Re: [NTG-context] New module: simplesteps.

Thank you both, Philipp and Wolfgang, I've updated the wiki. Wolfgang wrote:

You have to give the name of begin command because context has to know it when buffers are nested (I will a explanation about this in another thread).

Ah, I was wondering about that. Yes, I'd be interested in the background explanation. Cheers, Sietse On Sat, Dec 15, 2012 at 1:38 PM, Wolfgang Schuster wrote:

\begingroup \grabbufferdata[simplesteps][startframe][stopframe]% }

With the \grabbufferdata command the content beginning from \startframe until \stopframe is stored in a buffer with the name “simplesteps”.

(1) What does the \begingroup do? I could not find a \endgroup in the patch, nor in the module code.

(2) I've approximately documented grabbufferdata here: http://wiki.contextgarden.net/Command/grabbufferdata But when I tried to write a minimal example, I couldn't get it to compile.

%% begin example \grabbufferdata[mybuffer][thisisthestart][thisistheend] \thisisthestart My friend, you would not tell with such high zest To children ardent for some desparate glory, The old Lie: Dulce et decorum est Pro patria mori. \thisistheend

\typebuffer[mybuffer] %% end example

What am I doing wrong? And is the description I put on the wiki correct?

The \grabbufferdata command reads only all text until the end command (e.g. \thisistheend) but the beginning command for the buffer (e.g. thisisthestart) has to be defined by the user.

You have to give the name of begin command because context has to know it when buffers are nested (I will a explanation about this in another thread).

\starttext

\def\thisisthestart {\grabbufferdata[mybuffer][thisisthestart][thisistheend]}

\thisisthestart My friend, you would not tell with such high zest To children ardent for some desparate glory, The old Lie: Dulce et decorum est Pro patria mori. \thisistheend

\typebuffer[mybuffer]

\stoptext
