'''Named branches''' allow assigning persistent symbolic names to branches of development inside a single ["Repository"].

== Create a Branch ==
Calling {{{hg branch}}} without a name shows the current branch name of the ["WorkingDirectory"]. Calling {{{hg branch}}} after a {{{hg init}}} outputs "default", the (reserved) name of the default branch:

{{{
$ hg branch
default
}}}

To begin a branch, set the branch name of the working directory and then ["Commit"] it:

{{{
$ hg branch newfeature
marked working directory as branch newfeature
$ hg branch
newfeature
$ hg ci -m "start feature branch"
$ hg parents
changeset: 3899:c08bfc770d37
branch: newfeature
tag: tip
user: Matt Mackall <mpm@selenic.com>
date: Tue Dec 19 14:20:11 2006 -0600
summary: start feature branch
}}}

== Commit Changes to a Branch ==
From this moment on, all commited ["ChangeSet"]s will get tagged with the supplied branch name. When ["Merge"]ing with another branch, the local branch name takes precedence:

{{{
$ hg branch
newfeature
$ hg in remote
searching for changes
changeset: 3900:3be94ff00829
branch: main
tag: tip
parent: 3898:93e5f07baf75
user: Matt Mackall <mpm@selenic.com>
date: Tue Dec 19 14:26:52 2006 -0600
summary: bug fix

$ hg pull remote
pulling from remote
searching for changes
adding changesets
adding manifests
adding file changes
added 1 changesets with 1 changes to 1 files (+1 heads)
(run 'hg heads' to see heads, 'hg merge' to merge)
$ hg merge
1 files updated, 0 files merged, 0 files removed, 0 files unresolved
(branch merge, don't forget to commit)
$ hg branch
newfeature
}}}

Branch names can be used anywhere that ["Tag"] names can, including log, diff, ["Push"], and ["Pull"]. When a branch has multiple ["Head"]s, the ["Tip"]most revision of the branch will be found. Here are some examples:

{{{
$ hg branches
main 3900:3be94ff00829
newfeature 3899:c08bfc770d37
$ hg log -r main
changeset: 3900:3be94ff00829
branch: main
tag: tip
parent: 3898:93e5f07baf75
user: Matt Mackall <mpm@selenic.com>
date: Tue Dec 19 14:26:52 2006 -0600
summary: bug fix
$ hg in -r main ../bd2
searching for changes
no changes found
}}}

== Switch between Branches ==
{{{
$ hg update -C main
$ hg update -C newfeature
}}}
