[fluxsauce]

I'd like to add https://github.com/fluxsauce/site_audit/tree/8.x-2.x integration.

To clarify the scope; allow contrib commands to be added that aren't part of a Drupal installation.

[Jaesin]

So you are saying console should search in ~/.drupal_console/modules-enabled (Or something like that) for drupal modules with console commands.

[fluxsauce]

@Jaesin I was thinking something similar to Drush commands, which can be installed in places like ~/.drush/commands.

Ideas:

• ~/.drupal_console/contrib
• ~/.drupal_console/commands
• ~/.drupal_console/vendor

Thoughts?

[jmolivas]

The command discovery mechanism search for command classes at DrupalConsole + DrupalCore + Custom/Contrib modules.

We can update the code to search for commands classes ouside of a custom/contrib module at a common place like you mentioned, I was thinking to use ~/.console/src/Command/.

[jmolivas]

For commands inside a contrib module command classes must be created at MODULE_NAME/src/Command if the command is a generator then the generator class must be created at MODULE_NAME/src/Generator

As the webprofiler module:

@Jaesin & @fluxsauce I will close and add a new issue on the documentation project repository.
