I have three patch series that makes a part of git-grep available and use it for log filtering: [PATCH] builtin-grep: make pieces of it available as library. [PATCH] revision traversal: prepare for commit log match. [PATCH] revision traversal: --author, --committer, and --grep. I didn't implement the boolean combination of patterns like git-grep does, but it should be pretty straightforward to do so in setup_revisions(). The syntax probably would be something like: git log --grep-( rev-list gitweb --and --not --author=Jakub --grep-) to find logs that: * talk about rev-list, or * talk about gitweb but not by Jakub - To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
