Having compiled a new complex document utilizing minted I recognized the following line there:

for compatibility with earlier versionsfor compatibility with earlier versions

At this point I do not want to give a MWE, because the same issue happens with minted.dtx (compiling with TL17/pre and its packages). That's in the generated pdf (to be seen also here):

minted compatibility

Just for protocol the output of \listfiles for minted.dtx:

Interestingly enough I have this problem in two dtx files I try to compile, but I cannot build a MWE which could produces this error. Does anyone know where this error comes from?

Update: As egreg pointed out it is a problem with doc and pygstyle files. By modifying my pygstyle (vs in my case) I could achieve that only

for compatibility with earlier versions

is printed. But where does the second one come from?

If you locally reset the catcode of % then the pygments example works as intended

For example, changing the first minted example in minted.dtx from

 % \inputminted[gobble=2,frame=lines]{latex}{minted.doc.out}


 % {\catcode`\%=14 \inputminted[gobble=2,frame=lines]{latex}{minted.doc.out}}

Running the .dtx file generates (via a call to pygmentize) some .pygstyle files, which contain, at the end,

% for compatibility with earlier versions

What happens is that the % is ignored because we're compiling a .dtx file with doc conventions.

These files should have, at the beginning, something like


and, at the end,


but this is out of our control, because it should be done by pygmentize in latex.py.

Note that % characters inside a minted environment or files loaded with \inputminted will disappear.

A different way to cope with this would be removing the


from the setting in \fvset and adding a fake guard around the construction:

% For example:
% \iffalse
% \fi
{\catcode`\%=14 \inputminted[gobble=2,frame=lines]{latex}{minted.doc.out}}
% \iffalse
% \fi
% will highlight a piece of code in a chosen language.
% The appearance can be customized with a number of options and color schemes.

(I added a % to the code just to show it will appear as expected.)

Credit to David Carlisle for the second part of the trick.

  • Thanks for the explanation. By modifying the pygstyle I use I could remove one of the messages. But where's the second? – TeXnician May 6 '17 at 11:09
  • @TeXnician There are two files that are read; in the example I made they are default-pyg-prefix.pygstyle and default.pygstyle – egreg May 6 '17 at 11:15
  • Okay, so there's probably no way to really use minted in a dtx file. I guess pythontex would have the same problem, wouldn't it? – TeXnician May 6 '17 at 11:19
  • @TeXnician you should be able to use minted anyway, you just need to locally revert some of the doc-specific catcodes while reading the pygments generated files. – David Carlisle May 6 '17 at 11:53
  • @DavidCarlisle Would you be so kind and post an answer containing an example (could give you instead of egreg the tick)? – TeXnician May 6 '17 at 11:59
