What is constants?

The R package for CODATA constants rebuilt its symbol table on NIST's naming so future updates stop being hand work.

constants exposes the CODATA recommended values of the physical constants to R, as a data frame plus symbol lists that carry units, uncertainties, or both. The package reached 1.0.0 on the 2018 CODATA release and has shipped once since, purely to track a units package update. Its surface is small and its release cadence is bound to CODATA, which revises every few years.

What is hexfont?

A GNU Unifont packager whose real work is making a huge font load fast.

hexfont ships GNU Unifont's hex bitmap files to R as bittermelon font objects, covering the full Unicode range. The last two releases were about load cost and portability: a user-level cache for precompiled fonts, then making that cache read-only by default so nothing is written unless asked. The font data itself tracks Unifont v16.0.02.

The R package for CODATA constants rebuilt its symbol table on NIST's naming so future updates stop being hand work.

◆ Current state

constants exposes the CODATA recommended values of the physical constants to R, as a data frame plus symbol lists that carry units, uncertainties, or both. The package reached 1.0.0 on the 2018 CODATA release and has shipped once since, purely to track a units package update. Its surface is small and its release cadence is bound to CODATA, which revises every few years.

◆ Where it's heading

The direction set at 1.0.0 was to stop being a curated convenience wrapper and become a mechanical mirror of NIST. Hand-crafted symbol names were replaced with NIST's own ASCII symbols, categories adopted NIST's, and uncertainty switched from relative to absolute — all framed by the maintainer as necessary to make future CODATA updates routine. On top of that the package gained a correlation matrix and optional integration with the quantities package, moving it from a lookup table toward something that can propagate uncertainty.

◆ Prediction

Having rebuilt the symbol table specifically so CODATA revisions become mechanical, the next substantive release most likely tracks a new CODATA dataset rather than adding API. The experimental correlated-value support, disabled by default at 1.0.0, is the one part these entries flag as unfinished.

A GNU Unifont packager whose real work is making a huge font load fast.

◆ Current state

hexfont ships GNU Unifont's hex bitmap files to R as bittermelon font objects, covering the full Unicode range. The last two releases were about load cost and portability: a user-level cache for precompiled fonts, then making that cache read-only by default so nothing is written unless asked. The font data itself tracks Unifont v16.0.02.

◆ Where it's heading

Each release does two things — resync with a newer GNU Unifont and shave the cost of using it. The performance thread has been the more consequential one, moving from the ucp argument that restricts which code points get read, to a full precompiled cache. Version 1.0.0 also walked back the R 4.1 pipe to keep the package usable on R 4.0.

◆ Prediction

Future releases most likely follow GNU Unifont's own version cadence, with occasional cache or loading refinements.
