Development version 9002 pre-release

This is the first development version of package blueprint. It packs a lot of features. The intent is to provide fundamental building blocks for future releases. Taken straight from NEWS.md, here are the relevant changes.

• New concepts

  • strict atomic types
    • Strict atomic are R types considered to be atomic objects in
      the package: NULL, logical, integer, single (yes, single, see
      documentation of the package for more information), double, complex,
      character and raw vectors.
    • These are the fundamental building blocks of R.

• New classes

  • Atomic
    • A class to hold blueprints of strict atomic vectors. This is an
      important class packed with a lot of features. Just like strict atomic
      vectors are the building blocks of R, so is class Atomic for the
      package. All other blueprint's classes will reuse this class.

• New features

  • A new %bp% operator which can be used to construct blueprints in a
    concise way. We call it the Blueprinter.
  • New assertion functions: is_single(), is_strict_atomic(),
    is_named_vctr() and is_named_list(). These are very useful.

• Important changes

  • Significant changes to class Blueprint to ensure consistency with class
    Atomic.
  • Package now imports packages jsonlite and yaml for I/O.

• Other important changes

  • Hundreds of new unit tests. We now use a consistent test structure derived
    from testthat 3e edition.
  • New internal mechanisms / utility functions. They are more robust and
    better tested.
  • New options system for I/O with packages jsonlite and yaml.
  • New (experimental) Github workflows for future CI/CD pipeline.
