#create(name, oid, options = {}) ⇒ Object #create(name, target, options = {}) ⇒ Object

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.

:message

A single line log message to be appended to the reflog.

:signature

The signature to be used for populating the reflog entry.

If a reference with the given name already exists and :force is not true, an exception will be raised.

The :message and :signature options are ignored if the reference does not belong to the standard set (HEAD, refs/heads/*, refs/remotes/* or refs/notes/*) and it does not have a reflog.

#delete(ref) ⇒ nil #delete(name) ⇒ nil

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.

# Reference no longer exists on disk

Overloads:

    Returns:

#each(glob = nil) {|ref| ... } ⇒ nil #each(glob = nil) ⇒ Object

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.

Overloads:

    Yields:

    • (ref)

#rename(old_name, new_name, options = {}) ⇒ Object #rename(ref, new_name, options = {}) ⇒ Object

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.

:message

A single line log message to be appended to the reflog.

:signature

The signature to be used for populating the reflog entry.

If a reference with the given new_name already exists and :force is not true, an exception will be raised.

The :message and :signature options are ignored if the reference does not belong to the standard set (HEAD, refs/heads/*, refs/remotes/* or refs/notes/*) and it does not have a reflog.

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.
