hubValidations vs saperlipopette: at a glance
What is hubValidations?
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.
What is saperlipopette?
saperlipopette turned Git disasters into practice exercises, then passed peer review
saperlipopette creates disposable Git repositories in a temporary path, each staged into a specific broken or interesting state so users can practice recovering from it. Three releases span October 2025 to May 2026, ending with a 1.0.0 that reflects completed rOpenSci-style peer review — reviewers and editors are named in the release notes.

Submission validation for forecast hubs, rebuilt around which file each check belongs to.
◆ Current state
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.
◆ Where it's heading
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.
◆ Prediction
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.

saperlipopette turned Git disasters into practice exercises, then passed peer review
◆ Current state
saperlipopette creates disposable Git repositories in a temporary path, each staged into a specific broken or interesting state so users can practice recovering from it. Three releases span October 2025 to May 2026, ending with a 1.0.0 that reflects completed rOpenSci-style peer review — reviewers and editors are named in the release notes.
◆ Where it's heading
The package grew its exercise catalogue and then stopped to be reviewed. 0.1.1 added five exercises covering git blame, finding deleted files and lines via git log, ancestry parsing with rev-parse, and worktrees, and added switch/restore instructions alongside the checkout equivalents. 1.0.0 adds no exercises at all: it is interface polish, clarified use cases, documented workflows on every manual page, and internal renaming to align scripts with the functions they contain. Internationalisation was in from 0.1.0, with Spanish and French translations of both messages and commit messages.
◆ Prediction
With review complete and the structure documented, adding exercises is the cheap next move — the 0.1.1 batch shows the pattern. Whether more translations follow depends on contributors the entries do not name.
