-gitmodules - defining submodule properties
+gitmodules - Defining submodule properties
SYNOPSIS
--------
The file contains one subsection per submodule, and the subsection value
is the name of the submodule. The name is set to the path where the
-submodule has been added unless it was customized with the '--name'
+submodule has been added unless it was customized with the `--name`
option of 'git submodule add'. Each submodule section also contains the
following required keys:
linkgit:git-clone[1] or (if it begins with ./ or ../) a location
relative to the superproject's origin repository.
+In addition, there are a number of optional keys:
+
submodule.<name>.update::
- Defines what to do when the submodule is updated by the superproject.
- If 'checkout' (the default), the new commit specified in the
- superproject will be checked out in the submodule on a detached HEAD.
- If 'rebase', the current branch of the submodule will be rebased onto
- the commit specified in the superproject. If 'merge', the commit
- specified in the superproject will be merged into the current branch
- in the submodule.
- If 'none', the submodule with name `$name` will not be updated
- by default.
-
- This config option is overridden if 'git submodule update' is given
- the '--merge', '--rebase' or '--checkout' options.
+ Defines the default update procedure for the named submodule,
+ i.e. how the submodule is updated by "git submodule update"
+ command in the superproject. This is only used by `git
+ submodule init` to initialize the configuration variable of
+ the same name. Allowed values here are 'checkout', 'rebase',
+ 'merge' or 'none'. See description of 'update' command in
+ linkgit:git-submodule[1] for their meaning. Note that the
+ '!command' form is intentionally ignored here for security
+ reasons.
submodule.<name>.branch::
A remote branch name for tracking updates in the upstream submodule.
- If the option is not specified, it defaults to 'master'. See the
- `--remote` documentation in linkgit:git-submodule[1] for details.
+ If the option is not specified, it defaults to 'master'. 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. See the `--remote` documentation in
+ linkgit:git-submodule[1] for details.
submodule.<name>.fetchRecurseSubmodules::
This option can be used to control recursive fetching of this
submodule.<name>.ignore::
Defines under what circumstances "git status" and the diff family show
- a submodule as modified. When set to "all", it will never be considered
- modified, "dirty" will ignore all changes to the submodules work tree and
- takes only differences between the HEAD of the submodule and the commit
- recorded in the superproject into account. "untracked" will additionally
- let submodules with modified tracked files in their work tree show up.
- Using "none" (the default when this option is not set) also shows
- submodules that have untracked files in their work tree as changed.
- If this option is also present in the submodules entry in .git/config of
- the superproject, the setting there will override the one found in
+ a submodule as modified. The following values are supported:
+
+ all;; The submodule will never be considered modified (but will
+ nonetheless show up in the output of status and commit when it has
+ been staged).
+
+ dirty;; All changes to the submodule's work tree will be ignored, only
+ committed differences between the HEAD of the submodule and its
+ recorded state in the superproject are taken into account.
+
+ untracked;; Only untracked files in submodules will be ignored.
+ Committed differences and modifications to tracked files will show
+ up.
+
+ none;; No modifiations to submodules are ignored, all of committed
+ differences, and modifications to tracked and untracked files are
+ shown. This is the default option.
+
+ If this option is also present in the submodules entry in .git/config
+ of the superproject, the setting there will override the one found in
.gitmodules.
Both settings can be overridden on the command line by using the
- "--ignore-submodule" option.
+ "--ignore-submodule" option. The 'git submodule' commands are not
+ affected by this setting.
+
+submodule.<name>.shallow::
+ When set to true, a clone of this submodule will be performed as a
+ shallow clone (with a history depth of 1) unless the user explicitly
+ asks for a non-shallow clone.
