Help on \dostartbuffer needed

Help on \dostartbuffer needed

[Antoine Cailliau]

Hi,

I'm trying to deal with \dostartbuffer.

I found an old message on the ML about \dostartbuffer
http://www.mail-archive.com/ntg-context@ntg.nl/msg08222.html
and its is pretty what I want except that I do not know how can I get
access to the buffer :)

For instance,
\def\startLST[#1]%
    {\def\stopLST{End of #1}%
     \dostartbuffer[LST][startLST][stopLST]}

  \starttext
  \startLST[whatever]
  bla bla
  \stopLST
  alb alb
  \stoptext

will print End of whateveralb alb. I just want to get the content blabla in \stopLST.

I guess, it should not be hard :)

Antoine

Sorry for the noise

This time, it is not working, and I do not have any idea why.

\defineenumeration[ENUM][]
\definebuffer[Entity,before=\startENUM,after=\stopENUM]

\starttext

\startEntity
\input tufte
\stopEntity

\stoptext

fails with 

! Missing \endcsname inserted.

\startEntity
...
\stopEntity

\getEntity

or

\def\startEntity
   {\dostartbuffer[Entity][startEntity][stopEntity]}

\def\stopEntity
   {\startENUM
    \getbuffer[Entity]
    \stopENUM}
