;; This is a convenience module providing SRFI-88 "keyword object". All it | |
;; does is setup the right reader option and export keyword-related | |
;; convenience procedures. | |
;;; Code: | |
(define-module (srfi srfi-88) | |
#:re-export (keyword?) | |
#:export (keyword->string string->keyword)) | |
(cond-expand-provide (current-module) '(srfi-88)) | |
;; Change the keyword syntax both at compile time and run time; the latter is | |
;; useful at the REPL. | |
(eval-when (expand load eval) | |
(read-set! keywords 'postfix)) | |
(define (keyword->string k) | |
"Return the name of @var{k} as a string." | |
(symbol->string (keyword->symbol k))) | |
(define (string->keyword s) | |
"Return the keyword object whose name is @var{s}." | |
(symbol->keyword (string->symbol s))) | |
