I am an IBM i developer, using Rational Developer for Power [RDP] with EGit.

Traditional source files on our platform include a built-in line sequence number in columns 1-6, and a line change date in columns 7-12. This causes headaches when doing file comparisons, because the sequence or date may have changed, while everything else on the line may be the same.

Is there any way to customize the comparison to avoid this problem?


The latest RDP version 8.5 is based on Eclipse 3.6.3, so I have loaded EGit 2.1, and the merge tool is configured with KDiff3.

Not that I know of.

For C Git: BeycondCompare can do this easily, but it's only available for Windows and Linux on intel/amd (might be possible to use with wine) and carries a small fee, but
it's worth every cent.

It is also possible to define a textconv filter that massages the data before presenting it to the diff tool. See gitattributes(5). EGit does not yet support gitattributes,
but there is some work going into that direction. https://git.eclipse.org/r/#/c/1614 if you want to help.
