rebar_autotdd

A rebar3 plugin for auto running compile on source file change reloading modules in the shell. Based on rebar3_auto_plugin.

Prerequisite

On Linux you need to install inotify-tools.

Use

Add the plugin only to your user local rebar config in ~/.config/rebar3/rebar.config:

{plugins, [rebar3_autotdd]}.

If you add it to your project rebar.config, it will get unloaded each time compilation occurs, thus breaking it.

Then run

    $ rebar3 compile

Then just call your plugin directly in an existing application:

$ rebar3 autotdd
