.Dt DEVELOPMENT 7
.Os
.Sh NAME
.Nm development
.Nd quick starter for development with the DragonFly codebase
.Sh DESCRIPTION
.Dx
uses the
.Xr git 1
distributed revision control system.
If it is not already on the system, it needs to be installed via
.Xr pkgsrc 7
.Pa ( /usr/pkgsrc/devel/scmgit ) .
.Pp
The
.Sx EXAMPLES
section gives initial information to get going with development on
.Dx .
Please refer to the
.Xr git 1
manual pages and other related documents for further information on git's
capabilities and how to use them.
.Pp
For information on how to build the
.Dx
system from source code, see
.Xr build 7 .
For information on how to build a LiveCD, see
.Xr release 7 .
.Sh EXAMPLES
A fresh copy of the repository can be cloned anywhere.
Note that the directory to clone into
.Pa ( /usr/src
in the following example) must not exist, so all previous work in this
directory has to be saved and the directory be removed prior to cloning.
.Pp
To clone the repository and check out the master branch (this will take
some time):
.Bd -literal -offset 4n
cd /usr
git clone -o crater git://crater.dragonflybsd.org/dragonfly.git src
cd src
.Ed
.Pp
The repository can be held up to date by pulling frequently (to set up a
.Xr cron 8
job,
.Xr git 1 Ap s
.Fl Fl git-dir
option can be used):
.Bd -literal -offset 4n
cd /usr/src
git pull
.Ed
.Pp
It is not recommended to work directly in the master branch.
To create and checkout a working branch:
.Bd -literal -offset 4n
git checkout -b work
.Ed
.Pp
To create and checkout a branch of the
.Dx 2.0
release (called
.Sy rel2_0 ) :
.Bd -literal -offset 4n
git checkout -b rel2_0 crater/DragonFly_RELEASE_2_0
.Ed
.Pp
Branches can be deleted just as easy:
.Bd -literal -offset 4n
git branch -d work
.Ed
.Pp
After changes have been made to a branch, they can be committed:
.Bd -literal -offset 4n
git commit -a
.Ed
.Pp
.Xr git-commit 1 Ap s
.Fl m
and
.Fl F
options can be used to specify a commit message on the command line or read
it from a file, respectively.
.Pp
Finally, branches can be merged with the (updated) master by using
.Cm rebase :
.Bd -literal -offset 4n
git checkout master
git pull
git checkout work
git rebase master
.Ed
