I would like to distribute my own lexer with latex sources. I use:

\begin{minted}{myLexer.py:MyLexerClassName -x}

which works fine. But when I use czech babel, compilation fails with error: "The control sequence marked < to be read again > should not appear between \csname and \endcsname."

Full code:



\begin{minted}{myLexer.py:MyLexerClassName -x}


When it works (one of the choices):

  1. If I use system lexer
  2. If I don't use babel package
  3. If I use other language (I tried magyar)

Ultimately I would like to use this in beamer environment, but beamer is not the source of the problem.

  • Welcome to TeX.Stackexchange! Just a guess: maybe it could help to switch off some czech specific \shorthandoff, but I don't know which shortshands are used in czech, neither can I test without your lexer. – user36296 Oct 27 '18 at 13:26
