Hello Aditya,

thanks for the code, I'll try something like that.

Best regards,

Lukas

Hello,

I'm struggling with using modes to make a part of the text conditional.

Here is my code:

----
\def\b#1{\startmode[#1]}
\def\e{\stopmode}

% \enablemode[100] % For optional usage

\starttext
A
\b{100} % Should be start of some conditional text from here ...
  B
\e % ... to here
\stoptext

Modes don't work that way. You can do something like this:

\define[1]\bbb
     {\doifnotmode{#1}
         {\grabbufferdata[dummy][bbb][eee]}}

\let\eee\relax

\enablemode[100]

\starttext
A

\bbb{100}
   Inside mode 100
\eee

\bbb{101}
   Inside mode 101
\eee

\stoptext


Depending on the actual use case, there might be simpler ways.

Aditya
