stack: allow to refer to changeset using "t2" form
hg up "t0" is seen as "update to the first changeset of my current topic".
Eventually we'll drop the "t2" form in favor of the planned generic indexing
operator '.{t2}'.
# topics
Topics are an experiment to see if maybe the workflow defined by git
branches and hg bookmarks is only partially what users want - perhaps
something that feels more like a traditional VCS branch is right, but
that it should "dissolve" upon being finished. This extension exists
to be a sandbox for that experimentation.
# usage
Enable topics like any mercurial extension: download the source code to a
local directory, and add that directory to your `.hgrc`:
[extensions]
topics=path/to/hg-topics/src
If you are using Mercurial 3.7 use:
[extensions]
hgext3rd.topics=path/to/hg-topics/src
