| | | | | | * lisp/indent.el (tab-to-tab-stop): * src/indent.c (Findent_to): Mention 'indent-tabs-mode' in doc strings.
* Add a new tree-sitter query predicate 'pred'Yuan Fu2022-12-261-12/+45
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I realized that using an arbitrary function as the predicate in queries is very helpful for some queries I'm writing for python and javascript, and presumably most other languages[1]. Granted, we can already filter out unwanted nodes by using a function instead of a face for the capture name, and (1) determine whether the captured node is valid and (2) fontify that node if it's valid. However, such approach is a bit more cumbersome and more importantly gets in the way of another potential use of the fontification queries: context extraction. For example, I could use the query for the 'variable' feature to get all the variables in a certain region. In this use-case, we want the filtering happen before returning the captured nodes. Besides, the change is relatively small and straightforward: most code are already there, I just need to add some boilerplate. [1] For a code like aa.bb(cc), we want bb to be in function face, because obviously its a function. But for aa.bb, we want bb to be in property face, because it's a property. In the AST, bb is always a property, the difference between the two cases is the enclosing node: in the first case, aa.bb is in a "call_expression" node, indicating that bb is used as a function (a method). So we want a predicate function that checks whether bb is used as a function or a property, and determine whether it should be in function or property face. * doc/lispref/parsing.texi (Pattern Matching): Update manual. * src/treesit.c (Ftreesit_pattern_expand): Handle :pred. (treesit_predicate_capture_name_to_node): A new function extracted from treesit_predicate_capture_name_to_text. (treesit_predicate_capture_name_to_text): Use the newly extracted function. (treesit_predicate_pred): New predicate function. (treesit_eval_predicates): Add new predicate. Also fix a bug: we want to AND the results of each predicate. * test/src/treesit-tests.el (treesit--ert-pred-last-sibling): New helper function. (treesit-query-api): Test #pred predicate.
* Improve handling of tab-bar height.Gregory Heytings2022-12-261-3/+5
| | | | | | * src/xdisp.c (redisplay_tab_bar): When 'auto-resize-tab-bar' is not 'grow-only', also consider the case when the tab-bar height needs to shrink. Fixes bug#60210.
* Simplify last change (bug#60311)Eli Zaretskii2022-12-261-14/+26
| | | | | | | | | | | * src/json.c (json_available_p): Use original code. Always return true for !WINDOWSNT. (ensure_json_available): Now defined only on WINDOWSNT. (Fjson_serialize, Fjson_insert, Fjson_parse_string) (Fjson_parse_buffer): Call ensure_json_available only on WINDOWSNT. * lisp/subr.el (json-available-p): Simplify.

| | | | | | | * src/treesit.c (treesit_recursion_limit): New constant. (treesit_cursor_helper) (Ftreesit_search_subtree) (Ftreesit_induce_sparse_tree): Use the new constant.
* Fix treesit_cursor_helper (bug#60267)Yuan Fu2022-12-241-53/+76
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The cause of that bug is that in a particular parse tree, the node treesit_cursor_helper tries to go to is a missing node, not only is it a missing node, it is the first node of a subtree. So when treesit_cursor_helper follows the algorithm and goes down the tree, it goes down the previous subtree (because that subtree's end = end_pos, because the target node has zero width). o | o--+-o | | +-+ +-+-+ | | | | | o x t o o (We ended up in x when the target is t, because t has zero width.) One way to solve it is to go back up the tree if we are at a leaf node and still haven't matched the target node. That's too ugly and finicky so I resorted to recursion. Now one more functions will return give up (treesit_node_parent) if we are in a werid parse tree that is super deep. But since we already kind of give up on this kind of parse trees (bug#59426), it doesn't really hurt. * src/treesit.c (treesit_cursor_helper_1): New function. (treesit_cursor_helper): Use the new function. Change return type to bool, and accept a cursor pointer. (Ftreesit_node_parent) (Ftreesit_search_subtree) (Ftreesit_search_forward) (Ftreesit_induce_sparse_tree): Use the new signature.
* Fix restart-emacs alarms (Bug#60220)Paul Eggert2022-12-241-0/+1
| | | | | * src/emacs.c (Fkill_emacs): Turn timers off before execing, so that the re-execed Emacs doesn’t get a timer alarm.
* Fix crash after X errorPo Lu2022-12-241-5/+7
| | | | | * src/xdisp.c (redisplay_internal): Catch another crash if gcscrollbars after an X error.
* Fix "C-h k" in recursive minibuffersEli Zaretskii2022-12-231-1/+2
| | | | | | | | * lisp/subr.el (event--posn-at-point): Leave POSN alone if it doesn't have at least 6 members. This follows more faithfully what 'event-start' and 'event-end' did before they started using this function, see commit c1cead89f5f. Call posn-at-point with the minibuffer-window when in the minibuffer. (Bug#60252)
* ; * src/alloc.c (Fmemory_info): Doc fix.Eli Zaretskii2022-12-221-1/+1

* Fix write-region to null device on MS-WindowsEli Zaretskii2022-12-211-3/+7
| | | | | | * src/fileio.c (write_region) [WINDOWSNT]: Ignore EBADF errors from fsync -- this means fsync is not supported for this file. Happens, for example, with the null device. (Bug#59545)
* ; * src/emacs-module.h.in (enum emacs_funcall_exit): Fix typo.Philipp Stephani2022-12-201-1/+1

* Avoid crashes in PGTK build due to signal in 'note_mouse_highlight'Eli Zaretskii2022-12-181-4/+7
| | | | | | | | * src/xdisp.c (string_buffer_position): Make sure the TO argument of 'string_buffer_position_lim' is always inside [BEGV..ZV]. Otherwise 'string_buffer_position_lim' might call 'get-char-property' and friends with invalid position, which will just signal an error and do nothing useful. (Bug#60144)
* Fix MS-Windows build broken by recent treesit.c changesEli Zaretskii2022-12-181-4/+8
| | | | | | | * src/treesit.c (init_treesit_functions, ts_tree_cursor_copy) (ts_tree_cursor_delete): Add boilerplate for using new tree-sitter functions. (ts_node_parent): Delete boilerplate of unused function.
* Use cursor API in treesit-node-parentYuan Fu2022-12-171-6/+13
| | | | | | | | This is the last part of the change that fixes bug#60054. The previous change fixes it for searching functions, this fixes for treesit-node-parent. * src/treesit.c (Ftreesit_node_parent): Use the new cursor API.
* Switch to use cursor API in treesit.cYuan Fu2022-12-171-125/+187
| | | | | | | | | | | | | | | | | | | | | | | | | | | ts_node_parent has bugs (bug#60054), using cursor API avoids that. Tree-sitter's author might remove ts_node_parent in the future, so might as well switch to use cursors now. We are basically reimplementing some of the logic of ts_node_prev_sibling and ts_node_parent in the sibling helper and cursor helper functions. See also https://github.com/tree-sitter/tree-sitter/issues/1992 * src/treesit.c (treesit_traverse_sibling_helper) (treesit_traverse_child_helper) (treesit_traverse_match_predicate): Reimplemented to use the cursor API. (treesit_search_dfs) (treesit_search_forward): Use the new cursor helper functions. (Ftreesit_search_subtree) (Ftreesit_search_forward) (Ftreesit_induce_sparse_tree): Use cursors. * test/src/treesit-tests.el (treesit-search-subtree): New test. (treesit--ert-search-setup): New macro. (treesit-search-forward) (treesit-search-forward-named-only) (treesit-search-backward) (treesit-search-backward-named-only) (treesit-cursor-helper-with-missing-node): New tests.
* Add treesit_assume_true and treesit_cursor_helperYuan Fu2022-12-171-0/+67
| | | | | | | | | This is part 1 of the change to change node API to cursor API. See the second part for more detail. (I splitted the change to make the diff more sane.) * src/treesit.c (treesit_assume_true) (treesit_cursor_helper): New functions.
* Use make-directory handlers uniformlyPaul Eggert2022-12-171-5/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Formerly, the code supported both make-directory and make-directory-internal handlers. This led to confusion and meant than in a few cases (nnmaildir, ido) remote directories could not be used in some cases. Fix this by using only make-directory handlers. Perhaps there used to be a reason for why there were both make-directory and make-directory-internal handlers, but whatever that reason was, it seems to have vanished even before now. There is no longer any need for make-directory-internal handlers, as the few remaining callers that use make-directory-internal do so only when there are no handlers. However, this change keeps the existing make-directory-internal handlers for now, in case this code is ever used in older Emacs versions that still call those handlers. * lisp/gnus/nnmaildir.el (nnmaildir--mkdir): * lisp/ido.el (ido-file-internal): * lisp/net/tramp-smb.el (tramp-smb-handle-make-directory): Use make-directory, not make-directory-internal. * lisp/net/tramp-smb.el (tramp-smb-handle-make-directory-internal): Now obsolete. * src/fileio.c (Fmake_directory_internal): Do not look for or use a make-directory-internal handler. * test/lisp/files-tests.el: (files-tests-file-name-non-special-make-directory-internal): Remove, as this test incorrectly assumes that make-directory-internal must support handlers.
* Fix resizing of mini-windows by 'set-minibuffer-message'Eli Zaretskii2022-12-171-0/+7
| | | | | * src/xdisp.c (redisplay_window): Always resize mini-windows displaying the active minibuffer. (Bug#60015)
* ; Improve wording of 'format' doc stringEli Zaretskii2022-12-161-12/+12
| | | | | * src/editfns.c (Fformat): Use "produce" instead of "print". (Bug#60125)
* Fix SVG scaling (bug#59802)Manuel Giraud2022-12-161-0/+9
| | | | | | | | Fix SVG scaling with librsvg>2.52 and SVG file with only one known dimension. * src/image.c (svg_load_image): Compute a percentage dimension with the other known dimension.
* ; Fix last changes in buffer.cEli Zaretskii2022-12-161-0/+1

* Improve resetting face attributes when looking for suitable fontsEli Zaretskii2022-12-131-29/+52
| | | | | | | | | * src/xfaces.c (syms_of_xfaces)<face-font-lax-matched-attributes>: Change the default value to t. Update doc string. (realize_gui_face): When 'Vface_font_lax_matched_attributes' is t, reset the 3 default font attributes efficiently. Call 'font_maybe_unset_attribute' only if the value is neither nil nor t.

* Revert "Revert "Improve last change to xfaces.c" (05ece1eb8b)"Po Lu2022-12-121-52/+59
| | | | | | | This reverts commit b8d2ec920f37f5d77d32440eefc97dd5e8c2c7dc. Not only does it make debugging Emacs harder for users, that change is unsafe for the Haiku port.
