Shannon Booth	dd373eacbc	LibDiff+patch: Support multiple patches in a single patch file ... Multiple patches may be concatenated in the same patch file, such as git commits which are changing multiple files at the same time. To handle this, parse each patch in order in the patch file, and apply each patch sequentially. To determine whether we are at the end of a patch (and not just parsing another hunk) the parser will look for a leading '@@ ' after every hunk. If that is found, there is another hunk. Otherwise, we must be at the end of this patch.	2023-07-30 07:47:22 +01:00
Shannon Booth	f893e0820f	patch: Support creation of a file ... Previously patch would always expect the file that it was patching to exist (even it were empty). If we know that the patch is creating a file from nothing (i.e has a start line of '0'), then we treat a file that doesn't exist as if it has no content lines.	2023-07-30 07:47:22 +01:00
Shannon Booth	81df0278b1	patch+LibDiff: Implement 'strip' of filenames when parsing patch ... Implement the patch '-p' / '--strip' option, which strips the given number of leading components from filenames parsed in the patch header. If not given this option defaults to the basename of that path.	2023-07-29 17:09:09 -06:00
