Re: [Haskell-cafe] Any recommendations on how to interact with the running state of a program?

Cool, thanks. But the ChangeHandler would still be modifying some mutable state that some other thread is referencing while it's running. That would still be via an IORef? I guess this is a similar problem as having a play/pause/skip controls to a video player. Is the interface between the "running" thread and the user triggered events an IORef? Or is there some other way to wrap that. Thanks, Anatoly On Thu, May 28, 2015 at 6:32 PM Charlie Durham wrote:

Check out the configurator package: https://hackage.haskell.org/package/configurator

It has auto reloading of config files through the aptly named autoReload function. Pretty cool stuff.

How would the program get updated values? via an IORef? This thing is running until the user decides the output looks good

I am playing around with some deep learning algorithms and I need a way to periodically read the intermediate result and change some of the system variables.

Any ideas on how to best approach this problem? I was thinking of something basic, like having the program periodically read and write from some files.

Thanks, Anatoly
