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.

[cl-ppcre-devel] Why is parse-string not exported
