Return the sorted list of inferior packages matching NAME in INFERIOR, with highest version numbers first. If VERSION is true, return only packages with a version number prefixed by VERSION.

Evaluate EXP in INFERIOR.

Open the inferior Guix in DIRECTORY, running 'DIRECTORY/COMMAND repl' or equivalent. Return #f if the inferior could not be launched.

Return the source code location of PACKAGE, either #f or a <location> record.

Return the Texinfo synopsis of PACKAGE, an inferior package. When TRANSLATE? is true, translate it to the current locale's language.

Return the replacement for PACKAGE. This will either be an inferior package, or #f.

Return a directory containing a guix filetree defined by CHANNELS, a list of channels. The directory is a subdirectory of CACHE-DIRECTORY, where entries can be reclaimed after TTL seconds. This procedure opens a new connection to the build daemon. AUTHENTICATE? determines whether CHANNELS are authenticated.

VALIDATE-CHANNELS must be a four-argument procedure used to validate channel instances against REFERENCE-CHANNELS; it is passed as #:validate-pull to 'latest-channel-instances' and should raise an exception in case a target channel commit is deemed "invalid".

When VERIFY-CERTIFICATE? is true, raise an error when encountering an invalid X.509 host certificate; otherwise, warn about the problem and keep going.

Return the derivation for PACKAGE, an inferior package, built for SYSTEM and cross-built for TARGET if TARGET is true. The inferior corresponding to PACKAGE must be live.

Evaluate CODE in INFERIOR, passing it STORE as its argument. CODE must thus be the code of a one-argument procedure that accepts a store.

Read a (guix repl) response from PORT and return it as a Scheme object. Raise '&inferior-exception' when an exception is read from PORT.
