appfy.recipe.gae 0.3

Buildout recipes for App Engine development.

appfy.recipe.gae

appfy.recipe.gae provides a series of zc.buildout recipes to help App Engine development. It is inspired by rod.recipe.appengine, but using a different layout and with extended functionalities. It is also split in different recipes. Currently appfy.recipe.gae has 3 recipes:

appfy.recipe.gae:sdk:

Downloads and installs the App Engine SDK.

appfy.recipe.gae:tools:

Installs a python executable and several SDK scripts in the buildout directory: appcfg, bulkload_client, bulkloader, dev_appserver and remote_api_shell. It also allows to set default values to start the dev_appserver.

appfy.recipe.gae:app_lib:

Downloads libraries from PyPi and installs in the app directory.

Source code and issue tracker can be found at http://code.google.com/p/appfy/.

appfy.recipe.gae:app_lib

Downloads libraries from PyPi and installs in the app directory. This recipe extends zc.recipe.egg so all the options from that recipe are also valid.

Options

eggs:

Package names to be installed.

lib-directory:

Destination directory for the libraries. Default is distlib.

primary-lib-directory:

The main directory used for libraries. This is only used to create a README.txt inside lib-directory with a warning. Default is lib.

use-zipimport:

If true, a zip file with the libraries is created instead of a directory. The zip filename will be the value of lib-directory plus .zip.

ignore-globs:

A list of glob patterns to not be copied from the library.

delete-safe:

Checks the checksum of the destination directory before deleting. It will require manual deletion if the checksum from the last build differs. Default to true.

Example

[app_lib]
# Sets the library dependencies for the app.
recipe = appfy.recipe.gae:app_lib
lib-directory = app/distlib
use-zipimport = false

# Define the libraries.
eggs =
    babel
    jinja2
    wtforms
    werkzeug
    gaepytz
    gaema
    tipfy

# Don't copy files that match these glob patterns.
ignore-globs =
    *.c
    *.pyc
    *.pyo
    */test
    */tests
    */testsuite
    */django
    */sqlalchemy

appfy.recipe.gae:sdk

Downloads and installs the App Engine SDK in the buildout directory. This recipe extends hexagonit.recipe.download so all the download options from that recipe are also valid.

Options

destination:

Destination of the extracted SDK download. Default is ${buildout:parts-directory}/google_appengine.

clear-destination:

If true, deletes the destination dir before extracting the download. Default is false.

Example

[gae_sdk]
# Dowloads and extracts the App Engine SDK.
recipe = appfy.recipe.gae:sdk
url = http://googleappengine.googlecode.com/files/google_appengine_1.3.3.zip
destination = ${buildout:parts-directory}/google_appengine
strip-top-level-dir = true
hash-name = false
clear-destination = true

appfy.recipe.gae:tools

Installs a python executable and several SDK scripts in the buildout directory: appcfg, bulkload_client, bulkloader, dev_appserver and remote_api_shell.

It also allows to set default values to start the dev_appserver.

This recipe extends zc.recipe.egg so all the options from that recipe are also valid.

Options

sdk-directory:

Path to the App Engine SDK directory. It can be an absolute path or a reference to the appfy.recipe.gae:sdk destination option. Default is ${buildout:parts-directory}/google_appengine.

appcfg-script:

Name of the appcfg script to be installed in the bin directory.. Default is appcfg.

bulkload_client-script:

Name of the bulkloader script to be installed in the bin directory. Default is bulkload_client.

bulkloader-script:

Name of the bulkloader script to be installed in the bin directory. Default is bulkloader.

dev_appserver-script:

Name of the dev_appserver script to be installed in the bin directory. Default is dev_appserver.

remote_api_shell-script:

Name of the remote_api_shell script to be installed in the bin directory. Default is remote_api_shell.

config-file:

Configuration file with the default values to use in scripts. Default is script_defaults.cfg.

Example

[gae_tools]
# Installs appcfg, dev_appserver and python executables in the bin directory.
recipe = appfy.recipe.gae:tools
sdk-directory = ${gae_sdk:destination}

Note that this example references an gae_sdk section from the appfy.recipe.gae:sdk example. An absolute path could also be used.

To set default values to start the dev_appserver, create a section dev_appserver in the defined configuration file (script_defaults.cfg by default). For example:

[dev_appserver]
# Set default values to start the dev_appserver. All options from the
# command line are allowed. They are inserted at the beginning of the
# arguments. Values are used as they are; don't use variables here.
defaults =
    --datastore_path=var
    --history_path=var
    --blobstore_path=var
    app

These options can be set in a single line as well. If an option is provided when calling dev_appserver, it will override the default value if it is set.

Versions
