Initializing test env.

Generating all scripts

Thus by not specifying any scripts entry in the buildout part.

>>> data = """
... [buildout]
... download-cache=${buildout:directory}/dl
... parts = part
... [part]
... recipe=minitage.recipe.scripts
... find-links=%(index)s
... eggs=foo
... """%{'index': index_url}
>>> touch('buildout.cfg', data=data)
>>> noecho = [remove(os.path.join('eggs', egg)) for egg in os.listdir('eggs') if 'foo' in egg]
>>> sh('bin/buildout -vvvvv install')
b...
minitage.recipe: Got foo 1.0.
minitage.recipe: Picked: foo = 1.0
minitage.recipe: All egg dependencies seem to be installed!
minitage.recipe: Generated scripts: 's', 'toto.py'...

Look at what have been generated.

>>> cat('bin', 'toto.py')
#!...
# ! GENERATED BY minitage.recipe !
import os
import sys
import subprocess...
sys.path[0:0] = ['/tmp/buildout.test/eggs/foo-1.0-py....egg' ]...
# EXEC ORGINAL CODE WITHOUT SHEBANG
__doc__  = 'I am generated by minitage.recipe.script recipe'...
os.environ['PYTHONPATH'] = ':'.join(sys.path + os.environ.get('PYTHONPATH', '').split(':'))
sys.argv.pop(0)
sys.exit(
    subprocess.Popen(
        [sys.executable, '/tmp/buildout.test/eggs/foo-1.0-py....egg/EGG-INFO/scripts/toto.py']+sys.argv,
        env=os.environ
    ).wait()
)...

Selecting scripts to install

Installing only s.

>>> data = """
... [buildout]
... download-cache=${buildout:directory}/dl
... parts = part
... [part]
... recipe=minitage.recipe.scripts
... find-links=%(index)s
... scripts =

... eggs=foo
... """%{'index': index_url}
>>> touch('buildout.cfg', data=data)
>>> sh('bin/buildout -vvvvv install')
b...
minitage.recipe: Generated scripts: 's'....

Installing only toto.py.

>>> data = """
... [buildout]
... download-cache=${buildout:directory}/dl
... parts = part
... [part]
... recipe=minitage.recipe.scripts
... find-links=%(index)s
... scripts =

... """%{'index': index_url}
>>> touch('buildout.cfg', data=data)
>>> sh('bin/buildout -vvvvv install')
b...
minitage.recipe: Generated scripts: 'toto.py'....

Declaring entry-points

We ll add an entry point ‘t’ to be generated.

>>> data = """
... [buildout]
... download-cache=${buildout:directory}/dl
... parts = part
... [part]
... recipe=minitage.recipe.scripts
... find-links=%(index)s
... entry-points=t=toto.toto:f
... eggs=foo
... """%{'index': index_url}
>>> touch('buildout.cfg', data=data)
>>> sh('bin/buildout -vvvvv install')
b...

Adding initialization code

What about adding environment variables for gis env.

>>> data = """
... [buildout]
... download-cache=${buildout:directory}/dl
... parts = part
... [part]
... recipe=minitage.recipe.scripts
... find-links=%(index)s
... entry-points=t=toto.toto:f
... eggs=foo
... initialization = import os;os.environ.set('GDAL', 'TRUE')
... """%{'index': index_url}

>>> sh('bin/buildout -vvvvv install')
b...

>>> "import os;os.environ.set('GDAL', 'TRUE')" in open(os.path.join('bin', 't')).read()
True

Adding arguments

What about adding arguments to our launchers.

>>> data = """
... [buildout]
... download-cache=${buildout:directory}/dl
... parts = part
... [part]
... recipe=minitage.recipe.scripts
... find-links=%(index)s
... eggs = foo
... entry-points=t=toto.toto:f
... arguments = ['a', 'b']
... """%{'index': index_url}
>>> touch('buildout.cfg', data=data)
>>> sh('bin/buildout -vvvvv install')
b...

>>> "toto.toto.f(['a', 'b'])" in open(os.path.join('bin', 't')).read()
True

Generating a python interpreter

Here is how you can generate a specific python interpreter will all the environement of the working set.

>>> data = """
... [buildout]
... download-cache=${buildout:directory}/dl
... parts = part
... [part]
... recipe=minitage.recipe.scripts
... find-links=%(index)s
... interpreter = mypy
... arguments = ['a', 'b']
... eggs=foo
... """%{'index': index_url}
>>> touch('buildout.cfg', data=data)
>>> sh('bin/buildout -vvvvv install')
b...
minitage.recipe: Generated scripts: 'mypy'....

>>> cat('bin', 'mypy')
#!...
#!!! #GENERATED VIA MINITAGE.recipe !!!...
sys.path[0:0] = [ '/tmp/buildout.test/eggs/foo-1.0-py....egg' ]...
if _interactive:
    import code
    code.interact(banner="", local=globals())...

Generating an envrionment file

Here is how you can generate a specific envrionment file that you can source from to get the PYTHONPATH populated with eggs that you have configured.

>>> data = """
... [buildout]
... download-cache=${buildout:directory}/dl
... parts = part
... [part]
... recipe=minitage.recipe.scripts
... find-links=%(index)s
... env-file = mypy
... eggs=foo
... """%{'index': index_url}
>>> touch('buildout.cfg', data=data)
>>> sh('bin/buildout -vvvvv install')
b...
minitage.recipe: Generated scripts: '/tmp/buildout.test/bin/mypy'....

>>> cat('bin', 'mypy')
#!/usr/bin/env sh
<BLANKLINE>
PYTHONPATH="/tmp/buildout.test/eggs/foo-1.0-py....egg:$PYTHONPATH"
export PYTHONPATH
