var result = submodule.addToIndex(write_index);

| Parameters | Type | | --- | --- | --- | | write_index | Number | Boolean if this should immediately write the index file. If you pass this as false, you will have to get the git_index and explicitly call git_index_write() on it to save the change. |

var string = submodule.branch();

submodule.free();

var oid = submodule.headId();

var result = submodule.ignore();

     this submodule. |

var oid = submodule.indexId();

var result = submodule.init(overwrite);

| Parameters | Type | | --- | --- | --- | | overwrite | Number | By default, existing entries will not be overwritten, but setting this to true forces them to be updated. |

var string = submodule.name();

var result = submodule.open(repo);

| Parameters | Type | | --- | --- | --- | | repo | Repository | Pointer to the submodule repo which was opened |

var repository = submodule.owner();

var string = submodule.path();

var result = submodule.reload(force);

| Parameters | Type | | --- | --- | --- | | force | Number | Force reload even if the data doesn't seem out of date |

submodule.repoInit(use_gitlink).then(function(repository) {
  // Use repository
});

| Parameters | Type | | --- | --- | --- | | use_gitlink | Number | Should the workdir contain a gitlink to the repo in .git/modules vs. repo directly in workdir. |

var result = submodule.sync();

var result = submodule.update(init, options);

| Parameters | Type | | --- | --- | --- | | init | Number | If the submodule is not initialized, setting this flag to true will initialize the submodule before updating. Otherwise, this will return an error if attempting to update an uninitialzed repository. but setting this to true forces them to be updated. | | options | SubmoduleUpdateOptions | configuration options for the update. If NULL, the function works as though GIT_SUBMODULE_UPDATE_OPTIONS_INIT was passed. |

     function, or a negative value to indicate an error (use
     `giterr_last` for a detailed error message). |

var result = submodule.updateStrategy();

     for this submodule. |
