* fix crash bug on Linux when `set_style` is called from the config file
for the `"default"` style.
* the `dummy_dpy` was not intialized properly, causing a division by zero
error reported as `Program received signal SIGFPE, Arithmetic exception.`
* this bug was harmless on Apple M1 and later processors because zero division
does not cause an exception on such hardware.
* fixes#207
* reorganize style attribute bits in `QEStyleDef`
* support more `text-decoration` bits (overline, line-through and box)
* add `css_get_enum_bits` to support `text-decoration` combinations
* fix sorting color issue: move newline with its style in `eb_sort_span`
* add completion handlers for style attributes, style and color names
* add `check_default_style` to prevent invalid default style
* improve style output in `list-styles` and style completion
* add `modify-style` command
* group urlio data into an `URLState` structure
* allocate `URLState` in `url_init()` and store it into the `QEmacsState`
* pass the `URLState` pointer to all `url_xxx` APIs
* add `tail_cb` for redisplay requests
* remove global variables
* simplify `qe_init()` call sequence
* add `QE_LIST_INIT` to initialize a linux doubly linked list
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.
- char32_t is defined in cutils.h but may conflict with <uchar.h>
- all qe_isxxx functions take a char32_t
- add etf8x encoding for full range of char32_t type
- add utf8_decode_strict()
- add ustr_match_keyword()
- utf8_encode() / utf8_decode() handle up to 32 bits
- improve detect_charset():
- detect utf8 and utf8x
- avoid failure on partial utf8 sequence at end of buffer
- detect overlong utf8 sequences
- fix display bugs for code points beyond MAX_UNICODE_DISPLAY
- simplify do_compare_windows(), avoid magic char values.
- rename functions:
eb_encode_uchar -> eb_encode_char32
eb_insert_uchar -> eb_insert_char32
eb_insert_uchars -> eb_insert_char32_n
eb_match_uchar -> eb_match_char32
eb_delete_uchar -> eb_delete_char32
eb_replace_uchar -> eb_replace_char32
utf8_to_unicode -> utf8_to_char32
- use char32_t for all variables and arrays holding code-points
- fix some language syntax parsers.
- fix detect_eol_type_32bit(), used uint16_t instead of uint32_t
- bump VERSION to 5.4.0
- add bitmap formats for 4BPP and BGR combinations
- add color palette in QEPicture
- add xfactor and yfactor in QEDisplay for preferred pixel granularity
yfactor is typically 2 for text mode display
- add dpy_draw_picture() device function
- add bitmap drawing functions:
qe_create_picture(int width, int height, QEBitmapFormat format, int flags);
int qe_picture_lock(QEPicture *ip);
void qe_picture_unlock(QEPicture *ip);
qe_free_picture(QEPicture **ipp);
QE_PAL_MODE(r, g, b, incr)
int qe_picture_set_palette(QEPicture *ip, int mode,
unsigned char *p, int count, int tcolor);
int qe_picture_copy(QEPicture *dst, int dst_x, int dst_y, int dst_w, int dst_h,
const QEPicture *src, int src_x, int src_y, int src_w, int src_h,
int flags);
int qe_draw_picture(QEditScreen *s, int dst_x, int dst_y, int dst_w, int dst_h,
const QEPicture *ip,
int src_x, int src_y, int src_w, int src_h,
int flags, QEColor col);
- add 3 compile time selectable image interfaces in flactal.c benchmark
- add wrappers in display.h
- renamed tty dpy_xxx handlers for consistency
- separate tty_term_resize called on signal and tty_dpy_invalidate
- add dpy_xor_rectangle for software cursor, remove QECOLOR_XOR
- rename font styles QE_STYLE_xxx to QE_FONT_STYLE_xxx
- rename font family QE_FAMILY_xxx to QE_FONT_FAMILY_xxx
- improve tests/16colors.pl: display bold italics combination
- improve tests/color-spaces.pl: compare true color and palette dumps
- add colortest target in Makefile to produce various color patterns
* use qe_mallocz for all structures
* prevent spurious uses of malloc/free/realloc
* pass pointers to pointers to all deletion functions
* use consistent patterns for list deletions
* add more dependencies in Makefiles
* remove unused variables/functions
* remove commented out debug output
* make haiku_dpy static; no need to memcpy() it
* Fix calling [un]init_appplication()
* Fix hardcoded -ldl and -lm in the Makefile
* BeOS does not have -lm (it's part of libroot)
* Add Haiku GUI driver haiku.cpp
* Add helper script haiku-pe2qe.sh to clone color settings from Pe to Qemacs
