How to tag and goes to a tag in hg

Question

Hi,

From here, it said hg tag 1.0 is to get my Mercurial repository to a tag name.

How can I switch my repository to that tag name?

$ hg tag myTag1.0
$ <edit more files>
$ hg commit -m "a message"
$ hg how to go back to that tag?

and if I make a new hg commit here, what will happen? Will it goes to the branch of myTag1.0? Or it will stay with default branch?

Thank you.

Tags are not branches. Tags are markers for a particular commit - basically, a way to name commits. That's all. You don't "switch a repository to a tag" any more than you would "switch a repository to a commit" - you can check out a tag, but all that does is roll back your working copy to the corresponding changeset which was tagged.

Branches are created automatically in Mercurial when you commit code that doesn't directly build off of the current head revision.

Just update to the tag name.

hg tag 1.0
... make changes ...
hg ci
hg up 1.0
