How to start developing Basie

So, first off, I think Python developers these days need to use stuff like virtualenv and zc.buildout in order to develop in a sane manner. Yeah, this is the first project I’m using them on, but do what I say, not what I do.

Anyways, on to the instructions.

sudo easy_install virtualenv
virtualenv --no-site-packages basie
cd basie/
. bin/activate

Then, you’re gonna need a buildout.cfg. Mine looks like this:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
[buildout]
parts = django
eggs = ipython

[django]
recipe = djangorecipe
version = trunk
settings = development
eggs = ${buildout:eggs}
project = basie
wsgi = true

You’ll also need a bootstrap.py, which will look a little something like this:

 1
 2
 3
 4
 5
 6
 7

"""Bootstrap a buildout-based project

Simply run this script in a directory containing a buildout.cfg.
The script accepts buildout command-line options, so you can
use the -c option to specify an alternate configuration file.

import os, shutil, sys, tempfile, urllib2

tmpeggs = tempfile.mkdtemp()

try:
    import pkg_resources
except ImportError:
    ez = {}
    exec urllib2.urlopen('http://peak.telecommunity.com/dist/ez_setup.py'
                         ).read() in ez
    ez['use_setuptools'](to_dir=tmpeggs, download_delay=0)

    import pkg_resources

if sys.platform == 'win32':
    def quote(c):
        if ' ' in c:
            return '"%s"' % c # work around spawn lamosity on windows
        else:
            return c
else:
    def quote (c):
        return c

cmd = 'from setuptools.command.easy_install import main; main()'
ws  = pkg_resources.working_set
assert os.spawnle(
    os.P_WAIT, sys.executable, quote (sys.executable),
    '-c', quote (cmd), '-mqNxd', quote (tmpeggs), 'zc.buildout',
    dict(os.environ,
         PYTHONPATH=
         ws.find(pkg_resources.Requirement.parse('setuptools')).location
         ),
    ) == 0

ws.add_entry(tmpeggs)
ws.require('zc.buildout')
import zc.buildout.buildout
zc.buildout.buildout.main(sys.argv[1:] + ['bootstrap'])
shutil.rmtree(tmpeggs)

After you’ve got those, it’s basically:

python bootstrap.py
buildout -v
django help
django runserver

And when you’re done, deactivate

Any comments on things that don’t work would be highly appreciated.
