# String Escaping and Keybind Spam Fix - COMPLETE

## Task 3: Enhanced `unwrapDollars()` - COMPLETE ✓

All backends now have enhanced string handling with proper escape sequences:

### Backends Updated:
1. **Python** (codegen_py.cpp) - ✓ COMPLETE
2. **JavaScript** (codegen_js.cpp) - ✓ COMPLETE (uses backticks)
3. **C++** (codegen_cpp.cpp) - ✓ COMPLETE
4. **C** (codegen_c.cpp) - ✓ COMPLETE
5. **Go** (codegen_go.cpp) - ✓ COMPLETE
6. **Rust** (codegen_rs.cpp) - ✓ COMPLETE
7. **V** (codegen_v.cpp) - ✓ COMPLETE (uses single quotes)
8. **Java** (codegen_java.cpp) - ✓ COMPLETE
9. **HTML** (codegen_html.cpp) - ✓ COMPLETE
10. **ASM** (codegen_asm.cpp) - ✓ COMPLETE (no quotes, just escapes)

### Features:
- Handles `$...$` strings and converts to proper quotes
- Escapes special characters: `\"`, `\\`, `\n`, `\t`
- Preserves `$` inside strings (e.g., `fn "I have $5"`)
- Each backend uses appropriate quote style:
  - Python, C++, C, Go, Rust, Java, HTML: double quotes `"`
  - JavaScript: backticks `` ` ``
  - V: single quotes `'`
  - ASM: no quotes (raw escaped content)

## Task 4: Remove Keybind Spam - PARTIAL ✓

### Completed:
1. **Python** (codegen_py.cpp) - ✓ COMPLETE
   - Added `usesEventListener()` helper function
   - Conditionally emits keybind imports and EventListener class
   - Only when AST contains EventListener, KeyBinding, or InputStmt nodes

2. **JavaScript** (codegen_js.cpp) - ✓ COMPLETE
   - Added `usesEventListener()` helper function
   - Conditionally emits EventListener class and all KEY_* constants
   - Only when AST contains EventListener, KeyBinding, or InputStmt nodes

### Remaining Backends (Need Same Treatment):
- C++ (codegen_cpp.cpp) - includes keybinds.hpp and event_listener.hpp
- C (codegen_c.cpp) - needs checking
- Go (codegen_go.cpp) - needs checking
- Rust (codegen_rs.cpp) - emits EventListener struct
- V (codegen_v.cpp) - emits EventListener struct
- Java (codegen_java.cpp) - needs checking
- HTML (codegen_html.cpp) - emits EventListener class in script
- ASM (codegen_asm.cpp) - has event listener support

### Test Results:
```bash
# Before fix:
./ac test_strings.ac (Python)
# Output: 30+ lines of keybind imports and EventListener class

# After fix:
./ac test_strings.ac (Python)
# Output: Clean 6-line file with just main() function

# JavaScript also clean after fix
```

## Next Steps:
1. Add `usesEventListener()` helper to remaining backends
2. Wrap event listener emission in conditional for each backend
3. Test each backend to ensure no keybind spam
4. Implement `fn "..."` string parsing (parser change needed)
5. Implement `fn *` multiplication (parser change needed)
6. Implement `fn &` and `fn &&` chaining (parser change needed)
