* add `eb_put_filename()` to encode buffer or file names with
non-ASCII characters according to PF_xxx flags
* add `CF_SAVE_LIST` flag for completions to store the list
of matches in `MinibufState`
* fix bufed and dired layout issues
* fix buffer and filename completion popup layout
* add commands to control display of Unicode and non printing
charcaters in buffer or file names:
- U toggles unicode display
- \ cycles through 4 possible encodings: ? ^J \x10 \010
* use `(*fp)()` syntax for indirect function calls
* 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
- 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 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
- rename and extend CompletionEntry as CompletionDef
- create xxx_completion CompletionDef structures
- rename xxx_completion() functions to xxx_complete()
- register CompletionDef structs with qe_register_completion()
- add (start, end) range in CompleteState
- use eb_puts() and eb_putc() instead of eb_printf()
- simplify eb_delete_chars()
- ignore left pane in compare-windows()
- simplify qe_list_bindings()
- improve command and variable completion popup
- add qe_digit_value(): returns arithmetic value of character
- single test in qe_inrange()
- simplify qe_isxdigit() and use qe_isxdigit_()
- remove to_hex()
- hex.c: use qe_digit_value() instead of to_hex()
- update TODO.org, README
- bump VERSION to 5.2alpha
added CONFIG_MMAP to control availability of memory mapped files
added CONFIG_DOC to control doc rebuild
use state variables to control file mmapping and loading
default limit of 512MB for loading file
try and load the file upon mmap failure
do not use alloca in CONFIG_WIN32
use CONFIG_WIN32 instead of WIN32
update Makefile to enable win32 build under cygwin (dumps core)
renamed mouse_event to prevent compile warning
patched unix.c util.c win32.c to enable WIN32 compile
fixed kmap.c to load mapping files when mmap fails or is unavailable
qe_register_binding takes ModeDef* and returns status
cosmetic changes in QEDisplay API
added int dpy_init(QEditScreen *s, QEDisplay *dpy, int w, int h);
copies *dpy (or dummy_dpy if NULL) to QEditScreen and calls method
simplified dpy_init methods and calls
inlined 5 more methods
moved dummy_dpy to display.c and simplified
simplified to_hex
simplified qe_colors array handling
- use CompleteState struct
- use complete_test for each potential match with simple prefix comparison
added new smart string compare function qe_collate to sort strings in
lexicographical order but sort numeric portions in numerical order
use qe_collate in popup lists and dired
removed redundant alias "iso8859-2"
added strequal(a,b) as an alias for !strcmp(a,b)
this function makes string collation with strcmp more explicit
this even fixed a spurious bug in do_set_emulation
use match_extension in mode probe functions
pass move indicator to do_return, removed do_open_line
renamed do_cmd_set_mode -> do_set_mode for consistency
separated strfind and strcasefind, optimized implementation
published register_input_method
unpublished input_methods
optimized KeyDef structure layout
changed eb_search arguments
used eb_delete_range
comments, remarks
better tests on fread failures
set buffer to read-only upon loading non writable file
do_insert_file tests for failure
set mark at beginning of inserted block and offset at the end
fixed search for word boundary case
made raw_load_buffer1 return number of bytes read, of -1 on error
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
utf8_encode now returns the number of characters copied,
simplified code accordingly
made local functions static
tagged unused function arguments
fixed shadowing issues
added support for GCC attributes for unused arguments and format strings
use snprintf() instead of sprintf()
moved scattered declarations to qe.h
removed duplicate declarations in header files
eb_write() payload argument is now const
fixed crash bug: reset trace_buffer upon deletion
improved trace_buffer readability: trace all pseudo tty streams separately
added missing structure initializers
removed buffered string handling from cutils.h
added new buffered string API for statically allocated buffers (should unify)
small improvements in X11 initialization
improved consistency in tty.c (function names...)
added STDIN and STDOUT streams in QEditScreen to stop using stdin and stdout
use unlocked stream I/O if available (faster)
changed and documented terminal setup and exit sequences
improved charset handling
mode_line functions now return the character count (like snprintf)
