Do you need advice on what? I didn't understand your last phrase.
IIUC, it has to do which how to interrupt a blocking call to ncurses event handling, from another thread (the calculation thread) to let the UI thread refresh the UI with something to display (the calculation). I've been confronted with the same problem in the past, and i haven't found a satisfactory solution with ncurses. Erik, I think the only way to do that with ncurses, is to wrap the ncurses getevent with a select loop on the terminal fd and an arbitrary fd to be able to "ping" the select loop for arbitrary processing. You can also replace the arbitrary fd with a SIGALARM to yourself which i believe would interrupt select too. I don't think there's any solution that integrate nicely with the haskell way, but i'ld be happy to be wrong on this. In my case, i switched to Vty which solved this problem, by allowing to send arbitrary strongly-typed event to widgets. -- Vincent
