iain / metrical Goto Github PK

Apparently Metrical depends on the ripper gem but it's not in the dependencies. I had to install it manually.

can't activate ruby_parser (~> 2.0.4, runtime) for ["churn-0.0.13", "metric_fu-2.1.1", "metrical-0.0.7"], already activated ruby_parser-2.3.1 for "flay-1.4.2", "metric_fu-2.1.1", "metrical-0.0.7"

The current version of rcov, 1.0.0, will not install on Ruby 1.9. I had to explicitly install the previous version, 0.9.11, then I could install metrical without error.

Seeing this, what is the status of metrical. Does it need a lot of work to get working?

When using rubygems-bundler, all the gem binstubs get a "bundle exec" wrapper, which causes Metrical to not work.

The solution is to add this line to your .bash_profile and gem regenerate_binstubs.

export BUNDLER_BLACKLIST="metrical churn flay reek roodi rcov saikuro rails_best_practices"

I get following error when i try to run metrical. I don't know if its flog problem in ruby 1.9.2.

With ruby 1.9.3, when trying to install metrical:

$ gem install metrical
ERROR: While executing gem ... (Gem::DependencyError)
Unable to resolve dependencies: metrical requires main (> 4.6.0); metric_fu requires chronic (> 0.3.0); churn requires chronic (= 0.6.4), main (= 4.7.7), main (>= 0), chronic (>= 0.2.3)

Hi, I just tried out metrical and think its great. Thinking of changing it to run with 1.9 source code - in fact I already did a nasty hack running all .rb files through a gsub that replaces 1.9 with 1.8 hash syntax and tada all metrics are generated.
(see https://github.com/bkleinen/hash-reverter - three files to put in an rails app - still rather rough, if it's going to stick has to be converted to a gem).

Thus my approach would be to include that to metrical, split up the metric tools into those that do support 1.9 and those which don't , and run everything in two passes, and migrate them to 1.9 one by one.

As finally the ruby_parser seems to get updated to support 1.9 hashes in version 3, I hope that it will become easier upgrading the tools, too.

I've forked metrical, https://github.com/bkleinen/metrical , but not yet sure if I will be able to maintain it, but I'm looking into that.

Any comments on my approach welcomed.

I added metrical in my gemfile
gem 'metrical', :require => false
bundle install
bundle exec metrical gave the following error

.rvm/gems/ruby-1.9.3-p374/gems/ruby_parser-2.3.1/lib/ruby_parser_extras.rb:612:in `initialize': invalid multibyte escape: /[\x80-\xff]/ (RegexpError)

rails version : 3.2.9
ruby version : 1.9.3

What should i change to run metrical successfully.?

Hi,

I run on:

ruby 1.8.7
rails 3.0.3
metrical 0.0.4
metric_fu 2.0.1
ruby_parser 2.0.6

In my code I have a comment block, like

=begin
  This will crash
=end

The block causes the command 'metrical' to produce an error:

changing the above comment block to

#=end

"fixes" the parser error.

Thanks for metrical. Here's an error message I'm getting because metrical requires metric_fu, requires churn, requires an incompatible version of ruby_parser.

I've opened this issue with the churn author. Thanks, Joel ([email protected])

Bundler could not find compatible versions for gem "ruby_parser":
In Gemfile:
metrical depends on
ruby_parser (~> 2.0.4)

ruby_parser (2.3.0)

Hi,

I am getting the following error when I try to run the metrical gem

braga@braga-laptop:~/prj/dummy_app$ metrical

The Rails Version I am using is 2.3.14 and the Ruby version is 1.8.7

I read through a bunch of posts regarding metric_fu and metrical and many places I am seeing this dependency problem. Some of the blog posts say that they were resolved. But then they have become old enough and the dependent gems have updated themselves making the above error to appear again.

Can somone tell me how to resolve this error?

Thanks

Churn is a culprit here. That won't install stand alone.

Re:

"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."

The problem is with the roodi.yml file (https://github.com/martinjandrews/roodi/blob/master/roodi.yml), see this ignored pull request: roodi/roodi#9. I've applied the change to my roodi.yml file and roodi now runs fine.

It looks like the roodi gem has is not being maintained. One solution is to edit the yml file manually (what i did), the other is to publish a fixed version of the gem so the metric_fu gemspec can reference the fixed published gem.

It could be helpful to add the link to the fixed rood.yml file and pull request on the readme.

I hope this saves someone else some time.
