"""interactive history editing
|
|
|
|
|
|
With this extension installed, Mercurial gains one new command: histedit. Usage
|
|
|
is as follows, assuming the following history::
|
|
|
|

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 c561b4e977df and 7c2fd3b9020c
|
|
|
#
|
|
|
# Commits are listed from least to most recent
|
|
|
#
|
|
|
# Commands:
|
|
|
# p, pick = use commit
|
|
|
# e, edit = use commit, but stop for amending
|
|
|
# f, fold = use commit, but combine it with the one above
|
|
|
# r, roll = like fold, but discard this commit's description
|
|
|
# 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 c561b4e977df and 7c2fd3b9020c
|
|
|
#
|
|
|
# Commits are listed from least to most recent
|
|
|
#
|
|
|
# Commands:
|
|
|
# p, pick = use commit
|
|
|
# e, edit = use commit, but stop for amending
|
|
|
# f, fold = use commit, but combine it with the one above
|
|
|
# r, roll = like fold, but discard this commit's description
|
|
|
# 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
|
|
|
|
|
|
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.

|

|
|
|
|
|
|
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 histedit-ed example repository above and add four more
|
|
|
changes, such that we have the following history::

If you run ``hg histedit --outgoing`` on the clone then it is the same

repository that Mercurial does not detect to be related to the source
|
|
|
repo, you can add a ``--force`` option.
