Added git hyper-blame, a tool that skips unwanted commits in git blame.
Currently, the script requires you to pass the unwanted commits on the command line, but eventually, you could configure it with a file (checked into the repo) that provides a fixed set of commits to always skip (such as commits that do a huge amount of renaming and nothing else).

SYNOPSIS
|
||||
--------
|
||||
[verse]
|
||||
'git hyper-blame' [-i <rev> [-i <rev> ...]] [<rev>] [--] <file>
|
||||
|
||||
DESCRIPTION
|
||||
-----------
|
||||
|
||||
`git hyper-blame` is like `git blame` but it can ignore or "look through" a
|
||||
given set of commits, to find the real culprit.
|
||||
|
||||
This is useful if you have a commit that makes sweeping changes that are
|
||||
unlikely to be what you are looking for in a blame, such as mass reformatting or
|
||||
renaming. By adding these commits to the hyper-blame ignore list, `git
|
||||
hyper-blame` will look past these commits to find the previous commit that
|
||||
touched a given line.
|
||||
|
||||
Follows the normal `blame` syntax: annotates `<file>` with the revision that
|
||||
last modified each line. Optional `<rev>` specifies the revision of `<file>` to
|
||||
start from.
|
||||
|
||||
OPTIONS
|
||||
-------
|
||||
|
||||
-i <rev>::
|
||||
A revision to ignore. Can be specified as many times as needed.
|
||||
|
||||
EXAMPLE
|
||||
-------
|
||||
|
||||
Let's run `git blame` on a file:
|
||||
|
||||
demo:1[]
|
||||
|
||||
Notice that almost the entire file has been blamed on a formatting change? You
|
||||
aren't interested in the uppercasing of the file. You want to know who
|
||||
wrote/modified those lines in the first place. Just tell `hyper-blame` to ignore
|
||||
that commit:
|
||||
|
||||
demo:2[]
|
||||
|
||||
`hyper-blame` places a `*` next to any line where it has skipped over an ignored
|
||||
commit, so you know that the line in question has been changed (by an ignored
|
||||
commit) since the given person wrote it.

|
||||
----
|
||||
|
||||
- When a commit is ignored, hyper-blame currently just blames the same line in
|
||||
the previous version of the file. This can be wildly inaccurate if the ignored
|
||||
commit adds or removes lines, resulting in a completely wrong commit being
|
||||
blamed.
|
||||
- There is currently no way to pass the ignore list as a file.
|
||||
- It should be possible for a git repository to configure an automatic list of
|
||||
commits to ignore (like `.gitignore`), so that project owners can maintain a
|
||||
list of "big change" commits that are ignored by hyper-blame by default.
