Analyze code for potentially uncalled / dead methods, now with auto-removal.

Features/Problems:

• Static analysis of code. Can be easily hooked up to a CI.

• As with all static analysis tools of dynamic languages, can’t be 100%.

• Whitelisting known good methods by name or regexp.

• Use –rails for Rails-specific domain knowledge.

• Use debride_rm to brazenly remove all unused methods. BE CAREFUL.

• Use debride_rails_whitelist to generate an emperical whitelist from logs.

• Uses path_expander, so you can use:

  • dir_arg – expand a directory automatically

  • @file_of_args – persist arguments in a file

  • -path_to_subtract – ignore intersecting subsets of files/directories
