Also one might highlight special keywords used in combination with :=: https://docs.typo3.org/typo3cms/CoreApiReference/ApiOverview/TypoScriptSyntax/Syntax/TypoScriptSyntax.html#value-modifications-the-operator

Hello Daniel,

thank you very much for the pull request. I test it and try to follow the improvements.

Let's review the Object unsetting sign ">" first. You say it is not highlighted. I find the entry:

syntax match tsLineOperator "\v\>\s*$" contained containedin=tsSingleline

This should match it and classify it as tsLineOperator, which is mapped to the vim Operator highlighting class.

highlight link tsLineOperator Operator

This regular expression above assumes, that it is not followed by other text within the same line. It would not be matched, if you place a comment within the same line.

The expression says:

1. use \v very magic regular expressions (similar to perl regular expressions).
2. match the ">" sign
3. allow whitespace or none
4. then the end of line

I am a little out of exercise with typoscript. Maybe you like to provide a small file with all examples, that should be highlighted. As a common test case. Does not need to be real TS, just a concentrate of all features.

I suggest the path:

vim.typoscript/example.ts

As a separate pull request, I could merge it first.
