A very interesting observation, indeed. I use it all the time, but for its intended purpose - to search past existing commits for those in which a particular string appeaed or disappeared. Here, I have interpreted the OP's question as specifically asking about what `git diff` outputs, and it generates the set of differences between the index and the work tree - there is no commit at that stage. Another thing to consider is that the pickaxe looks for a _particular_ string: that is, the user knows what they're looking for up front, and IIUC the OP's question was specifically about _detecting_ the set of strings which were added in the work tree - compared to the state in the index. Hence pickaxe looks quite similar in spirit but I'm not sure its machinery can be employed to do what the OP needs. -- You received this message because you are subscribed to the Google Groups "Git for human beings" group.
