This is the official home of the development repository for the tqft library for LaTeX. This package is for drawing cobordism diagrams, as typified in topological quantum field theory (tqft).

The current published version can be found on CTAN and the documentation is there as a PDF.

To use the most recent version, download the file tqft_code.dtx and then run tex tqft_code.dtx to generate the library file. The documentation is in tqft.tex.

The TQFT package has two main versions (both are created by tqft_code.dtx and so both are available in CTAN):

• Version 1: the original version defined the diagrams using nodes. To use this version, use \usepackage{tqft} in your preamble. This version will not get new features, but I'll fix bugs (if I can). On CTAN, this was frozen at v2.1 (though it hasn't been updated since v1.1).
• Version 2: the most recent version defines the diagrams using pics. To use this version, use \usetikzlibrary{tqft} in your preamble. This is the recommended version and the one that is maintained.
