Hello,

In addition to \startbuffer \stopbuffer it would be nice to have \startappendbuffer \stopappendbuffer.

I see that the lua function buffer.append() exists but I have not worked-out how to add this functionality cleanly as conTeXt macros. I imagine that this might be quite trivial for our TeX programming experts... (for once, a [useful?] suggestion that in the end will not entail many hours of work? :)

\startbuffer[a] Line 1 \stopbuffer

\startbuffer[b] Line 2 \stopbuffer

\starttext

\startlines \getbuffer[a,b] \stoplines

\stoptext

Thank you Wolfgang, this is useful. However, it would still be helpful to be able to generically add to a buffer without having to rename a new one. Shouldn't be very difficult but I did not find that anything like this already exists. I often think this way when I teach, adding steps to an example while repeating the previous steps. \startbuffer[a] Line 1 \stopbuffer \getbuffer[a] \startaddtobuffer[a] Line 2 \stopaddtobuffer \getbuffer[a] Alan
