+# rawk v2.0.0 - Current State Documentation
+
+## ๐ŸŽฏ 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.
+
+## ๐Ÿ—๏ธ 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
+
+## ๐Ÿ“ 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)`
+
+## ๐Ÿ”ง Implementation Details
+
+### File Structure
+```
+rawk/
+โ”œโ”€โ”€ rawk_block_based.awk    # Main compiler (multi-pass)
+โ”œโ”€โ”€ rawk.awk                # Original implementation (reference)
+โ”œโ”€โ”€ scratch/                # Archived experimental versions
+โ”œโ”€โ”€ tests/                  # Test suite
+โ”œโ”€โ”€ simple_test.rawk        # Basic test case
+โ””โ”€โ”€ 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
+
+## โœ… What's Working
+
+### Core Features
+- โœ… Block-based function definitions
+- โœ… Multi-line function bodies
+- โœ… Function extraction and generation
+- โœ… RAWK block validation
+- โœ… Basic error handling
+- โœ… Standard library generation
+- โœ… Clean output generation
+
+### Test Cases
+- โœ… Simple function definition and call
+- โœ… BEGIN block integration
+- โœ… Main block execution
+- โœ… Function return values
+
+## ๐Ÿšง 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
+
+## ๐ŸŽฏ 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
+
+## ๐Ÿ” 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
+
+## ๐Ÿ“Š Success Metrics
+
+### Current Status
+- โœ… **Compilation**: Works correctly for basic cases
+- โœ… **Function extraction**: Properly extracts and generates functions
+- โœ… **Error handling**: Basic validation working
+- โœ… **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
+
+## ๐ŸŽ‰ 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.

+
+## ๐ŸŽฏ Ready for Phase 2
+
+The foundation is solid for Phase 2 improvements:
+
+### Phase 2 Priorities
+1. **Fix functional programming utilities**: Resolve `findIndex`, `take`, `drop` issues
+2. **Enhanced dependency analysis**: Better tracking of function dependencies
+3. **Improved error messages**: Line numbers, context, suggestions
+4. **Performance optimization**: Faster compilation and execution
+5. **Extended test suite**: More comprehensive coverage
+
+### Technical Debt
+- Some array utility functions need implementation fixes
+- Dispatch mechanism could be simplified
+- Dependency analysis could be more sophisticated
+
+## ๐ŸŽ‰ Conclusion
+
+**Phase 1 is a success!** We've successfully:
+
+1. โœ… **Implemented the core vision**: Block-based syntax with smart standard library
+2. โœ… **Solved the main problem**: Variable scoping issues through multi-pass approach
+3. โœ… **Delivered key features**: Function call analysis, smart standard library inclusion
+4. โœ… **Maintained compatibility**: Full standard library from original implementation
+5. โœ… **Created solid foundation**: Robust architecture ready for Phase 2 enhancements
+
+The rawk v2.0.0 compiler is now **production-ready** for basic use cases and provides a solid foundation for future enhancements. The smart standard library feature alone provides significant value by reducing output size and improving maintainability.
+
+**Next step**: Proceed to Phase 2 to address the remaining functional programming issues and enhance the overall developer experience.

+# 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 outputโ€”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.

+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
+#    };
+#
+#    โŒ Invalid (multiple functions on one line):
+#    $add = (x, y) -> x + y; $multiply = (a, b) -> a * b;
+#
+#    โŒ Invalid (code after function):
+#    $add = (x, y) -> x + y; print "hello";
+#
+#    โŒ Invalid (missing semicolon):
+#    $add = (x, y) -> x + y
+#
+#    โŒ 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

+
+These data files are designed to test various scenarios:
+
+1. **Normal operation**: Most data represents typical, valid cases
+2. **Edge cases**: Some data includes boundary conditions (90% disk usage, high CPU processes)
+3. **Error conditions**: Log files include error responses and system issues
+4. **Data validation**: CSV includes various data types for validation testing
+
+## Customization
+
+You can modify these files to test different scenarios:
+- Add more system data for different monitoring scenarios
+- Include different log formats for additional parsing tests
+- Modify CSV data to test different validation rules
+- Create new data files for specific use cases

+awk -f ../../rawk.awk test_data_processing.rawk | awk -f -
+```
+
+### `test_mixed.rawk` - Mixed awk/rawk Code
+Demonstrates mixing rawk functions with regular awk code:
+- Line-by-line processing
+- Integration with awk patterns
+- Combined functionality
+
+**Run with:**
+```bash
+awk -f ../../rawk.awk test_mixed.rawk | awk -f - ../data/test_input.txt
+```
+
+## Use Cases
+
+These examples demonstrate rawk's practical applications:
+
+### System Administration
+- Monitor disk usage and alert on thresholds
+- Track process resource consumption
+- Analyze file system contents
+
+### Web Server Management
+- Parse and analyze web server logs
+- Monitor error rates and traffic patterns
+- Identify problematic requests
+
+### Data Analysis
+- Process CSV files with validation
+- Generate business intelligence reports
+- Analyze employee or customer data
+
+### Log Analysis
+- Parse various log formats
+- Identify system issues
+- Generate operational reports
+
+## Data Files
+
+The examples use sample data files in the `../data/` directory:
+- `test_data.txt`: Simulated system command outputs
+- `test_logs.txt`: Sample Apache and syslog entries
+- `test_employees.csv`: Sample employee data
+- `test_input.txt`: Simple input data for mixed tests

+# Standard Library Tests
+
+This directory contains tests for the built-in standard library functions.
+
+## Test Files
+
+### `test_stdlib_simple.rawk` - Standard Library Functions
+Tests the built-in standard library functions:
+- **Array utilities**: `keys()`, `values()`, `get_keys()`, `get_values()`
+- **Testing functions**: `assert()`, `expect_equal()`, `expect_true()`, `expect_false()`
+- **Functional programming**: `map()`, `reduce()`, `pipe()` (limited support)
+
+**Features:**
+- Direct function calls (these work reliably)
+- Array operations with proper error handling
+- Boolean assertions for testing
+- Basic functional programming utilities
+
+**Run with:**
+```bash
+awk -f ../../rawk.awk test_stdlib_simple.rawk | awk -f -
+```
+
+**Sample Output:**
+```
+โœ“ double(5) = 10
+โœ“ square(4) = 16
+โœ“ add(3, 7) = 10
+๐ŸŽ‰ All basic function tests passed!
+```
+
+## Standard Library Functions
+
+### 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
+
+### 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
+
+### 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
+
+### Predicate Functions (25+ functions)
+**Type Checking:** `is_number()`, `is_string()`, `is_array()`, `is_empty()`
+**Numeric:** `is_positive()`, `is_negative()`, `is_zero()`, `is_integer()`, `is_float()`, `is_even()`, `is_odd()`, `is_prime()`, `is_in_range()`
+**Boolean:** `is_boolean()`, `is_truthy()`, `is_falsy()`
+**String:** `is_alpha()`, `is_numeric()`, `is_alphanumeric()`, `is_whitespace()`, `is_uppercase()`, `is_lowercase()`, `is_palindrome()`, `is_length()`
+**Validation:** `is_email()`, `is_url()`, `is_ipv4()`
+
+## Limitations
+
+The standard library functions have some limitations due to awk's constraints:
+
+1. **Indirect Function Calls**: Standard awk doesn't support `@func` syntax, so some functional programming features are limited
+2. **Array Returns**: Functions cannot return arrays directly (use pass-by-reference)
+3. **String-based Dispatch**: The `map` and `reduce` functions work with string function names but have limited support
+
+## Usage Examples
+
+### Array Operations
+```rawk
+data["a"] = 1
+data["b"] = 2
+data["c"] = 3
+
+key_count = keys(data)  # Returns 3
+get_keys(data, key_array)  # Populates key_array with keys
+```
+
+### Testing
+```rawk
+result = add(2, 3)
+expect_equal(result, 5, "add(2, 3) should return 5")
+expect_true(result > 0, "result should be positive")
+```
+
+### Functional Programming
+```rawk
+numbers[1] = 1; numbers[2] = 2; numbers[3] = 3
+doubled = map("double", numbers)  # Limited support
+```
