在mercurial中使用默认分支切换分支

Question

在我正在工作的仓库中，我们在某个时间创建了一个命名分支，以便在某个问题上尝试不同的方法。我们继续在默认分支中工作。

既然命名分支已经成熟，我们想要创建那个分支，默认分支，并为（旧）默认分支指定一个不同的名称。

这样的事情可能吗？

我发现了这个问题Mercurial: Can I rename a branch?，我可以成功重命名默认分支，但之后当我尝试将命名分支重命名为默认分支时，它失败并显示错误

abort: a branch of the same name already exists

Answer 1

是的，你可以。

您需要关闭所有分支，然后为其提供所需的名称

PS：好像你只需要在分支命令

中添加-f标志

示例场景

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"

结果：

>hg log -G
