Usage:

import sys, urlimport urlimport.config(**{ 'ssl_key.https://your.url':'key for this url' 'ssl_cert.https://your.url':'cert for this url', 'opener.https://your.url':'opener for this url', 'cache_time.http://your.url':'timedelta to keep files in cache for this url', 'no_cache.url':True, # don't cache modules from this url 'user_agent.url':'user agent header for this url', 'ssl_key.host':'key for this host' 'ssl_cert.host':'cert for this host', 'opener.host':'opener for this host', 'cache_time.host':'timedelta to keep files in cache for this host', 'no_cache.host':True, # don't cache modules from this host 'user_agent.host':'user agent header for this host', 'ssl_key':'key for unspecified urls', 'ssl_cert':'cert for unspecified urls', 'opener':'opener for unspecified urls', 'no_cache':'True, #don't cache modules for unspecified urls 'user_agent':'user agent header for unspecified urls', 'cache_time':'timedelta to keep files in cache for unspecified urls', #if cache_time is missing, keep forever, but check last_modified and etag 'cache_dir':'root of the cache dir', # if missing, a temp dir will be created, # if empty, no cache will be used 'py_version_string': '$PYTHON_VERSION', # string in path to be replaced by # $major.$minor 'debug': int(level of output text. see debug() function) })

note: if you supply your own opener, i'd recommand inheriting/implementing the

status handling features from class DefaultErrorHandler below.

sys.path.insert(0, "http://your.url") #this may already be there, like setting #PYTHONPATH #but there is a danger default import #would try it before expect to have access to your modules at http://your.url

TODO:

• check what's mpath all about.

TODO later:

• python 3.1 support. preliminary work done
• url import of zipped modules
• support of other urls, like ssh, svn, hg, bzr, cvs etc.
• reload c extensions. well, they don't allways reload in local import either, but my module does reload locally, so why not remotely? introspection will help.
• swithch the usage of debug with some logging, and do some cleanup of the calls.
