I have an addon that computes some settings for another addon. I'd like to be able to warn the user if the target addon isn't installed. How can I safely check if an addon is installed. I've seen the System.HasAddon() call but that doesn;t seem to be available to a Python script (or is it?) - leastways, I have no idea how to call it.

I'm sure it must be possible, but I can't for the life of me work it out.

or try
addon = xbmcaddon.Addon("script.xxx")
It probably either throws an exception when not available or addon becomes None.
Didnt test though.

Code:

def script_chk(script_name):
return xbmc.getCondVisibility('System.HasAddon(%s)' % script_name) == 1

this is what i use, it returns bool

Code:

def script_chk(script_name):
return xbmc.getCondVisibility('System.HasAddon(%s)' % script_name) == 1

this is what i use, it returns bool

you can drop the "== 1" from that expression.
EDIT: oh, didnt know that, according to docs it really returns 1 and 0.
Shouldnt matter for most python coding styles though.

I'd suggest JSON-RPC call for installed Addons as alternative

Thanks to all for the help.
