Return a derivation to construct a Docker image of PROFILE. The image is a tarball conforming to the Docker Image Specification, compressed with COMPRESSOR. It can be passed to 'docker load'. If TARGET is true, it must a be a GNU triplet and it is used to derive the architecture metadata in the image. EXTRA-OPTIONS may contain the IMAGE-TAG keyword argument. If MAX-LAYERS is not false, the image will be split in up to MAX-LAYERS layers.

A SRFI-37 option parser for the --symlink option. The symlink spec accepts the link file name as its left-hand side value and its target as its right-hand side value. The target must be a relative link.

Return a squashfs image containing a store initialized with the closure of PROFILE, a derivation. The image contains a subset of /gnu/store, empty mount points for virtual file systems (like procfs), and optional symlinks.

SYMLINKS must be a list of (SOURCE -> TARGET) tuples denoting symlinks to be added to the pack.

Return a self-contained tarball containing a store initialized with the closure of PROFILE, a derivation. The tarball contains /gnu/store; if LOCALSTATEDIR? is true, it also contains /var/guix, including /var/guix/db with a properly initialized store database.

SYMLINKS must be a list of (SOURCE -> TARGET) tuples denoting symlinks to be added to the pack.

Return a Debian archive (.deb) containing a store initialized with the closure of PROFILE, a derivation. The archive contains /gnu/store; if LOCALSTATEDIR? is true, it also contains /var/guix, including /var/guix/db with a properly initialized store database. The supported compressors are "none", "gz" or "xz".

SYMLINKS must be a list of (SOURCE -> TARGET) tuples denoting symlinks to be added to the pack. EXTRA-OPTIONS may contain the CONFIG-FILE, POSTINST-FILE or TRIGGERS-FILE keyword arguments.

Return a RPM archive (.rpm) containing a store initialized with the closure of PROFILE, a derivation. The archive contains /gnu/store. SYMLINKS must be a list of (SOURCE -> TARGET) tuples denoting symlinks to be added to the pack. ARCHIVER and ENTRY-POINT are not used. RELOCATABLE?, PREIN-FILE, POSTIN-FILE, PREUN-FILE and POSTUN-FILE can be provided via EXTRA-OPTIONS.

create application bundles

Return a self-contained AppImage containing a store initialized with the closure of PROFILE, a derivation. The AppImage contains /gnu/store unless RELOCATABLE option is used; if LOCALSTATEDIR? is true, it also contains /var/guix, including /var/guix/db with a properly initialized store database.

SYMLINKS must be a list of (SOURCE -> TARGET) tuples denoting symlinks to be added to the pack.

Return environment variable definitions that may be needed for the use of ENTRIES, a list of manifest entries, in PROFILES. Use GETENV to determine the current settings and report only settings not already effective. KIND must be one of 'exact, 'prefix, or 'suffix, depending on the kind of search path definition to be returned.

manage packages and profiles

Build a new generation of PROFILE, a file name, using the packages specified in MANIFEST, a manifest object. When ALLOW-COLLISIONS? is true, do not treat collisions in MANIFEST as an error. HOOKS is a list of "profile hooks" run when building the profile.

Search among all the versions of ENTRY's package that are available, and return the shortest unambiguous version prefix for this package. If only one version of ENTRY's package is available, return the empty string.

Write to the current output port the list of packages matching REGEXP in PROFILES.

Delete from PROFILE all the generations matching PATTERN. PATTERN must be a string denoting a set of generations: the empty list means "all generations but the current one", a number designates a generation, and other patterns denote ranges as interpreted by 'matching-generations'.

Delete GENERATIONS from PROFILE. GENERATIONS is a list of generation numbers.

Run the 'guix package' command on OPTS, an alist resulting for command-line option processing with 'parse-command-line'.

Return a variant of TRANSACTION that accounts for the upgrade of ENTRY, a <manifest-entry>.
