Hi,
Pablo and I were discussing possibilities for code examples.
We’d like to copy a code example to a comment (annotation) because
it’s easier to copy from there, esp. if line numbers are involved.
The example tries 3 ways, but only the first works, i.e. using a named
buffer and calling it by name.
I don’t understand why the version with a defined buffer doesn’t work.
Isn’t “CodeExample” the name of the buffer?
In the third case, I tried to hook the comment in typing; here I don’t
know the name of the buffer. I tried \currenttype and \currentbuffer,
but that didn’t work.
"""
\setupinteraction[state=start,]
% this works:
\protected\def\CodeBuffer[#1]{%
\comment[location=inmargin,space=yes,buffer=#1]{}%
\typebuffer[#1]\blank\getbuffer[#1]}
% comment is empty:
\definebuffer[CodeExample]
\define\stopCodeExample{%
\comment[buffer=CodeExample,location=inmargin,space=yes,color=orange]{}%
\comment[buffer=\thedefinedbuffer{CodeExample},...]{}
Thank you!
Do you also know a solution how to hook the comment into a typing
environment, for this case:
"""
% comment is empty, what should be the name of the buffer?
\protected\def\CodeComment#1{%
\comment[location=inmargin,space=yes,buffer=#1]{}}
\setuptyping[TEX][before=\CodeComment] % or after or whatever
"""
Typing uses buffers internally, but I don’t understand enough of the code.
