bitfield 1.0.0

New features

• New bf_analyze() function for exploring encoding trade-offs. Reports Pareto-optimal exponent/significand configurations per bit count, with quality metrics including RMSE, max error, underflow, overflow, and changed values at a given decimal precision. Includes a formatted print() method with summary header, type-specific output, and ready-to-paste bf_map() usage hints.
• Floating-point encode/decode rewritten from string-based to arithmetic computation, improving performance and correctness.
• Expanded validation throughout bf_map() and bf_flag() with more informative error messages.

Improvements

• bf_map() now uses template from the registry instead of requiring explicit length/width parameters.
• Vignettes consolidated into a single “Getting Started” guide covering encoding design, bf_analyze(), custom protocols, and community standards.
• Substantially expanded test suite covering bf_analyze, bf_export, bf_protocol, helpers, and edge cases across all core functions.
• Documentation updates across all exported and internal functions.

Bug fixes

• Fixed bf_decode() flag processing and sign bit handling.
• Fixed bf_export() metadata extraction to use correct field names from registry flags.

bitfield 0.8.0

• introduction of bf_flag() function, where building the flag can be found, which is moved out from bf_map().
• complete overhaul of how information is stored in the registry, now it is vastly more W3C PROV compliant than before.
• new protocol category for encoding categories, which are different from cases because they can be set explicitly.
• the registry now contains also the levels or quantiles of the encoded data.

bitfield 0.7.0

• inclusion of the project() helper function that specifies, similarly to person(), the project metadata.
• remove automatic creation of a registry when calling bf_map() for the sake of more care when users set up a new registry. This should contain author and project metadata.
• instead of storing objects in the environment bf_env, they are now made available in the .GlobalEnv for easy use.

bitfield 0.6.0

• rename various things to get a more coherent and intuitive workflow: bf_test() -> bf_map(), operator -> protocol, bf_internal -> bf_pcl
• new function bf_standards() to interact with github to pull, push or list community standards base on the github personal access token.
• formalise the bitfield operators into a protocol, i.e., a standardised list with a dedicated .validateProtocol() function.

bitfield 0.5.0

• merge all functions into bf_test().
• remove bf_standards() and bf_stds.
• merge the previous test-functions into a structure that is similar to bd_stds, i.e., a list with instructions and documentation for that operation/test (bf_internal), which will be called in bf_test().
• revise determination of encoding with more user-friendly interface. Now, everything is specified in bf_test() with the ... argument; documentation explains everything in much more detail.

bitfield 0.4.0

• include the .rast() function for simple handling of gridded objects.
• unit tests for all functions.
• introduction of a small set of standard encodings in bf_stds and the function bf_standard() to create flags from those.

bitfield 0.3.0

• major revision of the template function body for the bitfield operators
• more options for bitfield operators, such as the possibility to specify an NA-value and the position in the bitfield, and a custom description
• more stringent provenance handling, now provenance is reported as a combination of the Action name and the parameters that are used (following PROV terminology and logic)
• revision of the bf_decode() output reporting, now with a more user-friendly return value
• full documentation and functionality of all functions (except auto determination of floating-point encoding for numeric values)
• document also MD5 checksum for registries

bitfield 0.2.0

• revise various functions
• improve text (readme/vignette)
• change naming of the functions
• correct terminology, the class is not the bitfield but instead an array or registry that contains information about the bitfield. Hence, I renamed it to registry
• use attributes to capture a bitflag description and name

bitfield 0.1.0

• Initial CRAN submission
