Nope, sorry. It smells like something to do with expansion; all I know about expansion is that it causes problems (sometimes) when there are macros inside macros. But it might not be expansion. I hope that helps, but it probably doesn't. ;-) --Sietse

Hello,

interesting trick; however, it doesn't work when used inside a macro:

---- \definebuffer[Hidden]

\def\WWW{ \startHidden DDD \stopHidden }

\starttext AAA

\startHidden BBB \stopHidden

\WWW \stoptext ----

Any idea?

TIA.

Best regards,

Lukas

is it possible to define a start-stop command to hide text within?

Something like:

\definestartstop[Hidden][before=\starthiding,after=\stophiding]

Just define any buffer, and don't call \getbuffer[mybuffer]. Buffers are not typeset, by default, until you get them. The below is shamelessly adapted from Hans's \starthiding (which already exists):

\definebuffer[Hidden] % uncomment the below to turn this into a non-hiding buffer. % \setupbuffer[Hidden][after={\getbuffer[Hidden]}]

jjjj

\startHidden asdf asdf \stopHidden

Cheers, Sietse

Hello, thanks H&W - both solutions are useful.
