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. |
