Select an Immutable Registry Release

resolve_registry

Source: packages/r/R/registry.R, packages/r/man/registry.Rd

Construct, discover, set, or inspect a strong registry selector. A catalog lookup is TLS-trusted discovery; recording and reusing its returned release and digest creates the reproducible selector.

Usage

registry_selector(release, index_sha256, index_url, schema_version = 1L)

resolve_registry(release, catalog_url = NULL)

set_registry(registry)

active_registry(project_dir = getwd())

Arguments

• release

  A registry release identifier.

• index_sha256

  The lowercase SHA-256 of the exact index bytes.

• index_url

  An absolute HTTP or HTTPS retrieval URL.

• schema_version

  The selector schema version.

• catalog_url

  An HTTPS catalog URL. The package default is used when this is NULL.

• registry

  A strong registry selector, or NULL to clear the session setting.

• project_dir

  The directory from which to search upward for a project selector.

Value

registry_selector(), resolve_registry(), and active_registry() return a datamonger_registry. The setter returns NULL invisibly.
