Current State +- The parser is fragile, with overlapping regexes and ad-hoc filters. +- Function definitions are leaking into the output. +- Debug output and legacy logic clutter the codebase. +- Validation is inconsistent and sometimes too strict or too loose. +- Recent attempts at a clean rewrite have revealed issues with global variable shadowing (e.g., `function_count`), which can cause state to be lost between parsing and code generation. + +## 2. What We Know +- **Goal:** Only valid AWK code and generated functions should appear in the output—never rawk function definitions. +- **Best Practice:** Parsing should be stateful: when inside a function definition, skip all lines until the function body ends. +- **Simplicity:** Enforce `{}` for all function bodies. Only parse/collect code outside of function definitions. +- **AWK Global State:** All counters and arrays used for function tracking must be global and never shadowed by local variables or loop indices. + +## 3. Goals +- **Robust, simple parsing:** Only collect code outside of function definitions. +- **Clear validation:** Fail fast and clearly if a function definition is malformed. +- **No rawk function definitions in output:** Only AWK code and generated functions. +- **Maintainable codebase:** No debug output, no ad-hoc filters, no legacy logic. Consider supporting this goal by introducing some dev tooling to help debug. + +## 4. Plan + +### A. Clean Up +- Remove all debug output, catch-alls, and legacy single-line function support from `rawk.awk`. +- Refactor the main block to use a clear state machine: + - If inside a function definition, skip all lines until the function body ends. + - Only collect lines outside of function definitions. +- Audit all global variables (especially counters like `function_count`) to ensure they are never shadowed or re-initialized in any function or loop. + +### B. Document +- Keep this plan up to date as we proceed. +- Document the new parsing and validation approach in the code and README. +- Add a section for common pitfalls (see below). + +### C. Implement +1. **Rewrite the main parsing logic:** + - Use a stateful, brace-counting parser. + - Only collect code outside of function definitions. +2. **Update validation:** + - Only allow function definitions of the form `$name = (args) -> { ... }`. + - Fail fast and clearly on any other form. +3. **Test and validate:** + - Create minimal test files to validate the new parser. + - Ensure no function definitions leak into the output. +4. **Update all tests and examples:** + - Convert all function definitions to the new enforced style. + - Remove any legacy syntax from tests and documentation. + +--- + +## 5. Common Pitfalls +- **Global Variable Shadowing:** Never use global counters (e.g., `function_count`) as local variables or loop indices. Always use unique local names for loops. +- **AWK Arrays:** Arrays are global by default. Always clear or re-initialize as needed. +- **Brace Counting:** Ensure the parser correctly tracks nested braces and only exits function mode when all braces are closed. +- **Whitespace Handling:** Regexes for function headers must be robust to whitespace and formatting variations. + +--- + +## 6. How to Resume +- Start by reviewing this plan and the current state of `rawk_new.awk`. +- Begin with a minimal test file (e.g., `test_clean.rawk`) and ensure the parser correctly collects and generates functions. +- If functions are not being generated, check for global variable shadowing or state loss. +- Once the parser is robust, proceed to update and validate all tests and documentation. + +--- + +## 7. Next Steps +1. Clean up `rawk.awk` (remove debug, catch-alls, legacy logic). +2. Clean up repo, removing superfluous test and 1off files. +3. Audit and fix all global variable usage in the new parser. +4. Implement the new stateful parser. +5. Validate with minimal tests. +6.

Test runner and environment variable handling are robust; DEBUG/DEBUG_SEXPR work as intended. + - Only 6/51 tests pass; 45 fail, including basic, integration, closure, and higher-order function tests. + - Most failures are silent (no assertion errors/output), indicating expressions are not being evaluated or CALLs are mis-emitted. + +- **Recent Fixes and Attempts:** + - Refactored top-level CALL emission logic in the compiler to match idiomatic Scheme/Lisp behavior: + - Now, CALL is only emitted for top-level compound expressions whose first symbol is not a special form (define, let, lambda, if, cond, and, or, not). + - Special forms are handled by the compiler, not as function calls. + - Helper function added to extract the first symbol from a compound expression string. + - Type-tracking logic for top-level CALL emission has been removed for simplicity and robustness. + - This approach is modeled after working reference implementations (e.g., [maryrosecook/littlelisp](https://raw.githubusercontent.com/maryrosecook/littlelisp/refs/heads/master/littlelisp.js)). + +- **Current Symptoms:** + - Many tests still fail, including basic arithmetic, map, closures, and higher-order functions. + - Failures are mostly silent: no assertion errors, no output, suggesting expressions are not being evaluated or results are not printed. + - Some improvement: a few more tests pass compared to previous attempts, but the majority still fail. + +## What Has Been Ruled Out +- The VM and test runner are not the source of the remaining failures. +- S-expression parsing and body handling are robust and not the source of the bug. +- The new CALL emission logic is more correct, but not sufficient to fix all test failures. +- The bug is not due to missing CALLs for assert/display/user-defined function calls at the top level. + +## Next Steps: Plan for Remaining Bugs + +1. **Targeted Debugging of Failing Tests:** + - Focus on a representative failing test (e.g., basic_numeric_operations, closures, or a simple assert). + - Inspect the generated assembly and VM output for these tests to confirm whether CALL is being emitted and executed as expected. + - Check for missing PRINT/DISPLAY or incorrect stack state after CALL. + +2. **Special Form Handling Review:** + - Ensure that all special forms (let, lambda, if, cond, etc.) are handled correctly and do not result in spurious CALLs or missed evaluation. + - Confirm that nested expressions within special forms are compiled and evaluated as expected. + +3. **Test and Iterate:** + - After each fix, re-run the minimal and representative tests to confirm progress. + - Once minimal tests pass, move to more complex closure and higher-order function tests. + +4. **Document Findings:** + - Update this file after each major fix or discovery, so the next debugging session has a clear starting point. + +## Goal (Restated) +- Ensure top-level and nested expression evaluation is correct for all cases, including special forms, closures, and function applications. +- Systematically fix all remaining failing tests by following the above plan. \ No newline at end of file diff --git a/awk/scheme/scheme/bin/compiler.awk b/awk/scheme/scheme/bin/compiler.awk new file mode 100755 index 0000000..11001ab --- /dev/null +++ b/awk/scheme/scheme/bin/compiler.awk @@ -0,0 +1,1339 @@ +#!/usr/bin/awk -f + +# Scheme-to-VM Compiler +# +# This compiler translates Scheme expressions into stack-based VM instructions. +# +# -

+## Overview +A little Scheme interpreter implemented in AWK, composed of a compiler and a stack-based virtual machine. The architecture seeks to be modular, with clear separation of concerns between parsing/compilation and execution. The system has evolved to support higher-order functions, nested function calls, and language-agnostic VM design with Forth as a second target language. + +--- + +## 1. Program Flow: High-Level Pipeline + +1. **Input**: User provides Scheme code (via REPL or file). +2. **Compilation**: The compiler (`bin/compiler.awk`) parses and compiles Scheme code into VM instructions. +3. **Execution**: The VM (`bin/vm.awk`) executes the instructions, managing state, environment, and memory. +4. **Output**: Results are displayed via the `display` function or returned as typed values. + +--- + +## 2. Compiler (`bin/compiler.awk`) + +### 2.1. Lexical Analysis (Lexer) +- **Pattern**: *Lexer/Parser Separation* (classic compiler front-end) +- **Why**: Decouples tokenization from parsing, making the code easier to reason about and extend. +- **How**: The compiler tokenizes input into numbers, symbols, strings, and parentheses, handling whitespace and comments with proper string literal recognition. + +### 2.2. Parsing (Recursive Descent) +- **Pattern**: *Recursive Descent Parser* +- **Why**: Simple, direct mapping from grammar to code; easy to debug and extend for a small language. +- **How**: The parser builds an expression tree from tokens, handling nested expressions, string literals, and validating syntax with proper parenthesis matching and error detection for incomplete expressions. + +### 2.3. Code Generation +- **Pattern**: *Visitor/Dispatcher* (for expression types) +- **Why**: Each expression type (number, variable, list, special form, string) is handled by a dedicated function, improving maintainability. +- **How**: The compiler emits stack-based VM instructions for each expression, handling special forms (define, let, lambda) and function calls with proper argument validation. + +### 2.4. Primitive Function Handling +- **Pattern**: *Strategy Pattern* (for different function types) +- **Why**: Different functions require different compilation strategies - some are built-in primitives, others are standard library functions, and some are user-defined. +- **How**: The compiler uses explicit dispatch in `compile_primitive_call()` to handle arithmetic operations, list operations, string operations, and standard library functions with appropriate argument validation. + +### 2.5. Closure Support +- **Pattern**: *Closure Conversion* (from functional programming) +- **Why**: Enables lexical scoping and first-class functions by capturing the environment at lambda creation. +- **How**: The compiler emits `CAPTURE_ENV` instructions to capture the current environment and create closure objects with unique environment IDs. + +### 2.6. Error Detection +- **Pattern**: *Fail-Fast Error Detection* +- **Why**: Early detection of syntax errors prevents runtime issues and improves debugging. +- **How**: The compiler validates parenthesis matching and detects incomplete expressions during parsing, providing clear error messages. + +--- + +## 3. Virtual Machine (`bin/vm.awk`) + +### 3.1. Stack-Based Execution +- **Pattern**: *Stack Machine* (classic VM design) +- **Why**: Simplicity and direct mapping from compiled instructions to execution; easy to implement in AWK. +- **How**: The VM maintains an evaluation stack for operands and results, executing instructions sequentially with proper stack management and cleanup. + +### 3.2. Typed Value System +- **Pattern**: *Tagged Union* (Algebraic Data Type) +- **Why**: Enables runtime type checking and safe operations on heterogeneous values. +- **How**: All values are tagged (e.g., `N:`, `B:`, `P:`, `F:`, `CLOSURE:`, `STR:`) and checked at runtime with type predicates. + +### 3.3. Environment Model +- **Pattern**: *Environment Chain* (Lexical Scoping) +- **Why**: Supports variable bindings, lexical scope, and closures with proper variable lookup. +- **How**: The VM maintains an environment stack for variable bindings, with special handling for global and closure environments, including environment restoration for closure calls. + +### 3.4. Function and Closure Handling +- **Pattern**: *Direct Function Execution* (no program array modification) +- **Why**: Simplifies call/return logic and avoids mutation of the instruction stream. +- **How**: Functions are stored as code blocks; calls execute code directly, with environment management for parameters and closures, including proper environment capture and restoration. + +### 3.5. Function Dispatch System +- **Pattern**: *Registry Pattern* (for function lookup) +- **Why**: Enables efficient function dispatch and supports function aliasing for user convenience. +- **How**: The VM maintains a `FUNCTIONS` registry mapping function names to implementations, allowing multiple names to point to the same function (e.g., `inc` and `++`). + +### 3.6. Variable Argument Functions +- **Pattern**: *Variadic Function* (for flexible argument handling) +- **Why**: Enables functions like `string-append` to accept any number of arguments, improving usability. +- **How**: Functions like `string_append()` process all arguments on the stack using a loop, maintaining proper argument order and type checking. + +### 3.7. Higher-Order Functions +- **Pattern**: *Function as Data* (first-class functions) +- **Why**: Enables functional programming patterns like `map` and `filter` with user-defined functions, lambdas, and closures. +- **How**: The VM implements `map` and `filter` functions that can accept any function type (built-in, user-defined, lambda, closure) through a nested function call mechanism. + +### 3.8. Nested Function Call System +- **Pattern**: *Context Preservation* (for nested execution) +- **Why**: Enables higher-order functions to call other functions while preserving the calling context. +- **How**: The VM maintains a call stack that saves and restores execution context, allowing functions to be called from within other functions without losing state. + +### 3.9. Output System +- **Pattern**: *Visitor Pattern* (for value display) +- **Why**: Different value types require different display formats, and the display logic should be extensible. +- **How**: The `display_value()` function recursively visits different value types, converting them to readable string representations with proper list formatting. + +### 3.10. Heap and Memory Management +- **Pattern**: *Manual Heap with Reference Counting (partial)* +- **Why**: Enables cons cell allocation and basic memory management for list operations. +- **How**: The VM allocates cons cells on a heap array, with a placeholder for reference counting (not fully implemented). + +### 3.11. State Persistence +- **Pattern**: *State Serialization* +- **Why**: Allows global state and functions to persist across REPL sessions for continuity. +- **How**: The VM serializes global variables and function definitions to files, loading them on startup with proper state restoration. + +--- + +## 4. Standard Library Architecture + +### 4.1. Function Registration +- **Pattern**: *Registry Pattern* (for extensible function library) +- **Why**: Enables easy addition of new standard library functions without modifying core VM logic. +- **How**: Functions are registered in the `FUNCTIONS` table during VM initialization, with dispatch logic in `vm_call_function()`. + +### 4.2. Function Aliasing +- **Pattern**: *Alias Pattern* (for user convenience) +- **Why**: Allows multiple names for the same function, improving usability and providing familiar syntax. +- **How**: Multiple entries in the `FUNCTIONS` table point to the same implementation (e.g., `inc` and `++` both point to `add_one`). + +### 4.3. String Operations +- **Pattern**: *Builder Pattern* (for string construction) +- **Why**: String operations like concatenation need to handle variable numbers of arguments efficiently. +- **How**: Functions like `string_append()` build the result incrementally by processing all arguments on the stack in order. + +### 4.4. Higher-Order Functions +- **Pattern**: *Functional Programming Patterns* +- **Why**: Enables data transformation and filtering with user-defined functions. +- **How**: `map` and `filter` functions accept any function type and execute them in a nested context, supporting complex data processing pipelines. + +--- + +## 5. Language-Agnostic VM Design + +### 5.1. Forth Compiler +- **Pattern**: *Multi-Language Frontend* +- **Why**: Demonstrates the VM's language-agnostic nature and validates the instruction set design. +- **How**: A separate Forth compiler (`scratch/forth/forth.awk`) generates the same VM bytecode, proving that the VM can execute code from different source languages. + +### 5.2. Shared Instruction Set +- **Pattern**: *Universal Bytecode* +- **Why**: Enables multiple languages to target the same VM, reducing implementation complexity. +- **How**: Both Scheme and Forth compilers generate identical VM instructions, allowing seamless execution of mixed-language programs. + +### 5.3. Standard Library Integration +- **Pattern**: *Shared Runtime* +- **Why**: Provides consistent functionality across different source languages. +- **How**: The VM's standard library functions are available to all languages targeting the VM, ensuring consistent behavior. + +--- + +## 6. Testing Architecture + +### 6.1. Comprehensive Test Suite +- **Pattern**: *Layered Testing Strategy* +- **Why**: Ensures correctness across different levels of complexity and use cases. +- **How**: Tests are organized into unit tests (48 tests), integration tests, regression tests, and examples, covering basic operations to complex higher-order function scenarios. + +### 6.2. Test Organization +- **Pattern**: *Test Categories* +- **Why**: Different types of tests serve different purposes in validation. +- **How**: Unit tests focus on individual features, integration tests validate complex interactions, regression tests prevent regressions, and examples demonstrate usage patterns. + +### 6.3. Error Detection Testing +- **Pattern**: *Negative Testing* +- **Why**: Ensures the system properly handles and reports errors. +- **How**: Tests include syntax error detection, type checking, and edge cases to validate error handling behavior. + +--- + +## 7. Extensibility and Maintainability + +### 7.1. Separation of Concerns +- **Pattern**: *Layered Architecture* +- **Why**: Compiler and VM are independent, making it easy to extend the language or change the execution model. +- **How**: Clear interfaces between compilation and execution phases, with well-defined instruction formats. + +### 7.2. Function Extension +- **Pattern**: *Open/Closed Principle* (open for extension, closed for modification) +- **Why**: Adding new functions should not require changes to existing code. +- **How**: New functions are added by registering them in the `FUNCTIONS` table and implementing the corresponding VM function. + +### 7.3. Error Handling +- **Pattern**: *Fail-Fast* (for debugging) +- **Why**: Early error detection helps identify issues quickly during development. +- **How**: Functions validate arguments and types at runtime, throwing descriptive error messages. + +### 7.4. Language Extension +- **Pattern**: *Plugin Architecture* (for new languages) +- **Why**: Enables new languages to target the VM without modifying existing code. +- **How**: New language compilers can be added as separate modules that generate the same VM bytecode. + +--- + +## 8. Notable Limitations and Future Enhancements + +### 8.1. Current Limitations +- **Tail Recursion**: No proper tail call optimization +- **Garbage Collection**: Reference counting is stubbed but not enforced +- **Error Recovery**: Minimal error recovery in REPL +- **Type System**: Basic runtime type checking only +- **Performance**: Limited optimization for complex expressions + +### 8.2. Architectural Patterns for Future Enhancements +- **Continuation-Passing Style**: For proper tail recursion +- **Generational Garbage Collection**: For memory management +- **Exception Handling**: For better error recovery +- **Type Inference**: For compile-time type checking +- **JIT Compilation**: For performance optimization + +--- + +## 9.

Language Agnosticism +The VM is completely indifferent to the source language. It only cares about the bytecode format. + +### 2. Compiler Independence +Different languages can have completely different compilers that all target the same VM. + +### 3. Shared Runtime Benefits +All languages get the same: +- Type system +- Memory management +- Error handling +- Performance characteristics +- Debugging capabilities + +### 4. Extensibility +Adding a new language is as simple as writing a new compiler that generates the right bytecode. + +## Conclusion + +This proves your VM design is successful as a **universal target** for multiple languages. The VM is the common denominator - a pure execution engine that can run bytecode from any language that targets its instruction set. + +This is exactly the kind of flexibility and language-agnostic design that makes a VM architecture powerful! \ No newline at end of file diff --git a/awk/scheme/scheme/scratch/forth/forth.awk b/awk/scheme/scheme/scratch/forth/forth.awk new file mode 100755 index 0000000..3cebac0 --- /dev/null +++ b/awk/scheme/scheme/scratch/forth/forth.awk @@ -0,0 +1,241 @@ +#!/usr/bin/awk -f + +# Forth-to-VM Compiler +# This compiler is meant to validate the VM implementation. +# +# Note: Each line is executed in a separate VM instance, so stack state +# does not persist between lines.
