DESCRIPTION
|
|
|
|
-----------
|
|
|
|
|
|
|
|
Iterate over all refs that match `<pattern>` and show them
|
|
|
|
according to the given `<format>`, after sorting them according
|
2008-09-01 21:02:09 +00:00
|
|
|
to the given set of `<key>`. If `<count>` is given, stop after
|
2007-01-17 15:32:41 +00:00
|
|
|
showing that many refs. The interpolated values in `<format>`
|
2006-09-15 20:30:02 +00:00
|
|
|
can optionally be quoted as string literals in the specified
|
2006-09-21 09:19:17 +00:00
|
|
|
host language allowing their direct evaluation in that language.

OPTIONS
|
|
|
|
-------
|
2017-09-11 19:33:38 +00:00
|
|
|
<pattern>...::
|
|
|
|
If one or more patterns are given, only refs are shown that
|
|
|
|
match against at least one pattern, either using fnmatch(3) or
|
|
|
|
literally, in the latter case matching completely or from the
|
|
|
|
beginning up to a slash.
|
|
|
|
|
|
|
|
--count=<count>::
|
2006-09-15 20:30:02 +00:00
|
|
|
By default the command shows all refs that match
|
|
|
|
`<pattern>`. This option makes it stop after showing
|
|
|
|
that many refs.
|
|
|
|
|
2017-09-11 19:33:38 +00:00
|
|
|
--sort=<key>::
|
2006-09-15 20:30:02 +00:00
|
|
|
A field name to sort on. Prefix `-` to sort in
|
|
|
|
descending order of the value. When unspecified,
|
2008-06-05 21:01:38 +00:00
|
|
|
`refname` is used. You may use the --sort=<key> option
|
|
|
|
multiple times, in which case the last key becomes the primary
|
|
|
|
key.
|
2006-09-15 20:30:02 +00:00
|
|
|
|
2017-09-11 19:33:38 +00:00
|
|
|
--format=<format>::
|
2017-08-18 14:51:22 +00:00
|
|
|
A string that interpolates `%(fieldname)` from a ref being shown
|
|
|
|
and the object it points at. If `fieldname`
|
2006-09-15 20:30:02 +00:00
|
|
|
is prefixed with an asterisk (`*`) and the ref points
|
2017-08-18 14:51:23 +00:00
|
|
|
at a tag object, use the value for the field in the object
|
|
|
|
which the tag object refers to (instead of the field in the tag object).
|
|
|
|
When unspecified, `<format>` defaults to
|
2006-10-28 17:30:05 +00:00
|
|
|
`%(objectname) SPC %(objecttype) TAB %(refname)`.
|
|
|
|
It also interpolates `%%` to `%`, and `%xx` where `xx`
|
|
|
|
are hex digits interpolates to character with hex code
|
|
|
|
`xx`; for example `%00` interpolates to `\0` (NUL),
|
|
|
|
`%09` to `\t` (TAB) and `%0a` to `\n` (LF).

|
--color[=<when>]::
|
2017-10-03 13:45:47 +00:00
|
|
|
Respect any colors specified in the `--format` option. The
|
|
|
|
`<when>` field must be one of `always`, `never`, or `auto` (if
|
|
|
|
`<when>` is absent, behave as if `always` was given).

|
|
If given, strings that substitute `%(fieldname)`
|
|
|
|
placeholders are quoted as string literals suitable for
|
|
|
|
the specified host language. This is meant to produce
|
|

a scriptlet that can directly be `eval`ed.

ref-filter: add --no-contains option to tag/branch/for-each-ref
Change the tag, branch & for-each-ref commands to have a --no-contains
option in addition to their longstanding --contains options.
This allows for finding the last-good rollout tag given a known-bad
<commit>. Given a hypothetically bad commit cf5c7253e0, the git
version to revert to can be found with this hacky two-liner:
(git tag -l 'v[0-9]*'; git tag -l --contains cf5c7253e0 'v[0-9]*') |
sort | uniq -c | grep -E '^ *1 ' | awk '{print $2}' | tail -n 10
With this new --no-contains option the same can be achieved with:
git tag -l --no-contains cf5c7253e0 'v[0-9]*' | sort | tail -n 10
As the filtering machinery is shared between the tag, branch &
for-each-ref commands, implement this for those commands too. A
practical use for this with "branch" is e.g. finding branches which
were branched off between v2.8.0 and v2.10.0:
git branch --contains v2.8.0 --no-contains v2.10.0
The "describe" command also has a --contains option, but its semantics
are unrelated to what tag/branch/for-each-ref use --contains for. A
--no-contains option for "describe" wouldn't make any sense, other
than being exactly equivalent to not supplying --contains at all,
which would be confusing at best.
Add a --without option to "tag" as an alias for --no-contains, for
consistency with --with and --contains. The --with option is
undocumented, and possibly the only user of it is
Junio (<xmqqefy71iej.fsf@gitster.mtv.corp.google.com>). But it's
trivial to support, so let's do that.
The additions to the the test suite are inverse copies of the
corresponding --contains tests. With this change --no-contains for
tag, branch & for-each-ref is just as well tested as the existing
--contains option.
In addition to those tests, add a test for "tag" which asserts that
--no-contains won't find tree/blob tags, which is slightly
unintuitive, but consistent with how --contains works & is documented.

FIELD NAMES
|
|
|
|
-----------
|
|
|
|
|
|
|
|
Various values from structured fields in referenced objects can
|
|
|
|
be used to interpolate into the resulting output, or as sort
|
|
|
|
keys.
|
|
|
|
|
|
|
|
For all objects, the following names can be used:
|
|
|
|
|
|
|
|
refname::
|
2007-02-05 19:58:47 +00:00
|
|
|
The name of the ref (the part after $GIT_DIR/).
|
2008-09-05 21:16:23 +00:00
|
|
|
For a non-ambiguous short name of the ref append `:short`.
|
2009-04-13 10:25:47 +00:00
|
|
|
The option core.warnAmbiguousRefs is used to select the strict
|
2017-01-10 08:49:49 +00:00
|
|
|
abbreviation mode. If `lstrip=<N>` (`rstrip=<N>`) is appended, strips `<N>`
|
|
|
|
slash-separated path components from the front (back) of the refname
|
|
|
|
(e.g. `%(refname:lstrip=2)` turns `refs/tags/foo` into `foo` and
|
|
|
|
`%(refname:rstrip=2)` turns `refs/tags/foo` into `refs`).
|
2017-01-10 08:49:48 +00:00
|
|
|
If `<N>` is a negative number, strip as many path components as
|
2017-01-10 08:49:49 +00:00
|
|
|
necessary from the specified end to leave `-<N>` path components
|
2017-01-10 08:49:48 +00:00
|
|
|
(e.g. `%(refname:lstrip=-2)` turns
|
2017-01-10 08:49:49 +00:00
|
|
|
`refs/tags/foo` into `tags/foo` and `%(refname:rstrip=-1)`
|
|
|
|
turns `refs/tags/foo` into `refs`). When the ref does not have
|
2017-01-10 08:49:48 +00:00
|
|
|
enough components, the result becomes an empty string if
|
|
|
|
stripping with positive <N>, or it becomes the full refname if
|
|
|
|
stripping with negative <N>. Neither is an error.
|
2017-02-07 19:50:34 +00:00
|
|
|
+
|
2018-04-05 17:20:26 +00:00
|
|
|
`strip` can be used as a synonym to `lstrip`.
|
2006-09-15 20:30:02 +00:00
|
|
|
|
|
|
|
objecttype::
|
|
|
|
The type of the object (`blob`, `tree`, `commit`, `tag`).
|
|
|
|
|
|
|
|
objectsize::
|
2010-01-09 23:33:00 +00:00
|
|
|
The size of the object (the same as 'git cat-file -s' reports).
|
2018-12-24 13:24:30 +00:00
|
|
|
Append `:disk` to get the size, in bytes, that the object takes up on
|
|
|
|
disk. See the note about on-disk sizes in the `CAVEATS` section below.
|
2006-09-15 20:30:02 +00:00
|
|
|
objectname::
|
|
|
|
The object name (aka SHA-1).
|
2010-05-13 12:31:46 +00:00
|
|
|
For a non-ambiguous abbreviation of the object name append `:short`.
|
2017-01-10 08:49:37 +00:00
|
|
|
For an abbreviation of the object name with desired length append
|
|
|
|
`:short=<length>`, where the minimum length is MINIMUM_ABBREV. The
|
|
|
|
length may be exceeded to ensure unique object names.
|
2018-12-24 13:24:30 +00:00
|
|
|
deltabase::
|
|
|
|
This expands to the object name of the delta base for the
|
|
|
|
given object, if it is stored as a delta. Otherwise it
|
|
|
|
expands to the null object name (all zeroes).
|
2006-09-15 20:30:02 +00:00
|
|
|
|
2009-04-07 07:09:39 +00:00
|
|
|
upstream::
|
|
|
|
The name of a local ref which can be considered ``upstream''
|
2017-01-10 08:49:49 +00:00
|
|
|
from the displayed ref. Respects `:short`, `:lstrip` and
|
|
|
|
`:rstrip` in the same way as `refname` above. Additionally
|
|
|
|
respects `:track` to show "[ahead N, behind M]" and
|
|
|
|
`:trackshort` to show the terse version: ">" (ahead), "<"
|
|
|
|
(behind), "<>" (ahead and behind), or "=" (in sync). `:track`
|
|
|
|
also prints "[gone]" whenever unknown upstream ref is
|
|
|
|
encountered. Append `:track,nobracket` to show tracking
|
2017-10-05 12:19:09 +00:00
|
|
|
information without brackets (i.e "ahead N, behind M").
|
|
|
|
+
|
2017-11-07 16:31:08 +00:00
|
|
|
For any remote-tracking branch `%(upstream)`, `%(upstream:remotename)`
|
|
|
|
and `%(upstream:remoteref)` refer to the name of the remote and the
|
|
|
|
name of the tracked remote ref, respectively. In other words, the
|
|
|
|
remote-tracking branch can be updated explicitly and individually by
|
|
|
|
using the refspec `%(upstream:remoteref):%(upstream)` to fetch from
|
|
|
|
`%(upstream:remotename)`.
|
2017-10-05 12:19:09 +00:00
|
|
|
+
|
|
|
|
Has no effect if the ref does not have tracking information associated
|
|
|
|
with it. All the options apart from `nobracket` are mutually exclusive,
|
|
|
|
but if used together the last option is selected.

|
|
|
push::
|
2017-01-10 08:49:45 +00:00
|
|
|
The name of a local ref which represents the `@{push}`
|
2017-01-10 08:49:46 +00:00
|
|
|
location for the displayed ref. Respects `:short`, `:lstrip`,
|
2017-11-07 16:31:08 +00:00
|
|
|
`:rstrip`, `:track`, `:trackshort`, `:remotename`, and `:remoteref`
|
|
|
|
options as `upstream` does. Produces an empty string if no `@{push}`
|
|
|
|
ref is configured.

HEAD::
|

'*' if HEAD matches current ref (the checked out branch), ' '
|
|
|
|
otherwise.
|
|
|
|
|
2013-11-18 17:39:12 +00:00
|
|
|
color::
|
2017-07-13 14:56:21 +00:00
|
|
|
Change output color. Followed by `:<colorname>`, where color
|
|
|
|
names are described under Values in the "CONFIGURATION FILE"
|
|
|
|
section of linkgit:git-config[1]. For example,
|
|
|
|
`%(color:bold red)`.

|
2015-09-11 15:03:07 +00:00
|
|
|
align::
|
|
|
|
Left-, middle-, or right-align the content between
|
2016-02-17 18:06:16 +00:00
|
|
|
%(align:...) and %(end). The "align:" is followed by
|
|
|
|
`width=<width>` and `position=<position>` in any order
|
|
|
|
separated by a comma, where the `<position>` is either left,
|
|
|
|
right or middle, default being left and `<width>` is the total
|
|
|
|
length of the content with alignment. For brevity, the
|
|
|
|
"width=" and/or "position=" prefixes may be omitted, and bare
|
|
|
|
<width> and <position> used instead. For instance,
|
|
|
|
`%(align:<width>,<position>)`. If the contents length is more
|
|
|
|
than the width then no alignment is performed. If used with
|
2016-06-28 11:40:11 +00:00
|
|
|
`--quote` everything in between %(align:...) and %(end) is
|
2016-02-17 18:06:16 +00:00
|
|
|
quoted, but if nested then only the topmost level performs
|
|
|
|
quoting.

|
|
|
|
2017-01-10 08:49:34 +00:00
|
|
|
if::
|
|
|
|
Used as %(if)...%(then)...%(end) or
|
|
|
|
%(if)...%(then)...%(else)...%(end). If there is an atom with
|
|
|
|
value or string literal after the %(if) then everything after
|
|
|
|
the %(then) is printed, else if the %(else) atom is used, then
|
|
|
|
everything after %(else) is printed. We ignore space when
|
|
|
|
evaluating the string before %(then), this is useful when we
|
|
|
|
use the %(HEAD) atom which prints either "*" or " " and we
|
|
|
|
want to apply the 'if' condition only on the 'HEAD' ref.
|
2017-01-10 08:49:36 +00:00
|
|
|
Append ":equals=<string>" or ":notequals=<string>" to compare

the value between the %(if:...) and %(then) atoms with the

symref::
|
|
|
|
The ref which the given symbolic ref refers to. If not a

2017-01-10 08:49:49 +00:00
|
|
|
symbolic ref, nothing is printed. Respects the `:short`,

`:lstrip` and `:rstrip` options in the same way as `refname`

|
above.

worktreepath::
|
|
|
|
The absolute path to the worktree in which the ref is checked
|
|
|
|
out, if it is checked out in any linked worktree. Empty string
|
|
|
|
otherwise.

|
|
|
In addition to the above, for commit and tag objects, the header
|
|
|
|
field names (`tree`, `parent`, `object`, `type`, and `tag`) can
|
|
|
|
be used to specify the value in the header field.
|
|
|
|
|
2016-01-05 03:51:57 +00:00
|
|
|
For commit and tag objects, the special `creatordate` and `creator`
|
|
|
|
fields will correspond to the appropriate date or name-email-date tuple
|
|
|
|
from the `committer` or `tagger` fields depending on the object type.
|
|
|
|
These are intended for working on a mix of annotated and lightweight tags.
|
|
|
|
|
2006-09-15 20:30:02 +00:00
|
|
|
Fields that have name-email-date tuple as its value (`author`,
|
|
|
|
`committer`, and `tagger`) can be suffixed with `name`, `email`,
|
|
|
|
and `date` to extract the named component.
|
|
|
|
|
2011-09-07 17:46:08 +00:00
|
|
|
The complete message in a commit and tag object is `contents`.
|
2012-09-13 22:27:09 +00:00
|
|
|
Its first line is `contents:subject`, where subject is the concatenation
|
|
|
|
of all lines of the commit message up to the first blank line. The next
|
2017-10-01 16:18:50 +00:00
|
|
|
line is `contents:body`, where body is all of the lines after the first
|
2015-09-11 15:04:16 +00:00
|
|
|
blank line. The optional GPG signature is `contents:signature`. The
|
|
|
|
first `N` lines of the message is obtained using `contents:lines=N`.
|
2016-11-19 00:58:15 +00:00
|
|
|
Additionally, the trailers as interpreted by linkgit:git-interpret-trailers[1]
|
2017-10-01 16:18:50 +00:00
|
|
|
are obtained as `trailers` (or by using the historical alias
|
2017-10-02 05:25:23 +00:00
|
|
|
`contents:trailers`). Non-trailer lines from the trailer block can be omitted
|
|
|
|
with `trailers:only`. Whitespace-continuations can be removed from trailers so
|
|
|
|
that each trailer appears on a line by itself with its full content with
|
|
|
|
`trailers:unfold`. Both can be used together as `trailers:unfold,only`.

2016-01-05 03:51:57 +00:00
|
|
|
For sorting purposes, fields with numeric values sort in numeric order
|
|
|
|
(`objectsize`, `authordate`, `committerdate`, `creatordate`, `taggerdate`).
|
2006-09-15 20:30:02 +00:00
|
|
|
All other fields are used to sort in their byte-value order.
|
|
|
|
|
2015-09-10 15:48:25 +00:00
|
|
|
There is also an option to sort by versions, this can be done by using
|
|
|
|
the fieldname `version:refname` or its alias `v:refname`.
|
|
|
|
|
2006-09-15 20:30:02 +00:00
|
|
|
In any case, a field name that refers to a field inapplicable to
|
|
|
|
the object referred by the ref does not cause an error. It
|
|
|
|
returns an empty string instead.
|
|
|
|
|
2007-09-28 14:17:45 +00:00
|
|
|
As a special case for the date-type fields, you may specify a format for
|
2015-09-03 21:48:53 +00:00
|
|
|
the date by adding `:` followed by date format name (see the
|
2016-05-04 17:36:24 +00:00
|
|
|
values the `--date` option to linkgit:git-rev-list[1] takes).

|
|
|
|
2017-01-10 08:49:34 +00:00
|
|
|
Some atoms like %(align) and %(if) always require a matching %(end).
|
|
|
|
We call them "opening atoms" and sometimes denote them as %($open).
|
|
|
|
|
|
|
|
When a scripting language specific quoting is in effect, everything
|
|
|
|
between a top-level opening atom and its matching %(end) is evaluated
|
|
|
|
according to the semantics of the opening atom and only its result
|
|
|
|
from the top-level is quoted.

|
Note that the sizes of objects on disk are reported accurately, but care
|
|
|
|
should be taken in drawing conclusions about which refs or objects are
|
|
|
|
responsible for disk usage. The size of a packed non-delta object may be
|
|
|
|
much larger than the size of objects which delta against it, but the
|
|
|
|
choice of which object is the base and which is the delta is arbitrary
|
|
|
|
and is subject to change during a repack.
|
|
|
|
|
|
|
|
Note also that multiple copies of an object may be present in the object
|
|
|
|
database; in this case, it is undefined which copy's size or delta base
|
|
|
|
will be reported.
