This is a pre-production deployment of Warehouse, however changes made here WILL affect the production instance of PyPI.
Project Description

Reloadr

Python hot code reloading tool.

pip install reloadr

Usage

You can simply decorate your functions / classes with @reloadr and you are ready to go.

from reloadr import reloadr

@reloadr
def do_something(a, b):
    return a + b

@reloadr
class SomeThing:
    def do_stuff(self):
        pass

Then, to reload the code, you can use of the following:

# Manual reload
SomeThing._reload()

# Automatic reload using system (requires library 'watchdog')
SomeThing._start_watch_reload()

# Automatic reload in a thread every 1 second
SomeThing._start_timer_reload(1)

Examples

Launch an example (they each contain an infinite loop), then change the source code of the decorated class or function.

git clone https://github.com/hoh/reloadr.git

python examples/01_manual_reload.py

How it works

Instead of importing your source file again, which can lead to undesired side effects, Reloadr fetches the new code of your function within the Python source file, and executes that code in the environment of your already loaded module.

This allows it to reload code that is followed by blocking instructions such as the infinite loops you can find in the examples.

To achieve this, Reloadr relies on RedBaron , an great tool for manipulating Python source code.

Future plans

This project is still in its early stages. All ideas for improvement are welcome.
