9925 :: How to declare array (of unknown size) of floats for a webaudio wrapper function signature?

• yalexr (orginal) [2023-02-22T02:12:23+01:00] view original

  I am adding some AudioParam method support to nim-webaudio .

  So far so good and tested until this:

  setValueCurveAtTime(values, startTime, duration), where values is an array of floating-point numbers.

  How would I declare such an array (of undetermined size)?

  proc setValueCurveAtTime*(param: AudioParam, values:???, startTime: float, duration: float) {.importjs:"#.setValueCurveAtTime(@,@,@,@)".}

  I'm -- on a roll :) and -- guessing values: openArray[float] .

  proc setValueCurveAtTime*(param: AudioParam; values: openArray[float]; startTime, duration: float) {.importjs:"#.$1(#, #, #, #)".}

  Run

  Thanks !

  I didn't know of that alternate way to express repeated types. I'll have to see if I can find a guide to writing js wrappers in nim.

  Thanks again.
