How to test if result of a command contains a string in fish shell?

fish, osx-mountain-lion, terminal

Solution

So I ended up fixing this with the following:

# Toggle lights
function lights --description "Toggle Wemo Lights"
    set -l wemo (wemo status)
    switch $wemo
        case '*1'
            wemo switch "Lights" off
        case '*0'
            wemo switch "Lights" on
    end
end

Problem

I'm trying to write a brief function to allow me to toggle wemo lights on and off from the command line. Basically I have a command that if i type `wemo status` will return either `Switch: Lights 1` if the lights are on or 0 if they are off. I'd like to write a fish function that essentially lets me toggle them: ``` function lights --description 'Toggle lights' if contains (wemo status) "Lights 1" wemo switch "Lights" off else wemo switch "Lights" on end end ``` Though this doesn't work. I'm thinking that the parens probably do a textual replacement? Anyone know how I can test if a string contains another string in Fish?
