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
----
Compilation fails with:
"
tex error > tex error on line 0 in file : ! Emergency stop
<*> cont-yes.mkiv
<empty file>
*** (job aborted, no legal \end found)
"
How to make the sample work?
Best regards,
Lukas

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.

Hello Aditya,
thanks for the code, I'll try something like that.
Best regards,
Lukas

modes are like buffers ... don't wrap them in macros
(using names like \b \e is a bad idea anyway)

I used \doifmode and friends for selection of mode dependent code.
