Operating System

POSIX

A Python implementation of 3-way merge of texts.

Given BASE, OTHER, THIS, tries to produce a combined text incorporating the changes from both BASE->OTHER and BASE->THIS. All three will typically be sequences of lines.

Usage

From the command-line:

$ echo foo > mine
$ echo bar > base
$ echo blah > other
$ python -m merge3 mine base other > merged
$ cat merged

Or from Python:

>>> import merge3
>>> m3 = merge3.Merge3(
...                    ['common\n', 'base\n'],
...                    ['common\n', 'a\n'],
...                    ['common\n', 'b\n'])
>>> list(m3.merge_annotated())
['u | common\n', '<<<<\n', 'A | a\n', '----\n', 'B | b\n', '>>>>\n']
