MetricFu is awesome! Metrical strives to make it a little bit easier to get working.
Metrical makes it easy to run MetricFu without making it a project dependency. Bundler requires that everything you need go inside the Gemfile. MetricFu is rather big project with a ton of dependencies. Including that inside your Gemfile just clutters it up.
Also, MetricFu wants to be installed inside your Rakefile. With Metrical, you can configure MetricFu
in a separate file, .metrics in the root of your project.
Normally, RCov would work on a black-listing basis. This means that your coverage reports would
occasionally be flooded with code outside your project. No longer, because the default is now to
exclude everything and only include your lib and app directories. It also fixes some issues with
loading RSpec.
Install:
gem install metrical
Run:
metrical
You can configure MetricFu in a .metrics file in the root of your project.
MetricFu::Configuration.run do |config|
config.metrics -= [ :rcov ]
end
For more information on configuring your metrics, please visit the MetricFu homepage.
And that's all there is too it. If you have any suggestions, ideas or bug fixes, please drop me a line, or make a github issue.
RCov doesn't work with Ruby 1.9. You should use something like SimpleCov. Unfortunately, it hasn't been included into MetricFu yet. Until then, make sure to remove RCov from MetricFu, as the example above shows.
Most metrics can't cope with the new syntax in Ruby 1.9. There is nothing I can do about that, or
the creator of these metrics, because the root lie in the code parser they use. Either don't use the
new syntax or exclude these metrics in your .metrics file.
If you're running Ruby 1.9 with Psych as your default YAML parser (possible in 1.9.2, and the default in 1.9.3), you might get an error message. I have no clue what to do about it. Some help on this would be greatly appreciated.
Metrical depends on a lot of other gems. Not all gem authors adhere to guidelines such as SemVer. This means that sometimes, when a new version of a gem is released, things break. I try to fix the issues I come across inside Metrical, by making a dependency of a dependency a fixed dependency of Metrical. It's difficult to do this right.
If you get a message like can't activate X, already activated Y, or something similar, you can
open an issue. Please include the entire error message and the output of gem list and the version
of Ruby you are using.
