Hello all,
I've written a little Haskell program to get information from a MySQL database (great thanks to anybody reading this who works on HSQL, by the way) but I want to keep the user's password concealed, obviously. Currently I prompt for it from the terminal, but the problem is that it's echoed just like all other input. I would like to disable input echo when asking for the password, but I'm not sure how. I notice there's a System.POSIX.Terminal module, but I have no idea how to use it, or whether it will do what I want. Any ideas would be greatly appreciated.
Best regards.
In C you usually use: getpasswd (http://docsrv.sco.com:507/en/man/html.S/getpasswd.S.html) I cannot find it System.Posix, so you might have to write your own FFI bindings. Otherwise, you can play around with the terminal modes from: http://haskell.org/ghc/docs/latest/html/libraries/unix-2.2.0.0/System-Posix-... Good luck!
