This article mainly introduces "what are the ways to enable stevedore". In the daily operation, I believe many people have doubts about the ways to enable stevedore. The editor consulted all kinds of materials and sorted out simple and easy-to-use methods of operation. I hope it will be helpful for you to answer the doubts about "what are the ways to enable stevedore?" Next, please follow the editor to study!

The entry point registry maintained by setuptools lists the available plug-ins, but does not provide a way for end users to use or enable them. The common schema for managing the extension set to be used is described below.

Enable by installation

For many applications, simply installing an extension is enough to indicate that the extension should be used. The user does not need an explicit configuration to discover or enable the extension because its entry point can load all discovered plug-ins at run time.

Examples of installation include:

Python-openstackclient

Virtualenvwrapper

Explicitly enable

In other cases, extensions may be installed system-wide, but should not be enabled for a given application or application instance. In these cases, people who deploy or use the application will want to choose which plug-ins to use through explicit configuration steps.

An example of a plug-in enabled through configuration:

Django apps

Sphinx extensions

Trac Plugins

Stevedore.named.NamedExtensionManager

Self-enabling

Finally, some applications ask whether their plug-ins should be enabled. The plug-in looks at other libraries installed on the system, checks external settings, or checks a resource to see if it can be managed by the plug-in. These checks are usually at run time, either when the extension is loaded, or when the user tries to access a particular resource.

Examples of self-enabling:

Anydbm

PIL

Stevedore.enabled.EnabledExtensionManager
