DESCRIPTION
|
|
-----------
|
|
Inspects, updates and manages submodules.
|
|
|
|
For more information about submodules, see linkgit:gitsubmodules[7].
|
|
|
|
COMMANDS
|
|
--------
|
|
add [-b <branch>] [-f|--force] [--name <name>] [--reference <repository>] [--depth <depth>] [--] <repository> [<path>]::
|
|
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".
|
|
+
|
|
<repository> is the URL of the new submodule's origin repository.
|
|
This may be either an absolute URL, or (if it begins with ./
|
|
or ../), the location relative to the superproject's default remote
|
|
repository (Please note that to specify a repository 'foo.git'
|
|
which is located right next to a superproject 'bar.git', you'll
|
|
have to use '../foo.git' instead of './foo.git' - 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).
|
|
+
|
|
The default remote is the remote of the remote tracking branch
|
|
of the current branch. If no such remote tracking branch exists or
|
|
the HEAD is detached, "origin" 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.
|
|
+
|
|
The optional argument <path> is the relative location for the cloned
|
|
submodule to exist in the superproject. If <path> is not given, the
|
|
canonical part of the source repository is used ("repo" for
|
|
"/path/to/repo.git" and "foo" for "host.xz:foo/.git"). If <path>
|
|
exists and is already a valid Git repository, then it is staged
|
|
for commit without cloning. The <path> is also used as the submodule's
|
|
logical name in its configuration entries unless `--name` is used
|
|
to specify a logical name.
|
|
+
|
|
The given URL is recorded into `.gitmodules` 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 `.gitmodules`.
|
|
|
|
status [--cached] [--recursive] [--] [<path>...]::
|
|
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 'git describe' for the
|
|
SHA-1. Each SHA-1 will possibly be prefixed with `-` if the submodule is
|
|
not initialized, `+` if the currently checked out submodule commit
|
|
does not match the SHA-1 found in the index of the containing
|
|
repository and `U` if the submodule has merge conflicts.
|
|
+
|
|
If `--recursive` is specified, this command will recurse into nested
|
|
submodules, and show their status as well.
|
|
+
|
|
If you are only interested in changes of the currently initialized
|
|
submodules with respect to the commit recorded in the index or the HEAD,
|
|
linkgit:git-status[1] and linkgit:git-diff[1] will provide that information
|
|
too (and can also report changes to a submodule's work tree).
|
|
|
|
init [--] [<path>...]::
|
|
Initialize the submodules recorded in the index (which were
|
|
added and committed elsewhere) by setting `submodule.$name.url`
|
|
in .git/config. It uses the same setting from `.gitmodules` as
|
|
a template. If the URL is relative, it will be resolved using
|
|
the default remote. If there is no default remote, the current
|
|
repository will be assumed to be upstream.
|
|
+
|
|
Optional <path> arguments limit which submodules will be initialized.
|
|
If no path is specified and submodule.active has been configured, submodules
|
|
configured to be active will be initialized, otherwise all submodules are
|
|
initialized.
|
|
+
|
|
When present, it will also copy the value of `submodule.$name.update`.
|
|
This command does not alter existing information in .git/config.
|
|
You can then customize the submodule clone URLs in .git/config
|
|
for your local setup and proceed to `git submodule update`;
|
|
you can also just use `git submodule update --init` without
|
|
the explicit 'init' step if you do not intend to customize
|
|
any submodule locations.
|
|
+
|
|
See the add subcommand for the definition of default remote.
|
|
|
|
deinit [-f|--force] (--all|[--] <path>...)::
|
|
Unregister the given submodules, i.e. remove the whole
|
|
`submodule.$name` section from .git/config together with their work
|
|
tree. Further calls to `git submodule update`, `git submodule foreach`
|
|
and `git submodule sync` 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.
|
|
+
|
|
When the command is run without pathspec, it errors out,
|
|
instead of deinit-ing everything, to prevent mistakes.
|
|
+
|
|
If `--force` is specified, the submodule's working tree will
|
|
be removed even if it contains local modifications.
|
|
+
|
|
If you really want to remove a submodule from the repository and commit
|
|
that use linkgit:git-rm[1] instead. See linkgit:gitsubmodules[7] for removal
|
|
options.
|
|
|
|
update [--init] [--remote] [-N|--no-fetch] [--[no-]recommend-shallow] [-f|--force] [--checkout|--rebase|--merge] [--reference <repository>] [--depth <depth>] [--recursive] [--jobs <n>] [--] [<path>...]::
|
|
+
|
|
--
|
|
Update the registered submodules to match what the superproject
|
|
expects by cloning missing submodules and updating the working tree of
|
|
the submodules. The "updating" can be done in several ways depending
|
|
on command line options and the value of `submodule.<name>.update`
|
|
configuration variable. The command line option takes precedence over
|
|
the configuration variable. If neither is given, a 'checkout' is performed.
|
|
The 'update' procedures supported both from the command line as well as
|
|
through the `submodule.<name>.update` configuration are:
|
|
|
|
checkout;; the commit recorded in the superproject will be
|
|
checked out in the submodule on a detached HEAD.
|
|
+
|
|
If `--force` is specified, the submodule will be checked out (using
|
|
`git checkout --force`), even if the commit specified
|
|
in the index of the containing repository already matches the commit
|
|
checked out in the submodule.
|
|
|
|
rebase;; the current branch of the submodule will be rebased
|
|
onto the commit recorded in the superproject.
|
|
|
|
merge;; the commit recorded in the superproject will be merged
|
|
into the current branch in the submodule.
|
|
|
|
The following 'update' procedures are only available via the
|
|
`submodule.<name>.update` configuration variable:
|
|
|
|
custom command;; arbitrary shell command that takes a single
|
|
argument (the sha1 of the commit recorded in the
|
|
superproject) is executed. When `submodule.<name>.update`
|
|
is set to '!command', the remainder after the exclamation mark
|
|
is the custom command.
|
|
|
|
none;; the submodule is not updated.
|
|
|
|
If the submodule is not yet initialized, and you just want to use the
|
|
setting as stored in `.gitmodules`, you can automatically initialize the
|
|
submodule with the `--init` option.
|
|
|
|
If `--recursive` is specified, this command will recurse into the
|
|
registered submodules, and update any nested submodules within.
|
|
--
|
|
summary [--cached|--files] [(-n|--summary-limit) <n>] [commit] [--] [<path>...]::
|
|
Show commit summary between the given commit (defaults to HEAD) and
|
|
working tree/index. For a submodule in question, a series of commits
|
|
in the submodule between the given super project commit and the
|
|
index or working tree (switched by `--cached`) are shown. If the option
|
|
`--files` is given, show the series of commits in the submodule between
|
|
the index of the super project and the working tree of the submodule
|
|
(this option doesn't allow to use the `--cached` option or to provide an
|
|
explicit commit).
|
|
+
|
|
Using the `--submodule=log` option with linkgit:git-diff[1] will provide that
|
|
information too.
|
|
|
|
foreach [--recursive] <command>::
|
|
Evaluates an arbitrary shell command in each checked out submodule.
|
|
The command has access to the variables $name, $path, $sha1 and
|
|
$toplevel:
|
|
$name is the name of the relevant submodule section in `.gitmodules`,
|
|
$path is the name of the submodule directory relative to the
|
|
superproject, $sha1 is the commit as recorded in the superproject,
|
|
and $toplevel is the absolute path to the top-level of the superproject.
|
|
Any submodules defined in the superproject but not checked out are
|
|
ignored by this command. Unless given `--quiet`, foreach prints the name
|
|
of each submodule before evaluating the command.
|
|
If `--recursive` is given, submodules are traversed recursively (i.e.
|
|
the given shell command is evaluated in nested submodules as well).
|
|
A non-zero return from the command in any submodule causes
|
|
the processing to terminate. This can be overridden by adding '|| :'
|
|
to the end of the command.
|
|
+
|
|
As an example, the command below will show the path and currently
|
|
checked out commit for each submodule:
|
|
+
|
|
--------------
|
|
git submodule foreach 'echo $path `git rev-parse HEAD`'
|
|
--------------
|
|
|
|
sync [--recursive] [--] [<path>...]::
|
|
Synchronizes submodules' remote URL configuration setting
|
|
to the value specified in `.gitmodules`. It will only affect those
|
|
submodules which already have a URL entry in .git/config (that is the
|
|
case when they are initialized or freshly added). This is useful when
|
|
submodule URLs change upstream and you need to update your local
|
|
repositories accordingly.
|
|
+
|
|
`git submodule sync` synchronizes all submodules while
|
|
`git submodule sync -- A` synchronizes submodule "A" only.
|
|
+
|
|
If `--recursive` is specified, this command will recurse into the
|
|
registered submodules, and sync any nested submodules within.
|
|
|
|
absorbgitdirs::
|
|
If a git directory of a submodule is inside the submodule,
|
|
move the git directory of the submodule into its superprojects
|
|
`$GIT_DIR/modules` path and then connect the git directory and
|
|
its working directory by setting the `core.worktree` and adding
|
|
a .git file pointing to the git directory embedded in the
|
|
superprojects git directory.
|
|
+
|
|
A repository that was cloned independently and later added as a submodule or
|
|
old setups have the submodules git directory inside the submodule instead of
|
|
embedded into the superprojects git directory.
|
|
+
|
|
This command is recursive by default.
|
|
|
|
OPTIONS
|
|
-------
|
|
-q::
|
|
--quiet::
|
|
Only print error messages.
|
|
|
|
--all::
|
|
This option is only valid for the deinit command. Unregister all
|
|
submodules in the working tree.
|
|
|
|
-b::
|
|
--branch::
|
|
Branch of repository to add as submodule.
|
|
The name of the branch is recorded as `submodule.<name>.branch` in
|
|
`.gitmodules` for `update --remote`. A special value of `.` is used to
|
|
indicate that the name of the branch in the submodule should be the
|
|
same name as the current branch in the current repository.
|
|
|
|
-f::
|
|
--force::
|
|
This option is only valid for add, deinit and update commands.
|
|
When running add, allow adding an otherwise ignored submodule path.
|
|
When running deinit the submodule working trees will be removed even
|
|
if they contain local changes.
|
|
When running update (only effective with the checkout procedure),
|
|
throw away local changes in submodules when switching to a
|
|
different commit; and always run a checkout operation in the
|
|
submodule, even if the commit listed in the index of the
|
|
containing repository matches the commit checked out in the
|
|
submodule.
|
|
|
|
--cached::
|
|
This option is only valid for status and summary commands. These
|
|
commands typically use the commit found in the submodule HEAD, but
|
|
with this option, the commit stored in the index is used instead.
|
|
|
|
--files::
|
|
This option is only valid for the summary command. This command
|
|
compares the commit in the index with that in the submodule HEAD
|
|
when this option is used.
|
|
|
|
-n::
|
|
--summary-limit::
|
|
This option is only valid for the summary command.
|
|
Limit the summary size (number of commits shown in total).
|
|
Giving 0 will disable the summary; a negative number means unlimited
|
|
(the default). This limit only applies to modified submodules. The
|
|
size is always limited to 1 for added/deleted/typechanged submodules.
|
|
|
|
--remote::
|
|
This option is only valid for the update command. Instead of using
|
|
the superproject's recorded SHA-1 to update the submodule, use the
|
|
status of the submodule's remote-tracking branch. The remote used
|
|
is branch's remote (`branch.<name>.remote`), defaulting to `origin`.
|
|
The remote branch used defaults to `master`, but the branch name may
|
|
be overridden by setting the `submodule.<name>.branch` option in
|
|
either `.gitmodules` or `.git/config` (with `.git/config` taking
|
|
precedence).
|
|
+
|
|
This works for any of the supported update procedures (`--checkout`,
|
|
`--rebase`, etc.). The only change is the source of the target SHA-1.
|
|
For example, `submodule update --remote --merge` will merge upstream
|
|
submodule changes into the submodules, while `submodule update
|
|
--merge` will merge superproject gitlink changes into the submodules.
|
|
+
|
|
In order to ensure a current tracking branch state, `update --remote`
|
|
fetches the submodule's remote repository before calculating the
|
|
SHA-1. If you don't want to fetch, you should use `submodule update
|
|
--remote --no-fetch`.
|
|
+
|
|
Use this option to integrate changes from the upstream subproject with
|
|
your submodule's current HEAD. Alternatively, you can run `git pull`
|
|
from the submodule, which is equivalent except for the remote branch
|
|
name: `update --remote` uses the default upstream repository and
|
|
`submodule.<name>.branch`, while `git pull` uses the submodule's
|
|
`branch.<name>.merge`. Prefer `submodule.<name>.branch` if you want
|
|
to distribute the default upstream branch with the superproject and
|
|
`branch.<name>.merge` if you want a more native feel while working in
|
|
the submodule itself.
|
|
|
|
-N::
|
|
--no-fetch::
|
|
This option is only valid for the update command.
|
|
Don't fetch new objects from the remote site.
|
|
|
|
--checkout::
|
|
This option is only valid for the update command.
|
|
Checkout the commit recorded in the superproject on a detached HEAD
|
|
in the submodule. This is the default behavior, the main use of
|
|
this option is to override `submodule.$name.update` when set to
|
|
a value other than `checkout`.
|
|
If the key `submodule.$name.update` is either not explicitly set or
|
|
set to `checkout`, this option is implicit.
|
|
|
|
--merge::
|
|
This option is only valid for the update command.
|
|
Merge the commit recorded in the superproject into the current branch
|
|
of the submodule. If this option is given, the submodule's HEAD will
|
|
not be detached. If a merge failure prevents this process, you will
|
|
have to resolve the resulting conflicts within the submodule with the
|
|
usual conflict resolution tools.
|
|
If the key `submodule.$name.update` is set to `merge`, this option is
|
|
implicit.
|
|
|
|
--rebase::
|
|
This option is only valid for the update command.
|
|
Rebase the current branch onto the commit recorded in the
|
|
superproject. If this option is given, the submodule's HEAD will not
|
|
be detached. If a merge failure prevents this process, you will have
|
|
to resolve these failures with linkgit:git-rebase[1].
|
|
If the key `submodule.$name.update` is set to `rebase`, this option is
|
|
implicit.
|
|
|
|
--init::
|
|
This option is only valid for the update command.
|
|
Initialize all submodules for which "git submodule init" has not been
|
|
called so far before updating.
|
|
|
|
--name::
|
|
This option is only valid for the add command. It sets the submodule's
|
|
name to the given string instead of defaulting to its path. The name
|
|
must be valid as a directory name and may not end with a '/'.
|
|
|
|
--reference <repository>::
|
|
This option is only valid for add and update commands. These
|
|
commands sometimes need to clone a remote repository. In this case,
|
|
this option will be passed to the linkgit:git-clone[1] command.
|
|
+
|
|
*NOTE*: Do *not* use this option unless you have read the note
|
|
for linkgit:git-clone[1]'s `--reference` and `--shared` options carefully.
|
|
|
|
--recursive::
|
|
This option is only valid for foreach, update, status and sync commands.
|
|
Traverse submodules recursively. The operation is performed not
|
|
only in the submodules of the current repo, but also
|
|
in any nested submodules inside those submodules (and so on).
|
|
|
|
--depth::
|
|
This option is valid for add and update commands. Create a 'shallow'
|
|
clone with a history truncated to the specified number of revisions.
|
|
See linkgit:git-clone[1]
|
|
|
|
--[no-]recommend-shallow::
|
|
This option is only valid for the update command.
|
|
The initial clone of a submodule will use the recommended
|
|
`submodule.<name>.shallow` as provided by the `.gitmodules` file
|
|
by default. To ignore the suggestions use `--no-recommend-shallow`.
|
|
|
|
-j <n>::
|
|
--jobs <n>::
|
|
This option is only valid for the update command.
|
|
Clone new submodules in parallel with as many jobs.
|
|
Defaults to the `submodule.fetchJobs` option.
|
|
|
|
<path>...::
|
|
Paths to submodule(s). When specified this will restrict the command
|
|
to only operate on the submodules found at the specified paths.
|
|
(This argument is required with add).
|
|
|
|
FILES
|
|
-----
|
|
When initializing submodules, a `.gitmodules` file in the top-level directory
|
|
of the containing repository is used to find the url of each submodule.
|
|
This file should be formatted in the same way as `$GIT_DIR/config`. The key
|
|
to each submodule url is "submodule.$name.url". See linkgit:gitmodules[5]
|
|
for details.
