rworkflows

Bug Fixes

• Comply with CRAN policy on graceful handling of unavailable internet

resources:

• Add testthat::skip_if_offline() to all tests whose call stacks may reach the internet (test-check_bioc_version.R, test-fill_description.R, test-get_authors.R, test-get_hex.R, test-infer_biocviews.R, test-infer_deps.R).
• Move the existing offline guard up in test-construct_cont.R so that the versions_explicit = TRUE branch (which calls bioc_r_versions()) is also skipped when offline.
• Wrap all examples that may use internet resources in curl::has_internet() so they emit an informative message instead of erroring when offline (bioc_r_versions, construct_runners, fill_description, get_description, get_hex, infer_deps, use_badges, use_workflow).
• Gate internet-dependent code chunks in the bioconductor and rworkflows vignettes on curl::has_internet() so vignette rebuilds degrade gracefully when offline.
• Add curl to Suggests to support the new offline guards in examples

and vignettes.

• Vignettes: replace read.dcf("../DESCRIPTION", ...) with utils::packageDescription("rworkflows", ...) so the setup chunks no longer fail under R CMD check's tools::checkVignettes(), which tangles each vignette to a .R file and sources it from a temp working directory where ../DESCRIPTION does not resolve. The same change is applied to inst/templates/{templateR,docker}.Rmd via a __PKG__ placeholder that use_vignette_getstarted() / use_vignette_docker() substitute at write time.
• use_vignette_getstarted() / use_vignette_docker(): raise a clear error when package is NULL or empty (previously they silently produced a malformed file).

Miscellaneous

• Update system requirements Ubuntu version for Linux runners in actions.
• Bump conda-incubator/setup-miniconda from @v3 to @v4. v4 upgrades the action runtime to Node.js 24, which is supported by GitHub-hosted runners but requires self-hosted runners on a recent actions/runner release.
• Bump actions/checkout from @v4 to @v6 (the bundled example workflow goes from @v3). v5 moved the runtime to Node.js 24 (requires runner >= v2.327.1, satisfied by all GitHub-hosted runners) and v6 persists git auth credentials to a separate .gitauth file instead of .git/config; neither change affects this action.
• Forward the ncpus input to grimbough/bioc-actions/setup-bioc@v1 (as its Ncpus input) so non-Linux R installs use the configured parallel job count instead of the action's default of 3.
• Tests: replace is_gha() gates that were guarding internet access with host-specific skip_if_offline(host=...) calls (bioconductor.org, github.com, raw.githubusercontent.com, ghcr.io) so individual tests skip when their actual remote is unreachable. This includes the get_description Bioc-repo block, which previously gated on is_gha() | is_rstudio() to dodge CRAN flakiness (#65); it now skips on bioconductor.org instead. Each skip_if_offline() is then wrapped in if (!is_gha()) so GitHub Actions exercises the network path regardless of the offline probe; developer machines and CRAN's check farm continue to skip when the named host is unreachable. is_gha() is also retained for the construct_conda_yml env-creation block, where the test is genuinely GHA-only (creates and leaves a conda env behind, so should not run on developer machines).
