* `delete-leading-space`: Delete any leading whitespace on the current line
* `delete-trailing-space`: Delete any trailing whitespace on the current line
* `delete-trailing-whitespace` Delete all the trailing whitespace across the current buffer.
These commands handle the region if highlighted
* 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 `?`
- `canonicalize_path` returns destination array
allow for destination to overlap source
- `qe_strcollate` compare directory name before contents
this fixes the pathnames sorting
- add `get_relativename(filename, dirname)`
Simple regexp patterns use a subset of POSIX regexp:
- only simple character classes, no escape sequences
- no assertions (except $), no backreferences
- embedded groups always generate maximal matches which
may cause the outer expression to fail match
* 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
- add `swap_int()`
- add commands for multi-line cursor:
* `start-multi-cursor` on `C-x <`
set the mark for a region with a cursor on each line
* `end-multi-cursor` on `C-x >`
end recording the multi-line cursor region and start editing
cancel the multi-line cursor with `C-g`
* `add-multi-cursor` on `C-x #`
add an extra cursor at point. Activate multi-line cursor editing
with `C-x \`
* `activate-multi-cursor` on `C-x \`
start multi-line cursor editing. Stop with C-g.
- UX is tentative, more work needed based on usage.
- replace `qe_malloc_dup()` with `qe_malloc_dup_bytes()` and `qe_malloc_dup_array()`
- replace `qe_realloc()` with `qe_realloc_bytes()` and `qe_realloc_array()`
- pass numbers of objects to `qe_malloc_dup_array` and `qe_realloc_array`
- add `qe_strndup()`
* Do not use CFLAGS for host tools when cross-compiling.
* Add a missing $(EXE). Maybe we should have a HOST_EXE but at least we can build.
* set target OS & CPU
Not really used, only for cosmetics.
Also, m68k is big endian. (Do we use this anywhere yet?)
* Force GNU-C99 standard for LLONG_MIN
* work around missing d_type in dirent struct
* 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
* adjusted `ustr_match_keyword` for consistency
* implement `byte_quote` natively
* implement `buf_byte_quote` using `byte_quote` instead of the reverse
* rename `buf_encode_byte()` as `buf_quote_byte()`
* change `buf_printf` return value for consistency
* let `strquote` always return the length of the conversion like `snprintf`
- 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
- make `do-goto` accept a 1-based column number
- parse 1-based column numbers in filenames from the command line
- display 1-based column number in status lines
*equivalents* are strings that should compare equal in a `compare-windows`
session. You can define such strings in a **.qerc** file in the directory of
one of the files being compared. This helps ignoring known changes such as
type of function renaming... Here is an example to help compare files between
the `bellard/quickjs` and the `quickjs-ng/quickjs` repositories:
```
define_equivalent("JS_DupValue(ctx, ", "js_dup(");
define_equivalent("JSValue", "JSValueConst");
define_equivalent("JS_NewInt32(ctx, ", "js_int32(");
define_equivalent("JS_NewInt32(ctx,\n", "js_int32(");
define_equivalent("JS_NewUint32(ctx, ", "js_uint32(");
define_equivalent("JS_NewUint32(ctx,\n", "js_uint32(");
define_equivalent("JS_NewBool(ctx, ", "js_bool(");
define_equivalent("JS_NewFloat64(ctx, ", "js_float64(");
define_equivalent("JS_EXTERN ", "");
define_equivalent("JS_EXTERN JS", "JS");
define_equivalent("JS_EXTERN JS_", "JS_");
ignore_equivalent = 1;
```
Other changes were necessary for proper utf8 skipping:
- add `utf8_prefix_len(str1, str2)` to compute the length of a common initial
prefix not falling inside UTF-8 encoded codepoints.
- add `utf8_decode_prev` to get the previous codepoint
- add `eb_match_str_utf8_reverse`
