- set `MAN_KEEP_FORMATTING=1` and `MANPAGER=cat` for the man
command and handle overstriking in the terminal emulation.
- this approach works on macOS, linux, FreeBSD and OpenBSD
- apply infinite-height prior to winsize initialization.
- use `LESS_LINES` environment variable.
- use `PAGER=less -F` to make less quit at the end of the man page
The behavior follows this priority order:
1. reuse an existing window already displaying the buffer,
2. if shell-command-other-window is not set, use the current
window, otherwise
3. select the largest available non-active window.
4. split a new window if no sutiable window is found.
5. fall back to the current window if splitting fails.
* use `BC_REUSE | BC_CLEAR` to avoid killing the `*occur*` buffer
* this ensures the `*occur*` buffer stays current in windows that show it
* modify the `BC_CLEAR` semantics to imply `BC_REUSE`
* simplify calls: remove redundant `BC_REUSE` flag
- `shell_buffer_read_only` controls if the shell buffer should become
read-only and use pager-mode when not interactive
- `shell_mode_auto_interactive` controls if the shell interactive mode is
switched to and from automatically based on cursor movement commands
- disable auto interactive if region is highlighted
- fix crash bug in qe_register_emulation_bindings for "emacs" emulation
* 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 `?`
