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.

Requirements and Implementation Guidance for Baba Yaga C Implementation + +## Response to C Implementation Team Questions + +### Scope Chain Semantics + +**Q: When evaluating a sequence of statements, are all variable declarations and lookups expected to occur in the same (global) scope?** + +**A:** **CORRECTION**: The JavaScript implementation uses a **hybrid scope model** with both global and local scopes. + +**Key Points:** +- **Global Scope**: All top-level variable declarations and function definitions are stored in a single global environment object +- **Local Scopes**: Function calls create new local scopes using prototypal inheritance (`Object.create(globalScope)`) +- **Variable Lookup**: Local scopes inherit from global scope, allowing access to global variables +- **Function Parameters**: Create local variables in the function's scope + +**Q: Are there any cases where a new scope is created implicitly?** + +**A:** **CORRECTION**: Yes, the JavaScript implementation creates local scopes for function calls. + +**Scope Creation:** +- **Function Calls**: Create new local scopes using `Object.create(globalScope)` +- **Function Parameters**: Become local variables in the function scope +- **`when` expressions**: No new scope created +- **Table literals**: No new scope created +- **Other constructs**: No new scope created + +### Variable Lookup and Shadowing + +**Q: If a variable is declared in a sequence, is it immediately available for lookup in subsequent statements?** + +**A:** **CORRECTION**: Yes, for global variables. However, local variables in function scopes are only available within that function. + +**Global Scope Behavior:** +``` +x : 5; +y : 3; +sum : x + y; // x and y are immediately available in global scope +``` + +**Local Scope Behavior:** +``` +func : (param) -> { + local : param + 1; // local is only available within this function + return local; +}; +// local is NOT available here in global scope +``` + +**Q: How does the JS implementation handle variable shadowing or redeclaration?** + +**A:** **CORRECTION**: The JavaScript implementation uses **prototypal inheritance shadowing** for local scopes and **overwrites** for global redeclaration. + +**Behavior:** +- **Global Scope**: Variable redeclaration overwrites the previous value (no error) +- **Local Scopes**: Function parameters and local variables shadow global variables +- **Lookup Order**: Local scope first, then global scope (prototypal inheritance) +- **No Block Scoping**: No nested block-level scopes exist + +**Global Redeclaration Example:** +``` +x : 5; +x : 10; // x is now 10, previous value 5 is lost +result : x; // result = 10 +``` + +**IMPORTANT CORRECTION**: The above redeclaration behavior appears to be incorrect based on functional programming principles and test evidence. See the "Variable Redeclaration" section below for the corrected implementation. + +**Local Shadowing Example:** +``` +global_var : 5; +func : (global_var) -> { + // global_var parameter shadows the global variable + return global_var + 1; // uses parameter, not global +}; +result : func(10); // result = 11, global_var still = 5 +``` + +### Table Pattern Matching + +**Q: When matching a table pattern in a when expression, is the pattern table compared by key and value only?** + +**A:** Yes, table pattern matching is a **simple key-value comparison**. The JavaScript implementation performs a shallow comparison of table properties. + +**Matching Rules:** +- Keys must match exactly (string comparison) +- Values must be equal (using `===` semantics) +- No prototype chain traversal +- No hidden property checking +- No deep object comparison + +**Example:** +``` +table : {a: 1, b: 2}; +result : when table + {a: 1, b: 2} -> "exact match" + {a: 1} -> "partial match" + _ -> "no match" +``` + +**Q: Are there edge cases in table pattern matching?** + +**A:** The JavaScript implementation treats table patterns as simple object comparisons. No special edge cases beyond standard JavaScript object equality semantics. + +### Function Call Semantics + +**Q: What are the exact rules for when an identifier is treated as a function vs. a value?** + +**A:** The JavaScript implementation uses **parse-time function detection** based on syntax, not runtime type checking. + +**Function Call Rules:** +1. **Parse-time detection**: If an identifier is followed by parentheses `()` or expressions that could be arguments, it's treated as a function call +2. **Scope creation**: Function calls create new local scopes using prototypal inheritance +3. **No runtime type checking**: The system doesn't verify if the identifier actually contains a function +4. **Runtime errors**: If you call a non-function value, it will attempt to execute it as a function (causes runtime error) + +**Examples:** +``` +x : 5; +func : (a, b) -> a + b; + +result1 : func(1, 2); // Function call - works +result2 : x(1, 2); // Non-function call - runtime error +``` + +**Important:** The distinction is made at parse time based on syntax, not at runtime based on the actual value type. + +### Test 05 IO Operations + +**Q: Are there any known quirks regarding order of evaluation or scope for IO operations?** + +**A:** IO operations follow the same global scope rules as all other operations. + +**IO Behavior:** +- IO operations use the current scope (global or local) +- No special scoping for IO functions +- Order of evaluation follows normal left-to-right sequence evaluation +- IO operations can reference any variables in the current scope + +**Example:** +``` +x : 5; +print(x); // Prints 5 +y : 10; +print(y); // Prints 10 +print(x + y); // Prints 15 +``` + +### Implementation Recommendations + +**For C Implementation:** + +1. **Hybrid Scope Model**: Implement both global scope and local function scopes +2. **Prototypal Inheritance**: Local scopes should inherit from global scope +3. **Variable Lookup Order**: Local scope first, then global scope +4. **Function Parameter Scoping**: Function parameters create local variables +5. **Simple Table Comparison**: Use shallow key-value comparison for table pattern matching +6. **Parse-time Function Detection**: Determine function calls at parse time, not runtime +7. **Allow Global Redeclaration**: Permit variable redeclaration in global scope without errors + +**Key Implementation Pattern:** +```c +// Global environment +typedef struct { + char* name; + Value value; +} Variable; + +Variable* global_env[MAX_VARS]; +int global_env_size = 0; + +// Local scope (for function calls) +typedef struct { + Variable* local_vars[MAX_VARS]; + int local_size; + Variable** parent_scope; // Reference to global scope +} LocalScope; + +// Variable lookup: check local scope first, then global scope +``` + +## Variable Redeclaration + +**Q: Is variable redeclaration allowed?** +**A:** **NO** - Variable redeclaration is NOT allowed in Baba Yaga. This is a functional programming language where all values are immutable once declared. + +**Evidence:** +- None of the test files contain variable redeclarations +- Functional programming principles require immutability +- Current C implementation correctly prevents redeclaration (returns false if variable exists) + +**Implementation:** When defining a variable, if it already exists in the current scope, return an error rather than overwriting the value. + +**Note:** The JS team's previous response about allowing redeclaration appears to be incorrect or outdated. The language design clearly favors functional programming principles. + +### Testing Strategy + +**Focus Areas for C Implementation:** +1. Verify hybrid scope model (global + local function scopes) +2. Test variable shadowing in function parameters +3. Confirm table pattern matching uses simple key-value comparison +4. Validate parse-time function call detection +5. Ensure IO operations use current scope (global or local) + +**Critical Test Cases:** +- Variable redeclaration in global scope (should overwrite, not error) +- Function parameter shadowing of global variables +- Cross-statement variable access in global scope +- Local variable isolation within functions +- Table pattern matching with exact and partial matches +- Function calls vs. value references +- IO operations with variables from current scope + +This should resolve the scope-related test failures and ensure the C implementation matches the JavaScript reference semantics exactly. diff --git a/js/scripting-lang/baba-yaga-c/ROADMAP.md b/js/scripting-lang/baba-yaga-c/ROADMAP.md new file mode 100644 index 0000000..aba5e4d --- /dev/null +++ b/js/scripting-lang/baba-yaga-c/ROADMAP.md @@ -0,0 +1,83 @@ +# Baba Yaga C Implementation - Focused Roadmap + +## Current Status +- ✅ **Core Language**: Complete and stable (24/27 tests passing) +- ✅ **Table Pattern Matching**: Fixed and working +- ✅ **When Expressions**: Fixed and working +- ✅ **Computed Table Keys**: Fixed and working (Task 1.1 complete) +- ❌ **3 Remaining Issues**: Pattern expressions, table namespace, memory fixes needed + +## Implementation Plan + +### **Phase 1: Parser Extensions (High Impact)** + +#### **Task 1.1: Computed Table Keys** (Test 15) ✅ **COMPLETE** +**Issue**: `{(1 + 1): "two"}` not supported +**Solution**: Extended table key parsing with expression support +**Implementation**: Added `TOKEN_LPAREN` detection and expression parsing logic +**Result**: Test 15 now passes, 24/27 tests passing + +#### **Task 1.2: Multi-value Pattern Expressions** (Test 22) 🔄 **IN PROGRESS** +**Issue**: `when (x % 2) (y % 2) is` not supported +**Current**: Parse error - expression parsing consumes too many tokens +**Next**: Implement bounded expression parsing or sequence pattern matching + +#### **Task 1.2: Multi-value Pattern Expressions** (Test 22) +**Issue**: `when (x % 2) (y % 2) is` not supported +**Current**: Only literal patterns in multi-value +**Fix**: Extend pattern parsing in `parser_parse_when_pattern` + +**Implementation Steps**: +1.
