;;; Commentary:
|
|
|
|
;; This package assists the user in editing the list of commits to be
|
|
;; rewritten during an interactive rebase.
|
|
|
|
;; When the user initiates an interactive rebase, e.g. using "r e" in
|
|
;; a Magit buffer or on the command line using "git rebase -i REV",
|
|
;; Git invokes the `$GIT_SEQUENCE_EDITOR' (or if that is undefined
|
|
;; `$GIT_EDITOR' or even `$EDITOR') letting the user rearrange, drop,
|
|
;; reword, edit, and squash commits.
|
|
|
|
;; This package provides the major-mode `git-rebase-mode' which makes
|
|
;; doing so much more fun, by making the buffer more colorful and
|
|
;; providing the following commands:
|
|
;;
|
|
;; C-c C-c Tell Git to make it happen.
|
|
;; C-c C-k Tell Git that you changed your mind, i.e. abort.
|
|
;;
|
|
;; p Move point to previous line.
|
|
;; n Move point to next line.
|
|
;;
|
|
;; M-p Move the commit at point up.
|
|
;; M-n Move the commit at point down.
|
|
;;
|
|
;; k Drop the commit at point.
|
|
;; c Don't drop the commit at point.
|
|
;; r Change the message of the commit at point.
|
|
;; e Edit the commit at point.
|
|
;; s Squash the commit at point, into the one above.
|
|
;; f Like "s" but don't also edit the commit message.
|
|
;; b Break for editing at this point in the sequence.
|
|
;; x Add a script to be run with the commit at point
|
|
;; being checked out.
|
|
;; z Add noop action at point.
|
|
;;
|
|
;; SPC Show the commit at point in another buffer.
|
|
;; RET Show the commit at point in another buffer and
|
|
;; select its window.
|
|
;; C-/ Undo last change.
|
|
;;
|
|
;; Commands for --rebase-merges:
|
|
;; l Associate label with current HEAD in sequence.
|
|
;; MM Merge specified revisions into HEAD.
|
|
;; Mt Toggle whether the merge will invoke an editor
|
|
;; before committing.
|
|
;; t Reset HEAD to the specified label.
|
|
|
|
;; You should probably also read the `git-rebase' manpage.
