Hi Eric, In a previous project, I chose vty over ncurses: - you can write your own event loop, and hence handle different event sources. - more liberal license (BSD3 versus GPL) Tim On 26/01/13 19:24, Erik de Castro Lopo wrote:
Hi all,
I am in the process of writing a Haskell program consisting of two threads, one for performing a calculation and one for an Ncurses UI (haskell-ncurses).
The calculation thread needs to feed a stream of numbers back to the UI thread (about 1 value per second) and the UI needs to take input from the user and will pass parameter changes to the calculation thread using an IORef and atomicModifyIORef.
However, I'm not sure how to hande the UI thread. The UI thread would normally wait for Ncurses input using getEvent, but I need advice on how to the the data from the calculation thread.
Any advice or things to try?
Cheers, Erik
