Created attachment 232891 [details] patch to add feature 'compare with each other (filtered)' It would be great to have the opportunity to define a set of rules in order to ignore certain differences between files in a tree compare. E.g. the line with the CVS/SVN keyword 'Id' changes after every commit, which is a difference that one might want to ignore. (see also [01] [02] [03]) Using Regexes to define ignored changes, such a line of change could be ignored with a Regexp like '.*\$Id:.*'. Also other rules could be useful such as ignoring changed imports ('^import.*'). We implemented our own plugin which supports an option to define a list of ignored changes for a tree compare. If a regexp matches a change, this change will be ignored and the corresponding file will not show in the compare tree unless there are other not-ignored changes in the same file [04]. However, as we feel that this feature could also be useful for others, we'd like to share it with the eclipse community if there is interest. A simple way to add this to eclipse would be to add a menu entry to the context menu: 'Compare With > Each Other (filtered)'. Also the option to configure the ignore regular expressions could be added to preferences page 'General > Comapare/Path'. We are pleased to provide you a sample implementation of this feature [05]. A few words to the attached patch: We could not checkout the compare module from the CVS repo [06]. So we started this patch with the Kepler SDK: org.eclipse.compare (3.5.400.v20130514-1224). I hope you can work with it. If you prefer a different form of the patch let me know it...
