This is an unofficial PDF version of "Category Theory for Programmers" by Bartosz Milewski, converted from his blogpost series (with permission!)

---

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

Chances for successful compilation are increased if you have almost complete installation of recent TeX Live 2017 distribution (the PDF here is compiled with 2017 release). The needed OpenType fonts must be installed in the operating system. In addition, pygments for Python must be installed as well.

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

$ make

Upon successful compilation, the files will be placed in the out directory next to src.

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