From 172cc23d88585dd7520726c2ebbba4ed7639e348 Mon Sep 17 00:00:00 2001 From: zeertzjq Date: Sat, 17 Aug 2024 07:09:39 +0800 Subject: vim-patch:d164f2a: runtime(vim): Update base-syntax, improve :let-heredoc highlighting (#30069) The end marker must appear on line of its own without any trailing whitespace. Whitespace is incorrectly allowed before all end markers. Limiting this only to heredocs where "trim" was specified, and with the correct indent, is currently an intractable problem given that contained syntax groups (in this case :let) cannot be limited to start patterns. Highlight interpolated expressions when "eval" is specified. cloess: vim/vim#15511 https://github.com/vim/vim/commit/d164f2a521f8e52e587727657fb1c19e9a25f32a Co-authored-by: Doug Kearns --- runtime/syntax/vim.vim | 13 ++++++++++--- 1 file changed, 10 insertions(+), 3 deletions(-) (limited to 'runtime') diff --git a/runtime/syntax/vim.vim b/runtime/syntax/vim.vim index 8dd72d76e5..57516dfa61 100644 --- a/runtime/syntax/vim.vim +++ b/runtime/syntax/vim.vim @@ -433,11 +433,12 @@ syn match vimEscape contained "\\\o\{1,3}\|\\[xX]\x\{1,2}\|\\u\x\{1,4}\|\\U\x\{1 syn match vimEscape contained "\\<" contains=vimNotation syn match vimEscape contained "\\<\*[^>]*>\=>" -syn region vimString oneline start=+$'+ skip=+''+ end=+'+ contains=vimStringInterpolationBrace,vimStringInterpolationExpr -syn region vimString oneline start=+$"+ end=+"+ contains=@vimStringGroup,vimStringInterpolationBrace,vimStringInterpolationExpr +syn region vimString oneline start=+$'+ skip=+''+ end=+'+ contains=@vimStringInterpolation +syn region vimString oneline start=+$"+ end=+"+ contains=@vimStringGroup,@vimStringInterpolation syn region vimStringInterpolationExpr oneline contained matchgroup=vimSep start=+{+ end=+}+ contains=@vimExprList syn match vimStringInterpolationBrace contained "{{" syn match vimStringInterpolationBrace contained "}}" +syn cluster vimStringInterpolation contains=vimStringInterpolationExpr,vimStringInterpolationBrace " Substitutions: {{{2 " ============= @@ -517,7 +518,13 @@ VimL syn keyword vimUnlet unl[et] skipwhite nextgroup=vimUnletBang,vimUnletVars syn match vimUnletBang contained "!" skipwhite nextgroup=vimUnletVars syn region vimUnletVars contained start="$\I\|\h" skip="\n\s*\\" end="$" end="|" contains=vimVar,vimEnvvar,vimContinue,vimString,vimNumber -VimFoldh syn region vimLetHereDoc matchgroup=vimLetHereDocStart start='=<<\s*\%(trim\s\+\%(eval\s\+\)\=\|eval\s\+\%(trim\s\+\)\=\)\=\z(\L\S*\)' matchgroup=vimLetHereDocStop end='^\s*\z1\s*$' extend +" Note: This incorrectly matches end markers with leading whitespace even if +" "trim" was not specified.
