What is iw.recipe.fetcher ?

Download an url to a local directory.

How to use iw.recipe.fetcher ?

The recipe download from an http server:

>>> server_data = tmpdir('server_data')
>>> write(server_data, 'file1.txt', 'test1')
>>> write(server_data, 'file2.txt', 'test1')
>>> write(server_data, 'file3.txt', 'test1')

>>> server_url = start_server(server_data)

We need some buildout vars:

>>> write('buildout.cfg', '''
... [buildout]
... parts=test1
...
... [test1]
... recipe=iw.recipe.fetcher
... urls=
...       %(server_url)s/file1.txt
... base_url=%(server_url)s
... files=
...       file2.txt
...       file3.txt
... ''' % dict(server_url=server_url))

Now we can fetch some urls:

>>> print system(buildout)
Installing test1.
<BLANKLINE>

It works:

>>> ls(sample_buildout, 'test1')
- file1.txt
- file2.txt
- file3.txt


>>> write('buildout.cfg', '''
... [buildout]
... parts=test2
...
... [test2]
... recipe=iw.recipe.fetcher
... urls=
...   http://www.example.com/file1.txt
... find-links=%(server_url)s
... ''' % dict(server_url=server_url))

Now we can fetch some urls:

>>> print system(buildout)
Uninstalling test1.
Installing test2.
