annotate docs/from-mq.rst @ 375:1525b240d806 stable

obsolete: doc punch the hint about hg stabilize into the push error message.

The goal is to ease the transposition of to default where half of the message
may be raised by core directly.

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

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

All your work in progress is now in real changesets all the time.

You can use the standard log command to display them. You can use the
phase revset to display unfinished work only, and use templates to have
the same kind of compact that the output of qseries has.

This will result in something like that::

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

hg qnew
````````

With evolve you handle standard changesets without an additional overlay.

Standard changeset are created using hg commit as usual.::

  $ hg commit

If you want to keep the "WIP is not pushed" behavior, you want to
set 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
commits 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 options as commit, plus the switch '-e' (--edit)
to edit the commit message in an editor.

The amend command also has a -c switch which allow you to make an
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 qref -X
````````````

To remove change from you current commit use::

  $ hg uncommit not-ready.txt


hg qpop
`````````

The following command emulate the behavior of hg qpop:

  $ hg gdown

If you need to go back to an arbitrary commit you can use:

  $ hg update

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

hg qpush
````````

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

The evolution extension adds a command to rewrite the "out of sync"
changesets:::

  $ 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 allows 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 prune <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, but outside mq.



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

These are not necessary anymore. If you want to control exchange and
mutability of changesets, see the phase feature



hg qcommit
```````````````

If you really need to send patches through versioned mq patches, you should
look at the qsync extension.
