A custom Julia REPL mode that memes back at you in spongebob spek whatever you say.

spongespek.jl

using ReplMaker

function spongespek(phrase::String)
        casecounter = 0
        spek = ""
        for letter in phrase
                casecounter += 1
                if casecounter % 2 == 1
                        spek *= uppercase(letter)
                else
                        spek *= lowercase(letter)
                end
        end
        println(spek)
end

initrepl(
        spongespek, 
        prompt_text="sponge> ",
        prompt_color = :yellow, 
        start_key=')', 
        mode_name="sponge_mode"
)

This is a great example of how to use ReplMaker!

if you add:
valid_input_checker=complete_julia
it'll work great for JuliaTutor :D
