###
A basic custom logging implementation. The idea is to (extremely) verbosely
log every received resource.
###
casper = require("casper").create
    verbose: true       # we want to see the log printed out to the console
    logLevel: "verbose" # of course we want to see logs to our new level :)

###
Every time a resource is received, a new log entry is added to the stack
at the 'verbose' level.
###
casper.on 'resource.received', (resource) ->
    infos = []
    props = [
        "url"
        "status"
        "statusText"
        "redirectURL"
        "bodySize"
    ]
    infos.push resource[prop] for prop in props
    infos.push "[#{header.name}: #{header.value}]" for header in resource.headers
    @log infos.join(", "), "verbose"

# add a new 'verbose' logging level at the lowest priority
casper.logLevels = ["verbose"].concat casper.logLevels

# test our new logger with google
casper.start("http://www.google.com/").run ->
    @exit()
