17 | DESCRIPTION | |
18 | ----------- | |
19 | ||
20 | Iterate over all refs that match `<pattern>` and show them | |
21 | according to the given `<format>`, after sorting them according | |
d4040e0a | 22 | to the given set of `<key>`. If `<count>` is given, stop after |
23bfbb81 | 23 | showing that many refs. The interpolated values in `<format>` |
9f613ddd | 24 | can optionally be quoted as string literals in the specified |
1729fa98 | 25 | host language allowing their direct evaluation in that language. |
9f613ddd JH |
26 | |
27 | OPTIONS | |
28 | ------- | |
f7a32dd9 KD |
29 | <pattern>...:: |
30 | If one or more patterns are given, only refs are shown that | |
31 | match against at least one pattern, either using fnmatch(3) or | |
32 | literally, in the latter case matching completely or from the | |
33 | beginning up to a slash. | |
34 | ||
35 | --count=<count>:: | |
9f613ddd JH |
36 | By default the command shows all refs that match |
37 | `<pattern>`. This option makes it stop after showing | |
38 | that many refs. | |
39 | ||
f7a32dd9 | 40 | --sort=<key>:: |
9f613ddd JH |
41 | A field name to sort on. Prefix `-` to sort in |
42 | descending order of the value. When unspecified, | |
c0f6dc9b LW |
43 | `refname` is used. You may use the --sort=<key> option |
44 | multiple times, in which case the last key becomes the primary | |
45 | key. | |
9f613ddd | 46 | |
f7a32dd9 | 47 | --format=<format>:: |
e4933cee MG |
48 | A string that interpolates `%(fieldname)` from a ref being shown |
49 | and the object it points at. If `fieldname` | |
9f613ddd | 50 | is prefixed with an asterisk (`*`) and the ref points |
794b7e16 MG |
51 | at a tag object, use the value for the field in the object |
52 | which the tag object refers to (instead of the field in the tag object). | |
53 | When unspecified, `<format>` defaults to | |
ba7545ad JN |
54 | `%(objectname) SPC %(objecttype) TAB %(refname)`. |
55 | It also interpolates `%%` to `%`, and `%xx` where `xx` | |
56 | are hex digits interpolates to character with hex code | |
57 | `xx`; for example `%00` interpolates to `\0` (NUL), | |
58 | `%09` to `\t` (TAB) and `%0a` to `\n` (LF). | |
9f613ddd | 59 | |
dd61cc1c | 60 | --color[=<when>]:: |
0c88bf50 JK |
61 | Respect any colors specified in the `--format` option. The |
62 | `<when>` field must be one of `always`, `never`, or `auto` (if | |
63 | `<when>` is absent, behave as if `always` was given). | |
64 | ||
3240240f SB |
65 | --shell:: |
66 | --perl:: | |
67 | --python:: | |
68 | --tcl:: | |
9f613ddd JH |
69 | If given, strings that substitute `%(fieldname)` |
70 | placeholders are quoted as string literals suitable for | |
71 | the specified host language. This is meant to produce | |
72 | a scriptlet that can directly be `eval`ed. | |
73 | ||
3233d51d | 74 | --points-at=<object>:: |
d325406e | 75 | Only list refs which points at the given object. |
9f613ddd | 76 | |
3233d51d | 77 | --merged[=<object>]:: |
7c328348 | 78 | Only list refs whose tips are reachable from the |
21bf9339 | 79 | specified commit (HEAD if not specified). |
7c328348 | 80 | |
3233d51d | 81 | --no-merged[=<object>]:: |
7c328348 | 82 | Only list refs whose tips are not reachable from the |
21bf9339 | 83 | specified commit (HEAD if not specified). |
7c328348 | 84 | |
3233d51d | 85 | --contains[=<object>]:: |
8b5a3e98 | 86 | Only list refs which contain the specified commit (HEAD if not |
4a71109a KN |
87 | specified). |
88 | ||
3233d51d | 89 | --no-contains[=<object>]:: |
ac3f5a34 ÆAB |
90 | Only list refs which don't contain the specified commit (HEAD |
91 | if not specified). | |
92 | ||
3bb16a8b NTND |
93 | --ignore-case:: |
94 | Sorting and filtering refs are case insensitive. | |
95 | ||
9f613ddd JH |
96 | FIELD NAMES |
97 | ----------- | |
98 | ||
99 | Various values from structured fields in referenced objects can | |
100 | be used to interpolate into the resulting output, or as sort | |
101 | keys. | |
102 | ||
103 | For all objects, the following names can be used: | |
104 | ||
105 | refname:: | |
69057cf3 | 106 | The name of the ref (the part after $GIT_DIR/). |
7d66f21a | 107 | For a non-ambiguous short name of the ref append `:short`. |
2bb98169 | 108 | The option core.warnAmbiguousRefs is used to select the strict |
1a34728e KN |
109 | abbreviation mode. If `lstrip=<N>` (`rstrip=<N>`) is appended, strips `<N>` |
110 | slash-separated path components from the front (back) of the refname | |
111 | (e.g. `%(refname:lstrip=2)` turns `refs/tags/foo` into `foo` and | |
112 | `%(refname:rstrip=2)` turns `refs/tags/foo` into `refs`). | |
1a0ca5e3 | 113 | If `<N>` is a negative number, strip as many path components as |
1a34728e | 114 | necessary from the specified end to leave `-<N>` path components |
1a0ca5e3 | 115 | (e.g. `%(refname:lstrip=-2)` turns |
1a34728e KN |
116 | `refs/tags/foo` into `tags/foo` and `%(refname:rstrip=-1)` |
117 | turns `refs/tags/foo` into `refs`). When the ref does not have | |
1a0ca5e3 KN |
118 | enough components, the result becomes an empty string if |
119 | stripping with positive <N>, or it becomes the full refname if | |
120 | stripping with negative <N>. Neither is an error. | |
44a6b6ce | 121 | + |
c30d4f1b | 122 | `strip` can be used as a synonym to `lstrip`. |
9f613ddd JH |
123 | |
124 | objecttype:: | |
125 | The type of the object (`blob`, `tree`, `commit`, `tag`). | |
126 | ||
127 | objectsize:: | |
0b444cdb | 128 | The size of the object (the same as 'git cat-file -s' reports). |
59012fe5 OT |
129 | Append `:disk` to get the size, in bytes, that the object takes up on |
130 | disk. See the note about on-disk sizes in the `CAVEATS` section below. | |
9f613ddd JH |
131 | objectname:: |
132 | The object name (aka SHA-1). | |
67687fea | 133 | For a non-ambiguous abbreviation of the object name append `:short`. |
42d0eb05 KN |
134 | For an abbreviation of the object name with desired length append |
135 | `:short=<length>`, where the minimum length is MINIMUM_ABBREV. The | |
136 | length may be exceeded to ensure unique object names. | |
59012fe5 OT |
137 | deltabase:: |
138 | This expands to the object name of the delta base for the | |
139 | given object, if it is stored as a delta. Otherwise it | |
140 | expands to the null object name (all zeroes). | |
9f613ddd | 141 | |
8cae19d9 JK |
142 | upstream:: |
143 | The name of a local ref which can be considered ``upstream'' | |
1a34728e KN |
144 | from the displayed ref. Respects `:short`, `:lstrip` and |
145 | `:rstrip` in the same way as `refname` above. Additionally | |
146 | respects `:track` to show "[ahead N, behind M]" and | |
147 | `:trackshort` to show the terse version: ">" (ahead), "<" | |
148 | (behind), "<>" (ahead and behind), or "=" (in sync). `:track` | |
149 | also prints "[gone]" whenever unknown upstream ref is | |
150 | encountered. Append `:track,nobracket` to show tracking | |
cc72385f JS |
151 | information without brackets (i.e "ahead N, behind M"). |
152 | + | |
9700fae5 W |
153 | For any remote-tracking branch `%(upstream)`, `%(upstream:remotename)` |
154 | and `%(upstream:remoteref)` refer to the name of the remote and the | |
155 | name of the tracked remote ref, respectively. In other words, the | |
156 | remote-tracking branch can be updated explicitly and individually by | |
157 | using the refspec `%(upstream:remoteref):%(upstream)` to fetch from | |
158 | `%(upstream:remotename)`. | |
cc72385f JS |
159 | + |
160 | Has no effect if the ref does not have tracking information associated | |
161 | with it. All the options apart from `nobracket` are mutually exclusive, | |
162 | but if used together the last option is selected. | |
8cae19d9 | 163 | |
29bc8850 | 164 | push:: |
3ba308cb | 165 | The name of a local ref which represents the `@{push}` |
17938f17 | 166 | location for the displayed ref. Respects `:short`, `:lstrip`, |
9700fae5 W |
167 | `:rstrip`, `:track`, `:trackshort`, `:remotename`, and `:remoteref` |
168 | options as `upstream` does. Produces an empty string if no `@{push}` | |
169 | ref is configured. | |
29bc8850 | 170 | |
7a48b832 RR |
171 | HEAD:: |
172 | '*' if HEAD matches current ref (the checked out branch), ' ' | |
173 | otherwise. | |
174 | ||
fddb74c9 | 175 | color:: |
5d3d0681 JK |
176 | Change output color. Followed by `:<colorname>`, where color |
177 | names are described under Values in the "CONFIGURATION FILE" | |
178 | section of linkgit:git-config[1]. For example, | |
179 | `%(color:bold red)`. | |
fddb74c9 | 180 | |
ce592082 KN |
181 | align:: |
182 | Left-, middle-, or right-align the content between | |
395fb8f9 KN |
183 | %(align:...) and %(end). The "align:" is followed by |
184 | `width=<width>` and `position=<position>` in any order | |
185 | separated by a comma, where the `<position>` is either left, | |
186 | right or middle, default being left and `<width>` is the total | |
187 | length of the content with alignment. For brevity, the | |
188 | "width=" and/or "position=" prefixes may be omitted, and bare | |
189 | <width> and <position> used instead. For instance, | |
190 | `%(align:<width>,<position>)`. If the contents length is more | |
191 | than the width then no alignment is performed. If used with | |
bcf9626a | 192 | `--quote` everything in between %(align:...) and %(end) is |
395fb8f9 KN |
193 | quoted, but if nested then only the topmost level performs |
194 | quoting. | |
ce592082 | 195 | |
c58492d4 KN |
196 | if:: |
197 | Used as %(if)...%(then)...%(end) or | |
198 | %(if)...%(then)...%(else)...%(end). If there is an atom with | |
199 | value or string literal after the %(if) then everything after | |
200 | the %(then) is printed, else if the %(else) atom is used, then | |
201 | everything after %(else) is printed. We ignore space when | |
202 | evaluating the string before %(then), this is useful when we | |
203 | use the %(HEAD) atom which prints either "*" or " " and we | |
204 | want to apply the 'if' condition only on the 'HEAD' ref. | |
4f3e3b37 KN |
205 | Append ":equals=<string>" or ":notequals=<string>" to compare |
206 | the value between the %(if:...) and %(then) atoms with the | |
207 | given string. | |
c58492d4 | 208 | |
a7984101 KN |
209 | symref:: |
210 | The ref which the given symbolic ref refers to. If not a | |
1a34728e KN |
211 | symbolic ref, nothing is printed. Respects the `:short`, |
212 | `:lstrip` and `:rstrip` options in the same way as `refname` | |
213 | above. | |
a7984101 | 214 | |
2582083f NB |
215 | worktreepath:: |
216 | The absolute path to the worktree in which the ref is checked | |
217 | out, if it is checked out in any linked worktree. Empty string | |
218 | otherwise. | |
219 | ||
9f613ddd JH |
220 | In addition to the above, for commit and tag objects, the header |
221 | field names (`tree`, `parent`, `object`, `type`, and `tag`) can | |
222 | be used to specify the value in the header field. | |
26bc0aaf | 223 | Fields `tree` and `parent` can also be used with modifier `:short` and |
837adb10 | 224 | `:short=<length>` just like `objectname`. |
9f613ddd | 225 | |
e914ef0d EW |
226 | For commit and tag objects, the special `creatordate` and `creator` |
227 | fields will correspond to the appropriate date or name-email-date tuple | |
228 | from the `committer` or `tagger` fields depending on the object type. | |
229 | These are intended for working on a mix of annotated and lightweight tags. | |
230 | ||
9f613ddd JH |
231 | Fields that have name-email-date tuple as its value (`author`, |
232 | `committer`, and `tagger`) can be suffixed with `name`, `email`, | |
b82445dc HV |
233 | and `date` to extract the named component. For email fields (`authoremail`, |
234 | `committeremail` and `taggeremail`), `:trim` can be appended to get the email | |
235 | without angle brackets, and `:localpart` to get the part before the `@` symbol | |
236 | out of the trimmed email. | |
9f613ddd | 237 | |
9fcc9caf CC |
238 | The message in a commit or a tag object is `contents`, from which |
239 | `contents:<part>` can be used to extract various parts out of: | |
240 | ||
b6839fda CC |
241 | contents:size:: |
242 | The size in bytes of the commit or tag message. | |
243 | ||
9fcc9caf CC |
244 | contents:subject:: |
245 | The first paragraph of the message, which typically is a | |
246 | single line, is taken as the "subject" of the commit or the | |
247 | tag message. | |
905f0a4e HV |
248 | Instead of `contents:subject`, field `subject` can also be used to |
249 | obtain same results. `:sanitize` can be appended to `subject` for | |
250 | subject line suitable for filename. | |
9fcc9caf CC |
251 | |
252 | contents:body:: | |
253 | The remainder of the commit or the tag message that follows | |
254 | the "subject". | |
255 | ||
256 | contents:signature:: | |
257 | The optional GPG signature of the tag. | |
258 | ||
259 | contents:lines=N:: | |
260 | The first `N` lines of the message. | |
261 | ||
b1d31c89 | 262 | Additionally, the trailers as interpreted by linkgit:git-interpret-trailers[1] |
ced1f08b | 263 | are obtained as `trailers` (or by using the historical alias |
67a20a00 TB |
264 | `contents:trailers`). Non-trailer lines from the trailer block can be omitted |
265 | with `trailers:only`. Whitespace-continuations can be removed from trailers so | |
266 | that each trailer appears on a line by itself with its full content with | |
267 | `trailers:unfold`. Both can be used together as `trailers:unfold,only`. | |
9f613ddd | 268 | |
e914ef0d EW |
269 | For sorting purposes, fields with numeric values sort in numeric order |
270 | (`objectsize`, `authordate`, `committerdate`, `creatordate`, `taggerdate`). | |
9f613ddd JH |
271 | All other fields are used to sort in their byte-value order. |
272 | ||
90c00408 KN |
273 | There is also an option to sort by versions, this can be done by using |
274 | the fieldname `version:refname` or its alias `v:refname`. | |
275 | ||
9f613ddd JH |
276 | In any case, a field name that refers to a field inapplicable to |
277 | the object referred by the ref does not cause an error. It | |
278 | returns an empty string instead. | |
279 | ||
d392e712 | 280 | As a special case for the date-type fields, you may specify a format for |
8f50d263 | 281 | the date by adding `:` followed by date format name (see the |
1cca17df | 282 | values the `--date` option to linkgit:git-rev-list[1] takes). |
d392e712 | 283 | |
c58492d4 KN |
284 | Some atoms like %(align) and %(if) always require a matching %(end). |
285 | We call them "opening atoms" and sometimes denote them as %($open). | |
286 | ||
287 | When a scripting language specific quoting is in effect, everything | |
288 | between a top-level opening atom and its matching %(end) is evaluated | |
289 | according to the semantics of the opening atom and only its result | |
290 | from the top-level is quoted. | |

395 | CAVEATS |
396 | ------- | |
397 | ||
398 | Note that the sizes of objects on disk are reported accurately, but care | |
399 | should be taken in drawing conclusions about which refs or objects are | |
400 | responsible for disk usage. The size of a packed non-delta object may be | |
401 | much larger than the size of objects which delta against it, but the | |
402 | choice of which object is the base and which is the delta is arbitrary | |
