Shawn O. Pearce a25c518933 git-gui: Allow staging/unstaging individual diff hunks. Just like `git-add --interactive` we can now stage and unstage individual hunks within a file, rather than the entire file at once. This works on the basic idea of scanning backwards from the mouse position to find the hunk header, then going forwards to find the end of the hunk. Everything in that is sent to `git apply --cached`, prefixed by the diff header lines. We ignore whitespace errors while applying a hunk, as we expect the user's pre-commit hook to catch any possible problems. This matches our existing behavior with regards to adding an entire file with no whitespace error checking. Applying hunks means that we now have to capture and save the diff header lines, rather than chucking them. Not really a big deal, we just needed a new global to hang onto that current header information. We probably could have recreated it on demand during apply_hunk but that would mean we need to implement all of the funny rules about how to encode weird path names (e.g. ones containing LF) into a diff header so that the `git apply` process would understand what we are asking it to do. Much simpler to just store this small amount of data in a global and replay it when needed. I'm making absolutely no attempt to correct the line numbers on the remaining hunk headers after one hunk has been applied. This may cause some hunks to fail, as the position information would not be correct. Users can always refresh the current diff before applying a failing hunk to work around the issue. Perhaps if we ever implement hunk splitting we could also fix the remaining hunk headers. Applying hunks directly means that we need to process the diff data in binary, rather than using the system encoding and an automatic linefeed translation. This ensures that CRLF formatted files will be able to be fed directly to `git apply` without failures. Unfortunately it also means we will see CRs show up in the GUI as ugly little boxes at the end of each line in a CRLF file. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>		18 years ago
