problem with t-filter/t-vim

Hi Adityam,

I am using the t-filter/t-vim module, and got stuck with two problems with
it.
1. everything works fine if there is only one \definevimtyping declaration.
However, if i declare two of them, as in the following:

%%%%%%%
\definevimtyping[PythonCode][syntax=python]
\definevimtyping[CPPCode][syntax=cpp]

\startPythonCode
... % Code A
\stopPythonCode

\startPythonCode
... % Code B
\stopPythonCode
%%%%%%%

The counter for the temporary files is never incremented. So there is only
"jobname-externalfilter-PythonCode-0.tmp" in the directory.
Consequently, Code B appears twice in the produced PDF, while Code A never
appears.

2. Every line in the Python code becomes a new paragraph in ConTeXt. I
wonder if this could be changed.
I am using \setupwitespace[line], so the spacing between two lines of source
is too large.

I am using the dev/ branch in the github repository.
Thank you very much.

regards,
shenchen

A grouping bug. Does it work with the latest version from the deb branch.

That is by design. Currently, 2context.vim simply adds some markup, and 
the resutant file is read using

\startlines
....
\stoplines

\start-stop-lines converts each line to a paragraph. You can try

\startsetups vim:setups
\setupwhitespace[none]
\stopsetups

\setupvimtyping[setups=vim:setups]

to see if it helps.

Aditya
