We have seen that plugins can be very helpful in many situations, so it's time for us to develop our own! Before starting, we need to know a few things; the first is an idea for a plugin. In our case, we will develop a Ruby on Rails plugin that will help us identify relationships between ActiveRecord models. ActiveRecord models can define relationships with other ActiveRecord models that are defined across different files, creating a plugin that will automatically open all the related files. This plugin can be very helpful for a Rails developer.
It is also important to have the Sublime Text API open simultaneously. It can be found at http://www.sublimetext.com/docs/3/api_reference.html. Lets not forget a name for our plugin! In our case, we will call the plugin RelationsFinder. The Default Packages folder is full of useful open source plugins with code snippets and examples.
