Hi Hans,
can you add a second (dummy) argument to \startbuffer.
\setuvalue{\e!start\v!buffer}%
{\begingroup % (3)
\obeylines
- \dosingleempty\buff_start}
+ \dodoubleempty\buff_start}
-\def\buff_start[#1]%
+\def\buff_start[#1][#2]%
{\buff_start_indeed{}{#1}{\e!start\v!buffer}{\e!stop\v!buffer}}
In the following example the space after the right bracket in
“\startbuffer[test]” results in a empty first line in the buffer content and
with a optional second argument this wouldn’t happen.
\starttext
\def\starttest{\grabbufferdata[test][starttest][stoptest]}
\startbuffer[test]
Text in a normal buffer.
\stopbuffer
“\getbufferdata[test]\removeunwantedspaces”
\starttest
Text in a customized buffer.
\stoptest
“\getbufferdata[test]\removeunwantedspaces”
\stoptext
Wolfgang
