Summary

Bug fix release resolving statusLine command overwrite issue during moai-adk update.

Key Fix:

• StatusLine Update: Fixed _update_statusline_command() incorrectly replacing template-substituted statusLine commands
• Impact: StatusLine now consistently includes PATH augmentation, ensuring reliable moai-adk statusline execution
• Scope: Template variable detection and command generation logic

Breaking Changes

None. This is a backward-compatible bug fix.

Fixed

StatusLine Template Substitution Overwrite

• fix: Resolve statusLine template substitution overwrite issue (2afba5d7)
  • Issue: _update_statusline_command() replaced valid template-substituted commands
  • Root cause: Detection logic only accepted ${SHELL} literal, not actual shell paths like /bin/zsh -l -c
  • Fix: Updated detection to accept both ${SHELL} variable and login shell indicator (-l -c)
  • Enhancement: Use build_hook_context() for command generation (same as hooks)
  • Consistency: StatusLine now uses identical format to hooks (includes _PATH_AUGMENT)
  • Files modified:
    • update.py: Updated _update_statusline_command() detection and generation logic
  • Impact: StatusLine commands now match hook format with proper PATH augmentation

Summary

Critical bug fix release resolving JSON parsing failure during moai-adk update on macOS, Linux, and WSL systems.

Key Fix:

• Template Sync: Fixed JSON parsing error when HOOK_SHELL_PREFIX contains shell syntax with quotes
• Impact: All users on macOS/Linux/WSL can now run moai update successfully
• Scope: Template variable substitution system

Breaking Changes

None. This is a backward-compatible bug fix.

Fixed

Template Sync JSON Parsing Error

• fix: Resolve JSON parsing error in template sync (058a9e46)
  • Issue: moai-adk update failed with Expecting ',' delimiter: line 9 column 55 error
  • Root cause: Unescaped quotes in _PATH_AUGMENT (export PATH="$HOME/...") broke JSON when substituted into settings.json
  • Fix: Removed unnecessary quotes from _PATH_AUGMENT (PATH values have no spaces)
  • Enhancement: Added json_safe parameter to _substitute_variables() for JSON-aware escaping using json.dumps()
  • WSL support: Handles _WSL_PATH_NORMALIZE with quotes correctly
  • Files modified:
    • hook_context.py: Simplified _PATH_AUGMENT from 'export PATH="$HOME/..."' to "export PATH=$HOME/..."
    • processor.py: Added JSON escaping with json.dumps()[1:-1] when json_safe=True
    • update.py: Applied JSON-safe escaping to .json files
  • Testing: 80/80 unit tests passing, verified with actual HOOK_SHELL_PREFIX values
  • Impact: Template sync now works correctly on all platforms (macOS/Linux/WSL)
