Use correct grammar in diffstat summary line

2012-02-04T07:19:42Z

"git diff --stat" and "git apply --stat" now learn to print the line "%d files changed, %d insertions(+), %d deletions(-)" in singular form whenever applicable. "0 insertions" and "0 deletions" are also omitted unless they are both zero. This matches how versions of "diffstat" that are not prehistoric produced their output, and also makes this line translatable.

pass struct commit to diff_tree_combined_merge()

2011-12-18T02:22:29Z

Instead of passing the hash of a commit and then searching that same commit in the single caller, simply pass the commit directly. Signed-off-by: René Scharfe Signed-off-by: Junio C Hamano

use struct sha1_array in diff_tree_combined()

2011-12-18T02:21:37Z

Maintaining an array of hashes is easier using sha1_array than open-coding it. This patch also fixes a leak of the SHA1 array in diff_tree_combined_merge(). Signed-off-by: René Scharfe Signed-off-by: Junio C Hamano

diff: add option to show whole functions as context

2011-10-10T19:05:07Z

Add the option -W/--function-context to git diff. It is similar to the same option of git grep and expands the context of change hunks so that the whole surrounding function is shown. This "natural" context can allow changes to be understood better. Note: GNU patch doesn't like diffs generated with the new option; it seems to expect context lines to be the same before and after changes. git apply doesn't complain. This implementation has the same shortcoming as the one in grep, namely that there is no way to explicitly find the end of a function. That means that a few lines of extra context are shown, right up to the next recognized function begins. It's already useful in its current form, though. The function get_func_line() in xdiff/xemit.c is extended to work forward as well as backward to find post-context as well as pre-context. It returns the position of the first found matching line. The func_line parameter is made optional, as we don't need it for -W. The enhanced function is then used in xdl_emit_diff() to extend the context as needed. If the added context overlaps with the next change, it is merged into the current hunk. Signed-off-by: Rene Scharfe Signed-off-by: Junio C Hamano

diff: refactor COLOR_DIFF from a flag into an int

2011-08-18T21:35:53Z

This lets us store more than just a bit flag for whether we want color; we can also store whether we want automatic colors. This can be useful for making the automatic-color decision closer to the point of use. This mostly just involves replacing DIFF_OPT_* calls with manipulations of the flag. The biggest exception is that calls to DIFF_OPT_TST must check for "o->use_color > 0", which lets an "unknown" value (i.e., the default) stay at "no color". In the previous code, a value of "-1" was not propagated at all. Signed-off-by: Jeff King Signed-off-by: Junio C Hamano

diff: futureproof "stop feeding the backend early" logic

2011-05-31T16:21:36Z

Refactor the "do not stop feeding the backend early" logic into a small helper function and use it in both run_diff_files() and diff_tree() that has the stop-early optimization. We may later add other types of diffcore transformation that require to look at the whole result like diff-filter does, and having the logic in a single place is essential for longer term maintainability.

diff: introduce --stat-lines to limit the stat lines

2011-05-27T17:44:34Z

Often one is interested in the full --stat output only for commits which change a few files, but not others, because larger restructuring gives a --stat which fills a few screens. Introduce a new option --stat-count= which limits the --stat output to the first lines, followed by a "..." line. It can also be given as the third parameter in --stat=,,. Also, the unstuck form is supported analogous to the other two stat parameters. Signed-off-by: Michael J Gruber Signed-off-by: Junio C Hamano
