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.

Return a manifest entry for the OUTPUT of package PACKAGE.

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

Return a derivation that evaluates EXP with GUIX, an instance of Guix as returned for example by 'channel-instances->derivation'. Other arguments are passed as-is to 'gexp->derivation'.

When SILENT-FAILURE? is true, create an empty output directory instead of failing when GUIX is too old and lacks the 'guix repl' command.

Evaluate EXP in INFERIOR.

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

Return an inferior for CHANNELS, a list of channels. Use the cache at CACHE-DIRECTORY, where entries can be reclaimed after TTL seconds. This procedure opens a new connection to the build daemon.

This is a convenience procedure that people may use in manifests passed to 'guix package -m', for instance.

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.
