General ⇒ Defining new languages for listings package

[ebigunso]

The Array color is not bluegreen already... Try without the

Code: Select all

morekeywords = [5]{boolean(},

line, maybe it's the unclosed parenthesis that causes problem... (Here, everything is black, the pdf has no colors)

hmm, weird. Seems there are more to this pLaTeX/LaTeX compatibility issue. Unforeseen problems really make things harder to solve

Try to define the keywords like this:

Code: Select all

\lstset{classoffset=0,
morekeywords={one,three,five},keywordstyle=\color{red},
classoffset=1,
morekeywords={two,four,six},keywordstyle=\color{blue},
classoffset=0}% restore default

Try to define the keywords like this:

Code: Select all

\lstset{classoffset=0,
morekeywords={one,three,five},keywordstyle=\color{red},
classoffset=1,
morekeywords={two,four,six},keywordstyle=\color{blue},
classoffset=0}% restore default

Tried. Doesn't work.

The bug comes from the parenthesis... This works without, and doesn't with :

Code: Select all

  basicstyle=\footnotesize,

  showstringspaces=false,
  showtabs=false,                  
  tabsize=2,
  morekeywords = {boolean},
  morekeywords = [2]{myboolean}, % HERE : add remove the parenthesis
  keywordstyle = [2]\color{codegreen}
}

  n = len(genl2)
  M = None #to become the incidence matrix
  VT = np.zeros((n*m,1), int)  #dummy variable
  
  #compute the bitwise xor matrix
  M1 = bitxormatrix(genl1)
  M2 = np.triu(bitxormatrix(genl2),1)

  else:
  M = np.concatenate((M, VT), 1)
  
  VT = np.zeros((n*m,1), int)
  
  return M

  boolean b;
  myboolean c;
\end{lstlisting}

\end{document}

[thomasb]

Here is a possible solution :

Code: Select all

\begin{lstlisting}[escapechar=!] % here : the ! is declared an escape character
  boolean b;
  myboolean c;
  !\color{codegreen}{boolean}! c; % boolean will be green, but shorter...
\end{lstlisting}

and keep the rest of the code.

Another solution is to define another style, mystyleforbooleanonly, and switch when you need an orange "boolean". The line count will be reset to zero, but it can be set with the firstnumber keyword of the lstlisting environment : firstnumber=last.
And, there is a name keyword : \begin{lstlisting}[name=asdf, ... to force a name to the lstlisting environement ; and then join them together with the \vspace{-\baselineskip} command :

Code: Select all

\begin{lstlisting}
  boolean b;
\end{lstlisting}
\vspace{-\baselineskip}
\begin{lstlisting}[firstnumber=last,name=asdf]
  boolean b;
\end{lstlisting}
\vspace{-\baselineskip}
\begin{lstlisting}[name=asdf]
  myboolean c;
\end{lstlisting}
\vspace{-\baselineskip}
\begin{lstlisting}[escapechar=!,name=asdf]
  !\color{codegreen}{boolean}! c;
\end{lstlisting}

Seems like a good enough solution, but on Overleaf, it gives the following error "Package Listings Warning: Text dropped after begin of listing on input line 94." and the part of interest is not shown in the final result.
Also it seems a bit too complicated to use every time I want to color function names blue.

So, to me it seems the other solution with the escapechar works quite well. Not automatic, but still simple enough to use. Thanks for all the help you gave me, it was a big help!

I'll try it out and come back if anything else goes wrong.

[thomasb]

Thanks too, you taught me a lot with your listing things, come back whenever you want...
