In addition to providing a new `xref' backend, the patch also improves
the general handling of expl3 syntax. Expl3 is the next-generation
LaTeX specification, and has for some time been available by default in
the LaTeX kernel. The new syntax co-exists in many files with the
standard LaTeX2e syntax, so we try at least minimally to separate the
way modes handle the two specifications, both to reduce
visually-disturbing interference between them and also to improve the
`xref' backend. (Bug#53749)

in 'occur-edit-mode' by using the 'occur' framework.
(grep-mode-map): Bind 'e' to the new command
'grep-change-to-grep-edit-mode'.

manual to include the above command.

In 03ac16ece4 I fixed a bug with the
PCM implementation of substring completion, relating to the handling
of PCM wildcards.
However, this fix was incomplete. This change completes the fix by
also including a fixed string if it appears before a 'prefix'
wildcard, even if 'try-completion' doesn't discover that fixed
string grows to a unique completion.
I discovered this bug while working on enhancements to PCM
completion related to 'completion-pcm-leading-wildcard'.
* lisp/minibuffer.el (completion-pcm--merge-completions): Include
fixed strings before 'prefix wildcard. (Bug#72819)
* test/lisp/minibuffer-tests.el (completion-substring-test-5): Add a
test for this behavior.
* doc/lispref/keymaps.texi (Easy Menu):
* lisp/emacs-lisp/easymenu.el (easy-menu-define): Document that
SYMBOL is also defined as a variable. (Bug#73108)
In 69ec333eab I allowed
completion-styles to contain a list of bindings. Now the
'defcustom' type also supports this.
Since the type is somewhat unusual (a value in the list can be
either a symbol or a list) I had to add a new widget to support
it.
* lisp/minibuffer.el (completion--styles-type): Update to allow
setting variable overrides.
(completion-styles, completion-category-overrides)
(completion-pcm-leading-wildcard): Update :version.
* lisp/wid-edit.el (widget-single-or-list-to-internal)
(single-or-list): Add.
For buffers with multiple parsers, it's important to set this variable
so font-lock invalidation works smoothly.
* lisp/progmodes/c-ts-mode.el (c-ts-mode): Set treesit-primary-parser.
* lisp/progmodes/elixir-ts-mode.el (elixir-ts-mode): Set
treesit-primary-parser.
Here by multibyte buffer I mean buffer that includes non-ASCII
characters.
The problem is illustrated by this comment, which I copied from the
source:
======================================================================
(ref:bytepos-range-pitfall) Suppose we have the following buffer
content ([ ] is a unibyte char, [ ] is a multibyte char):
[a][b][c][d][e][ f ]
and the following ranges (denoted by braces):
[a][b][c][d][e][ f ]
{ }{ }
So far so good, now user deletes a unibyte char at the beginning:
[b][c][d][e][ f ]
{ }{ }
Oops, now our range cuts into the multibyte char, bad!
======================================================================
* src/treesit.c (treesit_debug_print_parser_list): Minor fix.
(treesit_sync_visible_region): Change the way we fixup ranges, instead
of using the bytepos ranges from tree-sitter, we use the cached lisp
charpos ranges.
(treesit_make_ts_ranges): New function.
(Ftreesit_parser_set_included_ranges): Refactor out the new function
treesit_make_ts_ranges.
(Ftreesit_parser_included_ranges): Rather than getting the ranges from
tree-sitter, just return the cached lisp ranges.
* src/treesit.h (Lisp_TS_Parser): Add some comment.
* test/src/treesit-tests.el (treesit-range-fixup-after-edit): New test.
This reverts commit bf23382f1f.
We move around the gap, narrow regions, ralloc, etc, and don't have a
way to invalidate previously given range. So tree-sitter can't be given
the full range.
* admin/notes/unicode: Point people at "admin/unidata/README" for URLs
for Unicode files.
* admin/unidata/README: Use stable URLs for the various files. Remove
dates, the files self-describe their dates anyway.
* lisp/international/characters.el: Assign 'digit' category to all
the characters whose Unicode 'general-category' is Nd.
* admin/unidata/blocks.awk: Add code to assign 'symbol' category
to all characters belonging to the 'symbol' script.
* etc/NEWS: Announce the above changes
