Import functions from external file using pyplugs

[AndresLaverdeMarin]

Hi,

I want import extarnal function from my code to modify some characteristics of the code. I have the following structure inside of my code:

plugins/
     __init__.py

And I want o import the function sum defined in external file inside of plugins, This is possible? I can import a completely external funciton to modify my code using pyplugs?

In other words my question is how I can register a external funcion using pyplugs? Can I use pyplugs.get to get an external funcion? Or How I can use pyplugs.register to register this external function?

Hi @AndresLaverdeMarin

You can do pyplugs.register(external_func) to register an external function where you can't use the normal decorator syntax. For example:

>>> import pathlib
>>> pathlib.Path.cwd()
PosixPath('/home/gahjelle/Dropbox/programmering/realpython')

>>> import pyplugs
>>> pyplugs.register(pathlib.Path.cwd)
<bound method Path.cwd of <class 'pathlib.Path'>>
>>> pyplugs.call(package="", plugin="pathlib", func="cwd")
PosixPath('/home/gahjelle/Dropbox/programmering/realpython')

>>> pyplugs._plugins._PLUGINS
{'': {'pathlib': {'cwd': PluginInfo(package_name='', plugin_name='pathlib', func_name='cwd', func=<bound method Path.cwd of <class 'pathlib.Path'>>, description='Return a new path pointing to the current working directory\n        (as returned by os.getcwd()).\n        ', doc='', module_doc='', sort_value=0, label=None)}}}

Another example:

>>> from urllib import request
>>> request.urlopen("https://google.com/")
<http.client.HTTPResponse object at 0x7f7de62650d0>

>>> import pyplugs
>>> pyplugs.register(request.urlopen)
<function urlopen at 0x7f7dedb1c4c0>
>>> pyplugs.call(package="urllib", plugin="request", func="urlopen", url="https://google.com")
<http.client.HTTPResponse object at 0x7f7de6bf2490>

If you leave out func, it will still pick the first function that has been registered inside the module (= plugin):

>>> pyplugs.call(package="urllib", plugin="request", url="https://google.com")
<http.client.HTTPResponse object at 0x7f7de6877280>

Does this work in your usecase?
