Hi all,
I noticed that \doifinstring produces quite strange output if a command
follows immediately (or with any amount of spaces) after the substring
I am searching for:
-------------------------------------MWE
\starttext
\def\xxx{asdf \bf Z:\bf asdf} % strange
\def\xxx{asdf \bf Z: \bf asdf} % strange
\def\xxx{asdf \bf Z:: \bf asdf} % OK
\def\xxx{asdf \bf Z: text \bf asdf} % OK
\def\xxx{asdf \bf Z:{} \bf asdf} % OK
\doifinstring{Z:}{\xxx}{yes!}
\stoptext
----------------------------------OUTPUT
fbf@yes!
fbf@yes!
yes!
yes!
yes!
----------------------------------------
If I insert another character, text or {} between them
(with or without spaces), all is ok.
I would like to ask what is the cause of this behavior and how to
use the \doifinstring to prevent the "fbf@" on the output.
Best wishes
Tomáš

btw, you can prevent it by using lmtx

Hi Hans,
ok, thank you, lmtx is a good way.
