I'm starting a new thread, but for previous reference, see [1].
This patch aims to improve pass's connection with extensions by showing help
from them when pass's help command is issued. It's backwards compatible.
Extension makers could add a help function named like `help_extensionname()`,
which pass looks for and calls during help command execution.
If such function doesn't exists, then it shows "no help available". If there
are no enabled extensions, then "no extensions enabled" is shown. If there are
no extensions at all, then it shows regular help.
This is very usefull for those who love using extensions, and doesn't impact at
all on users who don't use them. It even reminds you of the extensions you have
installed by listing them.
Example with extensions enabled:
Usage:
...
pass version
Show version information.
From extensions:
pass example
This is an example extension.
pass nohelp
(no help available)
More information may be found in the pass(1) man page.
Example without extensions enabled:
Usage:
...
pass version
Show version information.
From extensions:
(no extensions enabled)
More information may be found in the pass(1) man page.
Example without extensions (shows regular help statement):
Usage:
...
pass version
Show version information.
More information may be found in the pass(1) man page.
