gaebuild 0.2.2

Buildout recipe for Google app engine

Description

Please send me feedback and comments to [e-mail]

Based on djbuild and code from setuptools used.

This buildout recipe can be used to create a setup for gae project. It will automatically install apps into libs directory.

You can see an example of how to use the recipe below:

[buildout]
parts = satchmo gae
eggs = ipython

[satchmo]
recipe = gocept.download
url = http://www.satchmoproject.com/snapshots/satchmo-0.6.tar.gz
md5sum = 659a4845c1c731be5cfe29bfcc5d14b1

[gae]
recipe = gaebuild
settings = development
eggs = ${buildout:eggs}
project = dummyshop

Supported options

The recipe supports the following options.

apps

projects that can be installed using pypi or compressed files. No handle dependencies do it by hand using buildout, the decision was taken for these reasons:

• if dependency is a gae/django app this should be declared into this option to install it into the extarnal-apps directory or it should be omited if the dependency was customized and it is on local-apps directory

• if dependency is not a gae/django app this should be declared into libs option.

To delete an application should be by hand.

project

This option sets the name for your project. The recipe will create a basic structure if the project is not already there.

external-apps

This option sets the directory where external reusable apps goes. Which do not be installed as an egg or if you don’t want install it as an egg.

local-apps

This option sets the directory where local reusable apps goes, usually put the company name for this directory, and customized apps.

python

This option can be used to specify a specific Python version which can be a different version from the one used to run the buildout.

settings

You can set the name of the settings file which is to be used with this option. This is useful if you want to have a different production setup from your development setup. It defaults to development. if turboengine is setup

download-cache

Set this to a folder somewhere on you system to speed up installation. The recipe will use this folder as a cache for a downloaded version of Django.

libs-path

Path specified here will be used to install python projects

script-dir

Paths specified here will be used to extend the default Python path for the bin/* scripts. default ‘bin’ some common scripts will be wsdl2py used for webservices and ZSI

find-links

used to install apps inside the project

turboengine

use turboengine set the version or ‘last’ for last version

webservices

set true to use turboengines webservices wrapper, gaebuild will install ZSI and zope.interface only avaible if turboengine is used, default false

libs

pure python libraries to install into libs-dir, default lib

zipped

true for install compressed eggs(libs) format or false as directory default false.

All following options only have effect when the project specified by the project option has not been created already, on the setting file especified.

Notes.-

• If use turboengine don’t edit app.py if generated authomaticaly by the recipe but Please edit webservices.py only generated once.

• If not edit app.py first extending pythonpath if you change this variables: local-apps, extarnal-apps libs-dir

• If some app or project has error on its setup.py file the process is terminated

Another example

The next example shows you how to use some more of the options:

[buildout]
parts = gae extras
eggs =
  hashlib

[extras]
recipe = iw.recipe.subversion
urls =
  http://django-command-extensions.googlecode.com/svn/trunk/ django-command-extensions
  http://django-mptt.googlecode.com/svn/trunk/ django-mptt

[gae]
recipe = gaebuild
settings = development
project = exampleproject
eggs =
  ${buildout:eggs}

Example with a different Python version

To use a different Python version from the one that ran buildout in the generated script use something like:

[buildout]
parts = myproject

[special-python]
executable = /some/special/python

[myproject]
recipe        = gaebuild
project       = myproject
python        = special-python
