* Ensure c-ts-mode tests are never stuck (bug#80565)Yuan Fu2 days1-0/+4
| | | | | * test/lisp/progmodes/c-ts-mode-tests.el: Don't prompt for installing cpp grammar when they're not installed.
* Revert "Repair serious breakage in the batch tests."Michael Albinus7 days1-24/+0
| | | | | | | | | | | | | | | | | | | | | | | This reverts commit feac53141577161c32a7a6dfe75399a5ae98a7c1. This patch has deactivated 253 test cases without a sufficient reasoning. Instead it speaks about a shotgun in its commite message. The patch is reverted because - It hasn't been discussed on emacs-devel. It should have, because it is a serious change in our infrastructure (new official tag :nobatch). Any documentation of this change, for example in test/README, is missing. - The proper way to deactivate such tests would have been (skip-when noninteractive) Even better to skip for the respective reasons. - There is no fault report. There is no information about how these tests have failed. Since it hasn't been a problem so far for us, nobody will work on a fix forever.

* Repair serious breakage in the batch tests.Eric S. Raymond14 days1-0/+24
| | | | | | | | | | | | | | There were a bunch of tests that were breaking make check and should never be run in batch mode, because they do things like assuming there is a controlling tty or assuming we can access network services when we can't (e/g. in a CI/CD environment). I have shotgunned this problem by tagging all the failing tests with :nobatch and then changing the default and expensive selectors so make check won't barf all over its shoes. As many of these :nobatch should be individually removed as possible, after upgrading the test harness to mock the environmental stuff they need. Investigate these failures with "make check-nobatch".
* Fix eglot-tests on MacOS (bug#80479)Mattias Engdegård2026-02-241-1/+2
| | | | | | * test/lisp/progmodes/eglot-tests.el (eglot--call-with-fixture): Normalise 'temporary-file-directory' to stave off problems that occur when it contains symlinks, which is common on MacOS.
* Improve m4-mode font lockBasil L. Contovounesios2026-02-222-0/+85
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Emacs 28 started fontifying several 'composite' (non-builtin) GNU M4 macros which, while listed under '(m4) Macro index', are not defined by GNU M4, and are included in its manual for illustrative purposes. These macro keywords range from clearly misleading (e.g., 'example', which the GNU M4 manual explicitly describes as nonexistent), to common in Autoconf's M4sugar layer (e.g., 'm4_quote'), to variations thereof (e.g., 'foreachq'). It is arguably too late to revert all of these additions, so this patch selects a handful to remove, and categorizes the rest; this should make it easier to hide some categories behind a font lock level or user option in the future, if desired. This patch reverts the Emacs 28 addition of 'example', and removes the older 'file', 'line', and 'gnu' macros. GNU M4 renamed 'gnu' to '__gnu__' already in 1990; and I couldn't find references to the other two which exist as '__file__' and '__line__', respectively. The remaining macros are partitioned into three sets: built-in, M4sugar-like, and other (bug#80412). For discussion, see also: https://lists.gnu.org/r/emacs-devel/2025-10/msg00357.html * lisp/progmodes/m4-mode.el (m4-program-options): Remove stale commentary. (m4--macro-list): Remove, replacing with... (m4--builtin, m4--autoconf, m4--composite): ...these new rx definitions. All uses changed. Remove 'example', 'file', 'gnu', and 'line' as keywords. (m4-font-lock-keywords): For consistency with real #-comments, fontify dnl macro with font-lock-comment-delimiter-face, and only the rest of its line with font-lock-comment-face. Fontify argument references with font-lock-variable-use-face rather than font-lock-variable-name-face. Use font lock faces rather than their eponymous but obsolete variables. Remove redundant entries for $@ and $*. Prefer shy regexp groups where applicable. (m4-mode-syntax-table): Quote syntactically special characters. (m4-m4-buffer): DRY using m4-m4-region. (m4-m4-region): Take region bounds as optional arguments, as recommended under '(elisp) The Mark'. Quote shell command. Support non-contiguous regions. (m4-current-defun-name): Recognize m4 backtick in addition to Autoconf bracket. Prefer shy regexp groups where applicable. (m4-mode): Simplify font-lock-defaults. * test/lisp/progmodes/m4-mode-resources/font-lock.m4: * test/lisp/progmodes/m4-mode-tests.el: New test files.
* Use a custom Pdb class in the Python shellLiu Hui2026-02-211-0/+42
| | | | | | | | | | | | | | | | | | | | | | | | The custom Pdb class enables native completion in pdb by wrapping the pdb's native completer. It also makes necessary function definitions like __PYTHON_EL_* available between pdb frames, and enables non-native completion/ffap/eldoc functionalities when debugging inside python modules. * lisp/progmodes/python.el (python-shell-send-setup-code): Fix the separator between python-shell-setup-codes. (python-shell-completion-native-setup): Move common completion setup code ... (python-shell-completion-setup-code): ... here. (python-shell-completion-at-point): Enable native completion for pdb and respect the delimiter of pdb completer. (python-shell-pdb-setup-code): New variable.

* elisp-scope.el: Add variable value specificationsEshel Yaron2026-02-181-0/+5
| | | | | | | | | | | | | | | | | | | | | | | We add a symbol property 'elisp-scope-variable-spec', which holds a specification for the values of a variable with that property. For example, (put 'foo '(symbol . face)) says that the value of variable 'foo' is a face name. This allows elisp-scope.el to analyze forms such as (setq foo 'bar) and (let ((foo 'bar)) ...) more accurately. This is also used for analyzing macros that let-bind (one of) their arguments to a specific special variable, such as 'with-connection-local-application-variables'. We initially add this new property to some common variables. * lisp/emacs-lisp/elisp-scope.el: Add 'elisp-scope-variable-spec' property to 'coding-system-for-read/write' and 'major-mode'. (elisp-scope--variable-spec): New defsubst. (elisp-scope--let-1, elisp-scope-let*, elisp-scope-setq): Use it. * test/lisp/progmodes/elisp-mode-resources/semantic-highlighting.el: Add test form.

(elisp--xref-find-definitions): Fix uses of `elisp--xref-format-extra` accordingly. Improve heuristic to distinguish proper `cl-defgeneric` from implicit ones. (elisp-eldoc-docstring-length-limit) (elisp-eldoc-funcall-with-docstring-length): Remove redundant `:group`. * lisp/cedet/mode-local.el (xref-mode-local-overload): Pass the override symbol rather than its name through `elisp--xref-format-extra`. * test/lisp/progmodes/elisp-mode-tests.el (find-defs-constructor): Adjust test to new text.

* Allow project-vc-ignores to be applied in more casesDmitry Gutov2026-01-011-2/+22
| | | | | | | | | | | | | | | | | | | | Discussed in https://lists.gnu.org/archive/html/emacs-devel/2025-12/msg00903.html. * lisp/progmodes/project.el (project-files) <vc>: Look up the value of 'project-vc-ignores' inside DIR rather than project root. This allows this variable to be applied in external dirs as well. (project-ignores) <vc>: Do likewise. (project--value-in-dir): Ensure that DIR has a trailing slash. The caller might pass the value without slash if produced differently. * test/lisp/progmodes/project-tests.el (project-vc-ignores-in-external-directory): New test. (project-vc-supports-files-in-subdirectory): Update the test, considering the subtle change in behavior: the directory DIR directly includes a .dir-locals.el which sets project-vc-ignores, which wasn't previously applied because it wasn't set in the root.

* ; Fix semantic highlighting in presence of shorthandsEshel Yaron2025-10-212-1/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | So far, 'scope-elisp-analyze-form' would disable 'read-symbol-shorthands' while reading a source form in order to obtain the "original" length of symbols and pass that length to the callback called for each analyzed symbol. However, 'scope-elisp-analyze-form' could report an incorrect length when a symbol was written with redundant escaping (e.g. 'f\oo'). Moreover, disabling 'read-symbol-shorthands' breaks macro-expansion during analysis, because macros may expect "expanded" symbols, without shorthands. In this commit we address these issues by leaving 'scope-elisp-analyze-form' enabled (so we get expended symbols for macro-expansion) and recovering the original length lazily in the callback, if needed, by going to the beginning of the symbol and searching forward for its end. * lisp/emacs-lisp/elisp-scope.el (elisp-scope--report): Replace LEN argument with SYM, the analyzed symbol itself. Adapt all callers. (elisp-scope-analyze-form): Cease let-binding 'read-symbol-shorthands' to nil while reading. Wrap analysis in 'save-excursion' when reading from current buffer. Update docstring. * lisp/progmodes/elisp-mode.el (elisp-local-references) (elisp-fontify-symbol): Obtain symbol length from buffer. * test/lisp/progmodes/elisp-mode-resources/semantic-highlighting.el: Add test that incorporates 'read-symbol-shorthands'. * test/lisp/progmodes/elisp-mode-tests.el (elisp-test-font-lock): Set up 'read-symbol-shorthands' in test file.

* Eglot: escape literal % characters in URIsSteven Allen2025-08-301-0/+4
| | | | | | | | | | | | | | | Escape literal % characters in Eglot URIs Otherwise, a literal % in a file-name will be interpreted (by the language server) as if it were a part of a percent-encoded sequence. See Bug#78984 for context on why `url-path-allowed-chars' cannot be changed to escape literal % characters. * lisp/progmodes/eglot.el (eglot--uri-path-allowed-chars): Escape %, remove the redundant variable definition. * test/lisp/progmodes/eglot-tests.el (eglot-test-path-to-uri-escape): test it.

| | | | | | | | | * lisp/progmodes/lua-ts-mode.el (lua-ts--comment-font-lock): Apply 'font-lock-comment-delimiter-face' to the entire span of initial dashes. In particular, this improves the appearance of LuaCATS and EmmyLua style annotations which use "---". * test/lisp/progmodes/lua-ts-mode-resources/font-lock.lua: Add tests. (Bug#79258)

* ; cperl-mode.el: Indent labels only in code (Bug#79271)Harald Jörg2025-08-221-0/+22
| | | | | | | | | * lisp/progmodes/cperl-mode.el (cperl-indent-line): Make sure that labels are indented in code only * test/lisp/progmodes/cperl-mode-resources/cperl-indents.erts: Two new testcases for non-indentable "labels" in a regex pattern and a qw list
* ; cperl-mode.el: Fix fontification error with signaturesHarald Jörg2025-08-222-1/+8
| | | | | | | | | | | | | | | This fixes the second issue in Bug#79269. * lisp/progmodes/cperl-mode.el (cperl-init-faces): Move handling of signatures with initializers from the "anchor" to the "anchored" matcher * test/lisp/progmodes/cperl-mode-resources/proto-and-attrs.pl (sub_7): Test case for Bug#79269, wrong face report * test/lisp/progmodes/cperl-mode-tests.el (cperl-test-fontify-attrs-and-signatures): Make sure that the test catches sub_7 for Bug#79269
* rust-ts-mode: handle invalid rust syntax without signalingSteven Allen2025-08-212-0/+14
| | | | | | | | | | | | | | Don't signal an error when encountering invalid rust syntax. Without this patch, invalid rust code would prevent a chunk of the buffer from being highlighted (bug#79272). * lisp/progmodes/rust-ts-mode.el (rust-ts-mode--fontify-scope): (rust-ts-mode--fontify-pattern): Avoid calling `string-match-p' on nil when a node is missing a parent. * test/lisp/progmodes/rust-ts-mode-resources/font-lock-no-parent.rs: Rust file that reproduces the issue. * test/lisp/progmodes/rust-ts-mode-tests.el: Test case to reproduce the issue.
