The YAML syntax highlighting in Vim 7.3 isn't great. Putting an apostrophe in a line of text triggers quote highlighting even when there's no quote. The same thing happens in other files sometimes too. I've posted a screenshot below. Is there any way to fix this behavior, or is there a different YAML syntax file I can use that won't trigger this behavior? This occurs in both MacVim and Vim in the Terminal. I'm running v7.3.

Thanks for your help, Kevin

look at your vim7.3 installation directory under syntax/yaml.vim, roughly line 32:

syn region  yamlString      matchgroup=yamlStringDelimiter
                            \ start=+'+ skip=+''+ end=+'+
                            \ contains=yamlSingleEscape

if you throw that out, vim wont try to guess that ' is not the start of a string. the only other way imho would be to change the code so a ' only count as the start of a string, if the preceding character is a whitespace... but if you dont use ' as string-quote anyway, just throw out what i mentioned.

  • for VIM 7.4 you want to find two lines that start with syn region yamlFlowString and comment them out.
