**strid** is a tool to generate string diagrams for inclusion in
LaTeX documents. These diagrams are often used in category theory as a
convenient way to represent 2-cells in 2-categories. It has a syntax
which is inspired
of Xy-matrix
(but dual diagrams are generated). It is written
in OCaml and freely distributed under
the GPL license.

The released versions of strid can be found on the downloads page. Hackers may also be interested in getting the code from github.

You can read the pdf manual.
