**Full Changelog**: https://github.com/ken-morel/comberload/commits/v1.0.0
I have recently built some little command line utility. It simply
receives a command, parses the command and evaluates it with syntax coloring
and autocompletion from [prompt_toolkit](https://pypi.org/project/prompt_toolkit).
But there was an issue, prompt_toolkit loaded **extremely**, I was wasting alot
time to load a package which was not indispensable to my app.
comberload permits you to register modules for queued loading and callbacks
if they are not loaded yet, howaworks?
a simple example for a function which uses prompt_toolkit.prompt but can
fallback to simple input
python
import comberload
comberload("prompt_toolkit")
def get_input():
import prompt_toolkit
return prompt_toolkit.prompt()
get_input.fallback
def fallback_get_input():
return input()
get_input() immediately uses fallback
get_input() abit later, uses prompt_toolkit
comberload uses a worker function running on a seperate thread to load the
modules as listed in the queue. Each time you call on `comberload("module1", "module2")`
the modules are queued and loaded.
multiple fallbacks
You can easily queue fallbacks as:
python
import comberload
comberload("mod1", "mod2")
def first():
pass
first.fallback
comberload("mod3")
def second():
pass
second.fallback
def third():
pass
callbacks
comberload also permits you to register callbacks when some modules finish loading
as
python
import comberload
comberload("mod", "mod2").fallback
def mod_and_mod2_loaded():
pass
best practice
Only what necessary
I will advice to load only what is necessary taking such an approach
Loading in beginning
What I will advice is to queue all the required import at the begining of each
of your modules to permit all of them load without having to fallback.
python
... imports
import comberload
comberload("all", "my", "modules")
... rest of code
Well, you're all set. Listening for issues at https://github.com/ken-morel/comberload ,
till then, good coding!
