The error is coming from the use of "#$files"... specifi= cally in the subform "(for-each (lambda (file) ...) #$files)", #$files is r= eplaced--in the usage example--with exactly ("bin/parallel"), resulting in: > (for-each (lambda (file) ...)

Since ("bin/parallel") now l= ooks like a function call, it tries to treat it as one. The three main opti= ons that I know of are to > 1) quote the argument when calling rename-files so that "list" is first i= n the literal list: > (rename-files moreutils '(list "bin/parallel")) > 2) quote the list within the gexp: > (for-each (lambda (file) ...)

(list #@$files) > > In my opinion the second option is probably the easiest and safest to wor= k with. #1 and #3 both suffer from needing to specially craft the incoming = argument to handle being evaluated twice. For #1, the argument has to be a = list after being evaluated twice (the first evaluation is of the quote, the= second occurs after the gexp was expanded and calls list with the string a= rguments). For #3, the expectation of a list is more explicit, but the argu= ment has to evaluate to a list where all of the elements have to then evalu= ate to something meaningful (not too much of an issue for this case as stri= ngs evaluate to themselves). #2 should only require that the evaluated argu= ment has a printable representation that can be read back in, which at leas= t to me feels more natural to work with. > > Hope my early morning explanation helps! > > Cheers, > Kaelyn > > > Backtrace: > > 9 (primitive-load "/gnu/store/qrj9l194a552vpg2234xx55k76j=E2=80=A6") > > In guix/build/gnu-build-system.scm: > > 908:2 8 (gnu-build #:source _ #:outputs _ #:inputs _ #:phases . #) > > In ice-9/boot-9.scm: > > 1752:10 7 (with-exception-handler _ _ #:unwind? _ # _) > > In srfi/srfi-1.scm: > > 634:9 6 (for-each #<procedure 7ffff5b0b140 at guix/build/gnu-b=E2=80=A6= > =E2=80=A6) > > > > In ice-9/boot-9.scm: > > 1752:10 5 (with-exception-handler _ _ #:unwind? _ # ) > > In guix/build/gnu-build-system.scm: > > 929:23 4 () > > In ice-9/eval.scm: > > 159:9 3 (_ #(#(#(#<directory (guile-user) 7ffff77f7c80>) (#)) =E2=80=A6= )) > > > > 159:9 2 (_ _) > > In ice-9/boot-9.scm: > > 1685:16 1 (raise-exception _ #:continuable? _) > > 1685:16 0 (raise-exception _ #:continuable? _) > > > > ice-9/boot-9.scm:1685:16: In procedure raise-exception: > > Wrong type to apply: "bin/parallel" > > --8<---------------cut here---------------end--------------->8--- Kaelyn, Thank you for the detailed explanation.
