bopen.recipe.libinc 0.3.0

Warning: Work in progress

This zc.buildout recipe is pre-alpha quality.

Supported options

flags-command

a list of commands that return the linking options, one per line

Example usage

We’ll use a simple config command to demonstrate the recipe.

>>> import os.path
>>> testdata = join(os.path.dirname(__file__), 'testdata')
>>> ls(testdata)
-  sample-config

The options are accessible by other recipes:

>>> mkdir(sample_buildout, 'recipes')
>>> write(sample_buildout, 'recipes', 'echo.py',
... """
... import logging
...
... class Echo:
...     def __init__(self, buildout, name, options):
...         self.name, self.options = name, options
...
...     def install(self):
...         logging.getLogger(self.name).info(self.options.get('echo', ''))
...         return ()
...
...     def update(self):
...         pass
... """)

>>> write(sample_buildout, 'recipes', 'setup.py',
... """
... from setuptools import setup
...
... setup(
...     name = "recipes",
...     entry_points = {'zc.buildout': ['echo= echo:Echo']},
...     )
... """)

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