Phase 2 of tab completion: semantic completion for session IDs.
Features:
- /resume <TAB> lists all available sessions from .g3/sessions/
- /resume abc<TAB> filters to sessions starting with 'abc'
- Gracefully returns empty if .g3/sessions/ doesn't exist
Implementation:
- Added list_sessions() helper method to G3Helper
- Added Case 4 in complete() for /resume command
- Updated module docs to reflect new capability
Tests:
- test_resume_completion_lists_sessions - verifies listing and filtering
- test_resume_completion_graceful_no_panic - verifies no crash without sessions dir
Verifies that tab completion correctly ignores:
- Bare quotes: "<TAB> - no path prefix, no completion
- Quoted non-paths: "hello world<TAB> - not a path, no completion
- Quoted text without path prefix: "foo<TAB> - no completion
Also fixes test placement (moved tests inside mod tests block)
Edge cases now handled:
1. Unclosed quotes: "~/My <TAB> - completes paths inside quotes
2. Backslash escapes: ~/My\ <TAB> - unescapes before completing
3. Closed quotes: "~/My Files/"<TAB> - works correctly
Key changes:
- extract_word() now tracks backslash escapes (prev_was_backslash)
- is_path_prefix() strips leading quotes before checking
- Added strip_quotes() and unescape_path() helper methods
- complete() now:
- Strips quotes and unescapes paths before calling FilenameCompleter
- Re-wraps completions in quotes or escapes as appropriate
- Preserves user's quoting style (double vs single quotes)
- Uses backslash escapes if user was already using them
Tests added:
- test_actual_completion_with_quotes - verifies all three edge cases
Path completion now works for:
- ./<TAB> - current directory
- ../<TAB> - parent directory
- ~/<TAB> - home directory
- /<TAB> (not at start of line) - root directory
Command completion (/<TAB>) only triggers at the start of the line.
If no command matches, falls through to path completion (e.g., /etc).
Quote-aware word extraction handles paths with spaces:
- "~/My Files/<TAB>" works correctly
Added tests for:
- Path prefix detection
- Word extraction with quotes
- Command vs path disambiguation
