r17131 | """interactive history editing | ||
With this extension installed, Mercurial gains one new command: histedit. Usage | ||||
is as follows, assuming the following history:: | ||||
@ 3[tip] 7c2fd3b9020c 2009-04-27 18:04 -0500 durin42 | ||||
| Add delta | ||||
| | ||||
o 2 030b686bedc4 2009-04-27 18:04 -0500 durin42 | ||||
| Add gamma | ||||
| | ||||
o 1 c561b4e977df 2009-04-27 18:04 -0500 durin42 | ||||
| Add beta | ||||
| | ||||
o 0 d8d2fcd0e319 2009-04-27 18:04 -0500 durin42 | ||||
Add alpha | ||||
If you were to run ``hg histedit c561b4e977df``, you would see the following | ||||
file open in your editor:: | ||||
pick c561b4e977df Add beta | ||||
pick 030b686bedc4 Add gamma | ||||
pick 7c2fd3b9020c Add delta | ||||
# Edit history between 633536316234 and 7c2fd3b9020c | ||||
# | ||||
# Commands: | ||||
# p, pick = use commit | ||||
# e, edit = use commit, but stop for amending | ||||
|
r17335 | # f, fold = use commit, but fold into previous commit (combines N and N-1) | ||
|
r17131 | # d, drop = remove commit from history | ||
# m, mess = edit message without changing commit content | ||||
# | ||||
In this file, lines beginning with ``#`` are ignored. You must specify a rule | ||||
for each revision in your history. For example, if you had meant to add gamma | ||||
before beta, and then wanted to add delta in the same revision as beta, you | ||||
would reorganize the file to look like this:: | ||||
pick 030b686bedc4 Add gamma | ||||
pick c561b4e977df Add beta | ||||
fold 7c2fd3b9020c Add delta | ||||
# Edit history between 633536316234 and 7c2fd3b9020c | ||||
# | ||||
# Commands: | ||||
# p, pick = use commit | ||||
# e, edit = use commit, but stop for amending | ||||
|
r17335 | # f, fold = use commit, but fold into previous commit (combines N and N-1) | ||
|
r17131 | # d, drop = remove commit from history | ||
# m, mess = edit message without changing commit content | ||||
# | ||||
At which point you close the editor and ``histedit`` starts working. When you | ||||
specify a ``fold`` operation, ``histedit`` will open an editor when it folds | ||||
those revisions together, offering you a chance to clean up the commit message:: | ||||
Add beta | ||||
*** | ||||
Add delta | ||||
|
r17064 | |||
|
r17131 | Edit the commit message to your liking, then close the editor. For | ||
this example, let's assume that the commit message was changed to | ||||
``Add beta and delta.`` After histedit has run and had a chance to | ||||
remove any old or temporary revisions it needed, the history looks | ||||
like this:: | ||||
@ 2[tip] 989b4d060121 2009-04-27 18:04 -0500 durin42 | ||||
| Add beta and delta. | ||||
| | ||||
o 1 081603921c3f 2009-04-27 18:04 -0500 durin42 | ||||
| Add gamma | ||||
| | ||||
o 0 d8d2fcd0e319 2009-04-27 18:04 -0500 durin42 | ||||
Add alpha | ||||
Note that ``histedit`` does *not* remove any revisions (even its own temporary | ||||
ones) until after it has completed all the editing operations, so it will | ||||
probably perform several strip operations when it's done. For the above example, | ||||
it had to run strip twice. Strip can be slow depending on a variety of factors, | ||||
so you might need to be a little patient. You can choose to keep the original | ||||
revisions by passing the ``--keep`` flag. | ||||
The ``edit`` operation will drop you back to a command prompt, | ||||
allowing you to edit files freely, or even use ``hg record`` to commit | ||||
some changes as a separate commit. When you're done, any remaining | ||||
uncommitted changes will be committed as well. When done, run ``hg | ||||
histedit --continue`` to finish this step. You'll be prompted for a | ||||
new commit message, but the default commit message will be the | ||||
original message for the ``edit`` ed revision. | ||||
The ``message`` operation will give you a chance to revise a commit | ||||
message without changing the contents. It's a shortcut for doing | ||||
``edit`` immediately followed by `hg histedit --continue``. | ||||
If ``histedit`` encounters a conflict when moving a revision (while | ||||
handling ``pick`` or ``fold``), it'll stop in a similar manner to | ||||
``edit`` with the difference that it won't prompt you for a commit | ||||
message when done. If you decide at this point that you don't like how | ||||
much work it will be to rearrange history, or that you made a mistake, | ||||
you can use ``hg histedit --abort`` to abandon the new changes you | ||||
have made and return to the state before you attempted to edit your | ||||
history. | ||||
If we clone the example repository above and add three more changes, such that | ||||
we have the following history:: | ||||
@ 6[tip] 038383181893 2009-04-27 18:04 -0500 stefan | ||||
| Add theta | ||||
| | ||||
o 5 140988835471 2009-04-27 18:04 -0500 stefan | ||||
| Add eta | ||||
| | ||||
o 4 122930637314 2009-04-27 18:04 -0500 stefan | ||||
| Add zeta | ||||
| | ||||
o 3 836302820282 2009-04-27 18:04 -0500 stefan | ||||
| Add epsilon | ||||
| | ||||
o 2 989b4d060121 2009-04-27 18:04 -0500 durin42 | ||||
| Add beta and delta. | ||||
| | ||||
o 1 081603921c3f 2009-04-27 18:04 -0500 durin42 | ||||
| Add gamma | ||||
| | ||||
o 0 d8d2fcd0e319 2009-04-27 18:04 -0500 durin42 | ||||
Add alpha | ||||
If you run ``hg histedit --outgoing`` on the clone then it is the same | ||||
as running ``hg histedit 836302820282``. If you need plan to push to a | ||||
repository that Mercurial does not detect to be related to the source | ||||
repo, you can add a ``--force`` option. | ||||
