|
9 | 9 | With this extension installed, Mercurial gains one new command: histedit. Usage |
|
10 | 10 | is as follows, assuming the following history:: |
|
11 | 11 | |

|
24 | 24 | If you were to run ``hg histedit c561b4e977df``, you would see the following |
|
25 | 25 | file open in your editor:: |
|
26 | 26 | |
|
27 | 27 | pick c561b4e977df Add beta |
|
28 | 28 | pick 030b686bedc4 Add gamma |
|
29 | 29 | pick 7c2fd3b9020c Add delta |
|
30 | 30 | |
|
31 | 31 | # Edit history between 633536316234 and 7c2fd3b9020c |
|
32 | 32 | # |
|
33 | 33 | # Commands: |
|
34 | 34 | # p, pick = use commit |
|
35 | 35 | # e, edit = use commit, but stop for amending |
|
36 | 36 | # f, fold = use commit, but fold into previous commit (combines N and N-1) |
|
37 | 37 | # d, drop = remove commit from history |
|
38 | 38 | # m, mess = edit message without changing commit content |
|
39 | 39 | # |
|
40 | 40 | |
|
41 | 41 | In this file, lines beginning with ``#`` are ignored. You must specify a rule |
|
42 | 42 | for each revision in your history. For example, if you had meant to add gamma |
|
43 | 43 | before beta, and then wanted to add delta in the same revision as beta, you |
|
44 | 44 | would reorganize the file to look like this:: |
|
45 | 45 | |
|
46 | 46 | pick 030b686bedc4 Add gamma |
|
47 | 47 | pick c561b4e977df Add beta |
|
48 | 48 | fold 7c2fd3b9020c Add delta |
|
49 | 49 | |
|
50 | 50 | # Edit history between 633536316234 and 7c2fd3b9020c |
|
51 | 51 | # |
|
52 | 52 | # Commands: |
|
53 | 53 | # p, pick = use commit |
|
54 | 54 | # e, edit = use commit, but stop for amending |
|
55 | 55 | # f, fold = use commit, but fold into previous commit (combines N and N-1) |
|
56 | 56 | # d, drop = remove commit from history |
|
57 | 57 | # m, mess = edit message without changing commit content |
|
58 | 58 | # |
|
59 | 59 | |
|
60 | 60 | At which point you close the editor and ``histedit`` starts working. When you |
|
61 | 61 | specify a ``fold`` operation, ``histedit`` will open an editor when it folds |
|
62 | 62 | those revisions together, offering you a chance to clean up the commit message:: |
|
63 | 63 | |
|
64 | 64 | Add beta |
|
65 | 65 | *** |
|
66 | 66 | Add delta |
|
67 | 67 | |
|
68 | 68 | Edit the commit message to your liking, then close the editor. For |
|
69 | 69 | this example, let's assume that the commit message was changed to |
|
70 | 70 | ``Add beta and delta.`` After histedit has run and had a chance to |
|
71 | 71 | remove any old or temporary revisions it needed, the history looks |
|
72 | 72 | like this:: |
|
73 | 73 | |
|
74 | 74 | @ 2[tip] 989b4d060121 2009-04-27 18:04 -0500 durin42 |
|
75 | 75 | | Add beta and delta. |
|
76 | 76 | | |
|
77 | 77 | o 1 081603921c3f 2009-04-27 18:04 -0500 durin42 |
|
78 | 78 | | Add gamma |

|
81 | 81 | Add alpha |
|
82 | 82 | |
|
83 | 83 | Note that ``histedit`` does *not* remove any revisions (even its own temporary |
|
84 | 84 | ones) until after it has completed all the editing operations, so it will |
|
85 | 85 | probably perform several strip operations when it's done. For the above example, |
|
86 | 86 | it had to run strip twice. Strip can be slow depending on a variety of factors, |
|
87 | 87 | so you might need to be a little patient. You can choose to keep the original |
|
88 | 88 | revisions by passing the ``--keep`` flag. |
|
89 | 89 | |
|
90 | 90 | The ``edit`` operation will drop you back to a command prompt, |
|
91 | 91 | allowing you to edit files freely, or even use ``hg record`` to commit |
|
92 | 92 | some changes as a separate commit. When you're done, any remaining |
|
93 | 93 | uncommitted changes will be committed as well. When done, run ``hg |
|
94 | 94 | histedit --continue`` to finish this step. You'll be prompted for a |
|
95 | 95 | new commit message, but the default commit message will be the |
|
96 | 96 | original message for the ``edit`` ed revision. |
|
97 | 97 | |
|
98 | 98 | The ``message`` operation will give you a chance to revise a commit |
|
99 | 99 | message without changing the contents. It's a shortcut for doing |
|
100 | 100 | ``edit`` immediately followed by `hg histedit --continue``. |
|
101 | 101 | |
|
102 | 102 | If ``histedit`` encounters a conflict when moving a revision (while |
|
103 | 103 | handling ``pick`` or ``fold``), it'll stop in a similar manner to |
|
104 | 104 | ``edit`` with the difference that it won't prompt you for a commit |
|
105 | 105 | message when done. If you decide at this point that you don't like how |
|
106 | 106 | much work it will be to rearrange history, or that you made a mistake, |
|
107 | 107 | you can use ``hg histedit --abort`` to abandon the new changes you |
|
108 | 108 | have made and return to the state before you attempted to edit your |
|
109 | 109 | history. |
|

|
112 | 112 | we have the following history:: |

|
138 | 138 | repo, you can add a ``--force`` option. |
