Add an API method for getting cwd (and similar) from config.

[joachim-n]

drush_cwd() has been removed.

I can see there is a cwd() method on the Environment object, but I don't see how to get hold of that from a command.

The Environment object is not available after preflight. It copies any useful information it contains to the configuration object. The cwd if available in config as env.cwd. The best way to get access to the config object is via ConfigAwareInterface / ConfigAwareTrait.

Thanks Greg. Do you think we want/need getter methods for some of the main config items? I think thats a bit more robust that grabbing config by key.

[joachim-n]

Thanks for the quick response.

I found an example of this in PhpCommands now I know what to look for.

Would be good to have a section in the docs on getting things from the environment.

Thought I commented here last week; must not have gotten saved.

Yes, we could create a DrushConfig object with specific accessor methods for folks to use. That would be a good idea.

Accesor methods added today via #3149. See #2954 for docs in interfaces that commands may implement.

For people coming here from Google looking for a quick answer:

$cwd = $this->getConfig()->getContext('environment')->get('env.cwd', getcwd());

Your command class needs to implement ConfigAwareInterface and use ConfigAwareTrait but if you extend DrushCommands then you already have these.
