Accessing Subversion Repository Information In Ruby

08.07.2006

| 4018 views |

require 'yaml'
svn_info = YAML.load(`svn info /my/working/copy`)
puts svn_info['URL']
#=> "svn://some-remote-repository.com/svn"
puts svn_info['Revision']
#=> "133"


Should also work with svk info as well. Credit to htonl in #caboose for the YAML tip.

Of course, this won't work if you're deploying through Capistrano and using svn export. Which we all _should_be doing, right?

or you can use:


YAML.parse(`svnversion #{RAILS_ROOT}`).value

Hm, I tried doing svn info recursively. It is bit slow (few seconds) but it works!


require 'yaml'

def get_svn_revision
  return nil if $RAILS_ENV == 'production'
  
  max = 0
  entries = `svn info -R #{RAILS_ROOT}/*`.split(/\n\n/)
  entries.each do |entry|
    r = YAML.parse(entry)['Revision'].value.to_i
    max = r if r > max
  end
  return max
end

$SVN_REVISION = get_svn_revision

Unfortunately, this only returns the revision number of #{RAILS_ROOT} (natch), which (at least in my case) is always going to to be "1", regardless of how many revisions the contained files undergo. Is there a way to pull the revision of the most recently updated child item?
