plugins plugin for oclif
This plugin is used to allow users to install plugins into your oclif CLI at runtime. For example, in the Heroku CLI this is used to allow people to install plugins such as the Heroku Kafka plugin:
$ heroku plugins:install heroku-kafka
$ heroku kafkaThis is useful to allow users to create their own plugins to work in your CLI or to allow you to build functionality that users can optionally install.
One particular way this is useful is for building functionality you aren't ready to include in a public repository. Build your plugin separately as a plugin, then include it as a core plugin later into your CLI.
First add the plugin to your project with yarn add @oclif/plugin-plugins, then add it to the package.json of the oclif CLI:
{
"name": "mycli",
"version": "0.0.0",
// ...
"oclif": {
"plugins": ["@oclif/plugin-help", "@oclif/plugin-plugins"]
}
}Now the user can run any of the commands below to manage plugins at runtime.
To make it simpler for users to install plugins, we have "friendly name" functionality. With this, you can run mycli plugins:install myplugin and it will first check if @mynpmorg/plugin-myplugin exists on npm before trying to install myplugin. This is useful if you want to use a generic name that's already taken in npm.
To set this up, simply set the oclif.scope to the name of your npm org. In the example above, this would be mynpmorg.
Note that in the above example, the plugin prefix defaults to plugin. If you're setting the scope, you can also override the plugin prefix using oclif.pluginPrefix.
For example, let's say oclif.scope is set to mynpmorg and oclif.pluginPrefix is set to myprefix. When you run mycli plugins:install myplugin, it will first check if @mynpmorg/myprefix-myplugin exists on npm before trying to install myplugin.
Over time in the Heroku CLI we've changed plugin names, brought plugins into the core of the CLI, or sunset old plugins that no longer function. There is support in this plugin for dealing with these situations.
For renaming plugins, add an alias section to oclif.aliases in package.json:
"aliases": {
"old-name-plugin": "new-name-plugin"
}If a user had old-name-plugin installed, the next time the CLI is updated it will remove old-name-plugin and install new-name-plugin. If a user types mycli plugins:install old-name-plugin it will actually install new-name-plugin instead.
For removing plugins that are no longer needed (either because they're sunset or because they've been moved into core), set the alias to null:
"aliases": {
"old-name-plugin": null
}old-name-plugin will be autoremoved on the next update and will not be able to be installed with mycli plugins:install old-name-plugin.

ARGUMENTS
PATH [default: .] path to plugin
FLAGS
-h, --help Show CLI help.

--[no-]install Install dependencies after linking the plugin.
DESCRIPTION
Links a plugin into the CLI for development.
Installation of a linked plugin will override a user-installed or core plugin.
e.g. If you have a user-installed or core plugin that has a 'hello' command, installing a linked plugin with a 'hello'
command will override the user-installed or core plugin implementation. This is useful for development work.
