|
A Plugin consists of a list of Hooks, applied to django.conf.settings when AppConfig.read() -> Plugin.register() is called.
|
|
Plugin.register() then calls each Hook.register() on the provided settings.
|
|
each Hook.regsiter() function (ideally pure) takes a django.conf.settings as input and returns a new one back.
|
|
or
|
|
it modifies django.conf.settings in-place to add changes corresponding to its HookType.
|
|
e.g. for a HookType.CONFIG, the Hook.register() function places the hook in settings.CONFIG (and settings.HOOKS)
|
|
An example of an impure Hook would be a CHECK that modifies settings but also calls django.core.checks.register(check).
|
|
In practice any object that subclasses BaseHook and provides a .register() function can behave as a Hook.

Both core ArchiveBox code and plugin code depend on python >= 3.10 and django >= 5.0 w/ sqlite and a filesystem.
|
|
Core ArchiveBox code can depend only on python and the pip libraries it ships with, and can never depend on plugin code / node / other binaries.
|
|
Plugin code can depend on archivebox core, other django apps, other pip libraries, and other plugins.
|
|
Plugins can provide BinProviders + Binaries which can depend on arbitrary other binaries / package managers like curl / wget / yt-dlp / etc.
|
|
|
|
The execution interface between plugins is simply calling builtinplugins.npm.... functions directly, django handles
|
|
importing all plugin code. There is no need to manually register methods/classes, only register to call
|
|
impure setup functions or provide runtime state.
|
|
settings.CONFIGS / settings.BINPROVIDERS / settings.BINARIES /... etc. are reserved for dynamic runtime state only.
|
|
This state is exposed to the broader system in a flat namespace, e.g. CONFIG.IS_DOCKER=True, or BINARIES = [
|
|
..., Binary('node', abspath='/usr/local/bin/node', version='22.2.0'), ...
