From adcd9360dfefc7b1e1edb0e86df460e074991c8d Mon Sep 17 00:00:00 2001 From: Christian Clason Date: Mon, 23 Dec 2024 11:12:58 +0100 Subject: vim-patch:4ce1cb5: runtime(graphql): contribute vim-graphql to Vim core Contribute the core of my vim-graphql project (ftplugin, indent, syntax) to the Vim project. This replaces the basic ftplugin support that was already in the runtime with a more complete set of filetype settings. I can assume maintainership for all of these files. I'll continue to maintain the higher-level embedded filetype support separately (in vim-graphql) for now, because it's fairly complex, but we can consider integrating that code directly into vim later. runtime files use the MIT license. closes: vim/vim#16273 https://github.com/vim/vim/commit/4ce1cb5bf1dc507224792543d8e56e6ab431a2b5 Co-authored-by: Jon Parise --- runtime/indent/graphql.vim | 92 ++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 92 insertions(+) create mode 100644 runtime/indent/graphql.vim (limited to 'runtime/indent/graphql.vim') diff --git a/runtime/indent/graphql.vim b/runtime/indent/graphql.vim new file mode 100644 index 0000000000..dc0769b9a8 --- /dev/null +++ b/runtime/indent/graphql.vim @@ -0,0 +1,92 @@ +" Vim indent file +" Language: graphql +" Maintainer: Jon Parise +" Filenames: *.graphql *.graphqls *.gql +" URL: https://github.com/jparise/vim-graphql +" License: MIT +" Last Change: 2024 Dec 21 + +" Set our local options if indentation hasn't already been set up. +" This generally means we've been detected as the primary filetype. +if !exists('b:did_indent') + setlocal autoindent + setlocal nocindent + setlocal nolisp + setlocal nosmartindent + + setlocal indentexpr=GetGraphQLIndent() + setlocal indentkeys=0{,0},0),0[,0],0#,!^F,o,O + + let b:did_indent = 1 +endif + +" If our indentation function already exists, we have nothing more to do. +if exists('*GetGraphQLIndent') + finish +endif + +let s:cpo_save = &cpoptions +set cpoptions&vim + +" searchpair() skip expression that matches in comments and strings. +let s:pair_skip_expr = + \ 'synIDattr(synID(line("."), col("."), 0), "name") =~?
