Description
When importing plug-ins in the style of
click-plugin
(command decorator, so plug-ins are loaded during the loading of the top-level command itself), plug-ins may not import fromvpype_cli
(since it isn't fully loaded). To address that, since 1.9, loading plug-ins is deferred to whencli
is actually executed. As a result, the Click's default behaviour for handling--help
(i.e. print and exit before even executingcli
) is unable to list the plug-ins. This PR addresses this by manually handling the top-level--help
parameter (after plug-ins are loaded).Fixes #432
