Our mailer burped on this one, sorry if you see it twice. ...arun Date: 27 Jan 89 09:24:47 GMT From: mcvax!enea!kth!draken!liuida!uda@uunet.uu.net (Ulf Dahlen) Organization: CIS Dept, Univ of Linkoping, Sweden Subject: 'provide' and 'require' and compiled files Message-Id: <1168@mina.liu.se> To: info-1100@sumex-aim.stanford.edu How is 'provide' and 'require' implemented in existing CL-implementations? I would like 'require' to search for the compiled file first, and load it if it's found. Xerox Lisp has a 'require' that doesn't bother about compiled files. This makes it almost necessary to use the InterLISP function 'FILESLOAD' and that will make programs less portable. Let's say I have a file submodule that does the following: (provide 'submodule) ;;; rest of file Then say I compile this file, getting a submodule.fasl (or whatever extension is used). If I have another file with these statements: (provide 'mainmodule) (require 'submodule) ;;; rest of file I would like this file to load submodule.fasl, not submodule.lisp. The fact that the extension for compiled files is not stated in CLtL, makes it impossible to write (require 'submodule 'submodule.fasl) or something like that. __________ Ulf Dahlen Dept of Computer & Info Science, University of Linkoping, Sweden Troskaregatan 51:23 | uda@ida.liu.se S-583 30 LINKOPING | uda@majestix.liu.se, uda@majestix.UUCP SWEDEN | {mcvax,munnari,seismo}!enea!liuida!uda "The beginning is a very delicate time."
