quiver: a modern commutative diagram editor

quiver

quiver is a modern, graphical editor for commutative and pasting diagrams, capable of rendering high-quality diagrams for screen viewing, and exporting to LaTeX via tikz-cd.

Creating and modifying diagrams with quiver is orders of magnitude faster than writing the equivalent LaTeX by hand and, with a little experience, competes with pen-and-paper.

Features & screenshots

quiver features an efficient, intuitive interface for creating complex commutative diagrams and pasting diagrams. It's easy to draw diagrams involving pullbacks and pushouts,

adjunctions,

and higher cells.

3-cell

Object placement is based on a flexible grid that resizes according to the size of the labels.

Arrow styles

There is a wide range of composable arrow styles.

Colours

And full use of colour for labels and arrows.

Screenshot mode

quiver is intended to look good for screenshots, as well as to export LaTeX that looks as close as possible to the original diagram.

Keyboard hints

Diagrams may be created and modified using either the mouse, by clicking and dragging, or using the keyboard, with a complete set of keyboard shortcuts for performing any action.

Export to LaTeX

When you export diagrams to LaTeX, quiver will embed a link to the diagram, which will allow you to return to it later if you decide it needs to be modified, or to share it with others.

Other features

Importing macros and colours

To use custom macros and colours in quiver, create a file containing the definitions, like the following.

\newcommand{\cat}{\mathscr}
\newcommand{\psh}{\widehat}
\newcommand{\smcat}{\mathbb}
\newcommand{\yo}{よ}

Upload the file to a publicly accessible URL (for instance, gist.github.com), and paste the URL for the raw text into the "Macros" input at the bottom of quiver.

Currently, macros may be defined using \newcommand, \newcommand*, \renewcommand, \renewcommand*, \DeclareMathOperator, and \DeclareMathOperator*; and colours may be defined using \definecolor (using the colour modes: rgb, RGB, HTML, gray).

Editor integration

See Editor integration on the quiver wiki.

Building

Run make from the command line, and then open src/index.html in your favourite web browser.

If this fails, you might be using an incompatible version of Make or Bash. In this case, you can manually download the latest release of KaTeX and place it under src/ as src/KaTeX/. If KaTeX has not been given the correct path, you will get an error telling you that KaTeX failed to load.

quiver must be run through localhost. If you have Python installed, an easy solution is to run:

python3 -m http.server

in the quiver src directory and then open localhost:8000 in browser.

If you have any other problems building quiver, open an issue detailing the problem and I'll try to help.
