Editor integration

quiver does not have native editor support. However, for some editors there exist extensions that make working with quiver diagrams more convenient.

Note that the following extensions are third-party, and no guarantees are made regarding their behaviour. It is your responsibility to inspect their behaviour before invoking them.

emacs

The following extension selects the entirety of the LaTeX code associated to a quiver diagram under the cursor and opens a browser window with the corresponding quiver diagram URL, to facilitate convenient editing of existing diagrams.

This extension was contributed by https://github.com/nullst.
