Unloading/detaching a function from module

[PierreENOlivier]

Hello, I have started using box and it is so far a fantastic tool!

I am coding my first module but I am running into so troubles.
Because I am still debugging and adding parts the functions, I need to reload/refresh the loaded code of my functions, but box does not seem to do that.

I can unload a module if I loaded the module environment (thus all the functions contained inside my script):

box::use(box/module)
box::unload(module)

However, if I loaded a specific function, there is no way to remove it as it does not appear in the Global environment, and also no way to update the code of the loaded function by reruning the code:

box::use(box/module[this_function])

### Tweak some code inside the function

box::use(box/module[this_function])

Is there a way to detach or at least update "this_function"?

I found the reload function and wrote a little helper function using "search()" and "detach()" to find and detach the exported functions.

Hi Pierre,

I am currently working on an auto-reloading feature which will hopefully make this a lot less effort.

Until then, there’s the function box::purge_cache, which marks all loaded modules as unloaded. Afterwards, rerunning the box::use declaration (so, in your case, box::use(box/module[this_function])) will reload and reattach the function.
