Hello,

It seems I'm unable to get DiffMerge 4.20 to ignore space/tab conversions.

The "Line Handling" settings are all enabled, as suggested elsewhere on this forum.

Please see the attachments.

Are my settings correct? If they are, is this a bug and is there a workaround?

What do you have set under Equivalence Mode and Content Handling?

Under Content Handling you want to make sure that you have unchecked that whitespace is importing, but checked that tabs are whitespace.

@Beth -- thank you for your response.

That's exactly what I have.

This is under my "Java Source" ruleset, but just in case, I've also tried setting the default ruleset to same options, and turning off "Enable custom rulesets".

Also:

This is on Fedora Linux 64-bit, DiffMerge 4.20 64-bit, installed via an .RPM.

Tried Windows 8.1 64-bit, same DiffMerge version, same settings, same files --> same result.

Can I send in the actual source files? Would the developer be able to take a look?

On the "View" menu, turn on "Hide Unimportant Differences"
and see if that helps or changes things.

There are too many options I know and it can be a bit
confusing at times. But here are 2 steps in there:

[1] whether to ignore (strip out) spaces and/or tabs
(and case folding and etc) when vertically matching
up lines.

[2] whether to highlight such changes once matched.

There are times when you want 1+2 and sometimes when
you just want 1 turned on.

Let us know if that doesn't take care of it.
Thanks,
jeff

"Hide Unimportant Differences" did the trick.

Thank you Jeff!
