## Functions

### GgitSubmoduleCallback ()

    gint
    (*GgitSubmoduleCallback) (GgitSubmodule *submodule,
                              const gchar *name,
                              gpointer user_data);

The type of the callback functions for retrieving the submodules in a GgitRepository. See `ggit_repository_submodule_foreach()`.

#### Parameters

submodule | a GgitSubmodule. |
name | the name of the submodule. |
user_data | user-supplied data. | [closure]

#### Returns

0 to go for the next submodule or a GgitError in case there was an error.

### ggit_submodule_ref ()

    GgitSubmodule *
    ggit_submodule_ref (GgitSubmodule *submodule);

Atomically increments the reference count of `submodule` by one. This function is MT-safe and may be called from any thread.

#### Parameters

submodule | a GgitSubmodule. |

#### Returns

the passed in GgitSubmodule or `NULL`.

[transfer none][nullable]

### ggit_submodule_unref ()

    void
    ggit_submodule_unref (GgitSubmodule *submodule);

Atomically decrements the reference count of `submodule` by one. If the reference count drops to 0, `remote` is freed.

#### Parameters

submodule | a GgitSubmodule. |

### ggit_submodule_get_owner ()

    GgitRepository *
    ggit_submodule_get_owner (GgitSubmodule *submodule);

Gets the containing repository for a submodule.

#### Parameters

submodule | a GgitSubmodule. |

#### Returns

the containing repository for a submodule or `NULL`.

[transfer full][nullable]

### ggit_submodule_get_name ()

    const gchar *
    ggit_submodule_get_name (GgitSubmodule *submodule);

Gets the name of the submodule from .gitmodules.

#### Parameters

submodule | a GgitSubmodule. |

#### Returns

the name of the submodule from .gitmodules or `NULL`.

[transfer none][nullable]

### ggit_submodule_get_path ()

    const gchar *
    ggit_submodule_get_path (GgitSubmodule *submodule);

Gets the path to the submodule from the repo working directory. It is almost always the same as the name. See `ggit_submodule_get_name()`.

#### Parameters

submodule | a GgitSubmodule. |

#### Returns

the path to the submodule from the repo working directory or `NULL`.

[transfer none][nullable]

### ggit_submodule_get_url ()

    const gchar *
    ggit_submodule_get_url (GgitSubmodule *submodule);

Gets the url for the submodule or `NULL` if the submodule has been deleted but not yet committed.

#### Parameters

submodule | a GgitSubmodule. |

#### Returns

the url for the submodule or `NULL`.

[transfer none][nullable]

### ggit_submodule_get_index_id ()

    GgitOId *
    ggit_submodule_get_index_id (GgitSubmodule *submodule);

Gets the OID for the submodule in the index or `NULL` if there is no index.

#### Parameters

submodule | a GgitSubmodule. |

#### Returns

the OID for the submodule in the index or `NULL`.

[transfer full][nullable]

### ggit_submodule_get_head_id ()

    GgitOId *
    ggit_submodule_get_head_id (GgitSubmodule *submodule);

### ggit_submodule_get_workdir_id ()

    GgitOId *
    ggit_submodule_get_workdir_id (GgitSubmodule *submodule);

Gets the OID for the submodule in the current working directory. Corresponds to looking up 'HEAD' in the checked out submodule. If there are pending changes in the index or anything else, this won't notice that. You should call `ggit_submodule_status()` for a more complete picture about the state of the working directory.

#### Parameters

submodule | a GgitSubmodule. |

#### Returns

the OID for the submodule in the current working directory or `NULL`.

[transfer full][nullable]

### ggit_submodule_get_ignore ()

    GgitSubmoduleIgnore
    ggit_submodule_get_ignore (GgitSubmodule *submodule);

Gets a GgitSubmoduleIgnore. See see gitmodules(5) ignore.

#### Parameters

submodule | a GgitSubmodule. |

#### Returns

the GgitSubmoduleIgnore.

### ggit_submodule_get_update ()

    GgitSubmoduleUpdate
    ggit_submodule_get_update (GgitSubmodule *submodule);

Gets a GgitSubmoduleUpdate. See see gitmodules(5) update.

#### Parameters

submodule | a GgitSubmodule. |

#### Returns

the GgitSubmoduleUpdate.

### ggit_submodule_get_fetch_recurse ()

    gboolean
    ggit_submodule_get_fetch_recurse (GgitSubmodule *submodule);

Gets whether to fetch recursively. See see gitmodules(5) fetchRecurseSubmodules.

#### Parameters

submodule | a GgitSubmodule. |

#### Returns

whether or not fetch recursively.

### ggit_submodule_init ()

    void
    ggit_submodule_init (GgitSubmodule *submodule,
                         gboolean overwrite,
                         GError **error);

Just like "git submodule init", this copies information about the submodule into ".git/config". You can use the accessor functions above to alter the in-memory git_submodule object and control what is written to the config, overriding what is in .gitmodules.

#### Parameters

submodule | a GgitSubmodule. |
overwrite | forces existing entries to be updated. |
error | a GError for error reporting, or `NULL`. |

### ggit_submodule_sync ()

    void
    ggit_submodule_sync (GgitSubmodule *submodule,
                         GError **error);

Copies the information about the submodules URL into the checked out submodule config, acting like "git submodule sync". This is useful if you have altered the URL for the submodule (or it has been altered by a fetch of upstream changes) and you need to update your local repo.

#### Parameters

submodule | a GgitSubmodule. |
error | a GError for error reporting, or `NULL`. |

### ggit_submodule_reload ()

    void
    ggit_submodule_reload (GgitSubmodule *submodule,
                           gboolean force,
                           GError **error);

Rereads submodule info from config, index, and HEAD. Call this if you have reason to believe that it has changed.

#### Parameters

submodule | a GgitSubmodule. |
force | reload even if the data doesn't seem out of date. |
error | a GError for error reporting, or `NULL`. |
