Moreover, if you comment line line 126 of `2context.vim`
"let s:id = synIDtrans (s:id)
[If you make a local copy of 2context.vim, then you need to run the
file with `--mode=dev-vim` to ensure that the local copy is used]
Then the ruby example generates the following file:
\SYNBOL{}\SYN[rubyComment]{# Ruby program listing}\SYNEOL{}
\SYNBOL{}\SYN[rubyDefine]{def}\SYN[rubyMethodBlock]{
}\SYN[rubyMethodName]{foobar}\SYNEOL{}
\SYNBOL{}\SYN[rubyMethodBlock]{
print(}\SYN[rubyStringDelimiter]{"}\SYN[rubyString]{Hello
World}\SYN[rubyStringDelimiter]{"}\SYN[rubyMethodBlock]{)}\SYNEOL{}
\SYNBOL{}\SYN[rubyDefine]{end}\SYNEOL{}
So, if you are willing to define wrappers for all ruby syntax blocks,
then I can provide a configuration option so that `2context` does not
apply that line.
That might provide a finer control over the highlighting, but the main
issue here seems to be that the generated file has Identifier instead of
Function, Special instead of Delimiter and Constant instead of String.
Looking at 2context.vim, AFAICS s:id_name seems computed correctly.
Maybe, the script does not set the appropriate filetype?
filetype is set correctly (since we get `ruby....` options), but something
weird is happening even with 2html.vim. Here is a minimal example:
```test.rb
# Ruby program listing
def foobar
print("Hello World")
end
```
Run:
vim -u NONE -c "syntax manual" -c "set syntax=ruby" -c "source
/usr/share/nvim/runtime/syntax/2html.vim" -c "wqa" test.rb
gives
```test.rb.html
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"
"http://www.w3.org/TR/html4/strict.dtd";>
<html>
<head>
...
</head>
<body>
<pre id='vimCodeElement'>
<span class="Comment"># Ruby program listing</span>
<span class="PreProc">def</span> <span class="Identifier">foobar</span>
print(<span class="Special">"</span><span class="Constant">Hello World</span><span
class="Special">"</span>)
<span class="PreProc">end</span>
</pre>
</body>
</html>
<!-- vim: set foldmethod=manual : -->
```
which is similar to what 2context.vim gets. If I source tohtml.vim or
2context.vim from an existing vim session, then the tags are correct. I have
not been able to figure out why this is happening.
