Need a tool to compare two C-source files

[Jaap Weidemann]

If you're willing to throw some money at it, I'd recommend Beyond Compare or UltraCompare.

The two files are an old and a new version of my chessprogram Dabbaba.
Each file consists of about 10.000 text-lines.

I want to see which lines are added, deleted og changed - and don't want to bother about all the many lines that are unchanged.

I use KDiff3: http://kdiff3.sourceforge.net/
It is easy and very good.

Thanks for all your replies.

I tried WinMerge and it is awesome for my needs

Eclipse has a 2-way (and 3-way) graphical diff and merge capability for text files. It can also perform recursive directory compares.

Comparisons can be performed between any files or directories in the workspace, or any historical versions stored either by Eclipse ("local history") or your choice of version control system (CVS, Subversion, Git, etc).

There is one other that is even better than WinMerge (which is very good).

ExamDiff Pro

http://www.prestosoft.com/edp_examdiff.asp

You can examine binaries with the pro version which has a free trial.

I have used this before for php coding (and also "other" chess related purposes)

In the pay-for category, I rather like Araxis Merge.

I use tkdiff to compare source files.

kdiff3, it's a wonderful program. Has two columns for each document and highlights which lines are different and adds space when there are lines in one file but another.

Use it all the time, and not only for C it's applicable for any text file (even binary if you don't mind reading hex).

If there are many trivial changes it might be worthwhile to compare the output of indent on each file instead of the files themselves. Indent will format C source to a particular style.
