The TM_MODE variable is the display name of the currently selected  
grammar, which can technically be anything and does not reflect how  
languages can be embedded into each other (e.g. you can have HTML in  
Ruby, JavaScript in HTML, SQL in PHP, etc.).

The TM_SCOPE variable shows the actual context but a more elegant  
solution is to introduce a variable a la TM_CODE_SEARCH_TERM and set  
this to the proper term for the various scopes.

This is because you output the actual page source from the command, if  
you want to do that, you need to insert a <base> tag so that relative  
links resolve properly.

But the better approach is to do something like:

     print "<meta http-equiv='Refresh' content='0;URL=%s'>" % QUERY

If you refer to the version of the repository, no, but it moved to: http://svn.textmate.org/trunk/

I don’t follow your setup. But if you plan to submit patches you want  
to svn co the bundle you want to contribute to to ~/Library/ 
Application Support/TextMate/Bundles so that TextMate does not create  
delta files.

There is a github mirror of the svn repository: http://github.com/kballard/textmate-bundles/tree

You can easily make such command yourself — if you have the  
interactive input library (included in latest cutting edge) you can  
simply make the command read from stdin for what to execute (rather  
than use DIALOG directly or via lib/ui.rb).
