In the documentation for the listings package it says:

literate = [*]<replacement item>. . .<replacement item>

First note that there are no commas between the items. Each item consists of three arguments: {<replace>}{<replacement text>}{<length>}. <replace> is the original character sequence. Instead of printing these characters, we use <replacement text>, which takes the width of <length> characters in the output.

[...]

The optional star indicates that literate replacements should not be made in strings, comments, and other delimited text.

Problem:

I want to define my own language with listings but can not use the above mentioned star, as it gives me a compiling error. The following (I tried [] brackets too) does not work even though it works without the star *:

literate = *{-}{{{\color{purple}-}}}{1}

Please note that this is just a excerpt of a bigger list of literates, which shouldn't change the usage however.


MWE:

This is probably not minimal, but I wanted to keep it as close to the original as possible so one could see other errors. It is actually compiling now. It has lost its colors in the non-comment parts though, moreover it puts completely arbitrary quotation marks (this also occurs in the original). (original Python& special characters)

You have to use a different literate for starred ones:

literate=
*{-}{{{\color{ipython_purple}-}}}1,

If you add more literates after this one (without the star) they will behave as if they were starred. For example

literate=
*{-}{{{\color{ipython_purple}-}}}1
 {?}{{{\color{ipython_purple}?}}}1,

Also, the quotes at the beginning of the listing are due to the fact that there's a missing comma after

morestring=[s]{u"""}{"""}

Note that I've added two ? in your listing just to show the effect, remove them as well as {?}{{{\color{ipython_purple}?}}}1 in the second literate.

  • Thanks! You were absolutely right to add ?, actually even more are necessary. Mar 29, 2015 at 21:59
  • @hillbilly You're welcome. Mar 30, 2015 at 4:52
  • Not quite sure, if someone will read this, but I tried this and when specifying a new literate (for the starred ones), the old literate is gone (therefore if I take your mwe above, and add some ä to the source code, it will not compile since the literate conversion to \"a is not done anymore :/

  • I suggest modifying such that basicstyle=\scriptsize\ttfamily so that the numeric characters are in the same font as the rest of the text. You may also want to \usepackage{upquote} to get normal single-quotes instead of curly quotes in the output.
