Useful LaTeX presets for pretty printing code.

How to use code_presets.tex

1. Create a new .tex file for your project.
2. Copy %%-----DOCUMENT section into your file. Everything else will go into the $DOCUMENT CONTENTS HERE$ section.
3. Select files, which you want to format. Currently supported formats are makefile, C code and README files.
   • Copy %%-----C, %%-----README or %%-----MAKEFILE section into your document.
   • Replace $FILE CONTENTS HERE$ with the contents of your file.
4. Optional:
   • If you want your code sections to be labled with filenames, add a %%-----FILENAME section before the code section you are labeling. And replace $FILENAME HERE$ with full path to your file.
   • Split your document into pages by adding \newpage between code sections.
   • Split one file into pages by inserting %%-----PAGEBREAK section inside code sections. (It looks much better than the default paging, trust me.)
   • In the %%------README section, you can highlight words in bold with <:words in bold:> and italicize words with <|words in italics|>.
   • Add extra keywords (like size_t or FILE) for highlighting, by adding the %%-----MOREKW section before the code section and replacing $EXTRA KEYWORDS HERE$ with the keywords you want highlighted. (Comma seperated list. Sadly, no spaces are allowed in keywords)

Notes.

The paging is set up in such a way, that exactly 80 characters fit horizontally. If your listing looks ugly, because of hard wrapping lines/ugly alignment, please consider refactoring your code, so it does fit into 80 characters.

Installing TeX and the packages used in this preset, may be quite bothersome. As an alternative, I suggest using an online latex editor/compiler. Not all of them work. It is almost guaranteed that overleaf will work.
