Evaluate SEARCH-PATHS, a list of search-path specifications, for DIRECTORIES, a list of directory names, and return a list of specification/value pairs. Use GETENV to determine the current settings and report only settings not already effective.

Return an sexp representing SPEC, a <search-path-specification>. The sexp corresponds to the arguments expected by `set-path-environment-variable'.

Similar to 'environment-variable-definition', but applied to a <search-path-specification>.

Set the search path environment variables specified by SEARCH-PATHS for the given directories.

Convert SEXP, which is as returned by 'search-path-specification->sexp', to a <search-path-specification> object.

Return a the definition of VARIABLE to VALUE in Bash syntax.

KIND can be either 'exact (return the definition of VARIABLE=VALUE), 'prefix (return the definition where VALUE is added as a prefix to VARIABLE's current value), or 'suffix (return the definition where VALUE is added as a suffix to VARIABLE's current value.) In the case of 'prefix and 'suffix, SEPARATOR is used as the separator between VARIABLE's current value and its prefix/suffix.

Return, as a monadic value, the derivation to build the Guix from SOURCE for GUILE-VERSION. Use VERSION as the version string. Use CHANNEL-METADATA as the channel metadata sexp to include in (guix config).

PULL-VERSION specifies the version of the 'guix pull' protocol. Return #f if this PULL-VERSION value is not supported.

Return a file-like object that contains a compiled Guix.

Return the whole Guix package NAME that uses MODULES, a derivation of all the modules (under share/guile/site and lib/guile), and DEPENDENCIES, a list of packages depended on. COMMAND is the 'guix' program to use; INFO is the Info manual.

Read a file (possibly a directory structure) in Nar format from PORT. Call PROC on each file or directory read from PORT using:

(PROC FILE TYPE CONTENTS RESULT)

using SEED as the first RESULT. TYPE is a symbol like 'regular, and CONTENTS depends on TYPE.
