To answer my own question:
At 10:39 PM 8/1/2004, I wrote:
There's a nice little problem that arises in LaTeX, of wanting to write a bit of code like the following, to define an environment that passes the contents of the environment to a command as an argument:
\newcommand{\foo}[1]{...} \newenvironment{fooenv}{% \foo\bgroup }{% \egroup }
There's even a nice FAQ entry about this. [1] As it turns out, the amsmath package defines a handy [EMAIL PROTECTED] command that handles collecting the environment body to pass it to a command.
Anyhow, I'm finding myself wanting to do this in ConTeXt, with of course replacing \newenvironment with \definestartstop. Is there by any chance a built-in ConTeXt macro that can do this? Or even things that would make a decent foundation for building such a thing?
The \grabuntil and \processbetween commands, as defined in syst-ext.tex, do exactly what I'm asking for.
If you want to play with low level features, it makes sense to look into:
syst-gen.tex
syst-ext.tex (syst-new.tex)
supp-box.tex
supp-fun.tex
the interfaces of syst/supp modules are sort of 'public' and stable. These modules may also teach some tex tricks -)
