"Professional CMake" book suggest the following:
"Targets should build successfully with or without compiler support for precompiled headers. It
should be considered an optimization, not a requirement. In particular, do not explicitly include a
precompile header (e.g. stdafx.h) in the source code, let CMake force-include an automatically
generated precompile header on the compiler command line instead. This is more portable across
the major compilers and is likely to be easier to maintain. It will also avoid warnings being
generated from certain code checking tools like iwyu (include what you use)."
Therefore, removed the "#include <PreCompiled.h>" from sources, also
there is no need for the "#ifdef _PreComp_" anymore
Defaults for both precision (number of digits after decimal point)
and denominator (number of fractions) are defined on various places
making difficult to find which default is used for various tasks.
Store these values at one central place: UnitsApi. Unless overriden
by user, default values are defined by unitSchemasDataPack.
Fixes: Maintaining schemas is difficult and error-prone
- Facilitate easy schemas add, remove, change, etc.
- Remove 14 files containing approx 2,190 lines of if/else code and data
- Place data in one file (UnitsSchemasData.h) using a normalized structure (including special functions)
- Isolate and simplify data operations (code)
- Remove schemas enum to keep data independent of code
- Separate responsibilities: Specifications, data, schemas, schema
- Add schema data 'isDefault'
- Add schema data name
- Prefer algorithms to raw loops
- Add schemas unit tests
- Tweak quantity unit tests
Affect strings presented to the user on the combobox to select unit system.
- The symbol to represent angles on "degree" unit is '°'
- Change imperial velocity to "ft/s" to enforce the use of 's' symnbol as second
- we must read out the unit system description UTF8 to get the characters ² and ³
- update unit system description according to today's unit "cft" addition
- don't hardcode the unit system descriptions in the .ui file
- add acceleration to imperial schema
