What "diff tool" are you talking about?

The one in the History viewer is automatic if your VCS implementation 
handles the getRevisions() call.  It should return a Vector with 
RevisionInfo instances.  (There is also a VCS.getSource() which takes a 
RevisionInfo as a parameter.)

I want to do a diff on two files (two revisions of a file) to be able to 
generate a new file that I can use in the Merge panel in the History view. 
What I wonder is if there is some way to access the diff engine JBuilder 
uses from within my OpenTool. Is there a method that takes for instance two 
(or three) Urls and returns the diff?

Thanks

This is the API for JBuilderX.  JBuilder2005 has quite a different but much nicer version of this class.

Thank you very much!! Too bad the Diff API for JBuilder2005 is 
undocumented..

Hmm... I just noticed that this class was moved into diff package in JBuilder2005, making it out of the scope of PrimeTime 
OpenTools API.  Not sure why, though.

However, one of the reason that I said it was better was because the API was quite clear.  JBuilder allows you to open up class 
files by showing the methods (without implementation).  If you just open it up and poke around, you should be able to get a 
fairly good idea of it.

I am actually working on a diff opentool for JBuilder, because side-by-side diff is so popular and useful nowadays and I am 
missing that while working with JBuilder.  So make sure you check in to our project page 
(https://jbuilder-opentools.dev.java.net/) Wiki pages for additional updates and stuff.

Thanks,
it seems to work now, but I get an exception while invoking the Diff.diff() 
method:

java.lang.Exception
        at com.borland.primetime.util.diff.Diff.a(Unknown Source)
        at com.borland.primetime.util.diff.Diff.diff(Unknown Source)
        at com.borland.primetime.util.diff.Diff.diff(Unknown Source)

I can still access the DiffMapEntries, any thoughts?

Odd.  An "Exception" rather than anything specific?

How did you invoke it, exactly?

The Exeption is thrown while invoking:

Diff diff = new Diff();
boolean b = diff.diff(new BufferedReader(new FileReader(file),new 
BufferedReader(new StringReader(string))));

When i examine the DiffMap (diff.getDiffMap()) it seems to contain the 
correct diff. Looks like the exeption is thrown in the private method 'a'.

It is a non-specific "Exception" that is generated.

Do I have to initialize or set-up the diff object before invoking the diff() 
method?

Is there anything printed out in the console while this happened?

Other than that I really cannot explain why a non-specific exception was thrown.

It indicates that you have not called Diff.setComparator() before doing the 
diff.

There are two implementation classes provided (and you can write your own 
SequenceComparator implementation):  OnpCompare and OldOnpCompare.

If you do not choose, you get an exception and OldOnpCompare is used.

Ah...  Thanks Bill for explaining the mystery.

Maybe Diff constructor should be changed to require a comparator, then?

Thank you very much! What is the difference between OnpCompare and 
OldOnpCompare?

As the name indicates, the earlier version uses the algorithm in OldOnpCompare, which has some issues.  When JBuilder diff was 
redesigned, this algorithm was rewritten into OnpCompare.

O(np) Compare is a diff algorithm that you should be able to find on the internet.
