[cl-ppcre-devel] using cl-ppcre functions without package prefixes
Hello, I know this is more of just a pure Lisp question, but i cannot figure out how to get my Lisp program to use cl-ppcre without having to prefix the function calls with 'cl-ppcre' My application is using ASDF to define and load itself: (asdf:defsystem bank-match :description "Approximate bank matching" :author "Terrence M. Brannon" :maintainer "Terrence M. Brannon" :licence "Artistic" :version "1.0" :serial t :depends-on ("cl-ppcre") :components ( (:file "clean") ) ) (in-package :bank-match) (defun crude-hacks (s) "crude hacks :)" (cl-ppcre:regex-replace "head\\s*office" (cl-ppcre:regex-replace "due\\s*from" (cl-ppcre:regex-replace "hapoalim\\s*branch" s "hapoalim bank") " ") " ") ) -- Terrence Brannon - SID W049945 614-213-2475 (office) 614-213-3426 (fax) 818-359-0893 (cell) ----------------------------------------- This communication is for informational purposes only.

Hi Terrance When you define your bank-match package, you want to _use_ cl-ppcre. For example, (defpackage #:bank-match (:use #:common-lisp #:cl-ppcre)) When you use package A in package B, then the exported symbols of A become available in B.

Append :cl-ppcre into the :use list of your DEFPACKAGE line. For instance: (defpackage :test (:use :cl :cl-ppcre)) Regards.

Your technical question was answered already, but I suspect (I may be wrong, of course) that you make the same mistake many Lisp newbies make - you're confusing packages and systems. A "package" is a first-class Lisp object defined in the ANSI standard. You can read about it here for example: http://gigamonkeys.com/book/programming-in-the-large-packages-and-symbols.ht... (Read the whole book if you haven't done so already.) A "system" (that's a common usage of the name although there's no fixed definition for it) is something that's defined by a defsystem facility like ASDF - it's more or less a collection of source files plus instructions on how they are to be compiled. Very often there's a system and a package of the same name, like it's the case for CL-PPCRE. That doesn't have to be the case, though. The names could be different, one system could define more than one package or no package at all, you can define a package without defining a system, etc. HTH, Edi.
I'm partial to the book "Successful Lisp" but neither book covers ASDF. This tutorial was of great help in the past: http://common-lisp.net/~mmommer/asdf-howto.shtml but it is not quite helping me enough here. In both Case 1 and Case 2 below, my .sbclrc does not change, yet Case 2 works just fine. I would like to be able to do an asdf load on bank-match and have it pull-in cl-ppcre, but as it stands I must manually load it first. (setf asdf:*central-registry* '( ;; *default-pathname-defaults* ;;; #P"C:\\cygwin\\home\\W049945\\prg\\lisp-asdf\\series-2.2.9\\" #P"C:\\cygwin\\home\\W049945\\prg\\lisp-asdf\\cl-ppcre-1.3.2\\" #P"C:\\cygwin\\home\\W049945\\prg\\redick\\lisp\\" #P"C:\\etl\\y.com\\trunk\\zan\\approximate-matching\\src\\lisp\\" )) Case 1: attempt to load cl-ppcre via my defpackage: throw error 'The name "CL-PPCRE" does not designate any package.' relevant source: (defpackage :bank-match (:use :cl :asdf :cl-ppcre) ) (in-package :bank-match) (asdf:defsystem bank-match :description "Approximate bank matching" :author "Terrence M.

I'm sure I'm not the first to build a shortcut to make calls to cl-ppcre a bit clearer. I wrote the function re-place() ... note how much clearer crude-hacks2 is compared to crude-hacks (defun crude-hacks (s) "crude hacks :)" (cl-ppcre:regex-replace "head\\s*office" (cl-ppcre:regex-replace "due\\s*from" (cl-ppcre:regex-replace "hapoalim\\s*branch" s "hapoalim bank") " ") " ") ) (defun re-replace (s replace-list) "input-string replace-list => output-string" (if (null replace-list) s (let* ((replace-expr (car replace-list)) (match (car replace-expr)) (replace (cadr replace-expr)) ) (cl-ppcre:regex-replace match (re-replace s (cdr replace-list)) replace)))) (defun crude-hacks2 (s) (re-replace s '( ("head\\s*office" " ") ("due\\s*from" " ") ("hapoalim\\s*branch" "hapoalim bank") ))) -- Terrence Brannon - SID W049945 614-213-2475 (office) 614-213-3426 (fax) 818-359-0893 (cell) ----------------------------------------- This communication is for informational purposes only.

Your system definition for BANK-MATCH must /depend/ on CL-PPCRE: (asdf:defsystem :bank-match ... :depends-on (:cl-ppcre))
attempt to load cl-ppcre via my defpackage
One day I will write a website about this... Systems (that's what third-party libraries like ASDF are about) and packages (first-class objects defined by the ANSI standard) are not the same thing, in fact they are orthogonal concepts. You cannot load anything with a DEFPACKAGE form. http://gigamonkeys.com/book/ Edi. PS: Why was your email sent to cl-ppcre-devel-bounces@common-lisp.net?
