Quick question: Is \startcolorscheme... \stopcolorscheme (still)
supported by t-vim?
It is supposed to work. If it doesn't, then it is a bug. Could you
provide a complete MWE.
Please find a MWE at the bottom of this post.
The expected behaviour is that the keyword `function` in the JavaScript
snippet and `foobar` in the Ruby snippet should be colored and in
italics, as comments are. The respective Vim highlight groups are
`javaScriptFunction` and `rubyMethodName`, which both resolve to
`Function`.
The reason that there is no highlighting is because the generated `.vimout`
does not contain any `\SYN[rubyMethodName]` or `\SYN[javaScriptFunction]` for
the following reason:
Vim has the concept of a hierarchy of names for the syntax highlighting
regions. For example, $VIMRUNTIME/syntax/ruby.rb contains the following lines:
hi def link rubyMethodName rubyFunction
hi def link rubyFunction Function
So, `rubyMethodName` maps to `rubyFunction`, which in turn maps to `Function`.
Now, a vim colorscheme first checks if a highlighting style is available for
`rubyMethodName`; if not it tries `rubyFunction`; and if not it tries
`Function`.
Although something similar might have been possible in 2context.vim, I follow
the `TOHtml` function of vim, and simply created a single tag for each syntax
highlighting element, which in this case is `Function`. So, there is no tag
generated for `rubyMethodName` and that is why changing the syntaxhighlight for
that doesn't change anything.
Now, as I was looking into this, I noticed that `foobar` gets mapped to
`Identifier` rather than `Function`. I am not sure why that is happening and I
will look into that.
