Replacement details
---------------------

hg qseries
```````````

All your work in progress are now real changeset all the time.

You can then use standard log to display them. You can use phase revset to
display unfinished business only and template to have the same kind of compact
output qseries have.

This will result in something like that::

  [alias]
  wip = log -r 'not public()' --template='{rev}:{node|short} {description|firstline}\n'

hg qnew
````````

With evolve you handle standard changeset without additional overlay.

Standard changeset are created using hg commit as usual.

  $ hg commit

If you want to keep the "wip are not pushed" behavior, you are looking for
setting your changeset in the secret phase using the phase command.

Note that you only need it for the first commit you want to be secret. Later
commit will inherit their parents phase.

If you always want your new commit to be in the secret phase, your should
consider updating your configuration:

  [phases]
  new-commit=secret

hg qref
````````

A new command from evolution will allow you to rewrite the changeset you are
currently on. just call:

  $ hg amend


This command takes the same option than commit  plus useful switch '-e' (--edit)
to edit the commit message.

Amend have also a -c switch which allow you to make and explicit amending
commit before rewriting a changeset.

  $ hg record -m 'feature A'
  # oups, I forget some stuff
  $ hg record babar.py
  $ hg amend -c .^ # .^ refer to "working directoy parent, here 'feature A'

note: refresh is an alias for amend

hg qpop
`````````

the following command emule the behavior of hg qpop:

  $ hg gdown

If you need to go back to an arbitrary commit you can just us:

  $ hg update

.. note:: gdown and update allow movement with working directory changes applied
          and gracefully merge them.

hg qpush
````````

When you rewrite changeset, descendant of rewritten changeset are marked as
"out of sync". You new to rewrite them on top of the new version of their
ancestor.

The evolution extension add a command to rewrite the next changeset:

  $ hg stabilize

You can also decide to do it manually using

  $ hg graft -O <old-version>

or 

  $ hg rebase -r <revset for old version> -d .

note: using graft allow you to pick the changeset you want next as the --move
option of qpush do.


hg qrm
```````

evolution introduce a new command to mark a changeset as "not wanted anymore".

  $ hg kill <revset>

hg qfold
`````````


::

  $ hg up <top changeset>
  $ amend --edit -c <bottom changeset>


or later::

  $ hg collapse # XXX not implemented

  $ hg rebase --collapse # XXX not tested


hg qdiff
`````````

``odiff`` is an alias for `hg diff -r .^` it works as qdiff event outside mq.



hg qfinish and hg qimport
````````````````````````````

Is not useful anymore if you want to controll exchange and mutability of
changeset see the phase feature
