| <p>With no arguments, shows the status of existing submodules. Several |
| subcommands are available to perform operations on the submodules.</p> |
| </div> |
| <div class="dlist"> |
| <dl> |
| <dt class="hdlist1"><code>add</code> [<code>-b</code> <em><branch></em>] [<code>-f</code> | <code>--force</code>] [<code>--name</code> <em><name></em>] [<code>--reference</code> <em><repository></em>] [<code>--ref-format</code> <em><format></em>] [<code>--depth</code> <em><depth></em>] [<code>--</code>] <em><repository></em> [<em><path></em>]</dt> |
| <dd> |
| <p>Add the given repository as a submodule at the given path |
| to the changeset to be committed next to the current |
| project: the current project is termed the "superproject".</p> |
| <div class="paragraph"> |
| <p><em><repository></em> is the URL of the new submodule’s <code>origin</code> repository. |
| This may be either an absolute URL, or (if it begins with .<code>/</code> |
| or <code>..</code><code>/</code>), the location relative to the superproject’s default remote |
| repository (Please note that to specify a repository <code>foo.git</code> |
| which is located right next to a superproject <code>bar.git</code>, you’ll |
| have to use <code>..</code><code>/foo.git</code> instead of .<code>/foo.git</code> - as one might expect |
| when following the rules for relative URLs - because the evaluation |
| of relative URLs in Git is identical to that of relative directories).</p> |
| </div> |
| <div class="paragraph"> |
| <p>The default remote is the remote of the remote-tracking branch |
| of the current branch. If no such remote-tracking branch exists or |
| the <code>HEAD</code> is detached, <code>origin</code> is assumed to be the default remote. |
| If the superproject doesn’t have a default remote configured |
| the superproject is its own authoritative upstream and the current |
| working directory is used instead.</p> |
| </div> |
| <div class="paragraph"> |
| <p>The optional argument <em><path></em> is the relative location for the cloned |
| submodule to exist in the superproject. If <em><path></em> is not given, the |
| canonical part of the source repository is used (<code>repo</code> for |
| <code>/path/to/repo.git</code> and <code>foo</code> for <code>host.xz:foo/.git</code>). If <em><path></em> |
| exists and is already a valid Git repository, then it is staged |
| for commit without cloning. The <em><path></em> is also used as the submodule’s |
| logical name in its configuration entries unless <code>--name</code> <em><name></em> is used |
| to specify a logical name.</p> |
| </div> |
| <div class="paragraph"> |
| <p>The given URL is recorded into .<code>gitmodules</code> for use by subsequent users |
| cloning the superproject. If the URL is given relative to the |
| superproject’s repository, the presumption is the superproject and |
| submodule repositories will be kept together in the same relative |
| location, and only the superproject’s URL needs to be provided. |
| git-submodule will correctly locate the submodule using the relative |
| URL in .<code>gitmodules</code>.</p> |
| </div> |
| <div class="paragraph"> |
| <p>If <code>--ref-format</code> <em><format></em> is specified, the ref storage format of newly |
| cloned submodules will be set accordingly.</p> |
| </div> |
| </dd> |
| <dt class="hdlist1"><code>status</code> [<code>--cached</code>] [<code>--recursive</code>] [<code>--</code>] [<em><path></em>...]</dt> |
| <dd> |
| <p>Show the status of the submodules. This will print the SHA-1 of the |
| currently checked out commit for each submodule, along with the |
| submodule path and the output of <a href="git-describe.html">git-describe(1)</a> for the |
| SHA-1. Each SHA-1 will possibly be prefixed with <code>-</code> if the submodule is |
| not initialized, <code>+</code> if the currently checked out submodule commit |
| does not match the SHA-1 found in the index of the containing |
| repository and <code>U</code> if the submodule has merge conflicts.</p> |
| <div class="paragraph"> |
| <p>If <code>--cached</code> is specified, this command will instead print the SHA-1 |
| recorded in the superproject for each submodule.</p> |
| </div> |
| <div class="paragraph"> |
| <p>If <code>--recursive</code> is specified, this command will recurse into nested |
| submodules, and show their status as well.</p> |
| </div> |
| <div class="paragraph"> |
| <p>If you are only interested in changes of the currently initialized |
| submodules with respect to the commit recorded in the index or the <code>HEAD</code>, |
| <a href="git-status.html">git-status(1)</a> and <a href="git-diff.html">git-diff(1)</a> will provide that information |
| too (and can also report changes to a submodule’s work tree).</p> |
| </div> |
| </dd> |
| <dt class="hdlist1"><code>init</code> [<code>--</code>] [<em><path></em>...]</dt> |
| <dd> |
| <p>Initialize the submodules recorded in the index (which were |
| added and committed elsewhere) by setting <code>submodule.$name.url</code> |
| in .<code>git/config</code>, using the same setting from .<code>gitmodules</code> as |
| a template. If the URL is relative, it will be resolved using |
| the default remote. If there is no default remote, the current |
| repository will be assumed to be upstream.</p> |
| <div class="paragraph"> |
| <p>Optional <em><path></em> arguments limit which submodules will be initialized. |
| If no path is specified and submodule.active has been configured, submodules |
| configured to be active will be initialized, otherwise all submodules are |
| initialized.</p> |
| </div> |
| <div class="paragraph"> |
| <p>It will also copy the value of <code>submodule.$name.update</code>, if present in |
| the .<code>gitmodules</code> file, to .<code>git/config</code>, but (1) this command does not |
| alter existing information in .<code>git/config</code>, and (2) <code>submodule.$name.update</code> |
| that is set to a custom command is <strong>not</strong> copied for security reasons.</p> |
| </div> |
| <div class="paragraph"> |
| <p>You can then customize the submodule clone URLs in .<code>git/config</code> |
| for your local setup and proceed to <code>git</code> <code>submodule</code> <code>update</code>; |
| you can also just use <code>git</code> <code>submodule</code> <code>update</code> <code>--init</code> without |
| the explicit <code>init</code> step if you do not intend to customize |
| any submodule locations.</p> |
| </div> |
| <div class="paragraph"> |
| <p>See the add subcommand for the definition of default remote.</p> |
| </div> |
| </dd> |
| <dt class="hdlist1"><code>deinit</code> [<code>-f</code> | <code>--force</code>] (<code>--all</code>|[<code>--</code>] <em><path></em><code>...</code>)</dt> |
| <dd> |
| <p>Unregister the given submodules, i.e. remove the whole |
| <code>submodule.$name</code> section from .git/config together with their work |
| tree. Further calls to <code>git</code> <code>submodule</code> <code>update</code>, <code>git</code> <code>submodule</code> <code>foreach</code> |
| and <code>git</code> <code>submodule</code> <code>sync</code> will skip any unregistered submodules until |
| they are initialized again, so use this command if you don’t want to |
| have a local checkout of the submodule in your working tree anymore.</p> |
| <div class="paragraph"> |
| <p>When the command is run without pathspec, it errors out, |
| instead of deinit-ing everything, to prevent mistakes.</p> |
| </div> |
| <div class="paragraph"> |
| <p>If <code>--force</code> is specified, the submodule’s working tree will |
| be removed even if it contains local modifications.</p> |
| </div> |
| <div class="paragraph"> |
| <p>If you really want to remove a submodule from the repository and commit |
| that use <a href="git-rm.html">git-rm(1)</a> instead. See <a href="gitsubmodules.html">gitsubmodules(7)</a> for removal |
| options.</p> |
| </div> |
| </dd> |
