                       copied from to FILE
  --export           : used with --checkout to create a detached copy
  --offline          : takes the current branch offline, making a copy
                       under //local
  --online           : takes the current branch online, pushing changes back
                       to the mirror path, and then switches to the mirror
 
 

DESCRIPTION

SVK provides tools to more easily manage your project's branching and merging, so long as you use the standard ``trunk/, branches/, tags/'' directory layout for your project or specifically tell SVK where your branches live.

Usage (without projects)

A very simple sample usage might be to checkout the trunk from a project you want to work on but don't have upstream commit rights for. This allows you to maintain a local branch and to send in patches.

Assuming you have alread mirrored this repository to //mirror/Project

     svk co //mirror/Project/trunk
 or
     svk branch --co trunk //mirror/Project/
 
 

and then

     svk branch --offline
 
 

You're now working in a local branch, make local commits and changes as you need to. If you want to bring in changes from your remote repository, you can pull them down

     svk branch --pull
 
 

To see what changes you've made, you can create a patch between the local branch and the remote repository

     svk branch -P - --push
 
 

If you have commit rights to the remote repository, you can also

     svk branch --push
 
 

to send your changes.

You can use svk branch's branching capability in this mode, but it will be much friendlier if you set up a project

Usage (projects)

To initialize a project in a repository, run the setup command

     svk branch --setup //mirror/Project
 
 

If you have the standard trunk branches tags directories svk will offer them as the starting point. In fact, if you have trunk branches and tags directories, svk will try to use them without neeting --setup, but you won't be able to use the --project flag and will need to use depotpaths in commands.

The rest of this documentation assumes you've set up a project called Example in //mirror/Project

If you're in a working copy of svk where it can work out the Project name, you can leave off the --project flag from the examples below, but you can branch/tag/merge without having working copies

Branching

To check out the trunk, you can run

     svk branch --co trunk --project Example
 
 

To create a branch for release engineering

     svk branch --create Exmaple-1.0-releng --project Example
 
 

Since you have a checkout of trunk already, you can convert that

     cd trunk
     svk branch --switch-to Example-1.0-releng
 
 

Or you can get a clean checkout

     svk branch --co Example-1.0-releng --project Example
 
 

If changes are made on trunk and you wish to bring them down to the release engineering branch, you can do that with the branch merge command

     svk branch --merge trunk Example-1.0-releng
 
 

If you're cautious, use the check flags first:

     svk branch -C --merge trunk Example-1.0-releng
     svk branch -P -  --merge trunk Example-1.0-releng
 
 

These will show you what svk wants to do.

Lets say you want to add a feature to trunk but work on a branch so you don't inconvenience others who are working on trunk:

     svk branch --create Feature --project Example
 
 

work on your feature, svk ci some changes

     svk branch --merge Feature trunk --project Example
 
 

continue to bring down changes several ways

     svk branch --pull
     svk branch --merge trunk Feature
     svk branch --merge trunk .   (if you're in a working copy of the branch)
 
 

and then merge back more feature work as you need to

To get rid of a branch when you're done with it

     svk branch --delete Feature --project Example
 
 

To see all of your branches, you can do:

     svk branch --list --project Example
 
 

Tagging

If you've been working on your releng branch and are ready to cut a release, you can easily create a tag

     svk branch --tag --create 1.0rc1 --from Example-1.0-releng --project Example
 
 

If you would like to check out this tag, use

     svk branch --tag --co 1.0rc1 --project Example
 
 

Project Property Details

SVK branch also provides another project loading mechanism by setting properties on root path. Current usable properties for SVK branch are

   'svk:project:<projectName>:path-trunk'
   'svk:project:<projectName>:path-branches'
   'svk:project:<projectName>:path-tags'
 
 

These properties are useful when you are not using the standard ``trunk/, branches/, tags/'' directory layout. For example, a mirrored depotpath '//mirror/projA' may have trunk in ``/trunk/projA/'' directory, branches in ``/branches/projA'', and have a standard ``/tags'' directory. Then by setting the following properties on root path of remote repository, it can use SVK branch to help manage the project:

   'svk:project:projA:path-trunk => /trunk/projA'
   'svk:project:projA:path-branches => /branches/projA' 
   'svk:project:projA:path-tags => /tags'
 
 

Be sure to have all ``path-trunk'', ``path-branches'' and ``path-tags'' set at the same time.
