As the new maintainer of the "powermate" package, I'm pleased to announce the first new release in nearly 9 years! This library is for interfacing the Griffin PowerMate USB (a big silver knob you can turn and click) with Haskell on Linux. You can read events from the PowerMate, and control the brightness, pulse speed, and pulse waveform of the built-in blue LED. https://hackage.haskell.org/package/powermate-1.0 https://github.com/ppelleti/powermate Version 1.0 is a major release with some breaking changes. The complete list of changes since version 0.1 is: * Now works with GHC 7.2.2 - 8.0.1. * Added Eq, Ord, Show, and Read instances for Event and Status. * Added example programs powermate-print and powermate-pulse. * Added documentation. * An open PowerMate is now represented by the opaque type 'PowerMate' instead of 'Handle'. A new function 'closeDevice' exists to close the opaque 'PowerMate' type. * Fixed a bug where the PowerMate would get confused and start dropping button presses if you set the LED. * Removed extraneous printing to stdout. * Removed getUSBName and readEventWithSkip; I didn't see the utility in these functions. * readEvent no longer returns a Maybe. There was no meaning to 'Nothing' and it just had to be ignored. * Removed the MPD module. It wasn't directly related to the PowerMate functionality, and the "libmpd" package seems to be an alternative which is more complete and better maintained. --Patrick
