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 outputโnever 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. \ No newline at end of file diff --git a/awk/rawk/scratch/debug_findindex.rawk b/awk/rawk/scratch/debug_findindex.rawk new file mode 100644 index 0000000..eabd13a --- /dev/null +++ b/awk/rawk/scratch/debug_findindex.rawk @@ -0,0 +1,38 @@ +BEGIN { + print "=== Debug findIndex Test ===" +} + +RAWK { + $is_positive_num = (x) -> { + return x > 0;
