Prompt server password before connection.

How i can configure stage with prompt password to server before connect?

Thank.

Now it's not possible due many reasons: security, parallel execution, ext.

But i think it will be available when implement events in Deployer.

Ok. I now write codes for ask password before connecting. 1-2 hour(s) and i create pull request.

Now, with use PasswordGetter system you can customize logic for gets password.
In get password from Configuration, first checks PasswordGetterInterface instances, and if this it, then calls getPassword($host, $user);

As example, with use base callable (CallablePasswordGetter):

use Deployer\Server\Password\CallablePasswordGetter;

server('production', 'domain.com')
    ->user('user')
    ->password(new CallablePasswordGetter(function ($host, $user){
        return 'some_password';
    }))
    ->stage('production')
    ->env('deploy_path', '/var/www/domain.com');

And with ask password (AskPasswordGetter):

use Deployer\Server\Password\AskPasswordGetter;

server('production', 'domain.com')
    ->user('user')
    ->password(AskPasswordGetter::createLazyGetter())
    ->stage('production')
    ->env('deploy_path', '/var/www/domain.com');

Attention: in configure system, you must use lazy getter, because we should have a access to context for get ouput and input interfaces.

And, if send null password, then AskPasswordGetter will be created automatically.

server('production', 'domain.com')
    ->user('user')
    ->password()
    ->stage('production')
    ->env('deploy_path', '/var/www/domain.com');

Attention: this method not working in parallel... I used this feature only on SeriesExecutor.

Thank.
