Install an extension manually using the cache

Description

Looks the extension up in cache. On a hit the cached .duckdb_extension file is copied into the connection's extension_directory. On a miss ext_download() is invoked first to populate the cache, and the freshly-cached file is copied.

  name,
  cache = ext_cache(),
  repo = "core",
  conn = conn_default()
)

Arguments

name	Character scalar. Extension name.
cache	An ext_cache object.
repo	"core" or "community". Forwarded to ext_download() on cache miss.
conn	A DuckDB connection.

Value

Invisibly returns conn.
