rd-helpdb
rd-helpdb reads the compiled help database of an installed R package and provides alias, topic, and help-search access.
Overview
An installed package help database consists of help/aliases.rds, the help/<pkg>.rdx index and help/<pkg>.rdb record pair, and Meta/hsearch.rds. rd-helpdb reads the standalone RDS files and the compressed records addressed by the .rdx index; it does not discover package directories through R's .libPaths().
Standalone .rds envelope handling is delegated to rd-rds. Consumers that need a canonical document model can lower decoded help objects into rd-ast.
Stability
Alias, topic, and search reading for an explicitly named installed-package directory is supported. Discovering R libraries or packages on a machine is out of scope; see the workspace stability policy.
