Rewrote internal JSON parsing to correctly handle whitespace, escaped
quotes, and strict field context extraction. This prevents incorrect
field names or provider names from being added to the model list.
Added `ai_parse_models_from_json` public API to facilitate testing.
Changed `/ai models` default behavior to always fetch fresh models.
Replaced `--refresh` flag with `--cached` to display local cache.
Added comprehensive unit tests covering OpenAI and Perplexity formats,
array format, empty/null JSON, escaped quotes, and whitespace handling.
- Introduce model caching with persistence to preferences
- Add provider default model and custom settings management
- Implement `/ai switch`, `/ai models`, and improve `/ai start`
- Add model name autocomplete for chat commands
- Update command definitions and help text
- Add unit tests for new functionality
Update ai_providers_find() to handle NULL search_str safely by treating it
as an empty string, preventing a segfault in strdup() within autocomplete_complete().
Rename test_ai_providers_find_case_sensitive to test_ai_providers_find_case_insensitive
to reflect the new case-insensitive matching contract. Update all affected tests to
expect cycling behavior (NULL/empty returns first provider) and use auto_gchar for
automatic memory management.
Use `gchar` instead of `char` in ai_providers_find for consistency
Add an AI client module that integrates with OpenAI-compatible API
providers (OpenAI, Perplexity, and custom providers) to provide
AI-assisted responses within the profanity client.
The implementation includes:
- src/ai/ai_client.c/h: Core AI client with provider management,
session handling, and async HTTP request handling via libcurl.
Supports per-provider API keys stored in preferences, reference-
counted sessions, and conversation history tracking.
- src/ui/window.c/window_list.c: New AI window type (ProfAiWin) for
displaying AI conversations, with response streaming and error
display capabilities.
- Command integration: New `/ai` command (cmd_defs.c, cmd_funcs.c)
for creating sessions, sending prompts, and managing providers.
Provider autocomplete support in cmd_ac.c.
- Preferences integration: API keys for providers are persisted in
the preferences system (config/preferences.c).
- Unit tests: 472 lines of comprehensive tests covering provider
management, session lifecycle, JSON escaping, and autocomplete
(tests/unittests/test_ai_client.c).
Architecture decisions:
- Asynchronous design: HTTP requests run on a separate thread to
avoid blocking the main UI loop. Callbacks are invoked on the main
thread via direct function call (profanity uses ncurses, not GLib
main loop).
- Reference counting: Both AIProvider and AISession use ref counting
for safe shared ownership.
- Response size limit: 10MB cap on HTTP responses to prevent OOM.
