Vim module - different settings for inline and block code

Vim module - different settings for inline and block code

Hi,

I need different settings for code in inline and block mode. See the
following example:

\usemodule [vim]
\definetextbackground [C] [location=text]
\definevimtyping [C]
  [syntax=c,
   before={\starttextbackground[C]},
   after=\stoptextbackground,
   margin=2em]

\starttext

This is C: \inlineC{int foo();}. \blank
\startC
int foo(){
  return 0;
}
\stopC

\stoptext

Inline code needs “location=text”, block code on the other hand
needs “location=paragraph” as text background setting. Sure, I can
create two environments “Cinline” and “Cblock”, but that feels
clumsy.

What's the proper way to set up different backgrounds for inline
and block code?

Marco

You can try this (untested):

\definetextbackground[InlineBackground][location=text]
\definetextbackground[DisplayBackground][location=paragraph]

\definevimytping
  [C]
  […,
   before={\ifhmode\startInlineBackground\else\startDisplayBackground\fi},
   after={\ifhmode\stopInlineBackground\else\stopDisplayBackground\fi},
   …]

You could also ask Aditya to use different keys for display (e.g. before/aftter)
and inline (e.g. left/right) code blocks.

That's a good idea and it seems to work.

That's not necessary. I think your solution is clean enough.

Thanks Wolfgang.

The test doesn’t work when you use \inlineC at the beginning of a paragraph because
TeX it at this moment still in vertical mode and you have to add a \dontleavehmode
to force horizontal mode.

<example>
\def\TestMode
  {\ifhmode
     \bold{Horizontal Mode}%
   \else
     \bold{Vertical Mode}%
   \fi}

\starttext

\TestMode\ Inline \TestMode

\dontleavehmode\TestMode\ Inline \TestMode

\stoptext
</example>

That's a nice suggestion. I have implemented it in the dev version of the 
filter module: https://github.com/adityam/filter/tree/dev but haven't 
tested it beyond a simple test case: 
https://github.com/adityam/filter/blob/dev/tests/25-before-left.tex

I'll do more thorough tests and a proper release later.
