RcppTOML 0.2.1 on CRAN: Small Build Fix for Some Arches

Two weeks after the release of RcppTOML 0.2.0 and the switch to toml++, we have a quick bugfix release 0.2.1.

TOML is a file format that is most suitable for configurations, as it is meant to be edited by humans but read by computers. It emphasizes strong readability for humans while at the same time supporting strong typing as well as immediate and clear error reports. On small typos you get parse errors, rather than silently corrupted garbage. Much preferable to any and all of XML, JSON or YAML – though sadly these may be too ubiquitous now. TOML is frequently being used with the projects such as the Hugo static blog compiler, or the Cargo system of Crates (aka “packages”) for the Rust language.

Some architectures, aarch64 included, got confused over ‘float16’ which is of course a tiny two-byte type nobody should need. After consulting with Mark we concluded to (at least for now) simply override this excluding the use of ‘float16’.

The short summary of changes follows.

Changes in version 0.2.1 (2023-01-25)

  • Explicitly set -DTOML_ENABLE_FLOAT16=0 to permit compilation on some architectures stumbling of the type.

Courtesy of my CRANberries, there is a diffstat report for this release. More information is on the RcppTOML page page. Please use the GitHub issue tracker for issues and bugreports.
