There appears to be a problem with coloring variables in vim with Ansible yaml files, at least to me

 

Whenever an Ansible variable appears the first double-quote is ignored  and the second takes effect in a way where everything until the next double-quote appears to be a part of the same string.

    ​msg="Backup failed with error {{ syncsync_result.stderr }}"

is a string

    '​msg="Backup failed with error {{ syncsync_result.stderr }}"'

: quotes are not special here, so they *must not* be highlighted as if there was any quoted string. Error with second quote is there because quoted strings as well as flow-style dictionaries are at the top level. If you know how to make `{`, `}` or `"` in the string *not* highlighted (and preferably without performance degradation) you are welcome, I will resend your patch to Bram. I personally have no idea, main problem with plain scalars like this string is that they may contain almost anything, including some valid YAML code that will be parsed as a part of the string by a YAML parser.

Note that in the second case `!=` and `0` also should not be highlighted: `!` is not a tag and `… 0` is not an integer constant.

BTW, also CC the vim-dev or vim-use mailing list. I am not the proficient syntax file author, somebody there may know better.

 

E.g.:

 

But if I add an extra double-quote then coloring goes back to what I expect. Is there some way to fix this? Or do I need a clue?

 

Thanks for all you do.
