Cherry Picking With Mercurial
Merging a full branch in mercurial is quite easy.
hg update <target branch name> hg merge <merging branch name>
But if you would like to just merge in a few of the revisions from a branch and not the whole thing you need to what is called cherry picking in git, but transplanting in mercurial. Transplanting isn't a default action in mercurial, but the extension to enable it does come by default. To enable the transplant extension open your hg config file
And add the line transplant= under your [extensions]
Now take a look at your logs to get the numbers for the revisions you'd like to move.
hg log -b <merging branch name>
Take note of which you'd like to merge and run
hg update <target branch name> hg transplant -b <merging branch name> <rev1> <rev2>
As an example if we'd like to merge revisions 1156, 1157 and 1162 from the customers branch into default we'd use the following
hg update default hg transplant -b customers 1156 1157 1162
