Bug in highlighting

Post by LarsH » Mon Nov 29, 2010 1:50 pm

I am Comparing
OLD
With Dt
.Add("One", "")
.Add("Two", "")
.Add("Four", "")
.Add("Eight", "")
End With

New below
With Dt
.Add(Siffror.One.ToString, "")
.Add(Siffror.Two.ToString, "")
.Add(Siffror.Four.ToString, "")
.Add(Siffror.Eight.ToString, "")
End With


The highlightning goes wrong för the strings "One" and "Two".
I am running Diffmerge Version 3.3.0(18513).
I am reporting this because I really like Diffmerge and it is so exceptionally good, I suppose Your aim is to stay that way.
Regards,
Lars

Can you explain further how the highlighting is off or show a small screenshot?

I put what you posted into text files and performed a compare and came up with the following.

That is the "intra-line smoothing" trying to hide short runs
of equal text within large chunks of modified text. Often times
when comparing 2 pages that have very low correlation, common
letters (like vowels and whitespace) will sync up and just introduce
"visual noise" in the display. The smoothing takes short sequences
and just marks them as different so that we can build a longer run
of text in the same color.

Usually that is a good thing. But in your example, it wasn't.

Visit the Options Dialog and the Detail Level page and decrease the
value of "Intra-line Smoothing Threshold" from 3 to something smaller.
Or set it to 0 to turn it off completely.

Hopefully that'll take care of the problem.

Cheers,
jeff

I did as You suggested. I decreased the "Threshold" from 3 to 2 and then restarted Diffmerge.
It took care of the problem !
Thanks.

Lars
