Two questions about buffers

Two questions about buffers

[Marcin Borkowski]

Hello,

I have two questions concerning buffers.

1. What is the difference between \grabbufferdata and \dostartbuffer?

2. I wanted to use buffers to define my own "environment" (as Wolfgang
suggested to me a few days ago).  However, there's a problem with
\baselineskip; here is an example:

\starttext

\def\startMyEnv{\dostartbuffer[MyEnv][startMyEnv][stopMyEnv]}
\def\stopMyEnv{{\tfxx\getbuffer[MyEnv]\par}}

\input tufte

\startMyEnv
  \input knuth
\stopMyEnv

\input tufte

\stoptext

Am I doing something wrong here?

TIA

\tfxx just switches a font and does not adapt the baseline

use \switchtobodyfont[small] or \tfxx\setupinterlinespace instead

You can use the annotation module for your environment.

\usemodule[annotation]

\defineannotation[MyEnv][style=\txx]

\starttext

\input tufte

\startMyEnv
 \input knuth
\stopMyEnv

\input tufte

\stoptext

There is no difference, \grabbufferdata is just the new name for \dostartbuffer in MkIV and it’s recommended to use the name name.
