\inputminted{jacamoproject}{chapter3/code/org_hw3/sag_hw.jcm}

\end{document}

The content of the sag_hw.jcm follow as:

mas sag_hw {                 // the MAS is identified by sag_hw
  agent bob: hwa.asl {  // initial plans for bob are in hwa.asl
    goals: say("Hello World")           // initial goal for bob
  }
}

I am running the file through PDFLaTeX --shell-escape filename.tex, then I got the below error:

I am using MikTeX 2.9 on Windows7 system. I installed Python and pygmentize

Please advise what went wrong in my code…

EDIT

After updating the package minted and Python and Pygmentize, I received the error only for the language \inputminted{jasonagent}{test.asl} only, any advise plase…

Best Answer

The above said issue solved if I run the file in Mac system with the combination of Docker + PDFLaTeX...Thanks to all...

Find how Pygments processes LaTeX input

Go to the lexers folder in the Pygments installation folder. In my case, on Windows, it's in <python_path>/Lib/site-packages/pygments/lexers/; on macOS it is something like /Library/Python/2.7/site-packages/Pygments-2.2.0-py2.7.egg/pygments/lexers/. I haven't tried on Linux. You'll find the path for every lexer in the _mapping.py file.

For TeX/LaTeX, it's the TexLexer class, inside markup.py.

Let's see how it processes a \begin{itemize}. The main "state" is root. When the program finds a \ followed by one or more letters (l. 298), it treats all of it as a Keyword (In our case, that's the \ + begin, that will be printed in bold.), then parses the rest in the command state. The command state checks for square brackets or a star, but doesn't handle curly braces. The {itemize} will then be parsed back in the root state, where it will be printed as a simple text.

Create a custom lexer

If I understood the question correctly, all that's needed is to parse \begin and \end differently than the other commands. Let's create a custom TeX lexer that inherits from the original TexLexer and adds those two specific matches in the root state.

This is what I wrote, in a new Python file. I'm not detailing all of it since it's very context-specific, and the official documentation is precise (see for example here regarding the inheritance).

from pygments.lexer import inherit
from pygments.token import Keyword
from pygments.lexers.markup import TexLexer

__all__ = ['CustomTexLexer']

class CustomTexLexer(TexLexer):
    aliases = ['xtex', 'xlatex']

    tokens = {
        'root': [
            (r'\\begin\{[a-zA-Z\*]+\}', Keyword, 'command'),
            (r'\\end\{[a-zA-Z\*]+\}', Keyword),
            inherit,
        ],
    }

It might also be possible to add it to the same file as TexLexer, but I'm not sure how safe it is. In both case, you need to give new aliases and add the class name to __all__.

Rebuild the lexer mapping

The documentation says to build using this command:

$ make mapfiles

but I couldn't find the corresponding Makefile. The documentation might be outdated here, since the _mapping.py file has been made into a script that can update itself:

$ python _mapping.py

(On macOS this must be executed as sudo to grant writing access in the /Library/ tree.)

Result

We now have two LaTeX lexers at our disposal:

\documentclass{article}

\usepackage{polyglossia}
\setmonofont{Courier New}

\usepackage{minted}
\usemintedstyle{bw}

\begin{document}

Original lexer:
\begin{minted}{latex}
\begin{itemize}[label = {--}]% comment
   \item Text
\end{itemize}
\end{minted}

Custom lexer:
\begin{minted}{xlatex}
\begin{itemize}[label = {--}]% comment
   \item Text
\end{itemize}
\end{minted}

\end{document}

(I had to simplify the preamble because of technical issues, it's unrelated to the current question.)

Output:

Minor update

I updated the custom lexer so that it processes optional arguments of an environment the same way as optional arguments of a macro. It sounded more appropriate at this point. Note that it makes zero difference in the MWE, since the bw class doesn't emphasize the related object, Name.Attribute. Just for show, this is what it looks like with the default style:

[Tex/LaTex] Minted error: Missing pygments error

Solution: For minted to work, pygmentize.exe needs to be added to the Path environment. If using the conda distribution, there could be two versions of the pygmentize.exe.

1) C:\Anaconda3\pkgs\pygments-2.3.1-py37_0\Scripts

2) C:\Anaconda3\Scripts

I added the first directory to my Path environment variables, which resulted in the error mentioned. Removing the first and adding the second, fixed the problem and minted works just fine.

PC needs to be restarted everytime you change environmental variables.
