I have put together a runtime unit type library. 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? It shouldn't be hard, just get the file and a units conversion table and add some more lines like those around line 644. here it is: http://www.webpages.uidaho.edu/~shro8822/unit_.d ps: I am submitting this for inclusion in Phobos.

Fahrenheit has an offset so... I didn't put in units like PSI that are named by there definition. I put in all of the units that my table had that looked useful (who besides the GB DMV needs stones?) More units can be added later. non metric units are US (I think). ver 2 fothcoming, several things will change a bit.

WOW!! Thanks! That is impressive. If I may ask, how did you make that? Some
sort
of script I assume? I ask because the Phobos source en-total is 1MB and 647k is
kinda large. Can you think of any way to cut down the code size using a data
table of some kind?
e.g.
enum Types {Foot, Inch, Pound, ...)
real[Types.max][Types.max] test_values;
test_values[Types.Foot][Types.Foot] = 1; // real value is convrtion
test_values[Types.Foot][Types.Inch] = 12;
test_values[Types.Foot][Types.Pound] = real.nan; //nan on no convertion
...
Unit u;
real v;
foreach(int from, real[] ra; test_values)
foreach(int to, real r; test_values)
{
switch(from)
{
case Type.Foot: u = Foot(1); break;
case Type.Inch: u = Inch(1); break;
case Type.Pound: u = Pound(1); break;
...
}
try
switch(from)
{
case Type.Foot: v = u.Foot(); break;
case Type.Inch: v = u.Inch(); break;
case Type.Pound: v =u.Pound(); break;
...
}
catch (ExceptionUnitMisMatch)
{
assert(isnan(r));
continue;
}
assert(!isnan(r));
}

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.

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.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.
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).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. Sai
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.In article <dto5k2$10iq$1 digitaldaemon.com>, BCS says...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

http://www.gnu.org/software/units/units.html Above tool seem to have a pretty good collection of units. It would be nice if the 'runtime unit lib' in discussion can generate arbitrary fundamental units and user defined conversions at runtime (like currency, steradian, bit, music_note etc). Sai

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. Chris
