It provides a more expressive syntax for writing awk programs while maintaining full compatibility with existing awk code. +Rawk helps to bring some modern developer comforts to awk while maintaining awk's portability and inbuilt goodness. -## Features +## Create a rawk file (`example.rawk`): +```rawk +BEGIN { + print "Hello from rawk!" +} -- **Functional Programming**: Define functions with a clean, modern syntax -- **Portable**: Compiles to standard awk that runs on any implementation -- **Mixed Code**: Seamlessly mix rawk functions with regular awk code -- **Standard Library**: Built-in functional programming utilities -- **Error Handling**: Comprehensive error messages and validation +RAWK { + $greet = (name) -> { + return "Hello, " name "!"; + }; + + $add = (x, y) -> { + return x + y; + }; +} -## Quick Start +{ + print greet("World"); + print "2 + 3 =", add(2, 3); + exit 0; +} +``` -### Installation +A `.awk` file should, generally, be a totally valid `.rawk` file. Just like any valid JavaScript is valid TypeScript, likewise with awk and rawk. -No installation required! Just download `rawk.awk` and you're ready to go. +Rawk introduces a new semantic block to awk, so that you can write special forms within the `RAWK {...}` block. -### Basic Usage +## Compile and run: +```bash +# Compile to awk +awk -f rawk.awk example.rawk > example.awk -1. **Create a rawk program** (`hello.rawk`): -```rawk -$greet = (name) -> "Hello, " name "!"; -$add = (x, y) -> x + y; +# Run the compiled program +echo "test" | awk -f example.awk -BEGIN { - print greet("World") - print "2 + 3 =", add(2, 3) -} +# Or compile and run in one line +echo "test" | awk -f rawk.awk example.rawk | awk -f - ``` -2. **Compile and run**: +## How to run the example: ```bash -awk -f rawk.awk hello.rawk | awk -f - -``` +# Compile the example file +awk -f rawk.awk example.rawk > example_output.awk -3. **Or compile to a file**: -```bash -awk -f rawk.awk hello.rawk > hello.awk -awk -f hello.awk +# Run with sample log data +awk -f example_output.awk sample.log + +# Or run with just a few lines +head -10 sample.log | awk -f example_output.awk + +# Or compile and run without outputting an awk file to disk +awk -f rawk.awk example.rawk | awk -f - sample.log ``` -## Language Syntax +## Syntax ### Function Definitions +All functions go inside an `RAWK { ... }` block. -**Single-line functions**: -```rawk -$add = (x, y) -> x + y; -$greet = (name) -> "Hello, " name; -$square = (x) -> x * x; -``` - -**Multi-line functions**: ```rawk -$calculate_area = (width, height) -> { - area = width * height - return area -}; - -$factorial = (n) -> { - if (n <= 1) { - return 1 - } else { - return n * factorial(n - 1) - } -}; +RAWK { + $function_name = (param1, param2) -> { + return param1 + param2; + }; +} ``` ### Function Calls +Call rawk functions from anywhere in the code, -Functions can be called directly, nested, and recursively: ```rawk -$double = (x) -> x * 2; -$square = (x) -> x * x; -$factorial = (n) -> { - if (n <= 1) return 1 - else return n * factorial(n - 1) -}; - -BEGIN { - result = double(square(5)) # Returns 50 - print result - print factorial(5) # Returns 120 +{ + result = add(5, 3); + print result; } ``` -### Mixed awk/rawk Code +### Mixed Code +Mix and match awk and rawk code, -Regular awk code works seamlessly with rawk functions: ```rawk -BEGIN { print "Starting processing..." } +BEGIN { FS = "," } -$process_line = (line) -> "Processed: " line; +RAWK { + $process = (field) -> { + return "Processed: " field; + }; +} { - if (length($0) > 10) { - print process_line($0) " (long line)" - } else { - print process_line($0) " (short line)" + if ($1 != "") { + print process($1); } } - -END { print "Processing complete." } ``` ## Standard Library +Rawk boasts a rather large standard library. -The following functions are automatically available: - -### Array Utilities -- `keys(array)`: Returns count of keys in array -- `values(array)`: Returns count of values in array -- `get_keys(array, result)`: Populates result array with keys -- `get_values(array, result)`: Populates result array with values - -### Functional Programming (Limited Support) -- `map(func_name, array)`: Maps function over array -- `reduce(func_name, array, initial)`: Reduces array with function -- `pipe(value, func_names...)`: Pipes value through functions - -### Testing Functions -- `assert(condition, message)`: Asserts a condition is true -- `expect_equal(actual, expected, message)`: Asserts actual equals expected -- `expect_true(condition, message)`: Asserts condition is true -- `expect_false(condition, message)`: Asserts condition is false - -### Predicate Functions -**Type Checking:** -- `is_number(value)`: Check if value is a number -- `is_string(value)`: Check if value is a string -- `is_array(value)`: Check if value is an array (limited) -- `is_empty(value)`: Check if value is empty - -**Numeric Predicates:** -- `is_positive(value)`: Check if number is positive -- `is_negative(value)`: Check if number is negative -- `is_zero(value)`: Check if number is zero -- `is_integer(value)`: Check if number is integer -- `is_float(value)`: Check if number is float -- `is_even(value)`: Check if number is even -- `is_odd(value)`: Check if number is odd -- `is_prime(value)`: Check if number is prime -- `is_in_range(value, min, max)`: Check if number is in range - -**Boolean Predicates:** -- `is_boolean(value)`: Check if value is boolean (0 or 1) -- `is_truthy(value)`: Check if value is truthy -- `is_falsy(value)`: Check if value is falsy - -**String Predicates:** -- `is_alpha(value)`: Check if string is alphabetic -- `is_numeric(value)`: Check if string is numeric -- `is_alphanumeric(value)`: Check if string is alphanumeric -- `is_whitespace(value)`: Check if string is whitespace -- `is_uppercase(value)`: Check if string is uppercase -- `is_lowercase(value)`: Check if string is lowercase -- `is_palindrome(value)`: Check if string is palindrome -- `is_length(value, length)`: Check if string/array has specific length - -**Validation Predicates:** -- `is_email(value)`: Basic email validation -- `is_url(value)`: Basic URL validation -- `is_ipv4(value)`: Basic IPv4 validation - -## Examples - -### System Monitoring +### Testing ```rawk -# Process df output to monitor disk usage -$analyze_disk = (filesystem, size, used, avail, percent, mount) -> { - if (percent > 90) { - return "CRITICAL: " filesystem " (" mount ") is " percent "% full!" - } else if (percent > 80) { - return "WARNING: " filesystem " (" mount ") is " percent "% full" - } else { - return "OK: " filesystem " (" mount ") has " avail " blocks free" - } -};

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.

Remove any leftover 'case value of' initialization. - -## Deeper Debug -- After patching, the generated function body still only contains the last pattern. -- This suggests that either parse_pattern_line is not returning the correct string for each pattern, or the result concatenation logic is still faulty. -- Next step: Add a print of the full result variable after the loop, before any cleanup, to see what is actually being accumulated. -- Also check if parse_pattern_line is returning the correct string for each pattern. - -## Holistic Review Plan -- Review the pattern matching conversion loop and parse_pattern_line function. -- Check the initialization and update of the result variable. -- Confirm that each pattern is being appended, not overwritten. -- Review the final assembly and output of the function body. -- Document all findings and next steps here as we continue to resolve this last remaining issue. - -## Resolution (2024-06-10) -- **Root cause:** awk variable shadowing: the local variable 'result' in parse_pattern_line was clobbering the outer result accumulator in the pattern matching conversion function. -- **Fix:** Renamed the local variable to 'pattern_result'. -- **Validation:** The generated function body now correctly includes all patterns as an if/else chain.
