Nim wrapper

[konsumer]

Hi,
I love this library. Super-simple and seems to work, well. I made a nim-wrapper here.

Usage looks like this:

import gamepad

proc onGamepadAttached(device: ptr Gamepad_device; context: pointer) =
  var js = device[]
  echo "attached: " & $js.deviceID

proc onGamepadRemoved(device: ptr Gamepad_device; context: pointer) =
  var js = device[]
  echo "removed: " & $js.deviceID

proc onButtonDown (device: ptr Gamepad_device; buttonID: cuint; timestamp: cdouble; context: pointer) =
  var js = device[]
  echo "buttonDown(" & $js.deviceID & "): " & $buttonID

proc onButtonUp (device: ptr Gamepad_device; buttonID: cuint; timestamp: cdouble; context: pointer) =
  var js = device[]
  echo "buttonUp(" & $js.deviceID & "): " & $buttonID

proc onAxisMoved (device: ptr Gamepad_device; axisID: cuint; value: cfloat; lastValue: cfloat; timestamp: cdouble; context: pointer) =
  var js = device[]
  echo "axis(" & $js.deviceID & "): " & $axisID & " : " & $value

const GAMEPAD_POLL_ITERATION_INTERVAL=30
gamepad.deviceAttachFunc(onGamepadAttached)
gamepad.deviceRemoveFunc(onGamepadRemoved)
gamepad.buttonDownFunc(onButtonDown)
gamepad.buttonUpFunc(onButtonUp)
gamepad.axisMoveFunc(onAxisMoved)
gamepad.init()

var iterationsToNextPoll = GAMEPAD_POLL_ITERATION_INTERVAL

# in your loop
while whatever:
  dec iterationsToNextPoll
  if iterationsToNextPoll == 0:
    gamepad.detectDevices()
    iterationsToNextPoll = GAMEPAD_POLL_ITERATION_INTERVAL
  gamepad.processEvents()

You can see an example here.

I could probly wrap things further to deref things, and convert non-nim ints and things, but this works ok for my purposes.

I ended up making this wrapper. Linux and Mac are good, but I could really use some help getting it to build on windows.

when defined(windows):
  {.compile: "src/libstem_gamepad/source/gamepad/Gamepad_windows_dinput.c".}
  {.compile: "src/libstem_gamepad/source/gamepad/Gamepad_windows_mm.c".}
  {.passC: "-DFREEGLUT_STATIC".}
  {.passL: "-lXinput -ldinput8 -ldxguid -l/WbemUuid -lOle32 -lOleAut32".}

I get this:

D:\a\nim-gamepad\nim-gamepad\src\libstem_gamepad\source\gamepad\Gamepad_windows_mm.c:32:9: error: unknown type name 'JOYINFOEX'
   32 |         JOYINFOEX lastState;

  147 |         JOYINFOEX info;
      |         ^~~~~~~~~
      |         CPINFOEX

I am trying to build at the very least in Github action, because I don't have a Windows box to test on, easily.
