* Add binary format specifications '%b' and '%B'Jacob S. Gordon2025-12-221-2/+81

* Change tree-sitter query predicate names (bug#79687)Yuan Fu2025-11-021-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Latest tree-sitter library throws a syntax error if the predicate names in a query don't end with question mark. So we made the following change: :equal changed to :eq? :match changed to :match? :pred changed to :pred? Old names are transparently converted to new names when expanding patterns. :match predicate can now take the regexp and the node in any order: it'll figure out which is which automatically. This way it works with current Emacs convention (regexp first), as well as tree-sitter's match convention (regexp second). * doc/lispref/parsing.texi (Pattern Matching): Update manuel to use new predicate names. * src/treesit.c: (Ftreesit_pattern_expand): (Ftreesit_query_expand): (treesit_predicate_match): (treesit_eval_predicates): (syms_of_treesit): Use new predicate names. * test/src/treesit-tests.el (treesit-query-api): Update test.

* Respect keymaps in buffer text for clicks on displayed stringsSpencer Baugh2025-10-181-5/+16
| | | | | | | | | | | | | | | | | | | When clicking on a string displayed by a display property, also look at the text properties of the underlying buffer text for keymaps, not just the displayed string. The displayed string takes precedence over the buffer text, but it doesn't replace it. Also, we should use the buffer's local map even for clicks on the mode line. (Otherwise, what's the point of the <mode-line> event?) * src/keymap.c (Fcurrent_active_maps): Consider displayed string, then buffer text, then fall back to local map. (Bug#79505) * test/src/keymap-tests.el (keymap-test-keymaps-for-non-buffer-positions): Add more tests.

* Allow creating a pipe process without a bufferSpencer Baugh2025-10-111-0/+6
| | | | | | | | | | | | | Previously, even passing :buffer nil to make-pipe-process would create a buffer. Now, if you explicitly call (make-pipe-process :buffer nil), it will create a pipe process without a buffer, just like all the other process creation functions. * src/process.c (Fmake_pipe_process): Check for explicit :buffer nil and don't make a buffer. (bug#79596) * doc/lispref/processes.texi (Asynchronous Processes): Update. * test/src/process-tests.el (process-test-make-pipe-process-no-buffer): Add test.

* Ignore keymaps at point for positions outside the bufferSpencer Baugh2025-09-091-0/+27
| | | | | | | | | | | | | | | | Correct a few edge cases where we used the keymaps at point when looking up keymaps for an event position which is outside the current buffer. Namely: - Clicking on a part of the mode line which is after the end of mode-line-format produces an event with non-nil posn-area but nil posn-string. - Even if posn-string doesn't have a local keymap, we should still ignore the keymaps at point if posn-string is non-nil. * src/keymap.c (Fcurrent_active_maps): Ignore keymaps at point for more positions outside the buffer. (bug#76620)
* Disallow string data resizing (bug#79784)Mattias Engdegård2025-08-242-7/+20
| | | | | | | | | | | | | | | | | | | | | | | | | Only allow string mutation that is certain not to require string data to be resized and reallocated: writing bytes into a unibyte string, and changing ASCII to ASCII in a multibyte string. This ensures that mutation will never transform a unibyte string to multibyte, that the size of a string in bytes never changes, and that the byte offsets of characters remain the same. Most importantly, it removes a long-standing obstacle to reform of string representation and allow for future performance improvements. * src/data.c (Faset): Disallow resizing string mutation. * src/fns.c (clear_string_char_byte_cache): * src/alloc.c (resize_string_data): Remove. * test/src/data-tests.el (data-aset-string): New test. * test/lisp/subr-tests.el (subr--subst-char-in-string): Skip error cases. * test/src/alloc-tests.el (aset-nbytes-change): Remove test that is no longer relevant. * doc/lispref/strings.texi (Modifying Strings): * doc/lispref/sequences.texi (Array Functions): * doc/lispref/text.texi (Substitution): Update manual. * etc/NEWS: Announce.

| | | | | | | | | | | | | | | | | | | | | | We use the current parsing position instead.

Copied from comments in treesit.c: Technically we had to send tree-sitter the line and column position of each edit. But in practice we just send it dummy values, because tree-sitter doesn't use it for parsing and mostly just carries the line and column positions around and return it when e.g. reporting node positions[1]. This has been working fine until we encountered grammars that actually utilizes the line and column information for parsing (Haskell)[2]. [1] https://github.com/tree-sitter/tree-sitter/issues/445 [2] https://github.com/tree-sitter/tree-sitter/issues/4001 So now we have to keep track of line and column positions and pass valid values to tree-sitter. (It adds quite some complexity, but only linearly; one can ignore all the linecol stuff when trying to understand treesit code and then come back to it later.) Eli convinced me to disable tracking by default, and only enable it for languages that needs it. So the buffer starts out not tracking linecol. And when a parser is created, if the language is in treesit-languages-require-line-column-tracking, we enable tracking in the buffer, and enable tracking for the parser. To simplify things, once a buffer starts tracking linecol, it never disables tracking, even if parsers that need tracking are all deleted; and for parsers, tracking is determined at creation time, if it starts out tracking/non-tracking, it stays that way, regardless of later changes to treesit-languages-require-line-column-tracking. To make calculating line/column positons fast, we store linecol caches for begv, point, and zv in the buffer (buf->ts_linecol_cache_xxx); and in the parser object, we store linecol cache for visible beg/end of that parser. In buffer editing functions, we need the linecol for start/old_end/new_end, those can be calculated by scanning newlines (treesit_linecol_of_pos) from the buffer point cache, which should be always near the point. And we usually set the calculated linecol of new_end back to the buffer point cache. We also need to calculate linecol for the visible_beg/end for each parser, and linecol for the buffer's begv/zv, these positions are usually far from point, so we have caches for all of them (in either the parser object or the buffer). These positions are far from point, so it's inefficient to scan newlines from point to there to get up-to-date linecol for them; but in the same time, because they're far and outside the changed region, we can calculate their change in line and column number by simply counting how much newlines are added/removed in the changed region (compute_new_linecol_by_change). * doc/lispref/parsing.texi (Using Parser): Mention line-column tracking in manual. * etc/NEWS: Add news. * lisp/treesit.el: (treesit-languages-need-line-column-tracking): New variable. * src/buffer.c: Include treesit.h (for TREESIT_EMPTY_LINECOL).

* Don't escape "." in `prin1' when followed by a letterSpencer Baugh2025-04-281-2/+4
| | | | | | | | | | | | | | | | | | | Among other users, let-alist widely uses symbols which start with a ".". Make those symbols print more nicely by tweaking the escaping rules in print_object to not escape a leading "." followed by a letter. This is a conservative change to avoid constraining future lexer changes. This is a followup to 637dde4aba921435f78d0de769ad74c4f3230aa6, which removed some unnecessary escaping of "." and "?" when printing symbols in prin1. (Actually, if we always escaped "?" (which was the case before 637dde4aba92) then "." only ever needs to be escaped when string_to_number returns non-nil. So 637dde4aba92 could have just dropped the escaping of "." with no other changes, if it didn't also remove escaping of "?") * src/print.c (print_object): Don't escape "." as the first character in a symbol if followed by a letter. (bug#77656). * test/src/print-tests.el (test-dots): Update for new behavior.
