help on def & buffer

[-- Attachment #1.1: Type: text/plain, Size: 545 bytes --]

Dear List,

please help me with my problem here ....

I - probably naively - tried the following:
------------------------

\starttext


\def\Buffer#1#2

{

\startbuffer[#1]

\input #2

\stopbuffer

}

\Buffer{bla}{knuth}


\stoptext

-------------------------


Context gives me the following error on this:


tex error > tex error on line 9 in file
C:/Users/emargraf/Documents/buffer.tex: ! Undefined control sequence



\Buffer ...startbuffer [#1] \input #2 \stopbuffer

l.9 \Buffer{bla}{knuth}


-----------------------


Kind regards

Erik

\startbuffer .. \stopbuffer is parsed special

so use:

\def\Buffer#1#2
   {\setbuffer[#1]{\input #2\relax}}

\Buffer{bla}{knuth}

but i'm not sure what you gain here as it will still input tufte each time

Than you Hans!
My plan is simply to use the output of a sagemath run in this way. A run
should produce
several files containing TeX code. I only wanted to shorten the
\startbuffer \input ... \stopbuffer
sequence. Maybe this (including sagemath output) could be done differently,
but this was
the first (and only ;-)) idea I came up with.

kind regards
Erik

I don't know sagemath but I assume this is a use case for Aditya's
filter module¹. It's included in the distribution.

Ups, didn't expect that ...  ;-)
Thanks Wolfgang! Actually your version works, Hans' version does not ...
(could try them only now)

Kind regards
