Mutable History For Mercurial

This package supplies the evolve extension for Mercurial, which provides several commands to mutate history and deal with the resulting issues.

It also:

  • enables the "changeset obsolescence" feature of Mercurial
  • issues several warning messages when trouble appears in your repository

This extension is experimental and not yet meant for production.

You can enable it by adding the line below to the extensions section of your hgrc:

evolve = PATH/TO/mutable-history/hgext/evolve.py

We recommend reading the documentation first. An online version is available here:

http://hg-lab.logilab.org/doc/mutable-history/html/

Or see the doc/ directory for a local copy.

Contribute

The simplest way to contribute is to issue a pull request on Bitbucket (https://bitbucket.org/marmoute/mutable-history).

However, some cutting-edge changes may be found in a mutable repository hosted by logilab before they are published.

Be sure to check latest draft changeset before submitting new changesets.
