taking uncommitted changes on the wrong branch to the right branch

Question

I am using Mercurial.

I have some uncommitted changes but I am on the wrong branch, how do I update to the right branch and take the changes with me?

Answer 1

For uncommited changes you can use the Shelve extension:

1. hg shelve --all
2. hg up correct_branch_name
3. hg unshelve

Answer 2

I asked on irc

mpm said

hg diff > mychanges; hg up -C somewhere; hg import --no-commit mychanges

which I had considered but is what I was trying to avoid.

i think you can easily do it by "hg update"ing to a changeset that is a
parent of the branch you're trying to switch to, and then "hg update"ing to the
tip of that branch

so I did that.

hg up -r <shared root rev>
hg up branchIwant

I asked about "why" and was told "you are not allowed to update across branches" which didn't make sense to me at first. Then I realized that because I went through the shared root rev, it isn't across branches.
