* decouple interactive mode from cursor position.
* clear readonly when entering interactive mode and
restore when leaving it.
* simplify navigation logic by removing offset-based toggling.
* set pager mode on interactive shell exit.
* check for active processes in shell buffers before reusing them,
and prompt the user to kill the running process to avoid leaving
it detached and unreachable.
fixes a race condition where pty data was lost on process exit.
The pid callback now flags the exit status, while `shell_read_cb`
handles the final teardown. This prevents truncation for
high-throughput processes.
* fix bug in `eb_free` where log and style buffers were not freed
* free minibuffer history list
* free css symbols when finalizing the graphics html viewer
- rename `edit_new` as `qe_new_window`
- report error in `qe_new_buffer` and `qe_new_window` upon failure
- rename `qe_find_buffer_file` as `qe_find_buffer_filename`
- rename `read_charset` as `qe_parse_charset`
- reset yank buffer references in `eb_clear()`
- make `qe_init()` return error code and abort upon error
* Fix `put_status`/`put_error` behavior
- use `put_error` instead of `put_status` for command errors
- prevent status message output to console during initialization
- use `put_error` for side effects in command errors
- add `&` prefix in status messages to force screen flush
- flush screen in `qe_display()`, remove redundant calls to `dpy_flush`
- fix gcc compilation errors and warnings
- remove most references to `global_screen`
- free font cache before closing the screen
- prevent mouse handling upon focus detection
* drop CI on macos-12
Mouse:
- add `shift` state in all mouse events
- pass `QEmacsState *qs` to `qe_mouse_event`
- support non drag mouse events with `-m:2` command line option
- dragging beyond window borders generates scrolling events
(should autorepeat, should have menu line at the top for scrolling up)
- cancel active search on mouse_goto
- do not mouse activate window if current active window is modal (popup or
minibuf)
- handle double and triple click: select by words or lines
- handle shift click: extend selection
- add `EditState::mouse_down_offset` for initial dragging buffer offset
- pass `QEEvent *ev` to `mouse_goto()` handlers
events:
- add synthetic key events: QUIT CLOSE EXIT
- use synthetic events for GUI interaction (no longer simulate keystrokes)
tty:
- fix large OSC sequence support for terminal clipboard retrieval
Multicursor:
- use new `QECursor` for multicursor local states
- reallocate `multi_cursor` array in chunks
misc:
- add `eb_peekc(EditBuffer *b, int offset)`
- boolean cmdline options no longer require an argument, true if none provided
- int cmdline options either require an argument (CMD_LINE_INT_ARG) or take an
optional argument, value is incremented if argument is not provided.
- intialize `tty_mk`, `tty_mouse` and `tty_clipboard` to `-1` for automatic
- command line options force setting
- otherwise, configure support from environment variables (for now)
* add hierarchical view in dired left panel:
- left on closed dir or file moves to parent dir
- left on closed dir or file with no parent inserts the open parent dir at the top
- right on closed dir opens the directory
- right on open dir goes down to last visited item in this list or first if none
- right on file skips to the right window in preview mode
- space on directory expands or collapses it
* add `do_dired_path()`
* fix `qe_load_file()` for directories specified as relative paths
* fix `qe_load_file()` loading a directory into the dired left panel
* add dired sorting by fullname
* fix directory grouping for non alpha sort
* use direct array of `DiredItem` instead of `StringArray`
* add `dired_ignore_extensions[]`
* add `classify_fullnames()` to help with tree sorting
* add completion on `dired-sort` prompt
* add `dired-summary` on `?`
* add `find_indent` and `make_indent` ancillary functions
* add `untabulate` on `S-TAB` to remove one indentation level
* rename `do_tab` as `do_tabulate` for consistency
* `tabulate` indents the region one level if visible
* add `indent-rigidly` commands: indent block interactively
* pass const `char32_t` array and `QETermStyle` array to `ColorizeFunc`
* add `cp_colorize_line()` wrapper to call colorizer function on null
terminated buffer.
* remove unused `EditBuffer` colorize fields
* remove `EditState` field `colorize_func`: rely on `colorize_mode` only
* no longer combine style into codepoint buffer.
* remove `STYLE_BITS`, `STYLE_SHIFT`, `CHAR_MASK`
* rename `set_colorize_func` as `set_colorize_mode`
* rename `SET_COLOR` and `SET_COLOR1` as `SET_STYLE` and `SET_STYLE1`
* add documentation for buffer API functions
- add `repeat` command on `C-x z`
- add `repeat-mode`, always enabled
- cycle all matching tags in current file on `goto-tag` and `find-tag`
- set up `repeat-mode` for these commands:
- `undo` on `C-x u` (`u` repeats `undo`, `r` performs `redo`)
- `undo` on `C-x r` (`r` repeats `redo`, `u` performs `undo`)
- `find-window-left`, `find-window-right`, `find-window-up`, `find-window-dow`
repeat navigation on `up`, `down`, `left`, `right`
- `next-error`, `previous-error`: `M-n` and `M-p` repeat in corresponding direction
- `next-buffer`, `previous-buffer: repeat buffers nagivation with `left` and `right`
- `enlarge-window` / `shrink-window`: repeat resizing on `^`, `v`, `{`, `}`
and cursor movement keys
- `goto-tag` on `C-x ,` goto next tag with `,` and `.`
- `call-last-kbd-macro` on `C-x e`: repeat macro on `e`
- add `eb_count_buffers` and `eb_get_buffer_from_index` for safe buffer navigation
- add transient bindings, known as repeat maps in GNU emacs
- pass `KeyDef **lp` (aka key maps) instead of mode for binding commands
- replace `do_next_buffer` and `do_prevous_buffer` with repeatable command
`do_buffer_navigation`
- fix `bufed_select` crash bug when selecting buffer from a regular window
