Class Method Details

.new(repo, branch, upstream[, onto][, options]) ⇒ Object

Initialize a new rebase operation. This will put repo in a rebase state.

branch is the branch to be rebased, and upstream is the branch which is to be the new base. If onto is specified, this will be the one base, and upstream is used to determine which commits from branch to use for the rebase.

You can pass merge and checkout options for the options hash, plus a few rebase-specific ones:

:quiet

If true, a flag will be set to ask tools to activate quiet mode. This does not do anything for libgit2/rugged but can be used to interact with other implementations.

:inmemory

Do not put the repository in a rebase state but perform all the operations in-memory. In case of conflicts, the rebase operation Hash returned by #next will contain the index which can be used to resolve conflicts.

:rewrite_notes_ref

Name of the notes reference used to rewrite notes for rebased commits when finishing the rebase. If nil, it will be taken from the configuration.

#commit(author: nil, committer: committer, message: nil) ⇒ nil

Commit the current patch. Any conflicts must have been resolved.

If author is nil, the existing author for the commit will be used. If message is nil, the existing message will be used.

Returns a string containing the oid of the newly created commit, or nil if there are no changes to be committed.

Returns:

  • (nil)

#inmemory_indexObject

Gets the index produced by the last operation, which is the result of next and which will be committed by the next invocation of commit. This is useful for resolving conflicts in an in-memory rebase before committing them.

This is only applicable for in-memory rebases; for rebases within a working directory, the changes were applied to the repository’s index.

	return rugged_index_new(rb_cRuggedIndex, self, index);
}

#nextnil

Perform the next step in the rebase. The returned operation is a Hash with its details or nil if there are no more operations to perform. The Hash contains some of the following entries:

:type

The type of operation being done. Can be one of :pick, :reword, :edit, :squash, :fixup or :exec.

:id

The id of the commit being cherry-picked. Exists for all but :exec operations.

:exec

If the operatin is :exec this is what the user asked to be executed.

Returns:

  • (nil)
