The only piece not provided here is the kdp.cls file, which helps optimize things for self publishing on Amazon. This can be found at github.com/JenniferMack/latex-kdp.
The value added is just in gathering a few different things. The advantages over another template from the book class might be
- KDP class for adjusting page sizes.
- Adding images at the beginning of each new part in the book with the epigraph package.
- Use of the lstlistings package for inline code and code blocks.
- Some custom helper commands like
\code{}or\link{}{}that simplify other commands.
Some more things in the style files could be removed for the example included. I have experimented with \marginpar and \marginnote to label code blocks with the filenames. While not demonstrated here, my solution has been to use (*@\margintext{filename}@*) inside the code blocks, where (*@ and @*) are escape characters. \margintext is a custom command that uses \marginnote with some extra text formatting. Previously, I tried to use \marginpar to force all labels to the right and rotate them 90 degrees, but I was never happy with the results.
