ascii2svg

ascii2svg is a command-line tool to draw SVG graphs from simple ASCII descriptions.

This is an alpha release. It works, but needs tests and customization options.

Install

npm install -g ascii2svg

Usage

ascii2svg [--html] <input> <output>

It’ll read on stdin if <input> is -; and write on stdout if <output> is -.

Options:

• --html: wrap the resulting SVG in an HTML page so that you can open it in your browser.

Tips

• You can use browser for quick previews: echo -e "a->b\nb->c" | ascii2svg --html - - | browser

Formats

ASCII

This is the simplest format. Each line represents one or more links using ASCII arrows. Nodes labels can be any string without hyphen nor newline.

Example:

a -> b -> c
b -> d

The direction of the arrows is not important; you can use -, <- or -> with as many hyphens as you want.

The example above creates a graph of 4 nodes with three edges connecting b to all other nodes.
