Deprecool

A static ruby code analyzer to find your deprecated code!

For any developer who has ever ignored a gem's warning and then ran into an error when they went to update

Usage

Add to your gemfile: gem 'deprecool' Or directly gem install deprecool

Then you can run deprecool in the command line to get:

Commands:
  deprecool list                     # Display which finders are used in this version
  deprecool scan [PATHS]             # Scan files or directories for known deprecations
  deprecool version                  # Print the deprecool version

Scan

deprecool scan has several options that can be passed, or it can be run in a folder with a Gemfile.lock to automatically look for deprecations based on the currently installed gems.

• --gem takes a comma separated list of gems to scan for:

deprecool scan --gem=rails,ruby

(make sure there are no spaces between the gem names)

• --format=json if you want the output as json instead of the default text
• --lockfile takes a path to your Gemfile.lock, it defaults to using the current directory
• --all run every finder regardless of applicability
• --paths an array of the files or directories to look for ruby file in, defaults to '.'
