frontmatter
A small R parser quietly becoming format-agnostic about front matter.
A side-by-side editorial comparison of cheetahR and hubValidations — 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.
Submission validation for forecast hubs, rebuilt around which file each check belongs to.
hubValidations checks submissions to collaborative forecasting hubs — file names, schemas, task-id combinations, sample structure — and runs inside pull-request automation on the hub repository. The package crossed a 2.0.0 boundary that reorganised how multi-file validation results are represented, and the releases since have been narrow additions to sample checking and fixes to the GitHub API integration. Its surface is large, with individual named checks as the unit of extension.

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.
hubValidations checks submissions to collaborative forecasting hubs — file names, schemas, task-id combinations, sample structure — and runs inside pull-request automation on the hub repository.

Its surface is large, with individual named checks as the unit of extension.
The architectural work is done and the package has returned to incremental check-writing, particularly around samples, where model tasks can carry independent configurations. A parallel thread makes validation output more communicative: informational warnings that do not fail a submission, prominent display of config-file changes, and clearer errors where a cryptic dplyr failure used to surface. The GitHub integration keeps producing small defects, being the one part not exercised by ordinary local use.
Expect further sample-related checks and continued refinement of what validation output communicates to hub maintainers, rather than another architectural change so soon after 2.0.0.
