Hi!

I'm having some trouble since commit 9ee737177a6be5b9759de858d49436be2d5e5625. I'm using Capifony with Vagrant and receive the following error when i try to deploy.

/opt/vagrant_ruby/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:36:in `gem_original_require': /opt/vagrant_ruby/lib/ruby/gems/1.8/gems/inifile-3.0.0/lib/inifile.rb:558: undefined (?...) sequence: /\A"(.*)(?<!\\)"\z/ (SyntaxError)
from /opt/vagrant_ruby/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:36:in `require'
from /opt/vagrant_ruby/lib/ruby/gems/1.8/gems/capifony-2.8.0/lib/capifony_symfony2.rb:6

Looks like the following line is giving trouble:

self.value = $1 if value =~ %r/\A"(.*)(?<!\\)"\z/m

Is it a bug in inifile?

The inifile gem is not compatible with ruby 1.8. That particular regular expression is using negative look-behind which is only supported in ruby 1.9 and higher.

Thank you, in that case i'm going to update Ruby

Nevertheless, some backwards compatibility would we awesome.

TwP commented 10 years ago

This was a major version bump to 3.0 indicating that it has backwards incompatible changes. You can use the previous version for ruby 1.8 applications. But the lack of negative look-behind in the ruby 1.8 regular expression engine prohibits these changes from being back ported to a ruby 1.8 compatible version.
