gexp: Allow bytevector as content of `plain-file'.
This allows for using a package source directly from git, doing something like (define (command->bytevector command) (let ((port (apply open-pipe* OPEN_READ command))) (let ((output (get-bytevector-all port))) (close-port port) output))) (define-public hello-git (package (name "hello") (version "git") (source (let* ((commit "stable-2.0") (content (command->bytevector `("git" "archive" "--format" "tar" "--prefix" ,(string-append commit "/") ,commit))) (file-name (string-append "hello-" commit))) (plain-file file-name content))) ... )) * guix/gexp.scm (<plain-file>): Also allow bytevector content. (plain-file-compiler): Handle bytevector content. * doc/guix.texi (G-Expressions): Describe plain-file now also taking bytevectors.
