1 | 1 | To merge files Mercurial uses merge tools. |
|
2 | 2 | |
|
3 | 3 | A merge tool combines two different versions of a file into a merged |
|
4 | 4 | file. Merge tools are given the two files and the greatest common |
|
5 | 5 | ancestor of the two file versions, so they can determine the changes |
|
6 | 6 | made on both branches. |
|
7 | 7 | |
|
8 | 8 | The merge tools are used both for :hg:`resolve` and :hg:`merge`. |
|
9 | 9 | |
|
10 |
Usually, the merge tool tries to automatically |
|
|
11 |
non-overlapping changes that occurred separately in |
|
|
10 | Usually, the merge tool tries to automatically reconcile the files by | |
|
11 | combining all the non-overlapping changes that occurred separately in | |
|
12 | the two different | |
|
12 | 13 | evolutions of the same initial base file. Furthermore, some |
|
13 | 14 | interactive merge programs make it easier to manually resolve |
|
14 | 15 | conflicting merges, either in a graphical way, or by inserting some |
|
15 | 16 | conflict markers. Mercurial does not include any interactive merge |
|
16 | 17 | programs but relies on external tools for that. External merge tools |
|
17 | 18 | and their properties and usage is configured in merge-tools section - |
|
18 | 19 | see hgrc(5). |
|
19 | 20 | |
|
20 | 21 | There are a some internal merge tools which can be used. The internal |
|
21 | 22 | merge tools are: |
|
22 | 23 | |
|
23 | 24 | ``internal:merge`` |
|
24 | 25 | Uses the internal non-interactive merge tool for merging files. |
|
25 | 26 | |
|
26 | 27 | ``internal:fail`` |
|
27 | 28 | Rather than attempting to merge files that were modified on both |
|
28 | 29 | branches, it marks these files as unresolved. Then the resolve |
|
29 | 30 | command must be used to mark files resolved. |
|
30 | 31 | |
|
31 | 32 | ``internal:local`` |
|
32 | 33 | Uses the local version of files as the merged version. |
|
33 | 34 | |
|
34 | 35 | ``internal:other`` |
|
35 | 36 | Uses the remote version of files as the merged version. |
|
36 | 37 | |
|
37 | 38 | ``internal:prompt`` |
|
38 | 39 | Asks the user which of the local or the other version to keep as |
|
39 | 40 | the merged version. |
|
40 | 41 | |
|
41 | 42 | ``internal:dump`` |
|
42 | 43 | Creates three versions of the files to merge, containing the |
|
43 | 44 | contents of local, other and base. These files can then be used to |
|
44 |
perform a merge manually. If the file merged is name |
|
|
45 | these files will accordingly be named ``a.txt.local``, | |
|
45 | perform a merge manually. If the file to be merged is named | |
|
46 | ``a.txt``, these files will accordingly be named ``a.txt.local``, | |
|
46 | 47 | ``a.txt.other`` and ``a.txt.base`` and they will be placed in the |
|
47 |
same directory as |
|
|
48 | same directory as ``a.txt``. | |
|
48 | 49 | |
|
49 | 50 | How Mercurial decides which merge program to use |
|
50 | 51 | |
|
51 | 52 | 1. If the ``HGMERGE`` environment variable is present, it is used. If |
|
52 | 53 | specified it must be either an executable path or the name of an |
|
53 | 54 | application in your executable search path. |
|
54 | 55 | |
|
55 | 56 | 2. If the filename of the file to be merged matches any of the |
|
56 | 57 | patterns in the merge-patterns configuration section, then the |
|
57 | 58 | corresponding merge tool is used, unless the file to be merged is a |
|
58 | 59 | symlink. Here binary capabilities of the merge tool are not |
|
59 | 60 | considered. |
|
60 | 61 | |
|
61 | 62 | 3. If ui.merge is set, it is used. |
|
62 | 63 | |
|
63 | 64 | 4. If any merge tools are present in the merge-tools configuration |
|
64 | 65 | section, and any of the tools can be found on the system, the |
|
65 | 66 | priority settings are used to determine which one to use. Binary, |
|
66 | 67 | symlink and GUI capabilities do also have to match. |
|
67 | 68 | |
|
68 | 69 | 5. If a program named ``hgmerge`` exists on the system, it is used. |
|
69 | 70 | |
|
70 | 71 | 6. If the file to be merged is not binary and is not a symlink, then |
|
71 | 72 | ``internal:merge`` is used. |
|
72 | 73 | |
|
73 | 74 | 7. The merge fails. |
|
74 | 75 | |
|
75 | 76 | .. note:: |
|
76 | 77 | After selecting a merge program, Mercurial will by default attempt |
|
77 | 78 | to merge the files using a simple merge algorithm first, to see if |
|
78 | 79 | they can be merged without conflicts. Only if there are conflicting |
|
79 | 80 | changes Mercurial will actually execute the merge program. Whether |
|
80 |
to use the simple merge algorithm first can be controlled b |
|
|
81 |
premerge setting of the merge tool |
|
|
81 | to use the simple merge algorithm first can be controlled by the | |
|
82 | premerge setting of the merge tool. Premerge is enabled by default | |
|
82 | 83 | unless the file is binary or symlink. |
|
83 | 84 | |
|
84 | 85 | See the merge-tools and ui sections of hgrc(5) for details on |
|
85 | 86 | configuration of merge tools. |
