runtime(java): Manage circularity for every :syn-included syntax file Commit: https://github.com/vim/vim/commit/60310a4b2630a4d3bb0b6da9bc03061ecfbac9ee Author: Aliaksei Budavei <0x000c70@gmail.com> Date: Fri Oct 4 20:25:05 2024 +0200 runtime(java): Manage circularity for every :syn-included syntax file With "g:markdown_fenced_languages" defined and "java" added to its list, a circular dependency between the Markdown and Java syntax files will be made. To break it, no Markdown documentation comments will be recognised in fenced blocks in Markdown files; in order to view Java source files, "java" must be removed from "g:markdown_fenced_languages", and this task can be automated as follows. 1) Add to "~/.after/ftplugin/java.vim": ------------------------------------------------------------ if exists("g:markdown_fenced_languages") && \ !(exists("g:java_ignore_javadoc") || \ exists("g:java_ignore_markdown")) let s:idx = index(g:markdown_fenced_languages, 'java') if s:idx > -1 call remove(g:markdown_fenced_languages, s:idx) endif unlet s:idx endif ------------------------------------------------------------ 2) Optionally add to "~/.after/ftplugin/markdown.vim": ------------------------------------------------------------ if exists("g:markdown_fenced_languages") && \ index(g:markdown_fenced_languages, 'java') < 0 call add(g:markdown_fenced_languages, 'java') endif ------------------------------------------------------------ (Make sure that the above snippets appear in the files under the "ftplugin" NOT "syntax" directory.) Finally, unless the new version of the syntax file is made available from "$VIMRUNTIME" (and from "~/.vim/syntax" if necessary), OTHER discoverable file versions will be used whose behaviour may interfere with this fix. related: #15740 closes: #15796 Signed-off-by: Aliaksei Budavei <0x000c70@gmail.com> Signed-off-by: Christian Brabandt <cb@256bit.org>
