<h1 class="title">Module <code>pluginconf.bind</code></h1>
</header>
<section id="section-intro">
<p>Basic plugin loader implementation for flat namespaces. Ties together
pluginconf lookups and config management for plugin loading in apps.
It's rather basic, and subject to change. Does impose a config dict
format, but no storage still.</p>
<h3 id="usage-example">Usage example</h3>
<pre><code># designate a plugins/*.py package as plugin_base
import plugins
import pluginconf.bind
pluginconf.bind.base(plugins)
# preset core app settings / load from json, add plugin options
conf = {
"plugins": {
}
}
pluginconf.bind.defaults(conf)
# load conf-enabled plugins, and register modules somehow
for mod in pluginconf.bind.load_enabled(conf):
mod.init()
</code></pre>
<h3 id="find-by-type">Find by type</h3>
<pre><code>for name, pmd in pluginconf.bind.find(type="effect").items():
mod = pluginconf.bind.load(name)
if pmd.category == "menu":
main_win.add_menu(mod.menu)
</code></pre>
<p>Note that this uses meta data extraction, so should best be confined
for app setup/initialization, not used recurringly. The config state
usage is the preferred method. (Only requires property loading
once, for installation or with <code><a title="pluginconf.gui.window" href="gui.html#pluginconf.gui.window">window()</a></code> usage.)</p>
<hr>
<p>Method interactions: 🚐 = import, 🧩 = meta, 🧾 = config, 🛠
= setup</p>

<p>Module should be a package, as in a directory and init <code>plugins/__init__.py</code>.
Ideally this module was already imported in main. But parameter may be a string.</p>
<p>This could be invoked multiple times for the package name to append further
path= arguments (=./contrib/, =/usr/share/app/extenstions/, or a .pyz). Which
is functionally identical to declaring <code>__path__</code> in the <code>package/__init__.py</code>.</p></div>
