'''command to transplant changesets from another branch
|
|
|
|
|
|
This extension allows you to transplant changes to another parent revision,
|
|
|
possibly in another repository. The transplant is done using 'diff' patches.
|
|
|
|
|
|
Transplanted patches are recorded in .hg/transplant/transplants, as a
|
|
|
map from a changeset hash to its hash in the source repository.

|

|
|
|
|
Selected changesets will be applied on top of the current working
|
|
|
directory with the log of the original changeset. The changesets
|
|
|
are copied and will thus appear twice in the history with different
|
|
|
identities.
|
|
|
|
|
|
Consider using the graft command if everything is inside the same
|
|
|
repository - it will use merges and will usually give a better result.
|
|
|
Use the rebase extension if the changesets are unpublished and you want
|
|
|
to move them instead of copying them.
|
|
|
|
|
|
If --log is specified, log messages will have a comment appended
|
|
|
of the form::
|
|
|
|
|
|
(transplanted from CHANGESETHASH)
|
|
|
|
|
|
You can rewrite the changelog message with the --filter option.
|
|
|
Its argument will be invoked with the current changelog message as
|
|
|
$1 and the patch as $2.
|
|
|
|
|
|
--source/-s specifies another repository to use for selecting changesets,
|
|
|
just as if it temporarily had been pulled.
|
|
|
If --branch/-b is specified, these revisions will be used as
|
|
|
heads when deciding which changesets to transplant, just as if only
|
|
|
these revisions had been pulled.
|
|
|
If --all/-a is specified, all the revisions up to the heads specified
|
|
|
with --branch will be transplanted.
|
|
|
|
|
|
Example:
|
|
|
|
|
|
- transplant all changes up to REV on top of your current revision::
|
|
|
|
|
|
hg transplant --branch REV --all
|
|
|
|
|
|
You can optionally mark selected transplanted changesets as merge
|
|
|
changesets. You will not be prompted to transplant any ancestors
|
|
|
of a merged transplant, and you can merge descendants of them
|
|
|
normally instead of transplanting them.
|
|
|
|
|
|
Merge changesets may be transplanted directly by specifying the
|
|
|
proper parent changeset by calling :hg:`transplant --parent`.
|
|
|
|
|
|
If no merges or revisions are provided, :hg:`transplant` will
|
|
|
start an interactive changeset browser.
|
|
|
|
|
|
If a changeset application fails, you can fix the merge by hand
|
|
|
and then resume where you left off by calling :hg:`transplant
|
|
|
--continue/-c`.
