No description provided.

Adding BaseUnits class. Adding SI unit system.

angularsen

Some minor things.

+ {
+ if(length == LengthUnit.Undefined)
+ throw new ArgumentException("The given length unit is undefined.", nameof(length));
+ else if(mass == MassUnit.Undefined)


No need to else when throwing.

Add IEquatable and IEquatable<BaseUnits>?

angularsen · 2018-10-15T20:00:48Z

+ /// <returns>True if equal.</returns>
+ public static bool operator ==(BaseUnits left, BaseUnits right)
+ {
+ return left?.Equals(right) == true;


This fails to compare two null values I think.
https://stackoverflow.com/a/73732/134761

Left hand side null is handled by return left?. The right hand side check is handled in the Equals method:
publicoverrideboolEquals(objectobj){if(objisnull||!(objisBaseUnits))returnfalse;

I will add a test 😃

object left = null; object right = null; (left?.Equals(right) == true).Dump(); // False in linqpad

That would not call BaseUnits.Equals, even if cast to null.
(BaseUnits)null==(BaseUnits)null// Does not call BaseUnits == operator

I take that back. Forgot you can't step in.
I'll fix!

Implementing IEquatable<BaseUnits> on BaseUnits, and adding some tests for BaseUnits. Adding some doc too.

…th quantity for example has a BaseUnits where only Length would be set. Only a UnitSystem needs it all. Moving logic there. Expanding UnitSystem tests and logic. Fixing WRC.

Fix for equality operator when both left and right are null

Better add test for != too, in case someone changes the != implementation

angularsen

Good stuff, just some comments.

angularsen · 2018-10-16T17:33:20Z

+ var baseUnits2 = new BaseUnits(LengthUnit.Meter, MassUnit.Kilogram, DurationUnit.Second,
+ ElectricCurrentUnit.Ampere, TemperatureUnit.Kelvin, AmountOfSubstanceUnit.Mole, LuminousIntensityUnit.Candela);
+
+ var baseUnits3 = new BaseUnits(LengthUnit.Foot, MassUnit.Pound, DurationUnit.Second,


No biggie, but I had to scan a bit to see what was different in these three. Could rename the variables to help read that. And you construct these three instance many times so we could have helpers like CreateDerivedUnitA() and CreateDerivedUnitB().

angularsen · 2018-10-16T19:21:58Z

 LuminousIntensity = luminousIntensity;
 }

+ public bool IsBase()


IsBaseUnit and IsDerivedUnit maybe? I had to think a bit when reading usages to get exactly what IsBase meant.

angularsen · 2018-10-16T19:22:08Z

 LuminousIntensity = luminousIntensity;
 }

+ public bool IsBase()


Add xmldoc to public members, that also helps with above comment.

Adding doc. Making tests cleaner. Small method name changes,

# 4.0.0 Release This PR will serve as the list of items to complete and it will be updated to show the progress before finally merged into `master` when completed. We all have busy schedules, so **if you want to help move this work forward then that is much appreciated!** ## The main theme is to reduce binary size In two years it has grown from 280 kB to 1.4 MB and a lot of it is due to unnecessary syntactic sugar with many method overloads for various number types and nullable types - for every of our 800+ units! It simply adds up to a big total. These items are chosen from #180, trying to include as many of the low hanging fruits as possible, while still keeping the list short and realistic to complete in a reasonably short time - we are all busy in our daily lives. We can always have more major version bumps later than trying to perfect it all now. ## Feature complete before November, merged before mid-December I would like to aim for a "beta" pre-release nuget sometime in October with all the items completed, so we can have some time to test it before releasing the final, stable 4.0.0 version before Christmas holidays. We should have the work items list more or less final before Monday, October 8th. ## Changes #### Added - [x] UnitSystem with a different meaning, now defines the base units for a unit system (#524) #### Removed - [x] Replace netstandard1.0 target with netstandard2.0, to avoid the extra dependencies (#477) - [x] Remove code marked as `[Obsolete]`, such as `VolumeUnit.Teaspoon` (#490) - [x] Remove nullable `From` factory methods (#483) - [x] Remove extension methods on _nullable_ number types (#483) - [x] Remove all number extension methods (#497) - [x] Remove `Length2d`, replaced by `Area` (#501) - [x] Remove static methods on `UnitSystem`, should use `UnitSystem.Default` instead (#496) - [x] Remove unit parameter from `ToString()` methods (#546) #### Changed - [x] Throw exception on NaN values in static constructor methods, like `FromMeters()` (#502, see #176 (comment)) - [x] Throw if unit was not specified when constructing quantities, (#499 - #389 (comment)) - [x] Stricter parsing (#343 and #180 (comment)) - [x] Remove unit parameter from `ToString()` methods (#546) - [x] Change Temperature arithmetic back to use base unit Kelvin (#550, see #518) #### Renamed - [x] Correct SingularName for some Flow unit definitions (#494, see #360) - [x] Split/rename UnitSystem into UnitParser, GlobalConfiguration, UnitAbbreviationsCache (#511) #### Fixed - [x] Search for any TODO comments in the code to address, remove comment and either fix or create issue (5d24432) - [x] Update README with v4 changes #498 - [x] Do not try/catch in UnitConverter.Try-methods (#506) - [x] Do not try/catch in `Length.TryParse()` and for other quantities (#507) - [x] Add/update changelog in wiki for v4 with some summary copied from this issue, some v3 to v4 migration instructions and briefly explain why some stuff were removed ## Milestones - [x] Finalize work items list (Monday, October 8) - [x] Release 4.0.0-beta1, feature complete (Wednesday, October 31) - [ ] ~Show release notes and upgrade guide when upgrading to 4.x nuget, if possible~ - [x] Release 4.0.0 (Monday, December 17)
