I cannot figure out how to read from standard input (erlang shell) when starting a module's function from erlang shell. Joe Armstrong's book mentions it in Chapter 13 when explaining io:read(ioDevice,Prompt). But there is no example how it actually works. Any hints? Thanks.

Have you tried (from the io manual page)

Code:

get_chars([IoDevice,] Prompt, Count) -> string() | eof
get_line([IoDevice,] Prompt) -> string() | eof


eg:

Code:
2> X = io:get_line('>').
>FooBar
"FooBar\n"
3> X.
"FooBar\n"


Hope this helps,
Francesco
