Return an object representing the executable store item NAME that runs GEXP. GUILE is the Guile package used to execute that script. Imported modules of GEXP are looked up in MODULE-PATH.

This is the declarative counterpart of 'gexp->script'.

Return a derivation that contains the source files of MODULES, a list of module names such as `(ice-9 q)'. All of MODULES must be either names of modules to be found in the MODULE-PATH search path, or a module name followed by an arrow followed by a file-like object. For example:

(imported-modules `((guix build utils) (guix gcrypt) ((guix config) => ,(scheme-file …))))

In this example, the first two modules are taken from MODULE-PATH, and the last one is created from the given <scheme-file> object.

Return the list of Guile module names GEXP relies on. If (gexp? GEXP) is false, meaning that GEXP is a plain Scheme object, return the empty list.

Return a file that contains the list of direct and indirect references (the closure) of ITEM.

Import FILES into the store and return the resulting derivation or store file name (a derivation is created if and only if some elements of FILES are file-like objects and not local file names.) FILES must be a list of (FINAL-PATH . FILE) pairs. Each FILE is mapped to FINAL-PATH in the resulting store path. FILE can be either a file name, or a file-like object, as returned by 'local-file' for example.

Return an object representing a text file called NAME with the given CONTENT (a string) to be added to the store.

This is the declarative counterpart of 'text-file'.
