Cannot run metric_fu because gem dependency regex fails #298

I get an error if I try to run metric_fu on my rails project:

The problem is that the ADD_DEPENDENCY_CALL regex fails. If I debug, the failing line is the following:

s.add_runtime_dependency(%q<flay>.freeze, [">= 2.0.1", "~> 2.1"])

It seems that there is a .freeze included which is not supported in the regex.

bf4 commented 7 years ago

Where is that %q<flay>.freeze coming from?

phylor commented 7 years ago

@bf4 Good point. I created a new rails project and that problem didn't occur. I'll check when that happens.

phylor commented 7 years ago

@bf4 This seems to be an issue with Ruby 2.2 (.freeze is present). It works with 2.3 (.freeze not present). So I guess the question is if you want to support Ruby 2.2? As far as I understand, metric_fu is only doing static analysis, so you could run it with a different Ruby version than the project under test, right?

Some more information to reproduce the issue: I created a new rails project using rails new metric-fu-test and added the master branch to the Gemfile.

See the output below (I'm using rbenv to switch Ruby versions).

Output for Ruby version 2.2:

@bf4 Any news? Do you want to support Ruby 2.2?

bergholdt commented 7 years ago

Hi @phylor

I tried reproduce the error using your guide above, but my Ruby 2.2 does not result in every string having .freeze present.

➜  metric-fu-test git:(ruby2.2) ✗ ruby -v

# -*- encoding: utf-8 -*-
$:.push File.expand_path("../lib", __FILE__)
require "metric_fu/version"

  end

Could you have some global settings on your Ruby 2.2 that force frozen_string_literal, not that I have been able to find an option like that.

What happen if you make a fresh install of ex 2.2.6 - does that also result in .freeze?

bergholdt commented 7 years ago

Hi @phylor

I have setup a travis build on an empty rails 5 app and this actually resulted in the same error you reported.

https://travis-ci.org/bergholdt/metric-fu-test/builds/207499291

"Funny" thing is that .frozen was present on 2.3.3 and not 2.2.6 ... Wish I could reproduce this locally though.

bergholdt commented 7 years ago

Hi again 😊

Notices that the gem --version was not identical on the two travis builds.

So made a new build using latest ruby gem (version 2.6.10) and this introduced .freeze

https://travis-ci.org/bergholdt/metric-fu-test/builds/207502824

bergholdt commented 7 years ago

@bf4 think we need @phylor regex fix to support rubygems >= 2.6

https://github.com/rubygems/rubygems/blob/73ffc455b80394a491a51d6157a36f839de3e228/History.txt#L186

Build using this PR https://travis-ci.org/bergholdt/metric-fu-test/builds/207510157 Successful 🥇

phylor commented 7 years ago

@bergholdt Sorry for the slow response, but thank you very much for the investigation and resolution!
