Rubocop is a style checker for Ruby. See the project's page for details.

Notes

• Most issues returned by rubocop are warnings, so for best results your g:syntastic_quiet_messages should not filter out warnings.
• Only rubocop versions 0.12.0 and later are supported.
• Running rubocop under development versions of ruby is not supported, sorry.
• Mixing different versions of ruby is not supported either. If the rubocop checker is not enabled automatically by syntastic, try running rubocop --version from the shell. If it complains about parser expecting a different version of ruby than you are running, your configuration is not directly supported by syntastic. While passing around the blame for this does have a certain entertaining value, the problem is real, since ruby syntax did change between versions. The solution is to run a system such as rbenv or rvm, that allows you to run multiple versions of ruby without conflicts.

$ rbenv version
2.1.3 (set by /usr/local/var/rbenv/version)

$ rubocop --version
warning: parser/current is loading parser/ruby21, which recognizes
warning: 2.1.2-compliant syntax, but you are running 2.1.3.
0.26.1

$ rbenv shell 2.1.2

$ rubocop --version
0.26.1

• Alternatively, if you absolutely must do it the wrong way, you can also install this wrapper script and point g:syntastic_ruby_rubocop_exec to it. However, doing that voids your guarantee. Don't bother reporting any problems if you do it.
