Category Theory for Programmers

Category Theory for Programmers

Direct link: category-theory-for-programmers.pdf
(Latest release: v0.1, September 2017)

This is an unofficial PDF version of "Category Theory for Programmers" by Bartosz Milewski, converted from his blogpost series.

Conversion is done by scraping the blog with Mercury Web Parser to get a clean HTML content, modifying and tweaking with Beautiful Soup, finally, converting to LaTeX with Pandoc. See scraper.py for additional information.

Please report any formatting/content issues, or better yet, send a PR!

Building

For macOS Users: The Inconsolata LGC and Linux Libertine fonts are not included in MacTex. You need to install them separately. Download the Inconsolata LGC fonts here and the Linux Libertine fonts here. To install the fonts system-wide, move all the downloaded .otf files into the /Library/Fonts folder. After completing these tasks, continue with the instructions below.

The src directory contains the LaTeX sources. To recompile the book, go there and enter:

$ make

The file preamble.tex contains all the configuration and style declarations.

Chances for successful compilation are increased if you have almost complete installation of recent TeX Live distribution (the PDF here is compiled with 2017 release). The needed OpenType fonts must be installed in the operating system. You also need Inkscape to recreate image PDFs from SVGs.

To remove all the generated PDFs and auxiliary files in the whole src tree:

$ make clean-all

Tip: you can use a utility like entr to run a command after any *.tex file changes, e.g.:

$ ls **/*.tex | entr make

This will monitor all the *.tex files for changes, and will execute the make command if any of them changes. This speeds up development significantly, as you can freely modify any of the files, and get almost instant feedback!
