Leksah 0.15.0.1, GHC 7.10.1 : Is it possible to pass user input to a Haskell program which is launched inside Leksah Haskell IDE? If yes, how?

Question :

Is it possible to run a program in Leksah and enter user input ? If yes, how ?

Reason for asking:

I tried two different ways to run a program in Leksah and enter user input and both ways failed:

First approach - running in normal mode (not GHCi) :

Simply writing to console works fine :

However, Leksah hangs when I try to run the following program, asking for input :

Second approach : using GHCi in Leksah.

Evaluating main2 works fine. Evaluating main hangs. It is not possible to enter input.

Any idea how one can enter user input when launching a program in Leksah ?

Solution

I am afraid little has changed since the last time this came up. You can now make a GHCJS app and run it in the Out pane. It can include DOM input elements and handle DOM events. StdIn input is still unsupported.
