The generic `/ai <subcommand>` tab-completion was nested inside conditional
blocks that prevented it from firing in common cases — for example,
`/ai<tab>` or `/ai <tab>` would never match subcommands because the
`autocomplete_param_with_ac()` call was guarded by argument count checks
and nested inside the explicit handler branches.
Move the fallback subcommand autocomplete to execute unconditionally after
all explicit handler branches, ensuring `/ai <tab>` always lists available
subcommands regardless of argument count or which subcommand was typed.
Also move the `/ai set` subcommand fallback outside the inner else-block
so it runs whenever args[0] is "set", not only when num_args >= 2.
Use g_strjoinv to join all arguments from args[1] onwards into a
single prompt string. Previously only args[1] was used, truncating
multi-word prompts like '/ai correct hello world' to just 'hello'
Use auto_gchar temporary for g_strndup result in cmd_ai_start to
prevent memory leak. Fix const-cast warning by using a proper
non-const temporary variable.
Remove ai_provider_ref() from ai_list_providers() so the returned
providers do not need to be unref'd by the caller. This matches the
header docstring which states "caller must not free the list or
providers". Also update all callers (cmd_ai_providers, tests) to
remove redundant ai_provider_unref() calls.
ai_get_provider_key() already returns a freshly g_strdup'd copy of
the API key. The outer g_strdup in ai_session_create() created an
unnecessary second copy, leaking the original pointer.
Remove the log_debug line in ai_client.c that leaked the first 10
characters of the API key into logs. This is also contained a memory leak (g_strndup
return value was never freed).
API keys set via /ai set token were only stored in memory and lost
on client restart. prefs_ai_set_token() and prefs_ai_remove_token()
mutated the in-memory prefs but never called _save_prefs(), unlike
other preference setters in the same file.
Both functions now call _save_prefs() after mutating the keyfile,
ensuring API keys persist across client restarts as advertised.
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.
Per XEP-0030 section 3.1: 'if an entity has no associated items,
it MUST return an empty <query/> element.'
The client should display 'No service discovery items for X' when
receiving an empty result, not silently ignore it.
Previous version introduced in commit f28655c5c (2016-05-08) which added an early
return when child == NULL, preventing the message from being shown.
The /connect command can take: account + server <s> + port <p> + tls <t> + auth <a>
which totals 9 arguments, not 7. This fixes argument parsing for full command usage.
- Track unread message indicators and paging state in the window component
- Clear and restore unread markers correctly when navigating between conversations
- Suppress buffer updates and message printing while viewing history to prevent
unwanted scroll jumps and viewport lock
Also includes minor code-style, whitespace, and comment cleanups as well as
updated documentation for metrics and buffer handling.
Add debug output tracking connection lifecycle.
- Track disconnects and reconnects
- Record session login, logout, and reconnection attempts
- Use [CONNDBG] tag for easy log filtering
Add prof_get_current_window API to retrieve the title of the currently active window, matching the titlebar display.
The feature is especially useful to track currently used plugin window.
Remove autodisable logic (prefs_set_autoping(0)) and early return in autoping
to treat intermittent false negatives from connection_supports(XMPP_FEATURE_PING).
Add one-time error display with debug features print for monitoring; warn on first failing
check without aborting to maintain functionality while investigating root cause.
Prior commit (6ad8a190) did not properly handle overflow by long (9000 lines) message,
to address this issue, multiple changes were made:
- Add lines recalculation on win_redraw
- Move `prof_buff_t` struct to header file so its lines could be externally changed
- Call win_redraw once overflow is detected: it allows to recalculate sizes in lines and apply changes to the buffer
Refactor buffer trimming logic to use dynamic line counts (_lines per entry)
against PAD_SIZE (10k) instead of fixed entry count (MAX_BUFFER_SIZE=200). This
prevents premature cleanups for short messages, reduces scrolling disruptions
during history loads, and scales better with rendered content size.
Delete oldest/newest entry from opposite end only when total lines approach
ncurses pad limit, minimizing unnecessary deletions.
Simplify overflow warning log by removing unused MAX_BUFFER_SIZE reference.
Update buffer.c header for improved DX:
- Add detailed module overview explaining role (in-memory UI buffer vs. DB
persistence), key features (trimming, metadata), and integration (ncurses).
- Shorten copyright/license boilerplate to concise pointer (LICENSE ref).
- Add fork notice; preserve original copyrights per GPLv3.
Partially addresses #36 (stuck scroll mitigation via fewer cleanups)

`memchr()` requires the complete memory that shall be searched to be
accessible. Using `strchr()` could work for shorter strings, but we only
want to search in the first 4 chars.
Instead of somehow working around those limitations, simply search manually
in the first 4 bytes.

Implement /force-encryption command to configure forced encryption
settings with on|off and policy resend-to-confirm|block options.
The changes enhance user experience by clarifying encryption requirements
and providing actionable commands. Users can now press Enter again to
confirm unencrypted messages in resend-to-confirm mode.
The synchronous `get_message_from_editor` blocked the main loop (`prof_run`) while launching an external editor like `vim`, halting network I/O in `session_process_events` and preventing incoming message reception.
Introduced `get_message_from_editor_async` for `cmd_editor` to run the editor asynchronously. It forks and execs the editor in a thread (`editor_thread`), suspending NCurses to free the terminal. The main loop skips `inp_readline` and `ui_update` via a new `background_mode` flag while the editor runs, allowing `session_process_events` to keep the connection alive.
On editor completion, `editor_process` (called per loop iteration) resumes NCurses with `ui_resize`, inserts the result into the readline buffer and clears `background_mode`.
Retained synchronous `get_message_from_editor` for ~20 existing code paths (e.g., `vcard_nickname`) to avoid breaking them.
Tested with `vim` and `nano`: confirms no rendering conflicts, messages received during editing, and seamless resume. Edge cases like editor crashes handled via error logging and seamless resume.
Previously, features like `XMPP_FEATURE_OMEMO_DEVICELIST_NOTIFY` were
added in separate init methods (e.g., `omemo_devicelist_subscribe`) via
`caps_add_feature`, triggering `cl_ev_presence_send` and sending multiple
"online" XMPP presence stanzas. This caused other clients to see users
as appearing "online" multiple times.
This change adds `STANZA_NS_MOOD_NOTIFY` and
`XMPP_FEATURE_OMEMO_DEVICELIST_NOTIFY` in `caps_init`, ensuring they are
in `prof_features` early. This allows `caps_add_feature` to exit early
when called for these features, avoiding redundant presence updates.
When paging down beyond the visible chat buffer, the scroll position could
jump unexpectedly. This occurred because the visual distance from the bottom
(e.g. 6 lines until the last message) wasn’t preserved after loading new
messages from the DB.
This patch fixes that by capturing the visual offset (`current_offset`) before
the DB fetch and reapplying it after, based on the y-position of the final
buffer entry. This ensures consistent and smooth scroll transitions, even
as message heights vary.
In addition to fixing the visual glitch, this commit introduces a targeted
performance optimization: once the bottom of the chat has been reached
(`WIN_SCROLL_REACHED_BOTTOM`), we skip expensive operations entirely —
including datetime lookups and entry formatting — during further page_down
events. This reduces performance stalls
during rapid paging (e.g. holding the Page Down key at the bottom of the scrolling area).
This update also adapts to the recent change in `chatwin_db_history()`,
which now returns a `db_history_result_t` instead of `gboolean`, allowing
correct differentiation between an empty result and an actual DB error.
Together, these changes:
- Fix a scroll-jump bug in `page_down`
- Improve performance and responsiveness during rapid navigation
- Align with improved DB result handling
The function did not decref the Python object on type error paths,
resulting in a reference count leak. This caused memory to accumulate
over time. Added Py_XDECREF on all early return paths to properly free
the Python object reference and prevent leaks.
- Introduce static helper `_truncate_datetime_suffix()` to safely trim datetime strings, removing unwanted suffixes like timezone offsets
- Replace manual string management with auto_gchar and g_strdup for safer, clearer ownership and to prevent leaks
- Add safety checks and logging warnings for unexpected datetime string lengths or null pointers
- Refactor _mam_rsm_id_handler to use the helper function and updated string handling
- Change log_database_get_previous_chat parameters for consistent ownership semantics, avoiding double frees and mem leaks
- Overall improve stability and prevent memory leaks during log database queries
This commit refines the existing logic in win_page_up() by:
- Improving comments to clearly explain the rationale behind adjusting
the scroll offset relative to the first buffer entry’s visual position,
helping future maintainers understand why this is necessary.
- Fixing offset recalculation to better handle cases where older messages
with variable heights are loaded from the DB, improving scroll smoothness.
- Changing the logging of negative *page_start values from warning to debug,
recognizing that this can be a normal scenario when insufficient history is loaded.
- Simplifying some conditionals and renaming variables for clearer intent.
No changes yet applied to win_page_down(), but similar improvements could
be considered in the future.
Overall, this enhances the robustness and user experience of scrolling up
in chat windows, while preserving existing functional logic.
f27fa98 commit introduced issue of scrolling seemingly randomly being stuck and the following message flood in the logs: "WRN: Ncurses Overflow..."
A pad is an off-screen buffer — larger than the visible terminal screen — that you can scroll, render parts of, or update selectively.
Unlike regular windows, a pad is not tied to screen size. You can create a pad that's 1,000 lines tall, even if your terminal is only 40 lines tall.
This commit addresses the issue by increasing PAD_SIZE to a reasonable number,
allowing messages from buffer to be displayed without overflowing NCurses' window size (maxy).
Minor change: add .cache folder to gitignore
