First (Scruffy) SVN GUI for Mac OS

[Wilfredo Sanchez <ws...@mit.edu>]

  Mac OS X users, dig this.

   I have a GUI that works in Mac OS.  There is a beautiful irony here, 
and it's written 100% in the Bourne shell, with no GUI code at all.  
Instead, it relies on support from existing applications.

   I have this app I wrote called DropScript, which turn shell scripts 
into Cocoa applications that run the shell scripts.  The spiffy thing 
is that you can drag files onto the app icon and the script processes 
the files.  In order to make this SVN thing work, I added a feature 
which allows these apps to export "applications services" to other 
applications, and I wrote a tool (in sh also) which uses AppleScript to 
script the Terminal app and has a calling interface somewhat like xterm.

   Anyway, you can now use Finder to do many SVN operations.  For 
example, make a new folder somewhere and pull down the 
"Services->Subversion->Check Out Repository" menu, which will happily 
bring up a Terminal window which asks for the repository name and a 
subdirectory to drop it into.

   Or select some files in the WC and try "Services->Subversion->View 
Changes (FileMerge)" to see the changes in your files using the rather 
spiffy FileMerge application.  Or get view in a diff file if you 
prefer.  Get status, logs, etc.

   It's rather basic in that it doesn't generally allow you to specify 
options (eg. you can update, but can't specify the revision to update 
to), but it's fairly useful and if we ever get something like Tk for 
Aqua, we can add richer UI.  But for now, it's a start.

   You can grab a dev version of DropScript here:

	http://www.mit.edu/people/wsanchez/tmp/svn/

   It's a disk image which includes DropScript, example scripts 
(including the SVN scripts) and premade applications from the example 
scripts.  Put the apps into ~/Applications and log out and back in.  
You should see a Subversion menu (and maybe others) in Finder's 
Services menu.

   It will also appear in the Services menu for any application that 
declares it can send file references.  There's aren't many that I can 
find, but PathFinder (was SNAX), which is a Cocoa Finder-like app is an 
example which works.

   A couple of screenshots are above as well, in case you wanna see it 
first or don't have Mac OS X.

   I'm testing on 10.2, so it might crap out on 10.1, though I don't see 
why it would, offhand.  Source is in Darwin CVS.
