Question

This is my code for livescript:

                        if (res = json.msg.match /^iSearchup\s(.*)$/i)? then
                            getReq("[url='http://urbanscraper.herokuapp.com/define/'][http://urbanscraper.herokuapp.com/define/[/url]" + encodeURIComponent(msg.splice(1, msg.length - 1).join(" ")) + ".json", function(res, passback)
                            if (res.word && res.definition){
                                @socket.send JSON.stringify {
                                    type: \pmsg
                                    nick: 'iPoddy:'
                                    msg: json.from + ": " + res.word + " - " + res.definition
                                }
                            }
                            else {
                                @socket.send JSON.stringify {
                                    type: \pmsg
                                    nick: 'iPoddy:'
                                    msg: json.from + ":  Sorry, no results were returned."
                                }
                            }

That is my code. It gave me the error "dedent" but I fixed it and it still give me that error again. Help?

You have several errors in this code. It will give you an error of UNEXPECTED DEDENT because you are mixing spaces and tabs and LiveScript is a whitespace-strict programming language. So on, avoid the use of brackets while using LiveScript. Remember also that in a conditional structure, like if, you might use then after. This will not compile due to:

Mixing spaces and tabs
else keyword with brackets
Expecting then after expression to determine condition
Syntax Error in function(res, passback)

And you have some little issues and not standardized practices:

Using assignment operator = instead of ==|~= for comparasion
Using an invalid lambda expression as a parameters in function(res, passback)
Using + to concat, instead of ++
Using && operator, instead of and
Using parentheses to encapsulate a single expression in the first conditional

This should work well:

if res ~= json.msg.match /^iSearchup\s(.*)$/i then
    url = "[url='http://urbanscraper.herokuapp.com/define/'][http://urbanscraper.herokuapp.com/define/[/url]"
    getReq <| url ++ encodeURIComponent(msg.splice(1 msg.length - 1).join(" ")) ++ ".json"
    if res.word && res.definition then
        @socket.send <| JSON.stringify(
            type: \pmsg
            nick: 'iPoddy:'
            msg: json.from ++ ": " ++ res.word ++ " - " ++ res.definition
        )
    else
        @socket.send <| JSON.stringify (
            type: \pmsg
            nick: 'iPoddy:'
        msg: json.from ++ ":  Sorry, no results were returned."
        )
