Changelog

Source: NEWS.md

tarchives (development version)

• tar_check_archive_pipeline() and tar_check_archive_name() validate a pipeline or target name against the ones available in a package, erroring with a “did you mean” suggestion when the value doesn’t match.
• tar_get_archive() (experimental) builds an archived pipeline (if outdated) and reads a target’s value in one call, skipping the build on repeat calls for the same installed package version within a session.
• tar_make_archive() (and therefore tar_get_archive() and tar_target_archive()) now reports which package and pipeline failed to build, with the original error attached. When the build fails because a package isn’t installed, it explains that packages needed only for building are often suggested dependencies and how to install them (#17).
• tar_make_archive() (and therefore tar_get_archive() and tar_target_archive()) now locks the archived store while building, so R processes that request the same archive at the same time (e.g. parallel workers) build it one at a time instead of corrupting the store. tarchives now imports filelock (#16).

tarchives 0.2.0

CRAN release: 2026-07-12

• The archive functions now validate their package and pipeline arguments and report a clear error when the package or pipeline cannot be found.
• tarchives no longer depends on usethis.
• tar_archive_pipelines() lists the pipelines bundled in a package.
• tar_archive_pipelines(), tar_archive_script(), tar_make_archive(), tar_manifest_archive(), and tar_source_archive() now correctly resolve package when it is loaded with pkgload::load_all() (e.g. during interactive package development), instead of silently falling back to the installed copy.
• tar_destroy_archive() removes the cached store of an archived pipeline.
• tar_load_archive() loads archived targets into an environment.
• tar_manifest_archive() lists the targets defined in an archived pipeline.
• tar_meta_archive() reads the metadata of an archived pipeline’s store.
• tar_read_archive(), tar_load_archive(), and tar_meta_archive() now fail with an informative error when the archived store has not been built yet.
• tar_target_archive() now builds and reads the archive when the target runs rather than when the target script is sourced, so inspecting a pipeline with tar_manifest() or tar_visnetwork() no longer triggers a build. The target tracks the installed version of the package, so it refreshes the data when a new version of the package providing the archive is installed and is skipped otherwise.
• Tests no longer leave files in the user cache directory (tools::R_user_dir("tarchives", "cache")) during R CMD check, which caused the package to be archived on CRAN.

tarchives 0.1.1

CRAN release: 2025-06-22
