One of my project needed roles.
Needed permissions and authorizations were not complex enough to require additional plugins or extensions, I only wanted to deal with Yii. So, let's see how I did, one may find useful insights too for his/her case.
For one of my projects I needed an interactive console command in Yii 1, i.e. the one that is gathering all information from user in an interactive mode (a serie of questions and answers displayed directly in the console), ignoring command-line arguments at all.
Using a version control system, like Git, is nice. However, when building an extension from scratch and loading it via Composer, it adds a lot of pain in the butt steps. You have to commit your changes, update composer to pull them over, then notice there is an error, fix, commit, update. repeat.. I don't want all my baby steps under Git. Sure, I could edit my commit history, but c'mon. Just let me code! I will put it under version control once I get a baseline created. This guide will show you how to setup your composer.json to load a local directory (everything inside, live). You make a change, save the file, refresh the page, boom.
