5 | # SHORT DESCRIPTION | |
6 | # | |
7 | # This script makes it easy to fix up commits in the middle of a series, | |
8 | # and rearrange commits. | |
9 | # | |
10 | # The original idea comes from Eric W. Biederman, in | |
11 | # http://article.gmane.org/gmane.comp.version-control.git/22407 | |

13 | # The file containing rebase commands, comments, and empty lines. |
14 | # This file is created by "git rebase -i" then edited by the user. As | |
15 | # the lines are processed, they are removed from the front of this | |
6bb4e485 | 16 | # file and written to the tail of $done. |

28 | # The file into which is accumulated the suggested commit message for | |
29 | # squash/fixup commands. When the first of a series of squash/fixups | |
30 | # is seen, the file is created and the commit message from the | |
31 | # previous commit and from the first squash/fixup commit are written | |
32 | # to it. The commit message for each subsequent squash/fixup commit | |
33 | # is appended to the file as it is processed. | |
34 | # | |
35 | # The first line of the file is of the form | |
6bb4e485 MZ |
36 | # # This is a combination of $count commits. |
37 | # where $count is the number of commits whose messages have been | |
80883bb3 MH |
38 | # written to the file so far (including the initial "pick" commit). |
39 | # Each time that a commit message is processed, this line is read and | |
40 | # updated. It is deleted just before the combined commit is made. | |

44 | # command, then this file exists and holds the commit message of the | |
45 | # original "pick" commit. (If the series ends without a "squash" | |
46 | # command, then this can be used as the commit message of the combined | |
47 | # commit without opening the editor.) | |
