Important notice
****************

This is totally experimental recipe for fully flexible software "build".

Examples
********

Recipe to build the software.

TODO:

* add linking suport, buildout definition:

slapos_link = <relative/path> [optional-path]

can be used as::

[file]
slapos_link =
bin/file
bin/file ${buildout:bin-directory}/bin/anotherfile

Which will link ${file:location}/bin/file to ${buildout:bin-directory}/bin/file
and ${file:location}/bin/file to ${buildout:bin-directory}/bin/anotherfile

Pure download
*************

::

[buildout]
parts =
download

[download]
recipe = slapos.recipe.build:download
url = https://some.url/file

Such profile will download https://some.url/file and put it in
buildout:parts-directory/download/download

filename parameter can be used to change destination named filename.

destination parameter allows to put explicit destination.

md5sum parameter allows pass md5sum.

mode (octal, so for rw-r--r-- use 0644) allows to set mode

Exposes target attribute which is path to downloaded file.

Notes
-----

This recipe suffers from buildout download utility issue, which will do not
try to redownload resource with wrong md5sum.



slapos.recipe.build:cpan
************************

Downloads and installs perl modules using Comprehensive Perl Archive Network (cpan).



Examples
========

Basic example
-------------

Here is example to install one or several modules::

[buildout]
parts = perl-modules

[perl-modules]
recipe = slapos.recipe.build:cpan
modules =
Class::Date
Other::Module
# Optional argument specifying perl buildout part, if existing.
# If specified, recipe will use the perl installed by buildout.
# If not specified, will take the globally available perl executable.
perl = perl

Specific version
----------------

Note that cpan won't allow you to specify version and will always take latest
version available. To choose a specific version, you will need to specify
the full path in cpan like in ::


[buildout]
parts = perl-modules

[perl-modules]
recipe = slapos.recipe.build:cpan
modules =
D/DL/DLUX/Class-Date-1.1.10.tar.gz
perl = perl

Notes
=====

Currently, the modules will be installed in site-perl directory. Location of this
directory changes depending on the perl installation.


slapos.recipe.build:npm
***********************

Downloads and installs node.js packages using Node Package Manager (NPM).

Examples
========

Basic example
-------------

Here is example to install one or several modules::

[buildout]
parts = node-package

[node-package]
recipe = slapos.recipe.build:npm
modules =
colors
express

# Optional argument specifying perl buildout part, if existing.
# If specified, recipe will use the perl installed by buildout.
# If not specified, will take the globally available perl executable.
node = node-0.6

Specific version
----------------

[buildout]
parts = node-package

[node-package]
recipe = slapos.recipe.build:cpan
modules =
express==1.0.2
node = node-0.6
