Author: Alexis S. L. Carvalho
1. Overview
This extension allows you to use git-style suffixes to refer to the ancestors of a specific revision.
For example, if you can refer to a revision as foo, then:
1. foo^N = Nth parent of foo:
foo^0 = foo
foo^1 = first parent of foo
foo^2 = second parent of foo
foo^ = foo^1
2. foo~N = Nth first grandparent of foo
foo~0 = foo
foo~1 = foo^1 = foo^ = first parent of foo
foo~2 = foo^1^1 = foo^^ = first parent of first parent of foo
So hg log -r tip^^ or hg log -r tip~2 will display the grandparent of tip.
2. Configuration
Configure your .hgrc to enable the extension by adding the following lines:
