git-notes - Add or inspect object notes
Adds, removes, or reads notes attached to objects, without touching the objects themselves.
By default, notes are saved to and read from refs/notes/commits, but this default can be overridden. See the OPTIONS, CONFIGURATION, and ENVIRONMENT sections below. If this ref does not exist, it will be quietly created when it is first needed to store a note.
A typical use of notes is to supplement a commit message without changing the commit itself. Notes can be shown by git log along with the original commit message. To distinguish these notes from the message stored in the commit object, the notes are indented like the message, after an unindented line saying "Notes (<refname>):" (or "Notes:" for refs/notes/commits).
To change which notes are shown by git log, see the "notes.displayRef" configuration in git-log(1).
See the "notes.rewrite.<command>" configuration for a way to carry notes across commands that rewrite commits.
List the notes object for a given object. If no object is given, show a list of all note objects and the objects they annotate (in the format "<note object> <annotated object>"). This is the default subcommand if no subcommand is given.
Add notes for a given object (defaults to HEAD). Abort if the object already has notes (use -f to overwrite an existing note).
Copy the notes for the first object onto the second object. Abort if the second object already has notes, or if the first object has none (use -f to overwrite existing notes to the second object). This subcommand is equivalent to: git notes add [-f] -C $(git notes list <from-object>) <to-object>
In \--stdin mode, take lines in the format
<from-object> SP <to-object> [ SP <rest> ] LF
on standard input, and copy the notes from each <from-object> to its corresponding <to-object>. (The optional <rest> is ignored so that the command can read the input given to the post-rewrite hook.)
Append to the notes of an existing object (defaults to HEAD). Creates a new notes object if needed.
Edit the notes for a given object (defaults to HEAD).
Show the notes for a given object (defaults to HEAD).
Remove the notes for a given object (defaults to HEAD). This is equivalent to specifying an empty note message to the edit subcommand.
Remove all notes for non-existing/unreachable objects.
When adding notes to an object that already has notes, overwrite the existing notes (instead of aborting).
Use the given note message (instead of prompting). If multiple -m options are given, their values are concatenated as separate paragraphs. Lines starting with # and empty lines other than a single line between paragraphs will be stripped out.
Take the note message from the given file. Use - to read the note message from the standard input. Lines starting with # and empty lines other than a single line between paragraphs will be stripped out.
Take the note message from the given blob object (for example, another note).
Like -C, but with -c the editor is invoked, so that the user can further edit the note message.
Manipulate the notes tree in <ref>. This overrides GIT_NOTES_REF and the "core.notesRef" configuration. The ref is taken to be in refs/notes/ if it is not qualified.
Do not remove anything; just report the object names whose notes would be removed.
Report all object names whose notes are removed.
Commit notes are blobs containing extra information about an object
(usually information to supplement a commit’s message). These blobs
are taken from notes refs. A notes ref is usually a branch which
contains "files" whose paths are the object names for the objects
they describe, with some directory separators included for performance
[Permitted pathnames have the form ab/cd/ef/…/abcdef…: a sequence of directory names of two hexadecimal digits each followed by a filename with the rest of the object ID.]
Every notes change creates a new commit at the specified notes ref. You can therefore inspect the history of the notes by invoking, e.g., git log -p notes/commits. Currently the commit message only records which operation triggered the update, and the commit authorship is determined according to the usual rules (see git-commit(1)). These details may change in the future.
It is also permitted for a notes ref to point directly to a tree object, in which case the history of the notes can be read with git log -p -g <refname>.
You can use notes to add annotations with information that was not available at the time a commit was written.
$ git notes add -m 'Tested-by: Johannes Sixt <email@example.com>' 72a144e2 $ git show -s 72a144e [...] Signed-off-by: Junio C Hamano <firstname.lastname@example.org> Notes: Tested-by: Johannes Sixt <email@example.com>
In principle, a note is a regular Git blob, and any kind of (non-)format is accepted. You can binary-safely create notes from arbitrary files using git hash-object:
$ cc *.c $ blob=$(git hash-object -w a.out) $ git notes --ref=built add -C "$blob" HEAD
Of course, it doesn’t make much sense to display non-text-format notes with git log, so if you use such notes, you’ll probably need to write some special-purpose tools to do something useful with them.
Notes ref to read and manipulate instead of refs/notes/commits. Must be an unabbreviated ref name. This setting can be overridden through the environment and command line.
Which ref (or refs, if a glob or specified more than once), in addition to the default set by core.notesRef or GIT_NOTES_REF, to read notes from when showing commit messages with the git log family of commands. This setting can be overridden on the command line or by the GIT_NOTES_DISPLAY_REF environment variable. See git-log(1).
When rewriting commits with <command> (currently amend or rebase), if this variable is false, git will not copy notes from the original to the rewritten commit. Defaults to true. See also "notes.rewriteRef" below.
This setting can be overridden by the GIT_NOTES_REWRITE_REF environment variable.
When copying notes during a rewrite, what to do if the target commit already has a note. Must be one of overwrite, concatenate, and ignore. Defaults to concatenate.
This setting can be overridden with the GIT_NOTES_REWRITE_MODE environment variable.
When copying notes during a rewrite, specifies the (fully qualified) ref whose notes should be copied. May be a glob, in which case notes in all matching refs will be copied. You may also specify this configuration several times.
Does not have a default value; you must configure this variable to enable note rewriting.
Can be overridden with the GIT_NOTES_REWRITE_REF environment variable.
Which ref to manipulate notes from, instead of refs/notes/commits. This overrides the core.notesRef setting.
Colon-delimited list of refs or globs indicating which refs, in addition to the default from core.notesRef or GIT_NOTES_REF, to read notes from when showing commit messages. This overrides the notes.displayRef setting.
A warning will be issued for refs that do not exist, but a glob that does not match any refs is silently ignored.
When copying notes during a rewrite, what to do if the target commit already has a note. Must be one of overwrite, concatenate, and ignore. This overrides the core.rewriteMode setting.
When rewriting commits, which notes to copy from the original to the rewritten commit. Must be a colon-delimited list of refs or globs.
If not set in the environment, the list of notes to copy depends on the notes.rewrite.<command> and notes.rewriteRef settings.
