When I work with Azure DevOps pipeline files (yaml), I don't get any syntax highlighting in script or bash blocks:

Azure DevOps pipeline with yaml syntax highlighting

That's why I have installed inkarkat/vim-SyntaxRange and configured it to recognize bash syntax between bash:/script: and displayName/condition.

~/.vim/after/syntax/yaml/SyntaxInclude.vim:

call SyntaxRange#Include('^\ *- \(script\|bash\): |', 'condition\|displayName', 'bash')

Now it looks like this:

Azure DevOps pipeline with SyntaxInclude plugin

The script block looks great now, except that pipeline template variables (${{ ... }}) are highlighted as syntax errors.

Can I somehow overrule the syntax highlighting of ${{ ... }}?

    Not sure how inkarkat/vim-SyntaxRange works, but you can usually add new :syntax commands in various ways (files, autocommands, by hand, etc.)

  • I tried :syntax match parens "\v\{\{.{-}\}\}", :highlight parens ctermfg=red guifg=red, but with no effect.

  • It still has no effect, when I put these lines into ~/.vim/after/syntax/sh/double-braces.vim. But these commands work after :set syntax=.

Reset to default

This fixes it:

~/.vim/after/syntax/yaml/SyntaxInclude.vim:

call SyntaxRange#Include('^\ *- \(script\|bash\): |', 'condition\|displayName', 'bash')

" Allow template variables ...

" ... in YAML
syntax match doublebraces "\v\$\{\{.{-}\}\}" containedin=ALL
highlight doublebraces ctermfg=blue guifg=blue

syntax match braces "\v\$\{[0-9A-Za-z_.]{-}\}" containedin=ALL
highlight braces ctermfg=green guifg=green

syntax match parens "\v\$\([0-9A-Za-z_.]{-}\)" containedin=ALL
highlight parens ctermfg=green guifg=green

" ... in script block
syntax match shDerefSimple "\${{.*}}" nextgroup=@shNoZSList

UPDATE: The first solution didn't not work well for some files. The updated configuration is not yet perfect but quite usable.
