Prints the signals of your application: the actions that emit each signal, and the listeners that react to it.

$ mix ash.signals
$ mix ash.signals MyApp.Shop.Signals
$ mix ash.signals --format mermaid --output signals.mmd

Pass signal modules to only print their signals.

Listeners are found wherever they are defined. Emitters are found in the resources of the domains in your :ash_domains config, and in resources that listen to signals.

Command line options

• --format - Can be set to one of either:
  • text - A list of each signal's emitters and listeners. This is the default.
  • mermaid - A Mermaid flowchart.
  • md - A Mermaid flowchart in a markdown code block.
  • svg, pdf or png - An image of the Mermaid flowchart. Requires --output, and the Mermaid CLI. See https://github.com/mermaid-js/mermaid-cli
• --output - Writes to the given file, instead of printing.
