Both 'c-ts-mode' and 'java-ts-mode' have a new user option,
'c-ts-mode-enable-doxygen' and 'java-ts-mode-enable-doxygen'
(defaults to nil) which allow to enable syntax highlighting
of comment blocks based on the Doxygen grammar.
* lisp/progmodes/c-ts-mode.el: Add the 'c-ts-mode-enable-doxygen'
user option variable to disable doxygen grammar.
Notifies the user if doxygen grammar is not available.
* lisp/progmodes/c-ts-mode.el (c-ts-mode, c++-ts-mode): Use the
new 'c-ts-mode-enable-doxygen' option.
* lisp/progmodes/java-ts-mode.el: Add the
'java-ts-mode-enable-doxygen' user option variable to disable
doxygen grammar. Notifies the user if doxygen grammar is not
available.
* lisp/progmodes/java-ts-mode.el (java-ts-mode): Use the new
'java-ts-mode-enable-doxygen' option.
* etc/NEWS: Document the change.
* src/search.c (Freplace_match): Remove the test that
search_regs.num_regs != num_regs. It is deemed unnecessary now,
and could produce false positives. (Bug#73018)
Since each SETTING in treesit-font-lock-settings is considered an opaque
object, provide accessor functions for each field.
* lisp/treesit.el:
(treesit-font-lock-settings): Update docstring.
(treesit-font-lock-setting-query):
(treesit-font-lock-setting-enable):
(treesit-font-lock-setting-feature):
(treesit-font-lock-setting-override): New functions.
(treesit--font-lock-setting-feature): Remove function.
(treesit--font-lock-setting-enable): Rename to
treesit--font-lock-setting-clone-enable to avoid confusion with
treesit-font-lock-setting-enable.
(treesit-add-font-lock-rules): Use renamed function.
(treesit-font-lock-fontify-region): Add a comment.
* doc/lispref/modes.texi (Parser-based Font Lock): Update manual.
* etc/NEWS: Delete bug fix item. No correct program will see a
difference in behavior; at worst, the error message when calling
`(error)` is now better.
Reported by Mattias Engdegård <mattias.engdegard@gmail.com>.
Instead of setting the highlight overlay on every line in the selection,
only do so on the window-height worth of lines closest to point because
the rest aren't likely to be visible.
This makes a massive difference for tall rectangular selections which
previously were so slow as to be unusable.
(Tall selections are still slow if `select-active-regions` is non-nil,
but that is something that users can actually do something about.)
* lisp/rect.el (rectangle--highlight-for-redisplay)
(rectangle--unhighlight-for-redisplay):
Replace call to `apply-on-rectangle`, which operates on every line,
with a loop over an approximate screenful.
Extend the `rectangle` overlay list structure with a value for point,
because `exchange-point-and-mark` must trigger a recomputation of
highlight overlays despite the selection not actually changing.
let-alist is very useful. But sometimes an alist contains a list in
the middle, which contains yet more alists. Previously, this was
somewhat painful to deal with, and required something like:
(let-alist alist
(let-alist (nth 0 .a)
(let-alist (nth 3 .b)
.c)))
Now, the following works:
(let-alist alist
.a.0.b.3.c)
* lisp/emacs-lisp/let-alist.el (let-alist--access-sexp): Properly
parse numbers to handle lists. (Bug#66509)
(let-alist--list-to-sexp): Use nth to handle numbers.
(let-alist): Update docs.
* lisp/simple.el (kill-region-dwim): Move the default nil
to the top of choices.
(kill-region): Set the FORCE argument of 'mark' to non-nil
if kill-region-dwim is non-nil. That allows everyone to use
non-nil kill-region-dwim even if mark-even-if-inactive is nil.
Don't check 'last-command' if kill-region-dwim is non-nil.
That allows everyone to type C-w twice in a row to delete
two previous words.
* src/fns.c: Do not include syntax.h; no longer needed.
(Fyes_or_no_p): Use blankp rather than SYNTAX to check whether the
prompt ends in nonspace. That way, the test doesn’t depend on the
current buffer.
Libraries like `socks' need to run `nsm-verify-connection' without
performing DNS lookups. This change allows them to achieve this by
binding `nsm-trust-local-network' to nil around calls to that function.
* lisp/net/nsm.el (nsm-should-check): Rework in a functionally
equivalent way, except forgo calling both `network-lookup-address-info'
and `network-interface-list' unless the various conditions regarding
`nsm-trust-local-network' are first satisfied. Replace `mapc' with
`dolist' to align with modern sensibilities. (Bug#53941)
This fixes some unlikely bugs and removes the temptation
of using ctype.h. Although some uses were correct,
many weren't.
* lib-src/ebrowse.c: Include c-ctype.h, not ctype.h.
* lib-src/emacsclient.c: Include c-ctype.h, not ctype.h.
* lib-src/update-game-score.c: Include c-ctype.h, not ctype.h.
All uses changed.
* exec/exec.c: Do not include ctype.h, as the kernel
does not care about the locale.
(check_interpreter): Treat only spaces and tabs as white space.
Do not inspect more bytes than were read.
Although the resulting code does not exactly match what
the Android kernel does, it’s closer than what it was before.
Problem reported by Thomas Klausner (Bug#73307).
Emacs shouldn’t use ctype.h, as it doesn’t work for multibyte
chars and it doesn’t work with Emacs’s locale model anyway.
* src/fns.c: Include syntax.h, not ctype.h.
(Fyes_or_no_p): Check the character category with SYNTAX, not
with isspace, which assumes the current locale and works only
with single-byte characters.
Completion Preview mode implicitly assumed that
'completion-ignore-case' is nil, and while it can also work
with 'completion-ignore-case' non-nil, the results are a bit
different than what you get with 'completion-at-point'. Add
an option that controls case sensitivity explicitly and
specifically for Completion Preview mode, and clarify the
behavior when case differences are ignored. (Bug#73234)
* lisp/completion-preview.el
(completion-preview-ignore-case): New user option.
The latest version of UTS #46 in Unicode 16 has changed the way it
indicates which codepoints are invalid in domain names, causing
'idna-mapping-table' to contain incorrect information, which then breaks
'textsec-domain-suspicious-p' and our test suite. (Bug#73312)
* admin/unidata/unidata-gen.el (unidata-gen-idna-mapping): Check the
IDNA validity field in "IdnaMappingTable.txt" in addition to checking
the status field, as the latter can now be 'valid' for disallowed
codepoints.
The 'initialize-new-tags-table' function is unconditionally available
after 'etags' has been loaded, which is done further up.
* lisp/progmodes/cperl-mode.el (cperl-write-tags): Remove XEmacs compat
code.
* lisp/progmodes/c-ts-mode.el:
(c-ts-mode--keywords): Add "thread_local" keyword.
(c-ts-mode--test-virtual-named-p): New function.
(c-ts-mode--font-lock-settings): Use named/anonymous "virtual" depending
on the grammar.
* admin/MAINTAINERS: Add entry for externally maintained Transient
package.
* doc/misc/transient.texi: Bump version strings.
* lisp/transient.el: Bump version in Version header.
* lisp/transient.el (transient-version): New constant.
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)
* lib-src/etags.c (TeX_commands): Improve parsing of commands in TeX
buffers.
(TEX_defenv): Expand list of commands to tag by default in TeX buffers.
(TeX_help):
* doc/emacs/maintaining.texi (Tag Syntax): Document new tagged commands.
(Identifier Search): Add note about semantic-symref-filepattern-alist,
auto-mode-alist, and xref-find-references.
* lisp/textmodes/tex-mode.el (tex-font-lock-suscript): Test for
underscore in expl3 files and regions, disable subscript face there.
(tex-common-initialization): Set up xref backend for in-tree TeX modes.
Detect expl3 files, and in others set up a list of expl3 regions.
(tex-expl-buffer-parse): New function called in previous.
(tex-expl-buffer-p): New variable to hold the result of previous.
(tex-expl-region-set): New function added to
'syntax-propertize-extend-region-functions' hook.
(tex-expl-region-list): New variable to hold the result of previous.
(tex--xref-backend): New function to identify the xref backend.
(tex--thing-at-point, tex-thingatpt--beginning-of-symbol)
(tex-thingatpt--end-of-symbol, tex--bounds-of-symbol-at-point):
New functions to return 'thing-at-point' for xref backend.
(tex-thingatpt-exclude-chars): New variable to do the same.
(xref-backend-identifier-at-point): New TeX backend method to provide
symbols for processing by xref.
(xref-backend-identifier-completion-table)
(xref-backend-identifier-completion-ignore-case)
(xref-backend-definitions, xref-backend-apropos): Placeholders to
call the standard 'etags' xref backend methods.
(xref-backend-references): Wrapper to call the default xref backend
method, finding as many relevant files as possible and using a bespoke
syntax-propertize-function when required.
(tex--collect-file-extensions, tex-xref-syntax-function): Helper
functions for previous.
(tex-find-references-syntax-table, tex--buffers-list)
(tex--xref-syntax-fun, tex--old-syntax-function): New variables for
the same.
