hubValidations
Submission validation for forecast hubs, rebuilt around which file each check belongs to.
A side-by-side editorial comparison of cheetahR and frontmatter — release velocity, themes, recent moves, and the top alternatives to consider.
A canvas grid wrapper aiming at the row counts where R's HTML table widgets stop being usable.
cheetahR wraps the Cheetah Grid JavaScript library as an R htmlwidget, positioned by its authors as an alternative to reactable for large datasets. The Shiny surface is now substantial: proxy functions, numeric and date column formatters, sorting, search, column groups, inline and menu cell editors, and a get_grid_data() helper that returns live grid contents as a reactive data frame. The most recent release adds an autocomplete column that suggests values from a list while still accepting free text.
A small R parser quietly becoming format-agnostic about front matter.
frontmatter extracts and writes YAML or TOML front matter from text documents, with a C++ parser and pluggable YAML and TOML backends. Three releases across six months have taken it from read-only parsing to full roundtrip and then to inferring format automatically. Its scope is deliberately narrow: locating and delimiting the metadata block, and delegating the actual parsing to other packages.

The most recent release adds an autocomplete column that suggests values from a list while still accepting free text.
The arc moves from rendering to editing. Early releases added the read-side affordances a table needs, sorting, search and column grouping, while the last two have been about the grid as an input: proxy functions, cell editors, a typeahead column, and a way to read the edited state back into Shiny. The releases are sparse, roughly three in fourteen months, so this is steady rather than fast work, and the fix in 0.4.0 for renderCheetah() stacking duplicate grids suggests the Shiny integration is still being shaken out under real reactive use.
The editing thread points at more column action types and validation on committed values, since an autocomplete that accepts arbitrary text leaves the checking to the app. The performance claim that motivates the package is asserted rather than measured anywhere in these entries.

Its scope is deliberately narrow: locating and delimiting the metadata block, and delegating the actual parsing to other packages.
Each release widens the set of files it recognises without widening what it claims to do — standard YAML and TOML fences first, then comment-wrapped R and Python variants and PEP 723 inline script metadata, then shebang-prefixed scripts. The complementary thread is preserving what it found: format and fence type are attached as attributes so a document can be rewritten in the style it arrived in. The remaining rough edge is acknowledged in the notes, since comments and formatting inside the front matter do not survive a roundtrip.
Expect further delimiter styles as they appear in the wild, and likely work on making the roundtrip preserve comments and formatting, which the package currently flags as imperfect.
