actually, I think the way to go is similar to your enscripten demo. jhs, btw, has 1!:2&4 and 1!:2&5 output to the console window, but j7 jgtk does not.
jhs also has multiple windows connect to the same process (variables declared in one window are available in the other), but 1!:2&2 prints to the window it was called from. Another application is customized CLI interfaces (inspired again by your demo) where the user can do anything, but commands can be taken from pulldowns or listboxes. Restricting to noun producing expressions lets you use ". for evaluation, and likely is sufficient for anticipated applications. 0!:111 is interesting in that it displays results without returning them, and probably displays them to screen. ----- Original Message ----- From: Joe Bogner <[email protected]> To: [email protected] Cc: Sent: Wednesday, November 26, 2014 3:23 PM Subject: Re: [Jgeneral] a way to attach another console to J process That makes sense. I can see the usefulness of it as well. It looks like you could potentially redirect stdout through a dll[1] (windows) and some other mechanism on linux Do you need to call 1!:2&4 ? Instead, could append to a global noun and then periodically refresh a display of that noun? It seems like each window could run 0!:100 on it's input and then have it's own log of the commands that were entered [1] - http://stackoverflow.com/questions/573724/how-can-i-redirect-stdout-to-some-visible-display-in-a-windows-application On Wed, Nov 26, 2014 at 2:30 PM, 'Pascal Jasmin' via General < [email protected]> wrote: > There would be a single J process.
