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


Building

The best way to build the book is using the Nix package manager. After installing Nix, type nix-shell in the root directory of the project. This will download all the needed dependencies and tools to build the book (TeXLive, required fonts and packages, Pygments theme for syntax highligting, etc.)

When the download is complete, and you're prompted with a shell, use the instructions below to build the book.

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

$ make

To build the Scala edition, type:

$ make scala

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.
