buffer broken?

buffer broken?

[Hans van der Meer]

[-- Attachment #1.1: Type: text/plain, Size: 491 bytes --]

Something must have been changed with buffers between the versions:
ConTeXt  ver: 2011.11.29 18:47 MKIV  fmt: 2011.12.31
and
ConTeXt  ver: 2012.01.09 10:08 MKIV  fmt: 2012.1.11

Formerly this was ok:
\startbuffer[abc]
whatever
\stopbuffer

Now I get: ! Missing } inserted.

Because running this in isolation goes without a problem, I suspect the change has to do with the project structure in which I use the buffer. But again, it worked in the past.

Does it works with
\setbuffer[abc]
whatever
\endbuffer
?

It works with these macros, yes. Thanks.

But is \setbuffer..\endbuffer something new? I do not see it on the Reference page of the wiki. Also it doesn't seem in line with ConTeXt's regular naming scheme of \startsomething..\stopsomething.
Can you give somewhat more information, for examle what is the difference between \setbuffer and \startbuffer?

Well, start/stopbuffer should work... and Hans said that it will be fixed
in the next beta.

The problems seems to be a missing \endgroup

\setuvalue{\e!start\v!buffer}%
  {\bgroup
   \obeylines
   \dosingleempty\buff_start}

\def\buff_start[#1]%
  {\buff_start_indeed{}{#1}{\e!start\v!buffer}{\e!stop\v!buffer}}

\def\buff_start_indeed#1#2#3#4% \donothing needed !
  {\normalexpanded{\buff_pickup{#2}{#3}{#4}{}{\buff_stop{#4}}}}

Perhaps it should be
\def\buff_start[#1]%
  {\buff_start_indeed{}{#1}{\e!start\v!buffer}{\e!stop\v!buffer}\egroup}

No, it’s a old command but not very useful for a user.

The original source for the reference pages didn’t provide a way to describe the syntax for \setbuffer but there are also many commands which are undocumented.

\setbuffer can’t be nested like \startbuffer and not a command which should be used in a document. It’s useful for internal use when one write macros where the regular buffer environment can’t be used.
