Moreover, if you comment line line 126 of `2context.vim`

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]{

\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:
Figured out what is happening. From `:he syntax`
"The names marked with * are the preferred groups; the others are minor groups.
For the preferred groups, the "syntax.vim" file contains default highlighting.
The minor groups are linked to the preferred groups, so they get the same
highlighting. You can override these defaults by using ":highlight" commands
after sourcing the "syntax.vim" file."
All three `Function`, `Delimiter` and `String` are minor groups, so they get
mapped to the preferred groups, which are `Identifier`, `Special`, and
`Constant`, respectively. Most colorschemes define colors for minor groups as
well, but since we are not loading any colorscheme, the minor groups are mapped
to preferred groups, and we only get the preferred groups in the output.
Now that I know what is happening, it is relatively easy to fix.
```
\definecolor[colorone] [r=0.251, g=0.349, b=0.322]
\definecolor[colortwo] [r=0.612, g=0.608, b=0.478]
\definecolor[colorthree] [r=1.0, g=0.827, b=0.576]
\definecolor[colorfour] [r=1.0, g=0.592, b=0.310]
\definecolor[colorfive] [r=0.960, g=0.310, b=0.161]
\definecolor[nearlywhite] [r=0.988, g=0.988, b=0.988]
\setupinteraction[state=start]
\setupcolors[textcolor=colorone]

\usemodule[vim]

\stopvimrc
\startcolorscheme[oceansunset]
\definesyntaxgroup[Comment] [color={colorfive},style=italic]
\definesyntaxgroup[Function][color={colorfive},style=italic]
\stopcolorscheme
\definevimtyping[RUBY]
[
syntax=ruby,
alternative=oceansunset,
escape=on, %NOTE, the comma was missing in your test file
% Without the comma, the option is not set
extras=minor-groups,
]
\starttext
\startRUBY
# Ruby program listing
def foobar
print("Hello World")
end
\stopRUBY
\stoptext
```
Since I already map the minor groups to preferred groups in `t-vim`, I think
that a good compromise is to enable the minor groups by default. I can do that
by adding statements similar to those above in `2context.vim`. This will not
have any visual impact on any existing code, but will allow those who want to
tweak the highlighting of minor groups to define their own syntax highlighting.
