2007-12-12git-diff --numstat -z: make it machine readableJunio C Hamano
The "-z" format is all about machine parsability, but showing renamed paths as "common/{a => b}/suffix" makes it impossible. The scripts would never have successfully parsed "--numstat -z -M" in the old format. This fixes the output format in a (hopefully minimally) backward incompatible way. * The output without -z is not changed. This has given a good way for humans to view added and deleted lines separately, and showing the path in combined, shorter way would preserve readability. * The output with -z is unchanged for paths that do not involve renames. Existing scripts that do not pass -M/-C are not affected at all. * The output with -z for a renamed path is shown in a format that can easily be distinguished from an unrenamed path. This is based on Jakub Narebski's patch. Bugs and documentation typos are mine. Signed-off-by: Junio C Hamano <gitster@pobox.com>

2007-11-02git-diff.txt: add section "output format" describing the diff formatsGerrit Pape
git-diff.txt includes diff-options.txt which for the -p option refers to a section "generating patches.." which is missing from the git-diff documentation. This patch adapts diff-format.txt to additionally mention the git-diff program, and includes diff-format.txt into git-diff.txt. Tino Keitel noticed this problem.

2007-06-25diff: round down similarity indexRené Scharfe
Rounding down the printed (dis)similarity index allows us to use "100%" as a special value that indicates complete rewrites and fully equal file contents, respectively. Signed-off-by: Rene Scharfe <rene.scharfe@lsrfire.ath.cx> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2007-06-07War on whitespaceJunio C Hamano
This uses "git-apply --whitespace=strip" to fix whitespace errors that have crept in to our source files over time. There are a few files that need to have trailing whitespaces (most notably, test vectors). The results still passes the test, and build result in Documentation/ area is unchanged.

2006-10-26combine-diff: a few more finishing touches.Junio C Hamano
"new file" and "deleted file" were already reported in the original code, but the logic was not as transparent as it could have. This uses a few variables and more comments to clarify the flow. The rule is: (1) if a path exists in the merge result when no parent had it, we report "new" (otherwise it came from the parents, as opposed to have added by the evil merge). (2) if the path does not exist in the merge result, it is "deleted". Since we can say "new" and "deleted", there is no reason not to follow the /dev/null convention. This fixes it. Appending function name after @@@ ... @@@ is trivial, so implement it. Signed-off-by: Junio C Hamano <junkio@cox.net>
2006-10-26diff-format.txt: Combined diff format documentation supplementJakub Narebski
Update example combined diff format to the current version $ git diff-tree -p -c fec9ebf16c948bcb4a8b88d0173ee63584bcde76 and provide complete first chunk in example. Document combined diff format headers: how "diff header" look like, which of "extended diff headers" are used with combined diff and how they look like, differences in two-line from-file/to-file header from non-combined diff format, chunk header format. It should be noted that combined diff format was designed for quick _content_ inspection and renames would work correctly to pick which blobs from each tree to compare but otherwise not reflected in the output (the pathnames are not shown).

2005-09-22Retire diff-helper.Junio C Hamano

2005-09-08Big tool rename.Junio C Hamano
As promised, this is the "big tool rename" patch. The primary differences since 0.99.6 are: (1) git-*-script are no more. The commands installed do not have any such suffix so users do not have to remember if something is implemented as a shell script or not. (2) Many command names with 'cache' in them are renamed with 'index' if that is what they mean. There are backward compatibility symblic links so that you and Porcelains can keep using the old names, but the backward compatibility support is expected to be removed in the near future.

2005-05-30[PATCH] diff-helper: Fix R/C score parsing under -z flag.Junio C Hamano
The score number that follow R/C status were parsed but the parse pointer was not updated, causing the entire line to become unrecognized. This patch fixes this problem. There was a test missing to catch this breakage, which this commit adds as t4009-diff-rename-4.sh. The diff-raw tests used in related t4005-diff-rename-2.sh (the same test without -z) and t4007-rename-3.sh were stricter than necessarily, despite that the comment for the tests said otherwise. This patch also corrects them. The documentation is updated to say that the status can optionally be followed by a number called "score"; it does not have to stay similarity index forever and there is no reason to limit it only to C and R.

2005-05-23[PATCH] diff-raw format update take #2.Junio C Hamano

2005-05-22[PATCH] The diff-raw format updates.Junio C Hamano
Update the diff-raw format as Linus and I discussed, except that it does not use sequence of underscore '_' letters to express nonexistence. All '0' mode is used for that purpose instead. The new diff-raw format can express rename/copy, and the earlier restriction that -M and -C _must_ be used with the patch format output is no longer necessary. The patch makes -M and -C flags independent of -p flag, so you need to say git-whatchanged -M -p to get the diff/patch format. Updated are both documentations and tests.

2005-05-15[PATCH 2/3] Rename git-diff-tree-helper to git-diff-helper.Junio C Hamano
It used to be that diff-tree needed helper support to parse its raw output to generate diffs, but these days git-diff-* family produces the same output and the helper is not tied to diff-tree anymore. Drop "tree" from its name. This commit is done separately to record just the rename and no file content changes. The changes in the renamed files are recorded in the next commit.
