Link to this function cmd(command, options \\ [], callback) View Source

An implementation of the command callback that is shared across different shells.

Link to this function printable_app_name() View Source

Returns the printable app name.

This function returns the current application name but only if the application name should be printed.

Calling this function automatically toggles its value to false until the current project is re-entered. The goal is to exactly avoid printing the application name multiple times.
