= Excellent
Excellent detects commonly regarded bad code snippets like empty +rescue+ blocks etc. It combines roodi (http://github.com/martinjandrews/roodi), most checks of reek (http://github.com/kevinrutherford/reek), flog (http://github.com/seattlerb/flog) and also adds some Rails specific checks.
See the API documentation at http://docs.github.com/simplabs/excellent and the WIKI at http://wiki.github.com/simplabs/excellent.
== Installation
Simply install with Ruby Gems:
gem sources -a http://gems.github.com
sudo gem install simplabs-excellent
== Example
To analyse all the models in your Rails application, just do
excellent app/models
in your RAILS_ROOT. You can also invoke analysation through the Simplabs::Excellent::Runner class. Excellent can also produce HTML output. To
get a formatted HTML report, just specify html::
excellent html:out.html app/models
You can also use Excellent in a Rake task:
require 'simplabs/excellent/rake'
Simplabs::Excellent::Rake::ExcellentTask.new(:excellent) do |t|
t.html = 'doc/excellent.html' # optional, if you don't specify html, output will be written to $stdout
t.paths = %w(app lib)
end
== Static analysis
A few words regarding static code analysis: Static code analysis tools like Excellent can never really understand the code. They just search for patterns that *might* inidicate problematic code. The word *might* really has to be stressed here since static analysis will usually return a reasonable number of false positives. For example, there might be pretty good reasons for empty +rescue+ blocks that suppress all errors (Excellent itself does it). So, don't try and code with the aim of passing Excellent with zero warnings. That will most likely make your code a mess. Instead use Excellent as a helper to find *possibly* problematic code early.
== Contribute
If you want to contribute, just fork the repo. Also I would appretiate suggestions for more checks (especially Rails specific checks) - simply open a new issue: http://github.com/simplabs/excellent/issues.
