Ruby Script: List of Method Names in Files
Today, I began work on a task in which I’ll manually check whether several Ruby on Rails controllers and their actions are still used or not.
There are several controller files, so to remain organized, I opted to list up all of the relevant ones. In doing so, I found myself wanting to have a list of their actions (each associated with its controller) as well.
One thing led to another, and I ended up creating this Ruby script that lists up four things:
- directory
- controller filename
- line number on which the action is defined
- action name (excluding
def, comments, etc.)
The list is in a simple CSV format for easy transferral into Excel.
Sample output:
Directory,Filename,Line,Method
app/controllers,home_controller.rb,2,index
app/controllers,home_controller.rb,4,about_me
(There were far more results at work, of course.)
This saved me a lot of time and tedium, and it should make the task far more manageable.
