Allows to import zip-compressed Python package by URL (http, hdfs).
Project description
Allows to import zip-compressed Python package by URL.
Download remote zip-compressed Python package, unzip and add to Python path.
All temp files will be removed on exit unless Python process was terminated.
Note: import should be called separatelly after calling importable. All we do here - just adding package to local python path.
Supported URL types
importable supports a limited set of URL types:
Http url to zip file: http(s)://<url>/<filename>.zip
The module, which you are going to import, should be located on the first level of <filename>.zip
See section Example.
Http url to zip file on GitHub: http(s)://github.com/<path>/<filename>.zip
Similar to the previous type except that module is located inside an additional directory (in <filename>.zip).
Hdfs url to zip file: webhdfs://<host>:<port>/<path>/<filename>.zip
Similar to #1 except that file will be downloaded from HDFS.
<host> - hostname or IP address of Hdfs namenode <port> - WebHdfs port of namenode
Install
Using pip:
$ pip install importable
Usage
Make remote package importable, then import it and use:
from importable import importable
# add contents of "<filename>.zip" to python path
importable('http://<url>/<filename>.zip')
# now you can import your module
import <module_name>
Example
Assuming that you have local nginx serving /var/www/html/ on port 80.
$ mkdir mymodule
$ echo "my_var = 'I want to import this one!'" > mymodule/__init__.py
$ zip -r mymodule.zip mymodule
$ mv mymodule.zip /var/www/html
Then execute the python code:
>>> import mymodule
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named 'mymodule'
>>> from importable import importable
>>> importable('http://localhost/mymodule.zip')
>>> import mymodule
>>> print(mymodule.my_var)
I want to import this one!
