* 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.

* 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 "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/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)

* 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

* Fix SVG scaling (bug#59802)Manuel Giraud2022-12-161-0/+9

| | | | | | | This reverts commit b8d2ec920f37f5d77d32440eefc97dd5e8c2c7dc. Not only does it make debugging Emacs harder for users, that change is unsafe for the Haiku port.

* Unset the weight/slant/width in the spec when realizing a fontGregory Heytings2022-12-101-2/+58
| | | | | | | | | | | | | | | | | | | | | | | | | | | Between commits bf0d3f76dc (2014) and 6b1ed2f2c9 (2022), realize_gui_face called font_load_for_lface with an empty or partly emptied font spec, i.e. it ignored a part of its attrs argument. The rationale given in bug#17973, which led to bf0d3f76dc, is not clear. However, 6b1ed2f2c9, which passes the full font spec to font_load_for_lface and font_find_for_lface, leads to suboptimal font choices, for example when the font chosen for the default face has a weight, slant or width that is not supported by other available fonts on the system, such as 'medium' or 'heavy'. If these attributes are not unset here, the call to font_list_entities in font_find_for_lface arbitrarily limits the candidate font list to those that are perfect matches for these attributes, which means that the scoring mechanism is bypassed. Note that the size attribute in spec is also unset, in font_find_for_lface. Also allow unsetting the other attributes, for debugging purposes. * src/xfaces.c (realize_gui_face): Unset the weight, slant and width of the font spec. Fixes bug#57555 and bug#59347. (syms_of_xfaces): New variable 'realize-gui-face-ignored-spec-attributes'.
