Description thulin 2007-03-30 09:59:21 UTC
The formatting of two version of a file often differs if several IDE:s are used
in a project. It would be nice to have a option for diff to ignor *all* formatting. 
The following code would not be different:
if (true) { foo = 1 + 3;

   foo=1+3 ;

Conceptually you could think of this enhancement as a bytecode diff operation.

This would be a great feature, since this is what you are up-to when compareing java files: What's been changed
logically, and not what formatting has changed.

I hope this will be implemented someday :-)

It is not about ignoring the format. It is easier to format both sides the same way and then compare them.

It would be also feasible to create a plugin for this. Both sides/streamsources (left and right) are being formatted before showing the creating the diff.

Basically the same thing :-) Just it would be great to be able to skip the code noise.

additionally fields and methods could be sorted so their order would not matter as well.
