How to compare bettwen .rev file

[Brian Yennie]

Joe, Tran,

Building on this - instead of counting characters, you could run the  
scripts through md5Digest(). Using a hash value is a common approach  
to detecting changes that works very well for almost all cases.

It all really depends on the level of changes you need to see - but if  
it's just scripting changes, looping through all objects and comparing  
their md5Digest() values is a good start. If you want more in-depth  
analysis (for example tracking property changes to objects or the  
formatting of text), it could be quite a bit more work.

Since there is no "true" version tracking / merging tool for Rev, it  
also has a lot to do with your collaborative process. A few people  
here have their own homegrown tools for versioning that work quite  
well. For those accustomed to CVS / SVN it's not quite the same ball  
game, but that's arguably a good thing =).
