-## Current Status -- ✅ **Core Language**: Complete and stable (25/27 tests passing) -- ✅ **Table Pattern Matching**: Fixed and working -- ✅ **When Expressions**: Fixed and working -- ✅ **Computed Table Keys**: Fixed and working (Task 1.1 complete) -- ✅ **Multi-value Pattern Expressions**: Fixed and working (Task 1.2 complete) -- ✅ **Pattern Matching Memory**: Fixed and working (Task 1.3 complete) -- ✅ **Partial Application Support**: Fixed and working (Task 2.3 complete) -- ❌ **2 Remaining Issues**: Test 22 parser issue, Integration Test 02 file reading issue - -## Quick Reference -- **Test Command**: `./bin/baba-yaga tests/22_parser_limitations.txt` -- **Key Files**: `src/parser.c` (parser_parse_when_pattern), `tests/22_parser_limitations.txt` -- **Current Error**: `Parse error: Expected 'is' after test expression` -- **Working Test**: `echo "test_multi_expr : x y -> when (x % 2) (y % 2) is 0 0 then \"both even\";" | ./bin/baba-yaga` - -## Implementation Plan - -### **Phase 1: Core Language Features** ✅ **COMPLETE** -All core language features are now working correctly. - -### **Phase 2: Advanced Features** ✅ **COMPLETE** -All advanced features including partial application are now working. - -### **Phase 3: Final Polish** 🔄 **IN PROGRESS** - -#### **Task 3.1: Test 22 Parser Issue** (Test 22) 🔍 **INVESTIGATED** -**Issue**: `Parse error: Expected 'is' after test expression` -**Current**: Core multi-value pattern functionality works correctly -**Status**: Identified specific parser edge case - needs investigation - -**Investigation Findings**: -- ✅ **Individual functions work**: Multi-value patterns parse and execute correctly when tested individually -- ✅ **Isolated syntax works**: Same syntax works perfectly when tested via `echo` -- ❌ **File-specific issue**: The error only occurs when the complete test file is processed -- 🔍 **Parser edge case**: The issue appears to be in how the parser handles multiple patterns in sequence within a file context -- 📍 **Error location**: Parser fails to recognize the `is` keyword in multi-value pattern context when processing the full file - -**Root Cause Analysis**: -- The parser's `parser_parse_when_pattern` function may have an edge case when processing multiple patterns in sequence -- The error suggests the parser is not correctly transitioning between pattern parsing states -- This is likely a subtle parsing state management issue rather than a fundamental syntax problem - -#### **Task 3.2: Integration Test 02 File Reading** (Integration Test 02) -**Issue**: Segmentation fault when reading file directly (works when piped) -**Current**: Core pattern matching works, but file reading has issue -**Status**: Need to fix file reading mechanism - -## **Recent Achievements** - -### **Task 2.3: Partial Application Support** ✅ **COMPLETE** -- **Issue**: Test 17 failed with partial application and arity errors -- **Solution**: Implemented proper partial application in function call mechanism -- **Implementation**: - - Modified `baba_yaga_function_call` to handle partial application - - Created `stdlib_partial_apply` helper function - - Updated `each` function to support partial application -- **Result**: Test 17 now passes, 25/27 tests passing - -### **Task 1.2: Multi-value Pattern Expressions** ✅ **COMPLETE** -- **Issue**: `when (x % 2) (y % 2) is` not supported -- **Solution**: Enhanced parser to handle expressions in parentheses for multi-parameter patterns -- **Implementation**: Added detection for multi-parameter patterns with expressions -- **Result**: Multi-value pattern expressions now work correctly - -### **Task 1.3: Pattern Matching Memory** ✅ **COMPLETE** -- **Issue**: Segmentation fault in complex pattern matching -- **Solution**: Implemented sequence-to-sequence pattern matching for multi-parameter patterns -- **Implementation**: Added element-by-element comparison logic for multi-parameter patterns -- **Result**: Complex nested pattern matching now works correctly - -## **Next Priority** -**Task 3.1**: Fix Test 22 parser edge case to achieve 26/27 tests passing -**Task 3.2**: Fix Integration Test 02 file reading issue to achieve 27/27 tests passing - -## Technical Notes - -### **Partial Application Implementation** -- **Function Call Mechanism**: Modified `baba_yaga_function_call` to detect insufficient arguments -- **Partial Function Creation**: Creates new function with bound arguments stored in scope -- **Argument Combination**: `stdlib_partial_apply` combines bound and new arguments -- **Scope Management**: Uses temporary scope variables to store partial application data - -### **Pattern Matching Enhancements** -- **Multi-parameter Support**: Handles `when (expr1) (expr2) is` syntax -- **Sequence Comparison**: Element-by-element comparison for multi-value patterns -- **Wildcard Support**: `_` pattern matches any value in multi-parameter contexts - -### **Parser Investigation Results** -- **Multi-value patterns work correctly** in isolation and individual function definitions -- **File processing edge case** identified in `parser_parse_when_pattern` function -- **State management issue** suspected when processing multiple patterns in sequence -- **Error occurs specifically** when the complete test file is processed, not in isolated tests - -### **Memory Management** -- **Reference Counting**: Proper cleanup of function references -- **Scope Cleanup**: Automatic cleanup of temporary scope variables -- **Error Handling**: Graceful handling of memory allocation failures - -## Next Action -**Continue with Task 3.1** (Test 22 Parser Issue) - investigate and fix the parser edge case in `parser_parse_when_pattern` function to achieve 26/27 tests passing. - -## Implementation Guide - -### **For Task 3.1: Test 22 Parser Issue** -1. **Investigate `parser_parse_when_pattern` function**: Look for state management issues when processing multiple patterns -2. **Debug the specific failing case**: Add debug output to understand why the parser fails to recognize `is` keyword -3. **Fix the parser logic**: Update the parser to handle the edge case correctly -4. **Test the fix**: Verify that Test 22 now passes - -### **For Task 3.2: Integration Test 02 File Reading** -1. **Investigate the file reading issue**: Compare direct file reading vs piped input -2. **Identify the root cause**: Find why direct file reading causes segmentation fault -3. **Fix the file reading mechanism**: Update the file reading code to handle the issue -4. **Test the fix**: Verify that Integration Test 02 now passes - -### **For CLI Ergonomics** -1. **Simplify the REPL**: Make it more minimal and interactive -2. **Improve error messages**: Better error reporting and debugging -3. **Add helpful features**: Command history, line editing, etc. \ No newline at end of file |
