  21DESCRIPTION
  22-----------
  23Adds, removes, or reads notes attached to objects, without touching
  24the objects themselves.
  25
  26By default, notes are saved to and read from `refs/notes/commits`, but
  27this default can be overridden.  See the OPTIONS, CONFIGURATION, and
  28ENVIRONMENT sections below.  If this ref does not exist, it will be
  29quietly created when it is first needed to store a note.
  30
  31A typical use of notes is to supplement a commit message without
  32changing the commit itself. Notes can be shown by 'git log' along with
  33the original commit message. To distinguish these notes from the
  34message stored in the commit object, the notes are indented like the
  35message, after an unindented line saying "Notes (<refname>):" (or
  36"Notes:" for `refs/notes/commits`).
  37
  38To change which notes are shown by 'git log', see the
  39"notes.displayRef" configuration in linkgit:git-log[1].
  40
  41See the "notes.rewrite.<command>" configuration for a way to carry
  42notes across commands that rewrite commits.
  43
  44
  45SUBCOMMANDS
  46-----------
  47
  48list::
  49        List the notes object for a given object. If no object is
  50        given, show a list of all note objects and the objects they
  51        annotate (in the format "<note object> <annotated object>").
  52        This is the default subcommand if no subcommand is given.
  53
  54add::
  55        Add notes for a given object (defaults to HEAD). Abort if the
  56        object already has notes (use `-f` to overwrite an
  57        existing note).
  58
  59copy::
  60        Copy the notes for the first object onto the second object.
  61        Abort if the second object already has notes, or if the first
  62        object has none (use -f to overwrite existing notes to the
  63        second object). This subcommand is equivalent to:
  64        `git notes add [-f] -C $(git notes list <from-object>) <to-object>`
  65+
  66In `\--stdin` mode, take lines in the format
  67+
  68----------
  69<from-object> SP <to-object> [ SP <rest> ] LF
  70----------
  71+
  72on standard input, and copy the notes from each <from-object> to its
  73corresponding <to-object>.  (The optional `<rest>` is ignored so that
  74the command can read the input given to the `post-rewrite` hook.)
  75
  76append::
  77        Append to the notes of an existing object (defaults to HEAD).
  78        Creates a new notes object if needed.
  79
  80edit::
  81        Edit the notes for a given object (defaults to HEAD).
  82
  83show::
  84        Show the notes for a given object (defaults to HEAD).
  85
  86remove::
  87        Remove the notes for a given object (defaults to HEAD).
  88        This is equivalent to specifying an empty note message to
  89        the `edit` subcommand.
  90
  91prune::
  92        Remove all notes for non-existing/unreachable objects.
  93
  94OPTIONS
  95-------
  96-f::
  97--force::
  98        When adding notes to an object that already has notes,
  99        overwrite the existing notes (instead of aborting).
 100
 101-m <msg>::
 102--message=<msg>::
 103        Use the given note message (instead of prompting).
 104        If multiple `-m` options are given, their values
 105        are concatenated as separate paragraphs.
 106        Lines starting with `#` and empty lines other than a
 107        single line between paragraphs will be stripped out.
 108
 109-F <file>::
 110--file=<file>::
 111        Take the note message from the given file.  Use '-' to
 112        read the note message from the standard input.
 113        Lines starting with `#` and empty lines other than a
 114        single line between paragraphs will be stripped out.
 115
 116-C <object>::
 117--reuse-message=<object>::
 118        Take the note message from the given blob object (for
 119        example, another note).
 120
 121-c <object>::
 122--reedit-message=<object>::
 123        Like '-C', but with '-c' the editor is invoked, so that
 124        the user can further edit the note message.
 125
 126--ref <ref>::
 127        Manipulate the notes tree in <ref>.  This overrides
 128        'GIT_NOTES_REF' and the "core.notesRef" configuration.  The ref
 129        is taken to be in `refs/notes/` if it is not qualified.
 130
 131
 132DISCUSSION
 133----------
 134
 135Commit notes are blobs containing extra information about an object
 136(usually information to supplement a commit's message).  These blobs
 137are taken from notes refs.  A notes ref is usually a branch which
 138contains "files" whose paths are the object names for the objects
 139they describe, with some directory separators included for performance
 140reasons footnote:[Permitted pathnames have the form
 141'ab'`/`'cd'`/`'ef'`/`'...'`/`'abcdef...': a sequence of directory
 142names of two hexadecimal digits each followed by a filename with the
 143rest of the object ID.].
 144
 145Every notes change creates a new commit at the specified notes ref.
 146You can therefore inspect the history of the notes by invoking, e.g.,
 147`git log -p notes/commits`.  Currently the commit message only records
 148which operation triggered the update, and the commit authorship is
 149determined according to the usual rules (see linkgit:git-commit[1]).
 150These details may change in the future.
 151
 152It is also permitted for a notes ref to point directly to a tree
 153object, in which case the history of the notes can be read with
 154`git log -p -g <refname>`.
 155
 156
 157EXAMPLES
 158--------
 159
 160You can use notes to add annotations with information that was not
 161available at the time a commit was written.
 162
 163------------
 164$ git notes add -m 'Tested-by: Johannes Sixt <j6t@kdbg.org>' 72a144e2
 165$ git show -s 72a144e

 169Notes:
 170    Tested-by: Johannes Sixt <j6t@kdbg.org>
 171------------
 172
 173In principle, a note is a regular Git blob, and any kind of
 174(non-)format is accepted.  You can binary-safely create notes from
 175arbitrary files using 'git hash-object':
 176
 177------------
 178$ cc *.c
 179$ blob=$(git hash-object -w a.out)
 180$ git notes --ref=built add -C "$blob" HEAD
 181------------
 182
 183Of course, it doesn't make much sense to display non-text-format notes
 184with 'git log', so if you use such notes, you'll probably need to write
 185some special-purpose tools to do something useful with them.
 186
 187
 188CONFIGURATION
 189-------------
 190
 191core.notesRef::
 192        Notes ref to read and manipulate instead of
 193        `refs/notes/commits`.  Must be an unabbreviated ref name.
 194        This setting can be overridden through the environment and
 195        command line.
 196
 197notes.displayRef::
 198        Which ref (or refs, if a glob or specified more than once), in
 199        addition to the default set by `core.notesRef` or
 200        'GIT_NOTES_REF', to read notes from when showing commit
 201        messages with the 'git log' family of commands.
 202        This setting can be overridden on the command line or by the
 203        'GIT_NOTES_DISPLAY_REF' environment variable.
 204        See linkgit:git-log[1].
 205
 206notes.rewrite.<command>::
 207        When rewriting commits with <command> (currently `amend` or
 208        `rebase`), if this variable is `false`, git will not copy
 209        notes from the original to the rewritten commit.  Defaults to
 210        `true`.  See also "`notes.rewriteRef`" below.
 211+
 212This setting can be overridden by the 'GIT_NOTES_REWRITE_REF'
 213environment variable.
 214
 215notes.rewriteMode::
 216        When copying notes during a rewrite, what to do if the target
 217        commit already has a note.  Must be one of `overwrite`,
 218        `concatenate`, and `ignore`.  Defaults to `concatenate`.
 219+
 220This setting can be overridden with the `GIT_NOTES_REWRITE_MODE`
 221environment variable.
 222
 223notes.rewriteRef::
 224        When copying notes during a rewrite, specifies the (fully
 225        qualified) ref whose notes should be copied.  May be a glob,
 226        in which case notes in all matching refs will be copied.  You
 227        may also specify this configuration several times.
 228+
 229Does not have a default value; you must configure this variable to
 230enable note rewriting.
 231+
 232Can be overridden with the 'GIT_NOTES_REWRITE_REF' environment variable.
 233
 234
 235ENVIRONMENT
 236-----------
 237
 238'GIT_NOTES_REF'::
 239        Which ref to manipulate notes from, instead of `refs/notes/commits`.
 240        This overrides the `core.notesRef` setting.
 241
 242'GIT_NOTES_DISPLAY_REF'::
 243        Colon-delimited list of refs or globs indicating which refs,
 244        in addition to the default from `core.notesRef` or
 245        'GIT_NOTES_REF', to read notes from when showing commit
 246        messages.
 247        This overrides the `notes.displayRef` setting.
 248+
 249A warning will be issued for refs that do not exist, but a glob that
 250does not match any refs is silently ignored.
 251
 252'GIT_NOTES_REWRITE_MODE'::
 253        When copying notes during a rewrite, what to do if the target
 254        commit already has a note.
 255        Must be one of `overwrite`, `concatenate`, and `ignore`.
 256        This overrides the `core.rewriteMode` setting.
 257
 258'GIT_NOTES_REWRITE_REF'::
 259        When rewriting commits, which notes to copy from the original
 260        to the rewritten commit.  Must be a colon-delimited list of
 261        refs or globs.
 262+
 263If not set in the environment, the list of notes to copy depends
 264on the `notes.rewrite.<command>` and `notes.rewriteRef` settings.
