Rails - Jul 2006 - embedding subversion version information into HTML

Hi,

Say I want to display the subversion release number in the footer of
each page in order to track what version of a site I''m looking at.

I know subversion has a substitution keyword (LastChangedRevision)
that inserts the last known revision in which that file .changed.

So, if I stick $LastChangedRevision$ into
views/layouts/application.rhtml, it''ll show the last time that file
was changed, not the current version of the repository.  W hich isn''t
quite what I want.  Any ideas?

Thanks,
Joe

I haven''t found a solution other than to modify the keyworded file  
every time I commit to svn.

Love to hear another solution, but since svn only commits modified  
files, substitution can only happen when this file is changed.

Can you use File.open to get at the info from your .svn directory?   
If not, you could use open-uri to download the info from a repository.

Don,

I use `svn info` inside of the checked out directory and then parse results.

Here''s a method we use internally:

  def svn_version
    File.new(".svn/entries").each do |x|
      if md = /^[\s]*url=".*tags\/REL-([\d\.-]+)/.match(x)
        return md[1]
      elsif md = /^[\s]*url=".*branches\/([^\/"]+)/.match(x)
        return md[1]
      elsif md = /^[\s]*revision="([\d]+)/.match(x)
        return md[1]
      end
    end
    return ''(unknown version)''
  end

.. it does some nice things if you''ve deployed from a tag or a branch,
as well as just returning the raw revision number.

Hi Joe,
you can create dynamically partial template when deploying with 
capistrano, for example add this code to deploy.rb

task :after_update_code, :roles => [:web] do
   put(revision, "#{release_path}/app/views/layouts/_version.rhtml")
end

and include it in layout with

Revision: <%= render_partial(''/layouts/version'')%>


hope that helps you,
Bojan Mihelac

You are simply not sing the right keyword, if you want the latest 
revision place $Rev$ or $Revision$ somewhere in your code, the result 
will be: "$Rev: 552 $"
One thing to keep in mind is that you need to make a change to the file 
where you put the "$Rev$" keyword to make it change.

You could use svnversion to crawl your working copy redirect its output into a 
separate file that is included in all your views or use it in a sed like command
to change each of your views.

$Rev$ is shorthand for $LastChangedRevision$.

The problem is that I don''t want to have to update the file in order
to get the repository version.

I think Bojan (thanks!) has the solution.
