Changelog

2.5.4

  • Introduced CMake Workflow Presets

2.5.3

  • Adjusted CMake to only look for Catch2 if tests are being built. Reduces warnings for projects which use something else (e.g. GTest)
  • Change building instructions to work with conan 2.0 CMakeDeps generator - This sets the minimum CMake version to 3.23
  • Remove conan recipe as it is maintained in the conan center index

2.5.2

  • Add angular_frequency_t as type
  • Add operators to convert velocity to frequency and vice versa (i.e. velocity / length = frequency)
  • Add CodeQL analysis to CI pipeline

2.5.1

  • Bugfix: unit.as<other_unit>() automatically infers the underlying type if not explicitely specified.
  • Using Catch2 test discovery in CMake

2.5.0

  • Removed implicit conversion from primitives to unit_t. See issue #106 for details
  • When converting units to string a space is inserted between the value and the unit, as described in the SI brochure, section 5.4.2

    • The numerical value always precedes the unit and a space is always used to separate the unit from the number

  • Fix various spelling errors (thanks to melg8).
  • Renamed sterradiant_t to steradian_t which is correct

2.4.1

  • Fix reported issue that operator/(scalar / unit) would calculate the ratio into the value.
  • Add function as<unit_t>() to unit for convenient conversion to a unit of the same type but different ratio

2.4.0

  • Add surface flow and volumetric flow units

2.3.0

  • Add string conversions for velocity (m/s) and acceleration types (m/s^2)

2.2.0

  • Add degree_t to angle type including literals _deg

2.1.3

  • Fix CI pipeline for windows
  • Add missing conversion between float and double for operator/

2.1.2

  • Update to catch 2.13.6 in the conan recipes
  • Remove deployment to bintray.com as it is scheduled to sunset on May 1 2021

2.1.1

  • Tests are built without the need for conan if catch2 is found. (using conan is still the preferred way)
  • Cleaning up obsolete todos and typos

2.1.0

  • Moved helper function such as unit_cast and unit_with_common_ratio to own file for easier maintenance
  • Moved cross-unit-operations and epsEqual to a separate file for easier maintenance
  • Rename epsEqual() to eps_equals() for consistency with naming scheme

2.0.4

  • Add literals for ton types up to peta ton

2.0.3

  • Add synonymous *_ton_t types for mass magnitudes
  • Renamed default branch from master to main

2.0.2

  • Documentation update and fixing typos in test names
  • Full magnitudes for mass up to zetta_gram

2.0.1

  • Refactored type dependent functions to use std::enable_if_v instead of std::enable_if::value
  • Use value types for type traits (i.e. std::is_arithmetic_v instead of std::is_arithmetic::value
  • Add SI::detail::is_ratio_v and SI::detail::is_unit_t_v

2.0.0

  • Support for fractions as exponents (Types from version 1.x.x are no longer supported)
  • Rename access to stored scalar values to value() (from previously raw_value()) (Brakes interfaces from 1.x.x)
  • The conan-package is named si instead of SI to match the conan naming convention (Include-paths stay upper case)

1.7.6

  • Refactoring conanfile.py to create cmake object only once for a tiny bit more performance when packing

1.7.5

  • conanfile.py pulls the version out of CMakeLists.txt for packaging.
  • Selecting the cmake option SI_INSTALL_LIBRARY=OFF removes the target install completely
  • Add new-line to the end of all files to fit with the ConanCenter code convention.

1.7.4

  • If SI is built from within conan the conanbuildinfo provided by conan will be used instead of getting it from github
  • Cleanup of obsolete code

1.7.3

  • Extended technical documentation
  • Add speed of light to velocity

1.7.2

  • Correct naming for angle types radian_t (was radiant_t)
  • Separate test for version consistency from installation tests

1.7.1

  • Changed exponent type to int8_t as char might be unsigned
  • Documentation and tests are only built if built as top-level project

1.7.0

  • Add literals and typedefs for km/h (_km_p_h) m/s (m_p_s)
  • Add literals for astronomical units of length (AU), light-years (ly) and parsecs (pc)
  • API documentation is built over the cmake-target api_doc

1.6.1

  • Add operators ++ and -- for units
  • Add cmake option SI_ENABLE_TESTING (default ON) to selectively disable tests for SI if used with add_subdirectory() and EXCLUDE_FROM_ALL

1.6.0

  • Implicit type conversion for units (i.e. between units with internal double and float representation)
  • Turn installation of by setting the cmake option SI_INSTALL_LIBRARY to OFF (default is ON). (Thanks to bladan for bringing it up.)
  • Acceleration is buildable from v^2 / L (velocity squared divided by length). (Thanks to bladan for the work)

1.5.1

  • Added SI::to_string() function to avoid using streams
  • Update to Catch2 v2.11.1 for testing

1.5.0

  • Bugfix: Operators < and > where comparing the wrong way round (this is embarrassing)
  • Added Operators <= and =>
  • Installation tests for OSX and Windows
  • Renamed SI/detail/string.h to unit_symbol.h because of resolution-problems in osx/xcode

1.4.1

  • Added micro-benchmarks for operations on unit_t
  • Pulling catch2 for testing with conan is only done if testing is enabled
  • Removed defaults for template parameters for == and !=

1.4.0

  • Rule of five: assignment and construction for units with different ratios
  • Retrieving Catch2 with conan to avoid having it in the repo (This no effect on using SI)

1.3.1

  • Overall linting

  • Added momentum (Thanks to Kicer96)
  • Added packaging information for conan.io and deployment to bintray

1.2.0

  • added SI_ prefix to preprocessor flag to disable ratio conversion to SI_DISABLE_IMPLICIT_RATIO_CONVERSION to scope it closer
