Edit commit messages, authors and timestamps during git-rebase

git-fiddle (1)

git-fiddle is a wrapper around git-rebase(1) that allows editing of commit information straight from the git-rebase editor, such as the author date, author name and commit message. This makes it trivial to edit a whole range of commits, shift them through time or alter ownership.

Usage

Usage is almost identical to that of git-rebase.

$ git fiddle -h
git-fiddle

Edit commit meta information during an *interactive* rebase.

`git-fiddle(1)' is a lightweight wrapper around `git-rebase(1)' that
annotates each commit with it's *author* date, the author name, as well
as the commit message. Changes to any of these will then be applied
using an 'exec' script during the git-rebase sequence.

Usage:
  $SCRIPT [--[no-]-fiddle-messages] [args...]

Options:
  --[no-]fiddle-messages Do not edit commit messages. Useful for quick edits
                         to author or date. This value can also be set using
                         `git config fiddle.messages`.
  [args...]              These arguments are passed verbatim to git-rebase.
