.TH "EBUILD" "5" "Feb 2003" "Portage 2.0.51" "portage"
.SH "NAME"
ebuild \- the internal format, variables, and functions in an ebuild script
.SH "DESCRIPTION"
The
.BR ebuild (1)
program accepts a single ebuild script as an argument.  This script
contains variables and commands that specify how to download, unpack,
patch, compile, install and merge a particular software package from
its original sources.  In addition to all of this, the ebuild script
can also contain pre/post install/remove commands, as required.
.SH "EXAMPLES"
Here's a simple example ebuild:

.SH "VARIABLES"
.TP
.B MISC USAGE NOTES
- PORTAGE* and PORTDIR* variables may be found in \fBmake.conf\fR(5).
.br
- When assigning values to variables in ebuilds, you \fBcannot have a space\fR
between the variable name and the equal sign.
.TP
.B P
This variable contains the package name without the ebuild revision.
This variable must NEVER be modified.
.br
\fBxfree-4.2.1-r2.ebuild\fR --> \fB$P\fR=='\fIxfree-4.2.1\fR'
.TP
.B PN
Contains the name of the script without the version number.
.br
\fBxfree-4.2.1-r2.ebuild\fR --> \fB$PN\fR=='\fIxfree\fR'
.TP
.B PV
Contains the version number without the revision.
.br
\fBxfree-4.2.1-r2.ebuild\fR --> \fB$PV\fR=='\fI4.2.1\fR'
.TP
.B PR
Contains the revision number or 'r0' if no revision number exists.
.br
\fBxfree-4.2.1-r2.ebuild\fR --> \fB$PR\fR=='\fIr2\fR'
.TP
.B PVR
Contains the version number with the revision.
.br
\fBxfree-4.2.1-r2.ebuild\fR --> \fB$PVR\fR=='\fI4.2.1-r2\fR'
.TP
.B PF
Contains the full package name \fI[PN]\-[PVR]\fR
.br
\fBxfree-4.2.1-r2.ebuild\fR --> \fB$PF\fR=='\fIxfree-4.2.1-r2\fR'
.TP
.B A
Contains all source files required for the package.  This variable must
not be defined. It is autogenerated from the \fISRC_URI\fR variables.
.TP
\fBWORKDIR\fR = \fI"${PORTAGE_TMPDIR}/portage/${PF}/work"\fR
Contains the path to the package build root.  Do not modify this variable.
.TP
\fBFILESDIR\fR = \fI"${PORTDIR}/${CATEGORY}/${PN}/files"\fR
Contains the path to the 'files' sub folder in the package specific
location in the portage tree.  Do not modify this variable.
.TP
\fBS\fR = \fI"${WORKDIR}/${P}"\fR
Contains the path to the temporary \fIbuild directory\fR.  This variable
is used by the functions \fIsrc_compile\fR and \fIsrc_install\fR.  Both
are executed with \fIS\fR as the current directory.  This variable may
be modified to match the extraction directory of a tarball for the package.
.TP
\fBT\fR = \fI"${PORTAGE_TMPDIR}/portage/${PF}/temp"\fR
Contains the path to a \fItemporary directory\fR.  You may use this for
whatever you like.
.TP
\fBD\fR = \fI"${PORTAGE_TMPDIR}/portage/${PF}/image"\fR
Contains the path to the temporary \fIinstall directory\fR.  Every write 
operation that does not involve the helper tools and functions (found below) 
should be prefixed with ${D}.  Do not modify this variable.  This will not be 
available inside of the pkg_* functions.
.TP
\fBDESCRIPTION\fR = \fI"A happy little package"\fR
Should contain a short description of the package.
.TP
\fBSRC_URI\fR = \fI"http://happy.com/little/${P}.tar.gz"\fR
Contains a list of URI's for the required source files.  It can contain
multiple URI's for a single source file.  The fastest location is chosen
if the file was not found at \fIGENTOO_MIRROR\fB\fR.
.TP
\fBHOMEPAGE\fR = \fI"http://happy.com/"\fR
Should contain a list of URL's for the sources main sites and other further
package dependent information.
.TP
\fBKEYWORDS\fR = \fI[-~][x86,ppc,sparc,mips,alpha,arm,hppa]\fR
Should contain appropriate list of arches that the ebuild is know to
work/not work.  By default if you do not know if an ebuild runs under
a particular arch simply omit that KEYWORD.  If the ebuild will not
work on that arch include it as \-ppc for example.  If the ebuild is
being submitted for inclusion, it must have ~arch set for architectures
where it has been PROVEN TO WORK.  (Packages KEYWORDed this way may be
unmasked for testing by setting ACCEPT_KEYWORDS="~arch" on the command
line, or in \fBmake.conf\fR(5)) For an authoritative list please review
/usr/portage/profiles/arch.list.
.TP
\fBSLOT\fR
This sets the SLOT for packages that may need to co\-exist.  By default
you should set \fBSLOT\fR="0" unless you know what you are doing and need
to do otherwise.  This value should \fINEVER\fR be left undefined.
.TP
\fBLICENSE\fR
This should be a space delimited list of licenses that the package falls
under.  This \fB_must_\fR be set to a matching license in
/usr/portage/licenses/. If the license does not exist in portage yet you
must add it first.
.TP
\fBIUSE\fR
This should be a list of any and all USE flags that are leveraged within
your build script.  The only USE flags that should not be listed here are
arch related flags (see \fBKEYWORDS\fR).
.TP
\fBDEPEND\fR
This should contain a list of all packages that are required for the
program to compile.
.RS
.TP
.B DEPEND Atoms
A depend atom is simply a dependency that is used by portage when calculating
relationships between packages.  Please note that if the atom has not already
been emerged, then the latest version available is matched.
.RS
.TP
.B Atom Bases
The base atom is just a full category/packagename.  Hence, these are base atoms:

.nf
.I sys-apps/sed
.I sys-libs/zlib
.I net-misc/dhcp
.fi
.TP
.B Atom Versions
It is nice to be more specific and say that only certain versions of atoms are
acceptable.  Note that versions must be combined with a prefix (see below).  Hence
you may add a version number as a postfix to the base:

.nf
sys-apps/sed\fI-4.0.5\fR
sys-libs/zlib\fI-1.1.4-r1\fR
net-misc/dhcp\fI-3.0_p2\fR
.fi

Versions are normally made up of two or three numbers separated by periods, such 
as 1.2 or 4.5.2.  This string may be followed by a character such as 1.2a or 4.5.2z.  
Note that this letter is \fBnot\fR meant to indicate alpha, beta, etc... status.  
For that, use the optional suffix; either _alpha, _beta, _pre (pre-release), _rc 
(release candidate), or _p (patch).  This means for the 3rd pre-release of a package, 
you would use something like 1.2_pre3.
.TP
.B Atom Prefix Operators [> >= = <= <]
Sometimes you want to be able to depend on general versions rather than specifying
exact versions all the time.  Hence we provide standard boolean operators:

.nf
\fI>\fRmedia-libs/libgd-1.6
\fI>=\fRmedia-libs/libgd-1.6
\fI=\fRmedia-libs/libgd-1.6
\fI<=\fRmedia-libs/libgd-1.6
\fI<\fRmedia-libs/libgd-1.6
.fi
.TP
.B Extended Atom Prefixes [!~] and Postfixes [*]
Now to get even fancier, we provide the ability to define blocking packages and
version range matching.  Also note that these extended prefixes/postfixes may
be combined in any way with the atom classes defined above.  Here are some common
examples you may find in the portage tree:

.nf
\fI!\fRapp-text/dos2unix
=dev-libs/glib-2\fI*\fR
\fI!\fR=net-fs/samba-2\fI*\fR
\fI~\fRnet-libs/libnet-1.0.2a
.fi

\fI!\fR means block packages from being installed at the same time.
.br
\fI*\fR means match any version of the package so long as the specified base 
is matched.  So with a version of '2*', we can match '2.1', '2.2', '2.2.1', 
etc... and not match version '1.0', '3.0', '4.1', etc...
.br
\fI~\fR means match any revision of the base version specified.  So in the 
above example, we would match versions '1.0.2a', '1.0.2a-r1', '1.0.2a-r2', 
etc...
.RE
.TP
.B Dynamic DEPENDs
Sometimes programs may depend on different things depending on the USE
variable.  Portage offers a few options to handle this.  Note that when
using the following syntaxes, each case is considered as 1 Atom in the
scope it appears.  That means that each Atom both conditionally include
multiple Atoms and be nested to an infinite depth.
.RS
.TP
.B usevar? ( DEPEND Atom )
To include the jpeg library when the user has jpeg in \fBUSE\fR, simply use the
following syntax:
.br
.B jpeg? ( media-libs/jpeg)
.TP
.B !usevar? ( Atom )
If you want to include a package only if the user does not have a certain option
in their \fBUSE\fR variable, then use the following syntax:
.br
.B !nophysfs? ( dev-games/physfs )
.br
This is often useful for those times when you want to want to add optional support
for a feature and have it enabled by default.
.TP
.B usevar? ( Atom if true ) !usevar? ( Atom if false )
For functionality like the tertiary operator found in C you must use
two statements, one normal and one inverted.  If a package uses

.B || ( Atom Atom ... )
When a package can work with a few different packages but a virtual is not 
appropriate, this syntax can easily be used.
.nf
.B || (
.B 	app-games/unreal-tournament
.B 	app-games/unreal-tournament-goty
.B )
.fi
Here we see that unreal-tournament has a normal version and it has a goty version.  
Since they provide the same base set of files, another package can use either.  
Adding a virtual is inappropriate due to the small scope of it.
.br
Another good example is when a package can be built with multiple video 
interfaces, but it can only ever have just one.
.nf
.B || (
.B 	sdl? ( media-libs/libsdl )
.B 	svga? ( media-libs/svgalib )
.B 	opengl? ( virtual/opengl )
.B 	ggi? ( media-libs/libggi )
.B 	virtual/x11
.B )
.fi
Here only one of the packages will be chosen, and the order of preference is 
determined by the order in which they appear.  So sdl has the best chance of being 
chosen, followed by svga, then opengl, then ggi, with a default of X if the user 
does not specify any of the previous choices.
