443 :: Unit conversion module.

• ventor3000 (orginal) [2014-05-12T11:28:28+02:00] view original

  In a private project of mine, I need a module that can convert between diffrent units, for example:

  Millimeters to Inches, Meters/Hour to Inches/Second etc..

  I'm on my way inplementing such a nimrod module, heavily inspired by the Convert function from delphi ( see http://www.delphibasics.co.uk/RTL.asp?Name=Convert )

  Would such a module be of intrest to the nimrod standard library? (Or should I save myself the work forking nimrods master?)

  Of course there is interest! However, I think you should simply make it a Babel package. We're trying to slim down the stdlib to ease maintenance.

  Thats a good idea indeed. I've also done a lot of work for an updated/bugfixed wrapper of IUP that could go into a babel package and replace the one in standard standard distibution. I'll let you know when.

  Once static[T] works better you could add support for full blown dimensional analysis (check out http://en.wikipedia.org/wiki/Dimensional_analysis#Mathematical_properties) I think nimrod is one of only a few languages that really support a nice clean implementation of compile-time dimensional analysis (and other bits of linear algebra that are useful at compile time).

  We could actually make that "look how I can use newtypes to keep my units in line" argument a reasonable one!

  Maybe somebody should tell the guys from http://www.yosefk.com/blog/can-your-static-type-system-handle-linear-algebra.html about the linear algebra bit. They seem to be losing their sanity over C++.

  support for full blown dimensional analysis

  That's what I tried to do with my Dimrod module (https://github.com/ClementJnc/dimrod, http://forum.nimrod-lang.org/t/368).

  Compilation is still slow and I need to improve the quality of the code but it works.
