When ignoring commits, the commit that is blamed might not be responsible for the change, due to the inaccuracy of our heuristic. Users might want to know when a particular line has a potentially inaccurate blame. Furthermore, guess_line_blames() may fail to find any parent commit for a given line touched by an ignored commit. Those 'unblamable' lines remain blamed on an ignored commit. Users might want to know if a line is unblamable so that they do not spend time investigating a commit they know is uninteresting. This patch adds two config options to mark these two types of lines in the output of blame. The first option can identify ignored lines by specifying blame.markIgnoredLines. When this option is set, each blame line that was blamed on a commit other than the ignored commit is marked with a '?'. For example: 278b6158d6fdb (Barret Rhoden 2016-04-11 13:57:54 -0400 26) appears as: ?278b6158d6fd (Barret Rhoden 2016-04-11 13:57:54 -0400 26) where the '?' is placed before the commit, and the hash has one fewer characters. Sometimes we are unable to even guess at what ancestor commit touched a line. These lines are 'unblamable.' The second option, blame.markUnblamableLines, will mark the line with '*'. For example, say we ignore e5e8d36d04cbe, yet we are unable to blame this line on another commit: e5e8d36d04cbe (Barret Rhoden 2016-04-11 13:57:54 -0400 26) appears as: *e5e8d36d04cb (Barret Rhoden 2016-04-11 13:57:54 -0400 26) When these config options are used together, every line touched by an ignored commit will be marked with either a '?' or a '*'.

-b::
|
|
Show blank SHA-1 for boundary commits. This can also
|
|
be controlled via the `blame.blankboundary` config option.
|
|
|
|
--root::
|
|
Do not treat root commits as boundaries. This can also be
|
|
controlled via the `blame.showRoot` config option.
|
|
|
|
--show-stats::
|
|
Include additional statistics at the end of blame output.
|
|
|
|
-L <start>,<end>::
|
|
-L :<funcname>::
|
|
Annotate only the given line range. May be specified multiple times.
|
|
Overlapping ranges are allowed.
|
|
+
|
|
<start> and <end> are optional. ``-L <start>'' or ``-L <start>,'' spans from
|
|
<start> to end of file. ``-L ,<end>'' spans from start of file to <end>.

-l::
|
|
Show long rev (Default: off).
|
|
|
|
-t::
|
|
Show raw timestamp (Default: off).
|
|
|
|
-S <revs-file>::
|
|
Use revisions from revs-file instead of calling linkgit:git-rev-list[1].
|
|
|
|
--reverse <rev>..<rev>::
|
|
Walk history forward instead of backward. Instead of showing
|
|
the revision in which a line appeared, this shows the last
|
|
revision in which a line has existed. This requires a range of
|
|
revision like START..END where the path to blame exists in
|
|
START. `git blame --reverse START` is taken as `git blame
|
|
--reverse START..HEAD` for convenience.
|
|
|
|
-p::
|
|
--porcelain::
|
|
Show in a format designed for machine consumption.
|
|
|
|
--line-porcelain::
|
|
Show the porcelain format, but output commit information for
|
|
each line, not just the first time a commit is referenced.
|
|
Implies --porcelain.
|
|
|
|
--incremental::
|
|
Show the result incrementally in a format designed for
|
|
machine consumption.
|
|
|
|
--encoding=<encoding>::
|
|
Specifies the encoding used to output author names
|
|
and commit summaries. Setting it to `none` makes blame
|
|
output unconverted data. For more information see the
|
|
discussion about encoding in the linkgit:git-log[1]
|
|
manual page.
|
|
|
|
--contents <file>::
|
|
When <rev> is not specified, the command annotates the
|
|
changes starting backwards from the working tree copy.
|
|
This flag makes the command pretend as if the working
|
|
tree copy has the contents of the named file (specify
|
|
`-` to make the command read from the standard input).
|
|
|
|
--date <format>::
|
|
Specifies the format used to output dates. If --date is not
|
|
provided, the value of the blame.date config variable is
|
|
used. If the blame.date config variable is also not set, the
|
|
iso format is used. For supported values, see the discussion
|
|
of the --date option at linkgit:git-log[1].
|
|
|
|
--[no-]progress::
|
|
Progress status is reported on the standard error stream
|
|
by default when it is attached to a terminal. This flag
|
|
enables progress reporting even if not attached to a
|
|
terminal. Can't use `--progress` together with `--porcelain`
|
|
or `--incremental`.
|
|
|
|
-M[<num>]::
|
|
Detect moved or copied lines within a file. When a commit
|
|
moves or copies a block of lines (e.g. the original file
|
|
has A and then B, and the commit changes it to B and then
|
|
A), the traditional 'blame' algorithm notices only half of
|
|
the movement and typically blames the lines that were moved
|
|
up (i.e. B) to the parent and assigns blame to the lines that
|
|
were moved down (i.e. A) to the child commit. With this
|
|
option, both groups of lines are blamed on the parent by
|
|
running extra passes of inspection.
|
|
+
|
|
<num> is optional but it is the lower bound on the number of
|
|
alphanumeric characters that Git must detect as moving/copying
|
|
within a file for it to associate those lines with the parent
|
|
commit. The default value is 20.
|
|
|
|
-C[<num>]::
|
|
In addition to `-M`, detect lines moved or copied from other
|
|
files that were modified in the same commit. This is
|
|
useful when you reorganize your program and move code
|
|
around across files. When this option is given twice,
|
|
the command additionally looks for copies from other
|
|
files in the commit that creates the file. When this
|
|
option is given three times, the command additionally
|
|
looks for copies from other files in any commit.
|
|
+
|
|
<num> is optional but it is the lower bound on the number of
|
|
alphanumeric characters that Git must detect as moving/copying
|
|
between files for it to associate those lines with the parent
|
|
commit. And the default value is 40. If there are more than one
|
|
`-C` options given, the <num> argument of the last `-C` will
|
|
take effect.
|
|
|
|
--ignore-rev <rev>::
|
|
Ignore changes made by the revision when assigning blame, as if the
|
|
change never happened. Lines that were changed or added by an ignored
|
|
commit will be blamed on the previous commit that changed that line or
|
|
nearby lines. This option may be specified multiple times to ignore
|
|
more than one revision. If the `blame.markIgnoredLines` config option
|
|
is set, then lines that were changed by an ignored commit and attributed to
|
|
another commit will be marked with a `?` in the blame output. If the
|
|
`blame.markUnblamableLines` config option is set, then those lines touched
|
|
by an ignored commit that we could not attribute to another revision are
|
|
marked with a '*'.
|
|
|
|
--ignore-revs-file <file>::
|
|
Ignore revisions listed in `file`, which must be in the same format as an
|
|
`fsck.skipList`. This option may be repeated, and these files will be
|
|
processed after any files specified with the `blame.ignoreRevsFile` config
|
|
option. An empty file name, `""`, will clear the list of revs from
|
|
previously processed files.
