Problem with step-in

To reproduce:

  1. Clear ~/.julia
  2. Edit ~/.julia/config/startup.jl, so it reads:
try
    @eval using Revise
    # Turn on Revise's file-watching behavior
    Revise.async_steal_repl_backend()
catch
    @warn "Could not load Revise."
end

try
    @eval using Rebugger
    # Activate Rebugger's key bindings
    atreplinit(Rebugger.repl_init)
catch
    @warn "Could not turn on Rebugger key bindings."
end
  1. Launch julia 1.0.0 and execute import Pkg; Pkg.add("Rebugger"), then exit
  2. Launch julia again, and execute Rebugger.add_keybindings(stepin="\e[17~", stacktrace="\e[18~")
  3. Type show([1, 2, 4]), put cursor on the beginning of this string and press F6.

Whatever you pressed mapped to stacktrace rather than stepin.

Yes... how silly of me. I am really sorry for taking so much of your time. Perhaps I can contribute back to the manual if you do not mind?

That would be divine! To err is human, and so a good manual tries to anticipate all the ways in which one can be human 😄 Rebugger's manual isn't there yet!
