NAME
Alien - External libraries wrapped up for your viewing pleasure!
INSTALLATION
perl Build.PL
./Build
./Build test
./Build install
If you are on a windows box you should use 'nmake' rather than 'make'.
SYNOPSIS
perldoc Alien;
DESCRIPTION
Alien is a package that exists just to hold together an idea, the idea
of Alien:: packages, so there is no code here, just motivation for
Alien.
Why
So me and James ended up doing a build system for Fotango, lots of
people have done a build system, it is a pretty boring task. The boring
task is really all the mindlessly stupid things you need to do to build
C libraries that perl modules require, these C modules usually have
unusual installation systems or require vastly different options. So
CPAN modules install easy, 3rd party stuff is nasty.
So, suddenly an idea struck me, Alien packages! Imagine a CPAN module
that has as it's only task to make sure a certain library is installed!
That means that you can write all the voodoo in your Build.PL file and
then just make sure the module requires the correct Alien module! Then
anything that install perl modules will deal with it automatically!
How
So, what should an Alien module do? It should make sure that the target
is installed and it should provide the caller with enough information to
use it.
The idea is that you use it to make sure it is there, and you call class
methods to find out what to use. These class methods will be
individually specified by the stand alone Alien modules.
No Framework!
The reason this is so loosely worded is because we have no idea what
common functionality will be needed, so we will let evolution work for
us and see what individual Alien packages need and then eventually
factor it out into this packages. I would like to avoid a topdown design
approach.
Responsibilities of a Alien module.
On installation, make sure the required package is there, otherwise
install it.
On usage, make sure the required package is there, else croak.
Bundle the source with the module, or download it.
Allow module authors to access information it gathers.
Document itself well.
Preferably use Module::Build.
Be sane.
