-# rawk - A Functional Programming Language for awk
+# rawk
+## Make awk rawk.
 
-**rawk** is a modern, functional-style language dialect that compiles to highly portable, standard `awk`. 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." }
 ```

-### Writing Tests
-
-rawk includes a built-in testing framework with assertion functions:
+## Requirements
 
-```rawk
-$add = (x, y) -> x + y;
-
-BEGIN {
-    # Test basic functionality
-    result = add(2, 3)
-    expect_equal(result, 5, "add(2, 3) should return 5")
-    
-    # Test edge cases
-    result = add(0, 0)
-    expect_equal(result, 0, "add(0, 0) should return 0")
-    
-    # Test boolean conditions
-    expect_true(add(2, 2) == 4, "2 + 2 should equal 4")
-    expect_false(add(2, 2) == 5, "2 + 2 should not equal 5")
-    
-    print "All tests passed!"
-}
-```
-
-## Compilation Process
-
-1. **Parse**: rawk function definitions are parsed using `split` on the `->` symbol
-2. **Generate**: Internal awk functions are generated with unique names (`__lambda_0`, `__lambda_1`, etc.)
-3. **Dispatch**: A dispatch table maps public function names to internal names
-4. **Replace**: Function calls are replaced with internal names during compilation
-5. **Output**: Standard library functions are prepended to the final awk script
-
-## Limitations
-
-- **Standard Library**: `map` and `reduce` functions have limited support
-- **Function Count**: Maximum 10 functions per file for standard library compatibility
-- **Function Names**: Must be valid awk identifiers
-- **Array Returns**: Functions cannot return arrays (use pass-by-reference instead)
-
-## Error Handling
-
-The compiler provides helpful error messages for:
-- Invalid function definition syntax
-- Missing `->` symbols
-- Malformed argument lists
-- Unexpected function definitions in multi-line bodies
-
-## Portability
-
-- **Target**: Standard awk (nawk, BSD awk)
-- **Avoids**: gawk-specific features
-- **Uses**: Only standard awk constructs and functions
-- **Compatibility**: Works on any POSIX-compliant system
-
-## Contributing
-
-1. Add test cases for new features
-2. Ensure compatibility with standard awk
-3. Update documentation for new functionality
-4. Test on multiple awk implementations
+- Any awk implementation (gawk, mawk, nawk, etc.)
+- No additional dependencies, strives to work with any POSIX awk

-# -----------------------------------------------------------------------------
-# rawk.awk - The `rawk` Language Compiler
-#
-# This script translates a `.rawk` source file into standard, portable awk code.
-# It parses special `rawk` syntax, generates standard awk functions, and manages
-# a dispatch table for functional programming features.
-#
-# USAGE:
-#   awk -f rawk.awk my_program.rawk | awk -f -
-#
-# EXAMPLES:
-#   # Compile and run a rawk program
-#   awk -f rawk.awk hello.rawk | awk -f -
-#
-#   # Compile to a file for later use
-#   awk -f rawk.awk hello.rawk > hello.awk
-#   awk -f hello.awk
-#
-# LANGUAGE FEATURES:
-#
-# 1. FUNCTION DEFINITIONS:
-#    Single-line: $name = (args) -> expression;
-#    Multi-line:  $name = (args) -> { ... };
-#
-#    Examples:
-#    $add = (x, y) -> x + y;
-#    $greet = (name) -> "Hello, " name;
-#    $calculate = (width, height) -> {
-#        area = width * height
-#        return area
-#    };
-#
-# 2. FUNCTION CALLS:
-#    Functions can be called directly: add(5, 3)
-#    Functions can be nested: double(square(3))
-#    Functions can call other functions within their bodies
-#
-# 3. STANDARD LIBRARY:
-#    The following functions are automatically available:
-#    - 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
-#    - map(func_name, array): Maps function over array (limited support)
-#    - reduce(func_name, array, initial): Reduces array with function (limited support)
-#    - 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
-#
-# 4. MIXED AWK/RAWK CODE:
-#    Regular awk code can be mixed with rawk functions:
-#    BEGIN { print "Starting..." }
-#    $process = (line) -> "Processed: " line;
-#    { print process($0) }
-#    END { print "Done." }

+# License: Public Domain
+# Lets make awk rawk
+
+# =============================================================================
+# Multi-pass compiler
+# =============================================================================
+# 
+# This compiler transforms rawk code into standard awk and smartly includes only
+# those standard library functions you've actually used. It uses a multi-pass 
+# approach to overcome awk's variable scoping limitations and ensure 
+# deterministic compilation.
 #
 # COMPILATION PROCESS:
-# 1. Parse rawk function definitions and generate internal awk functions
-# 2. Build dispatch table mapping public names to internal names
-# 3. Replace function calls with internal names
-# 4. Generate standard library functions
-# 5. Output final awk script
-#
-# LIMITATIONS:
-# - Standard library map/reduce functions have limited support
-# - Maximum 10 functions per file (for standard library compatibility)
-# - Function names must be valid awk identifiers
-# - Array returns from functions are not supported (use pass-by-reference)
+#   Pass 1: Collect all input lines into memory
+#   Pass 2: Detect and validate RAWK { ... } block structure
+#   Pass 3: Extract function definitions from within RAWK block
+#   Pass 4: Analyze function calls to determine standard library dependencies
+#   Pass 5: Generate final awk code with smart standard library inclusion
 #
-# ERROR HANDLING:
-# - Invalid syntax generates descriptive error messages with context
-# - Missing functions are reported at runtime with helpful suggestions
-# - Argument count mismatches are detected with detailed information
-# - Source line correlation for better debugging
-#
-# PORTABILITY:
-# - Output is compatible with standard awk (nawk, BSD awk)
-# - Avoids gawk-specific features for maximum compatibility
-# - Uses only standard awk constructs and functions
-#
-# -----------------------------------------------------------------------------
-
+# LANGUAGE FEATURES:
+#   - Block-based syntax: RAWK { ... } for function definitions
+#   - Functional programming utilities: map, reduce, filter, etc.
+#   - Smart standard library: only includes functions actually used
+#   - Comprehensive error handling with actionable messages

+# rawk v2.0.0 - Current State Documentation
+
+## 🎯 Project Overview
+
+**rawk** is a functional programming language that compiles to standard AWK. It provides a cleaner, more structured syntax for AWK development while maintaining full compatibility with existing AWK code.
+
+## 🏗️ Architecture
+
+### Multi-Pass Compiler
+The current implementation uses a robust multi-pass approach:
+
+1. **Pass 1**: Collect all source lines into memory
+2. **Pass 2**: Detect and validate RAWK blocks
+3. **Pass 3**: Extract function definitions from RAWK blocks
+4. **Pass 4**: Generate output (standard library + user functions + main script)
+
+### Key Benefits
+- **No variable scoping issues**: Eliminates AWK's variable scoping problems
+- **Predictable parsing**: Each pass has a single responsibility
+- **Easy to extend**: New features can be added as new passes
+- **Robust error handling**: Clear, actionable error messages
+
+## 📝 Language Specification
+
+### Block-Based Structure
+```rawk
+BEGIN {
+    print "Initialization"
+}
+
+RAWK {
+    $add = (x, y) -> {
+        return x + y;
+    };
+    
+    $multiply = (a, b) -> {
+        return a * b;
+    };
+}
+
+{
+    result = add(5, 3);
+    print result;
+}
+```
+
+### Function Definitions
+- **Location**: Only inside `RAWK { ... }` blocks
+- **Syntax**: `$name = (args) -> { ... }` (braces required)
+- **Arguments**: Comma-separated list in parentheses
+- **Body**: Multi-line block with explicit `return` statements
+
+### Function Calls
+- **Location**: Anywhere in regular AWK code
+- **Syntax**: `function_name(arg1, arg2, ...)`
+- **Scope**: Functions are globally available after definition
+
+### Standard Library
+Currently includes basic testing functions:
+- `assert(condition, message)`
+- `expect_equal(actual, expected, message)`
+- `expect_true(condition, message)`
+- `expect_false(condition, message)`
+
+## 🔧 Implementation Details
+
+### File Structure
+```
+rawk/
+├── rawk_block_based.awk    # Main compiler (multi-pass)
+├── rawk.awk                # Original implementation (reference)
+├── scratch/                # Archived experimental versions
+├── tests/                  # Test suite
+├── simple_test.rawk        # Basic test case
+└── example.rawk           # Example usage
+```
+
+### Compilation Process
+```bash
+# Two-stage compilation (recommended)
+awk -f rawk_block_based.awk input.rawk > output.awk
+awk -f output.awk input_data.txt
+
+# One-stage compilation and execution
+awk -f rawk_block_based.awk input.rawk | awk -f - input_data.txt
+```
+
+### Error Handling
+- **Missing RAWK block**: "Error: No RAWK block found"
+- **Nested RAWK blocks**: "Error: Nested or multiple RAWK blocks are not supported"
+- **Unclosed RAWK block**: "Error: RAWK block opened at line X but never closed"
+- **Invalid function syntax**: Detailed error messages with suggestions
+
+## ✅ What's Working
+
+### Core Features
+- ✅ Block-based function definitions
+- ✅ Multi-line function bodies
+- ✅ Function extraction and generation
+- ✅ RAWK block validation
+- ✅ Basic error handling
+- ✅ Standard library generation
+- ✅ Clean output generation
+
+### Test Cases
+- ✅ Simple function definition and call
+- ✅ BEGIN block integration
+- ✅ Main block execution
+- ✅ Function return values
+
+## 🚧 What's Missing
+
+### Smart Standard Library
+- **Current**: Always includes all standard library functions
+- **Goal**: Only include functions actually referenced in the code
+- **Implementation**: Need to track function calls and analyze dependencies
+
+### Enhanced Error Handling
+- **Current**: Basic error messages
+- **Goal**: Comprehensive validation with line numbers and suggestions
+- **Missing**: Function call validation, argument count checking
+
+### Function Call Rewriting
+- **Current**: Function calls are passed through unchanged
+- **Goal**: Rewrite function calls to use internal names (like original rawk.awk)
+- **Benefit**: Better error handling and potential optimization
+
+### Extended Standard Library
+- **Current**: Basic testing functions only
+- **Goal**: Full standard library from original rawk.awk
+- **Includes**: Array utilities, functional programming, predicates, etc.
+
+### Documentation and Examples
+- **Current**: Basic examples
+- **Goal**: Comprehensive documentation and test suite
+- **Missing**: Migration guide, best practices, real-world examples
+
+## 🎯 Next Steps Plan
+
+### Phase 1: Core Improvements (Immediate)
+1. **Function call analysis**: Track which functions are actually used
+2. **Smart standard library**: Only include referenced functions
+3. **Function call rewriting**: Use internal names for better error handling
+4. **Enhanced validation**: Check function calls exist, argument counts match
+
+### Phase 2: Standard Library (Short-term)
+1. **Port full standard library**: Array utilities, functional programming, predicates
+2. **Smart inclusion**: Only include functions that are actually used
+3. **Documentation**: Document all available standard library functions
+
+### Phase 3: Developer Experience (Medium-term)
+1. **Better error messages**: Line numbers, context, suggestions
+2. **Warning system**: Non-fatal issues that should be addressed
+3. **Debug mode**: Verbose output for troubleshooting
+4. **Test suite**: Comprehensive tests for all features
+
+### Phase 4: Advanced Features (Long-term)
+1. **Import system**: Include other rawk files
+2. **Type checking**: Basic type validation
+3. **Optimization**: Code optimization passes
+4. **IDE support**: Language server, syntax highlighting
+
+## 🔍 Technical Decisions
+
+### Why Multi-Pass?
+- **Problem**: AWK variable scoping issues made single-pass parsing unreliable
+- **Solution**: Multi-pass eliminates state management complexity
+- **Benefit**: More robust, easier to debug and extend
+
+### Why Block-Based?
+- **Problem**: Original syntax was ambiguous and hard to parse
+- **Solution**: Explicit blocks make parsing deterministic
+- **Benefit**: Clearer code structure, better error messages
+
+### Why Braces Required?
+- **Problem**: Optional braces made parsing complex
+- **Solution**: Always require braces for function definitions
+- **Benefit**: Simpler parsing, clearer code, fewer edge cases
+
+## 📊 Success Metrics
+
+### Current Status
+- ✅ **Compilation**: Works correctly for basic cases
+- ✅ **Function extraction**: Properly extracts and generates functions
+- ✅ **Error handling**: Basic validation working
+- ✅ **Output quality**: Clean, readable AWK code
+
+### Target Metrics
+- **Test coverage**: 90%+ of language features tested
+- **Error messages**: 100% actionable with line numbers
+- **Performance**: Compilation time < 100ms for typical files
+- **Compatibility**: 100% compatible with existing AWK code
+
+## 🎉 Conclusion
+
+The multi-pass block-based approach has successfully solved the core technical challenges. The implementation is now robust, maintainable, and ready for enhancement. The foundation is solid for building out the full feature set.
+
+**Next immediate step**: Implement function call analysis and smart standard library inclusion.

+# Rawk Compiler Rewrite Plan
+
+## 1. 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. Update all tests and documentation.

+# Version: 
+RAWK_VERSION = "0.0.1"
+
+# Lets help awk rawk
+#
+# This script translates a `.rawk` source file into standard, portable awk code.
+# It uses a two-stage compilation approach for robustness and simplicity.
+#
+# This script is implemented in awk, and should work with any POSIX awk.
+#
+# USAGE:
+#   # Two-stage compilation (recommended)
+#   awk -f rawk.awk my_program.rawk > my_program.awk
+#   awk -f my_program.awk
+#
+#   # One-step compilation and execution
+#   awk -f rawk.awk my_program.rawk | awk -f -
+#
+# EXAMPLES:
+#   # Basic usage - compile and run
+#   awk -f rawk.awk hello.rawk | awk -f -
+#
+#   # Compile to rawk to an awk file for later use
+#   awk -f rawk.awk hello.rawk > hello.awk
+#   awk -f hello.awk
+#
+#   # Process input data
+#   awk -f rawk.awk processor.rawk | awk -f - input.txt
+#
+# COMPILATION PROCESS:
+#   1. Parse rawk syntax and validate
+#   2. Generate standard AWK code
+#   3. Output generated code to stdout
+#   4. Output errors/warnings to stderr
+#   5. Exit with appropriate code (0=success, 1=error)
+#
+# -----------------------------------------------------------------------------
+# LANGUAGE FEATURES
+# -----------------------------------------------------------------------------
+
+# 1. FUNCTION DEFINITIONS:
+#    Single-line: $name = (args) -> expression;
+#    Multi-line:  $name = (args) -> { ... };
+#
+#    SYNTAX RULES:
+#    - Each function definition must be on its own line
+#    - No code allowed after function definitions on the same line
+#    - Single-line functions must end with semicolon
+#    - Multi-line functions must not end with semicolon
+#
+#    Examples:
+#    $add = (x, y) -> x + y;
+#    $greet = (name) -> "Hello, " name;
+#    $calculate = (width, height) -> {
+#        area = width * height
+#        return area
+#    };
+#
+#    ❌ Invalid (multiple functions on one line):
+#    $add = (x, y) -> x + y; $multiply = (a, b) -> a * b;
+#
+#    ❌ Invalid (code after function):
+#    $add = (x, y) -> x + y; print "hello";
+#
+#    ❌ Invalid (missing semicolon):
+#    $add = (x, y) -> x + y
+#
+#    ❌ Invalid (extra semicolon):
+#    $calculate = (w, h) -> { return w * h };
+#
+# 2. FUNCTION CALLS:
+#    Functions can be called directly: add(5, 3)
+#    Functions can be nested: double(square(3))
+#    Functions can call other functions within their bodies
+#
+# 3. STANDARD LIBRARY:
+#
+#    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:
+#    - map(func_name, array, result): Apply function to each element of array
+#    - reduce(func_name, array, initial): Reduce array using function (left fold)
+#    - pipe(value, func_name): Pipe value through a single function
+#    - pipe_multi(value, func_names): Pipe value through multiple functions
+#    - dispatch_call(func_name, arg1, arg2, ...): Dynamic function dispatch
+#
+#    ENHANCED ARRAY UTILITIES:
+#    - filter(predicate_func, array, result): Filter array elements based on predicate
+#    - find(predicate_func, array): Find first element that matches predicate
+#    - findIndex(predicate_func, array): Find index of first element that matches predicate
+#    - flatMap(func_name, array, result): Apply function to each element and flatten result
+#    - take(count, array, result): Take first n elements from array
+#    - drop(count, array, result): Drop first n elements from array
+#
+#    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:
+#    - is_number(value), is_string(value), is_array(value)
+#    - is_positive(value), is_negative(value), is_zero(value)
+#    - is_integer(value), is_float(value), is_boolean(value)
+#    - is_even(value), is_odd(value), is_prime(value)
+#    - is_whitespace(value), is_uppercase(value), is_lowercase(value)
+#    - is_email(value), is_url(value), is_ipv4(value), is_ipv6(value)
+#    - is_uuid(value), is_hex(value), is_csv(value), is_tsv(value)
+#    - is_palindrome(value), is_length(value, target_length)
+#    - http_is_redirect(status), http_is_client_error(status), http_is_server_error(status)
+#    - http_is_get(method), http_is_post(method), http_is_safe_method(method), http_is_mutating_method(method)
+#    - url_is_static_file(url), url_has_query_params(url), url_is_root_path(url)
+#    - user_agent_is_mobile(user_agent), user_agent_is_desktop(user_agent), user_agent_is_browser(user_agent)
+#    - ip_is_local(ip), ip_is_public(ip), ip_is_ipv4(ip), ip_is_ipv6(ip)
+#
+# 4. MIXED AWK/RAWK CODE:
+#    Regular awk code can be mixed with rawk functions:
+#    BEGIN { print "Starting..." }
+#    $process = (line) -> "Processed: " line;
+#    { print process($0) }
+#    END { print "Done." }
+#
+# -----------------------------------------------------------------------------
+# ARCHITECTURE AND TECHNICAL MISCELLANY
+# -----------------------------------------------------------------------------
+
+# 1. Parse: Extract rawk function definitions using `->` symbol
+# 2. Generate: Create internal awk functions with unique names (`__lambda_0`, etc.)
+# 3. Dispatch: Build dispatch table mapping public names to internal names
+# 4. Replace: Replace function calls with internal names in source code
+# 5. Output: Generate final awk script with standard library and user code
+#
+# GENERATED CODE STRUCTURE:
+# - Standard library functions (predicates, utilities, testing)
+# - Dispatch table (BEGIN block with RAWK_DISPATCH array)
+# - Internal function definitions (__lambda_0, __lambda_1, etc.)
+# - Main script body (user code with function calls replaced)
+#
+# LIMITATIONS:
+# - Function names must be valid awk identifiers
+# - Array returns from functions are not supported (use pass-by-reference)
+# - Array iteration order is not guaranteed (AWK limitation)
+# - Dynamic dispatch limited to functions defined at compile time
+# - Maximum 5 arguments per function (dispatch table limitation)
+#
+# ERROR HANDLING:
+# - Invalid syntax generates descriptive error messages with context
+# - Missing functions are reported at runtime with helpful suggestions
+# - Argument count mismatches are detected with detailed information
+# - Source line correlation for better debugging
+#
+# PORTABILITY:
+# - Output is compatible with standard awk (nawk, BSD awk)
+# - Avoids gawk-specific features
+# - Uses only standard awk constructs and functions
+#

-# Pattern Matching Debugging Context (rawk)
-
-## Current State
-- Pattern matching functions are parsed and detected correctly.
-- Each pattern line is processed, but only the last pattern is present in the generated function body.
-- Debug output shows that the result variable is being overwritten instead of concatenated.
-- The parse_pattern_line function returns a string like 'if (...) { return ... }', and the main loop is supposed to append each to the result.
-- However, the result variable is not accumulating all patterns as expected.
-
-## Root Cause Analysis
-- The result variable is being overwritten instead of appended to in the pattern matching conversion loop.
-- This is likely due to a misplaced assignment or a logic error in the loop or in parse_pattern_line.
-- The cleanup logic previously removed concatenation, but even after removing it, the result is still not correct.
-- Debug output shows that after each pattern, result only contains the most recent pattern.
-
-## Next Steps
-1. Double-check that result is only initialized once before the loop and only appended to inside the loop.
-2. Add debug prints for pattern_code and result before and after the concatenation in the loop.
-3. Check the final assembly of the function body after the loop.
-4. If the logic is correct, but the output is still wrong, check how the function body is constructed and printed after the loop.
-5. Once fixed, remove debug output and document the fix in this file.
-
-## Findings
-- Debug output confirms that each new pattern overwrites the result instead of appending to it.
-- The result variable was initialized with a string (e.g., 'case value of\n'), and each new pattern was not being appended to the accumulating result.
-- The correct approach is to initialize result as an empty string and append each pattern's code to it.
-- Plan: Patch the code so result is initialized as an empty string and each pattern is appended, not overwritten. 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. The pattern matching test suite passes.
