.
static VALUE rb_git_reference_collection_initialize(VALUE self, VALUE repo) { rugged_set_owner(self, repo); return self; }
Public Instance Methods
Lookup a reference in the collection with the given name
.
Returns a new Rugged::Reference
object.
static VALUE rb_git_reference_collection_aref(VALUE self, VALUE rb_name) { VALUE rb_repo = rugged_owner(self); git_repository *repo; git_reference *ref; int error; Data_Get_Struct(rb_repo, git_repository, repo); error = git_reference_lookup(&ref, repo, StringValueCStr(rb_name)); if (error == GIT_ENOTFOUND) return Qnil; rugged_exception_check(error); return rugged_ref_new(rb_cRuggedReference, rb_repo, ref); }
Create a symbolic or direct reference on the collection's repository
with the given name
.
If the second argument is a valid OID, the reference will be created as direct. Otherwise, it will be assumed the target is the name of another reference.
The following options can be passed in the options
Hash:
- :force
-
Overwrites the reference with the given
name
, if it already exists, instead of raising an exception.
If a reference with the given name
already exists and :force
is not true
, an exception will be raised.

Delete specified reference.
If a Rugged::Reference
object was passed, the object will become invalidated and won't be able to be used for any other operations.

Iterate through all the references in the collection's repository
. Iteration can be optionally filtered to the ones matching the given glob
, a standard Unix filename glob.
The given block will be called once with a Rugged::Reference
instance for each reference.
If no block is given, an enumerator will be returned.
static VALUE rb_git_reference_collection_each(int argc, VALUE *argv, VALUE self) { return rb_git_reference_collection__each(argc, argv, self, 0); }
Iterate through all the reference names in the collection's repository
. Iteration can be optionally filtered to the ones matching the given glob
, a standard Unix filename glob.
The given block will be called once with the name of each reference.
If no block is given, an enumerator will be returned.
static VALUE rb_git_reference_collection_each_name(int argc, VALUE *argv, VALUE self) { return rb_git_reference_collection__each(argc, argv, self, 1); }
Check if a given reference exists with the given name
.

Check if a given reference exists with the given name
.
Change the name of a reference. If force
is true
, any previously existing references will be overwritten when renaming.
Return a new reference object with the new object
reference.name #=> 'refs/heads/master' new_ref = references.rename(ref, 'refs/heads/development') #=> <Reference> new_ref.name #=> 'refs/heads/development'
The following options can be passed in the options
Hash:
- :force
-
Overwrites the reference with the given
name
, if it already exists, instead of raising an exception.
If a reference with the given new_name
already exists and :force
is not true
, an exception will be raised.

Change the name of a reference. If force
is true
, any previously existing references will be overwritten when renaming.
Return a new reference object with the new object
reference.name #=> 'refs/heads/master' new_ref = references.rename(ref, 'refs/heads/development') #=> <Reference> new_ref.name #=> 'refs/heads/development'
The following options can be passed in the options
Hash:
- :force
-
Overwrites the reference with the given
name
, if it already exists, instead of raising an exception.
If a reference with the given new_name
already exists and :force
is not true
, an exception will be raised.
Set the target of a reference. If ref
is a direct reference, the new target must be a String
representing a SHA1 OID.
If reference
is symbolic, the new target must be a String
with the name of another reference.
The original reference is unaltered; a new reference object is returned with the new target, and the changes are persisted to disk.
