[luatex] Computer code listings in attractive labeled boxes

[lloyd at writersglen.com]

Hi Siep,

Many thanks for your response.

Unfortunately, the listings package doesn't give us quite what we need. It provides formatting and token lighting. We need to mark arbitrary sequences of code to emphasize code changes from previous listings.

I've attached an examples of what we have so far, both screen shots and LaTex code:

listing_9.2.png shows our original attempt at styling code lists.
listing_3.8.png shows our more recent attempt
listings.txt shows code for both approaches

Our problem is that we need to convert several hundred such listings into a visually attractive style.

Best wishes,

Lloyd

But they were rather ugly. My co-author found a way to make them more attractive, but the process is kludgy and inordinately time-consuming.

Did you try to export your book to LaTeX? When using LaTeX (or
pdflatex or lualatex) directly, you can use e.g. the listings
package, which supports syntax highlighting and can typeset code
from external files.
