capital Q to completely quit

[bjarthur]

if one descends into a hierarchy of dicts with e.g. S, then q backs out one level. it would be convenient to have a way to back all the way out to the REPL with one keystroke. maybe Q?

[tshort]

Good idea! I see no problem with Q.

Enter quits everything and returns the item you're on. That's normally fine for your use case unless the item returns a particularly hairy output.

i didn't know about Enter! maybe it needs to be added to the help that is printed at the top of the output of eye?

it doesn't seem to work with S though on Dicts. in the example below, the last thing i input is three Enter in a row. it takes me back to the previous display the first two times, and then exists and returns the value of the top-level Dict:

julia> using Eyeball

julia> ^C

julia> using Eyeball, DataStructures

julia> foo=Dict("a"=>Dict("b"=>Dict("c"=>1)))
Dict{String, Dict{String, Dict{String, Int64}}} with 1 entry:
  "a" => Dict("b"=>Dict("c"=>1))

julia> bar = eye(foo)

Hmmm. Looks like S and o are working differently. To make this work for S, something like this logic from o is needed. returnfun controls what is returned. The return true means that the menu exits.

Also, here is a version of Q:

        elseif i == Int('Q')
            returnfun = x -> 0
            menu.chosen = true
            return true
