I was wondering if it was possible to define a group of modes, such as only one can be used. A MWE is :

\environment myEnvironment
  This is mode A
  This is mode B

which displays "This is mode A" when run with context --mode=modeA file.tex and "This is mode B" when run with context --mode=modeB file.tex

The bonus question is : is there a way to automatically (I mean without manually typing --result=newName) generate different output files (like file_modeA.pdf in the first case and file_modeB.pdf in the second).

  • For the first part see Modes in the Garden. For the second part; no but that is a limitation of TeX. The \jobname is fixed on startup but you can set the jobname from the command line and use a macro to parse for the corresponding mode and enable it. – Henri Menke Sep 22 '16 at 23:05

    If modeA and modeB are never set together, you can just use a single mode and test with \startmode and \startnotmode. – Aditya Sep 22 '16 at 23:23
  • Or, if you want mutually exclusive modes, what is the desired output when I run context --mode=modeA,modeB file.tex? – Aditya Sep 22 '16 at 23:25
  • It is not logical in my context to run it ; the example I was trying to implement was generating a lesson handout in two versions : one for students and one for the teacher. – A. Licari Sep 24 '16 at 7:41

If you don't want to specifiy the mode alongside the result, just use the result name as the mode. For example you can call the example below using

context --result=students test.tex


context --result=teachers test.tex

to enable the eponymous mode. Because enabling the mode takes place at the Lua end you can of course construct much more sophisticated mode-checking constructs.

You can then check for the mode using all the available mode checking commands listed in the Garden. Below I used \doifmode and \doifnotmode but the solution is not restricted to these.

context.enablemode{environment.arguments.result or ""}


\doifmode{students}{for student's eyes}
\doifnotmode{students}{for teacher's eyes}

\doifmode{teachers}{for teacher's eyes}
\doifnotmode{teachers}{for student's eyes}

  • This seems great. I'll try it as soon as I can. – A. Licari Sep 27 '16 at 6:12
  • @A.Licari Did it work? – Henri Menke Oct 1 '16 at 14:22
  • Sorry, I didn't try yet, I had an awful lot of tests to grade -_- – A. Licari Oct 2 '16 at 18:56
