Analyze code for potentially uncalled / dead methods, now with auto-removal.
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
% debride lib These methods MIGHT not be called: MyClass good_method lib/some/file.rb:16 bad_method lib/some/file.rb:20 ...
But you know that good_method is called (perhaps because it is public API), then you can whitelist it:
% echo good_method > whitelist.txt % debride --whitelist whitelist.txt lib These methods MIGHT not be called: MyClass bad_method lib/some/file.rb:20 ...
Usage example for a typical rails application:
# dump rake routes into a file % rake routes > routes.txt # generate whitelist based on routes and usages from production log % debride_rails_whitelist routes.txt log/production.log | sort -u > whitelist.txt # add migration methods % echo up >> whitelist.txt % echo down >> whitelist.txt % echo change >> whitelist.txt # output debride report co standard output with the following options: # ignore typical rails methods, # specify generated whitelist, # run in current directory (".") % debride --rails --whitelist whitelist.txt .
You can also use regexps in your whitelist by delimiting them with //'s.
Extends debride to analyze erb files (via erubis ala rails).

A plugin for the Curly templating language
