mercurial - Switch branches with default branch in mercurial

Question

In a repo I'm working, we created a named branch at some time to try a different approach in a certain issue. We continued to work in the default branch as well.

Now that the named branch has matured so to speak, we would like to make that branch, the default one, and give a different name for the (old) default branch.

Is something like that possible?

I've found this question, Mercurial: Can I rename a branch? and I can rename the default branch successfully, but afterwards when I try to rename the named branch to default, it fails with an error

abort: a branch of the same name already exists

Answer 1

はい、できます。

すべてのブランチを閉じてから、必要な名前を付ける必要があります

-fPS：ブランチコマンドにフラグを追加する必要があったようです

サンプル シナリオ

hg init
echo "123" > file
hg addremove
hg commit -m "init default"

hg branch new
echo "new" >> file
hg commit -m "init new"

hg up default
echo "default" >> file
hg commit -m "default 2nd"
hg commit --close-branch -m "close default"


hg up new
hg commit --close-branch -m "close new"

hg branches # none

hg log # see where to update if haven't saved id/hash somewhere

hg up 3 # this changset was the "close default" one
hg branch new -f
hg commit -m "new new"

hg up 4 # the changeset we closed "new" at
hg branch default -f
hg commit -m "new default"

結果：
