation attempt; + +// Fallback pattern +withFallback : primaryOp fallbackOp -> + when primaryOp is + Ok result then Ok result + Err _ then fallbackOp; +``` + +## Best Practices + +### 1. Always Use Result Types + +Never assume JavaScript operations will succeed: + +```baba +// Good +result : when (io.callJS "Math.abs" [value]) is + Ok abs then processValue abs + Err msg then handleError msg; + +// Bad - assumes success +abs : io.callJS "Math.abs" [value]; // This returns Result, not number +``` + +### 2. Validate Inputs + +Always validate data before sending to JavaScript: + +```baba +// Good +safeCall : value -> + when (validate.type "Number" value) is + false then Err "Value must be a number" + true then io.callJS "Math.abs" [value]; + +// Bad - no validation +unsafeCall : value -> + io.callJS "Math.abs" [value]; +``` + +### 3. Handle Type Conversions Explicitly + +Be explicit about type conversions: + +```baba +// Good +processJSData : jsData -> + when (io.objectToTable jsData) is + Ok table then processTable table + Err msg then Err ("Conversion failed: " .. msg); + +// Bad - assumes conversion works +processJSData : jsData -> + table : io.objectToTable jsData; + processTable table; +``` + +### 4. Use Composition for Complex Operations + +Break complex JavaScript interactions into smaller, composable functions: + +```baba +// Composed operations +parseAndValidate : jsonStr schema -> + parsed : safeParseJSON jsonStr; + when parsed is + Ok data then validateAgainstSchema data schema + Err msg then Err msg; + +transformAndStringify : data transformer -> + transformed : transformer data; + safeStringifyJSON transformed; +``` + +## Examples + +### Complete JSON Processing Pipeline + +```baba +// Complete JSON processing with error handling +processJSONData : jsonString -> + // Parse JSON + parseResult : io.callJS "JSON.parse" [jsonString]; + + when parseResult is + Err msg then Err ("Parse failed: " .. msg) + Ok jsObj then + // Convert to Baba Yaga table + when (io.objectToTable jsObj) is + Err msg then Err ("Conversion failed: " .. msg) + Ok table then + // Process the data + processedTable : processData table; + + // Convert back to JS object + jsResult : io.tableToObject processedTable; + + // Stringify result + io.callJS "JSON.stringify" [jsResult]; + +// Helper function +processData : table -> + // Add timestamp + withTimestamp : table .. {timestamp: getCurrentTimestamp}; + + // Validate required fields + when (hasRequiredFields withTimestamp) is + false then table .. {error: "Missing required fields"} + true then withTimestamp; + +// Usage +input : "{\"name\": \"Alice\", \"score\": 95}"; +result : processJSONData input; +// Returns: Ok (JSValue "{\"name\":\"Alice\",\"score\":95,\"timestamp\":1640995200000}") +``` + +### Working with JavaScript Arrays + +```baba +// Process JavaScript arrays +processJSArray : jsArrayString -> + // Parse array + arrayResult : io.callJS "JSON.parse" [jsArrayString]; + + when arrayResult is + Err msg then Err msg + Ok jsArray then + // Convert to Baba Yaga list + when (io.jsArrayToList jsArray) is + Err msg then Err msg + Ok babaList then + // Process with Baba Yaga functions + processed : map (x -> x * 2) babaList; + filtered : filter (x -> x > 10) processed; + + // Convert back to JS array + jsResult : io.listToJSArray filtered; + + // Return as JSON + io.callJS "JSON.stringify" [jsResult]; + +// Usage +input : "[1, 2, 3, 4, 5, 6, 7, 8, 9, 10]"; +result : processJSArray input; +// Returns: Ok (JSValue "[4,6,8,10,12,14,16,18,20]") +``` + +This JavaScript interop system provides a safe, controlled way to leverage JavaScript's ecosystem while maintaining Baba Yaga's functional programming principles and explicit error handling. diff --git a/js/baba-yaga/docs/README.md b/js/baba-yaga/docs/README.md new file mode 100644 index 0000000..30f8700 --- /dev/null +++ b/js/baba-yaga/docs/README.md @@ -0,0 +1,82 @@ +# Baba Yaga Documentation + +This directory contains comprehensive documentation for the Baba Yaga functional programming language. + +## Documentation Structure + +### Core Documentation + +- **[00_crash-course.md](./00_crash-course.md)** - Complete language overview for quick reference (ideal for LLMs and quick onboarding) +- **[01_functional.md](./01_functional.md)** - Functional programming concepts, higher-order functions, and function combinators +- **[02_data-structures.md](./02_data-structures.md)** - Lists, tables, and array programming operations +- **[03_pattern-matching.md](./03_pattern-matching.md)** - Pattern matching syntax, guards, and advanced patterns +- **[04_types.md](./04_types.md)** - Optional type system, runtime validation, and type inference +- **[05_recursion-and-composition.md](./05_recursion-and-composition.md)** - Recursive functions, mutual recursion, and function composition +- **[06_error-handling.md](./06_error-handling.md)** - Result types, assertions, validation, and error handling patterns +- **[07_gotchyas.md](./07_gotchyas.md)** - Common syntax pitfalls and strict requirements +- **[08_array-programming.md](./08_array-programming.md)** - Comprehensive guide to array programming operations +- **[09_js-interop.md](./09_js-interop.md)** - JavaScript interoperability and safe JS integration + +## Topic Coverage + +### Language Fundamentals +- **Syntax**: Variables, functions, data types, operators (00, 07) +- **Data Types**: Numbers, strings, booleans, lists, tables (00, 02) +- **Functions**: Anonymous functions, currying, partial application (00, 01) +- **Control Flow**: `when` expressions, pattern matching (00, 03) + +### Advanced Features +- **Pattern Matching**: Literals, wildcards, types, guards, multiple discriminants (03) +- **Type System**: Optional types, runtime validation, function signatures (04) +- **Error Handling**: Result types, assertions, validation patterns (06) +- **Recursion**: Simple, tail, and mutual recursion (05) + +### Functional Programming +- **Higher-Order Functions**: `map`, `filter`, `reduce` (01) +- **Function Combinators**: `flip`, `apply`, `pipe`, `compose` (01) +- **Array Programming**: Indexing, scanning, broadcasting, reshaping (02, 08) +- **Monadic Operations**: `flatMap` and data transformation (01, 02, 08) + +### Standard Library +- **Array Operations**: `scan`, `cumsum`, `at`, `where`, `take`, `drop`, `broadcast`, `zipWith`, `reshape` (02, 08) +- **Math Functions**: Arithmetic, trigonometry, random numbers (00) +- **String Processing**: Manipulation, formatting, validation (00) +- **Utilities**: Sorting, grouping, debugging, validation (00, 06) +- **JavaScript Interop**: Safe JS function calls, property access, type conversion (09) + +## Documentation Principles + +1. **Non-Duplicative**: Each concept is documented in one primary location with cross-references +2. **Comprehensive**: All language features and standard library functions are covered +3. **Hierarchical**: Start with crash course, then dive into specific topics +4. **Practical**: Includes working examples and common patterns +5. **Error-Aware**: Documents error cases and safe usage patterns + +## Reading Path + +### For New Users +1.

that causes it to **skip large portions of input files** and produce incorrect tokens, leading to runtime errors. + +## 📊 **Impact Assessment** + +- **Severity**: Critical - causes complete parsing failures +- **Scope**: Context-dependent - works for simple cases, fails on complex files +- **Test Coverage**: All 210 tests pass (suggests bug is triggered by specific patterns) +- **Workaround**: Use `--legacy` flag to use the working legacy lexer + +## 🔍 **Bug Symptoms** + +### **Observed Behavior:** +1. **Content Skipping**: Lexer jumps from beginning to middle/end of file +2. **Token Mangling**: Produces partial tokens (e.g., "esults" instead of "Results") +3. **Line Number Issues**: First token appears at line 21 instead of line 1 +4. **Variable Name Errors**: Runtime "Undefined

Analysis** + +### **Suspected Root Causes:** + +1. **Regex Pattern Conflicts**: Token patterns may be interfering with each other +2. **Multiline Comment Handling**: `/^\/\/.*$/m` regex may be consuming too much +3. **Pattern Order Issues**: Longer patterns not matching before shorter ones +4. **Position Tracking Bug**: `advance()` function may have off-by-one errors + +### **Key Differences from Legacy:** + +| Aspect | Legacy | Optimized | Issue | +|--------|--------|-----------|--------| +| **Method** | Character-by-character | Regex-based | Regex conflicts | +| **Identifier

if comment regex consumes too much +3. **Position Tracking**: Verify `advance()` function correctness +4. **Error Handling**: Check regex failure recovery + +## 📈 **Performance Impact** + +- **Legacy Lexer**: Reliable, slightly slower character-by-character parsing +- **Optimized Lexer**: When working, ~2-3x faster, but **completely broken** for many cases +- **Net Impact**: Negative due to correctness failures + +## ✅ **Recommended Actions** + +### **Immediate (Done):** +1. ✅ **Revert to legacy lexer by default** for reliability +2. ✅ **Document the bug** for future investigation +3. ✅ **Keep optimized lexer available** with explicit flag + +### **Future Investigation:** +1. **Debug regex pattern interactions** in isolation +2. **Add comprehensive lexer test suite** with problematic
