[show-&-tell] ad-hoc adoptations from a different style to another one.

[goyalyashpal]

Prelude

I am using

• a language for interactive terminal sessions (like console or psql)
• style=bw
• and the output is tokenized as Generic.Output

i wanted to make the output tokens from style=bw to appear just like they do in default style, since:

• the output is not differentiated from the CLI in any way in style=bw,
• unlike its distinct light grey color in default style.
• this makes it very hard to read.

If you really want gray comments, you'll have to customize the comment token macro. You'll need something like this in the preamble:

\makeatletter
\appto{\minted@patch@PYGZhy}{%
  \def\PYG@tok@c{\let\PYG@it=\textit\def\PYG@tc##1{\textcolor[rgb]{0.5,0.5,0.5}{##1}}}}
\makeatother

Details

So,

0. i inspected the _minted-* directory of my existing project
   • I saw these terms at line start of .pygtex files \PYG{g+gp} for prompt Generic.Prompt, and \PYG{g+go} before output lines Generic.Output, or sometimes even this \PYG{l+s+s1} before Bye lol Literal + String + ?
   • i noticed that \PYGZ*{} is just like x/html character entities, so, gt >, hy -, bs \, sq ' (single quotes)
1. i created a Minimal working example actually, it was for asking the question, but it immediately led myself to discover the hack
2. i inspected the same _minted-* dir of this MWE and
   • noticed the files bw.pygstyle default.pygstyle *.pygtex
3. i immediately opened both style files and searched for go and found this following line in default.pygstyle defining the grayscale color (all 3 arguments to color of same value)
4. I guarded this inside \makeat* and pasted in my preamble. and voilla, it worked :)

\@namedef{PYG@tok@go}{\def\PYG@tc##1{\textcolor[rgb]{0.44,0.44,0.44}{##1}}}

Cons and Alternates

• i reckon that this will define & overwrite this for all the styles, which may not be desirable in general usecases.
• fortunately, it ain't a problem for me at this very moment.
• i thought about pasting this line verbatim in the bw.pygstyle but it would be very volatile and not very "setup once & forget" method
• i tried makeat inside the \newmintedfile's body, but it didn't compile

but anyhow, What better way of doing this would you suggest? 😃

MWE source

\begin{filecontents}[noheader, overwrite]{./test.mysql}
    mysql-> select * from firstLine;
    +--------------------+
    | Database           |
    +--------------------+
    mysql-> \help contents
    mysql-> \h contents
    You asked for help about help category: "Contents"
\end{filecontents}

\documentclass{article}
\usepackage{minted}

% \makeatletter
% \@namedef{PYG@tok@go}{\def\PYG@tc##1{\textcolor[rgb]{0.44,0.44,0.44}{##1}}}
% \makeatother


\begin{document}

\inputminted[autogobble]{psql}{test.mysql}
\inputminted[autogobble, style=bw]{psql}{test.mysql}

Why not do this on Python side, by defining your own Pygments style, probably based on a builtin style?
