[cl-ppcre-devel] using parse-tree-synonyms to extend character classes...

[Gary King]

Should i expect the following to work?

(define-parse-tree-synonym
   hostname-char #.(cl-ppcre::parse-string "[-a-zA-Z0-9_.]"))

(define-parse-tree-synonym
   pathname-char (:char-class hostname-char #\: #\@ #\& #\? #\= #\+
                              #\, #\! #\/ #\~ #\* #\' #\% #\\ #\$))
(define-parse-tree-synonym
   pathname (:sequence (:greedy-repetition 0 nil pathname-char)))

(scan-to-strings
     '(:sequence pathname) "My page is at http://www.metabang.com/foo/ 
boo.")

 > Error: Unknown symbol HOSTNAME-CHAR in character class
 > While executing: PPCRE::CONVERT-CHAR-CLASS-TO-HASH
 > Type Command-. to abort.
See the Restarts… menu item for further choices.
