Units and Quantities of Measurement library for D.

This is a modified version of David Nadlinger's original library for working with units of measurement in D.

Task List

  • Use new alias syntax

  • Use new enum syntax

  • Use new template syntax

  • Use UFCS

  • Use AliasSeq inplace of TypeTuple

  • Use std.meta.Repeat instead of RepeatTypeTuple

  • Qualify unittests with, when possible, @safe pure nothrow @nogc

  • Indentations according to Phobos code-standard

  • Remove need for makeIndexCtfe

  • Move staticFind and IndexedTuple to std.meta

  • Replace Curry with std.functional.applyLeft.

  • Make ScaledUnit with integer precision (such as 10 degrees) work with trigonometric functions in si.d. Currently errors caused by incorrect cast in {Scaled|Affine}Unit.{from|to}Base.

  • Perhaps add LinearUnit and use it to express mappings between, for instance, Celsius and Fahrenheit.

  • Refactor GetConversion to do a breadth-first search instead of current depth-first.

  • Find a way to represent sample rate. Use it to infer FFT-frequencies. Add it either here or to samplerate or sampling.

This alternative implementation contains unit expression parsing which might be of interest aswell: https://github.com/biozic/quantities/issues/2#issuecomment-150809715
