- add charset.h
- add tools/unitable.c to compute unicode_width.h
- add tools/unicode_gen.c to compute more unicode tables
- use Unicode 15.0.0
- add rules to compute width tables from Unicode tables and TTY
- move basic definitions from util.h to cutils.h
- use CONFIG_SESSION for session support (undefined if CONFIG_TINY)
- define CompleteFunc and CT_xxx flags for completion functions
- pass CompleteFunc to xxx_complete() functions
this allows more generic implemetation, without including qe.h
- rename fill_border() as fill_window_slack() for readability
- add QELEVEL environment variable to detect recursive invocation
- use stricter parser for load_ligatures()
- bump VERSION to 5.3.4u
- add QE_STYLE_BLANK_HILITE style for extra blanks at end of lines
- add MODEF_NO_TRAILING_BLANKS flag to control this feature on a mode basis
- add -nc (--no-crc) command line option du disable CRC based update cache
- add disable-crc global variable for the same purpose
- fix termios c_oflag flags in raw mode
- add st_errno in ModeProbeData so dired only matches wildcards if no
file exists with that exact name (argument passed probe_mode())
- add LF_NOWILDCARD qe_load_file flag to prevent wildcard handling
- display line numbers and terminal right margin in new gutter style
- free EditState:line_shadow display CRCs when changing modes:
this fixes an old display bug when switching between html and text mode
- added convenient default bindings:
C-c ~ -> toggle-read-only
C-c c -> set-buffer-file-coding-system
C-c b -> toggle-bidir
C-c C-\ -> set-input-method
C-c l -> toggle-line-numbers
C-c t -> toggle-truncate-lines
C-c w -> word-wrap
- disable terminal emulation on shell buffers without the SF_COLOR flag
- only update mark on process output in interactive terminal emulator buffers
- only compute shell current directory on terminal emulator buffers
- auto select mode and character set after 3MB of output
- update wrap_cols on all windows upon shell-refresh (C-l in shell-mode)
- improve shell_get_curpath(): handle debian default prompt
- updated TODOs
- 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
- fix bug with word-match incremental search
- pass max offset to eb_search
- simplify search code, keep separate u32 and flag arrays
- add ISearchState* to EditWindow to display current or last matches
- add style for search matches
- clean search and replace code
- fix point position upon matches in forward and backward directions
- prevent reverse search from find overlapping matches
- hilite current match
- add style search-match to hilite the current match in incremental-search
defaults to cyan / magenta
- C-l centers the window
- C-q quotes next character in incremental search
- C-w grabs the word at point
- C-y grabs from point to next end of line
- A-b cycles unihex hex and normal search
- A-w toggles word matching
- A-y yanks last kill in search string
- add same control keys to query-replace command
- fix searching and replacing in hex and unihex modes
- wrap search after failure
- pass search data as u32 buffer
- add eb_insert_u32_buf(b, offset, buf, len) to insert unicode code points
- add window.offset_end -> offset of first char beyond the window
- add qestate.emulation_flags to select between standard emacs behaviour and
alternate behaviours in internal commands
- fix do_center_cursor() when point is before window start
- add do_center_cursor_maybe() to center window if point is not visible
- allow C-q to quote DEL key (ASCII 127)
changed API for GetColorizedLineFunc: offset passed by address,
updated to start of next line
added check_readonly(EditState *s)
added tentative code for unregistring bindings, cycling modes and charsets
experiment alternate method for region highlighting:
added EditState.region_style and EditState.curline_style
added QEmacsState.hilite_region
added DisplayState.style
added clear_color to reset style bits in unicode array
display_char_bidir takes style from DisplayState, code point is bare.
fixed problem in text_display where line_num was not computed in shell mode
handle region coloring in text_display (tentative)
display line numbers and hex dump offsets as QE_STYLE_COMMENT
display hex dump as QE_STYLE_FUNCTION
renamed canonize to canonicalize
added crude support for ~user -> /home/user
added win32 specific stuff in basename
added C-/ as an alias for C-_
some cosmetics, moved code
create files with mode 0644 in raw_save_buffer
untabified, removed redundant spaces
modified code generators to the same effect
added Makefile mode: makemode.c
added HTML source mode: htmlsrc.c
added more dependencies in Makefile
added styles for HTML source coloring:
html-comment, html-string, html-script, html-entity, html-tag
no longer rely on \n at end of line in c_colorize_line
