Sweet!!! That's about what I was expecting. Thanks!!

Two things (more curiosity than anything):
-> How long did the first version take to compile for you? On my box (Linux 550MHz P-III) DMD ran for ~ 70 sec.

-> What did you use for a convention table? I want to pout that in the doc comments.


A fixed version (inch, cal and hp corrected) of the lib will be up in a few minutes.

ca. 29 sec (with some backround activity)

what kind of system?

Crumbs!

That's where I got the _new_ valuse for the convertions from. Now I have to find a new scource.

A new version of the units lib is up at

http://www.webpages.uidaho.edu/~shro8822/unit.d

Several other libs are also up at:

http://www.webpages.uidaho.edu/~shro8822/point_math.d
http://www.webpages.uidaho.edu/~shro8822/point_lib.d

I would like to submit them all for inclusion in Phobos

While I was writing the unittest I recognized that the most likely error is an error in the convention table (something that can't be checked by the person who wrote that part). Therefor, Would someone please (without looking at my table of conversion factors) finish writing the unittest for the lib?

While I'm sure your units code will be great as part of phobos, I'm actually more interested (surprised rather) in where your file is hosted. I believe we go to school in the same state. :)
I'm in the middle of my second year at Boise State University.

Great, I always wanted to write one! Actually I already have one but it is more like an units interpreter. However, my library has an additional feature, it can take fractional powers of dimensions in p/q form where p and q are integers.

I am interested in adding this feature to your library, its easy. This feature is very useful for engineers, especially mechanical engineers where fractional power of dimensions appear every where. eg. time period of a simple pendulum.

So, do you mind if I take a whack at it ?

One question, why you left out angle and candela from fundamental units ? later one is used a lot in optics.

my units interpreter is at: http://mechsys4.me.udel.edu/home/banala/units.html

its not very userfriendly as of yet, just ported it to D and DWT.

Go ahead, fine by me. I was thinking of adding integer powers my self. One request, I have tried to keep the unit control part as separable as possible so that it would be easy to strip out for performance reasons.

Each fundamental unit used adds a int to the struct and adds more overhead to programs using this library. While not quite as handy, angles can be treated as unit-less (IIRC SI does this) and the candela can be treated as power per area (CGS, US and MKS do this).

This whole lib is rely a bit of a kluge because most of the time units can be determined statically and should be checked statically. I have plans for a template to do this but it will require implicit template specialization, so that's on hold for now.

I found a while ago that one of the contributers to another (internet wide) project I'm ocationaly involved in works right here in town.
