zgeo.recipe.openlayers 0.2

Supported options

url

URL to the package that will be downloaded and extracted. The supported package formats are .tar.gz, .tar.bz2, and .zip. The value must be a full URL, e.g. http://openlayers.org/download/OpenLayers-2.7.tar.gz. The path option can not be used at the same time with url.

path

Path to a local directory containing the source code to be built and installed. The directory must contain the configure script. The url option can not be used at the same time with path.

filename

Name of javascript file to be written. Defaults to OpenLayers.js.

md5sum

MD5 checksum for the package file. If available the MD5 checksum of the downloaded package will be compared to this value and if the values do not match the execution of the recipe will fail.

patch-binary

Path to the patch program. Defaults to ‘patch’ which should work on any system that has the patch program available in the system PATH.

patch-options

Options passed to the patch program. Defaults to -p0.

patches

List of patch files to the applied to the extracted source. Each file should be given on a separate line.

keep-compile-dir

Switch to optionally keep the temporary directory where the package was compiled. This is mostly useful for other recipes that use this recipe to compile a software but wish to do some additional steps not handled by this recipe. The location of the compile directory is stored in options['compile-directory']. Accepted values are ‘true’ or ‘false’, defaults to ‘false’.

Additionally, the recipe honors the download-directory option set in the [buildout] section and stores the downloaded files under it. If the value is not set a directory called downloads will be created in the root of the buildout and the download-directory option set accordingly.

The recipe will first check if there is a local copy of the package before downloading it from the net. Files can be shared among different buildouts by setting the download-directory to the same location.

Example usage

We’ll use a simple tarball to demonstrate the recipe

>>> import os.path
>>> src = join(os.path.dirname(__file__), 'testdata')
>>> ls(src)
-  OpenLayers-2.7.tar.gz
-  README.txt

Let’s create a buildout to build and install the package

>>> write('buildout.cfg',
... """
... [buildout]
... parts = package
...
... [package]
... recipe = zgeo.recipe.openlayers
... url = file://%s/OpenLayers-2.7.tar.gz
... include =
...     OpenLayers/Map.js
...     OpenLayers/Layer/WMS.js
... """ % src)

This will download, extract and build our demo package with the default build options

Installing checkouts

Sometimes instead of downloading and building an existing tarball we need to work with code that is already available on the filesystem, for example an SVN checkout.

Instead of providing the url option we will provide a path option to the directory containing the source code.

Let’s demonstrate this by first unpacking our test package to the filesystem and building that

>>> checkout_dir = tmpdir('checkout')
>>> import setuptools.archive_util
>>> setuptools.archive_util.unpack_archive('%s/OpenLayers-2.7.tar.gz' % src,
...                                        checkout_dir)
>>> ls(checkout_dir)
d OpenLayers-2.7

>>> write('buildout.cfg',
... """
... [buildout]
... parts = package
...
... [package]
... recipe = zgeo.recipe.openlayers
... path = %s/OpenLayers-2.7
... filename = ol-wms.js
... include =
...     OpenLayers/Map.js
...     OpenLayers/Layer/WMS.js
... """ % checkout_dir)

Since using the path implies that the source code has been acquired outside of the control of the recipe also the responsibility of managing it is outside of the recipe.
