[Note: you no longer need to pre-load km.lisp before compiling, as described in the manual] To start the query interpreter running, type (km): > (km) KM> See the User Manual and Reference Manual for instructions on using KM, and building knowledge bases. The manuals are available at: ====================================================================== READING/EDITING THE SOURCE: ====================================================================== The following file is a machine-built concatenation of the various files in the KM inference system. It can be loaded or compiled directly into Lisp, deconcatenation is not necessary for running KM. Although you can read/edit the below code all in this one file, it is very large and unweildy; you may prefer to break it up into the (approx 20) constituent files which it comprises. You can break it up either manually, looking for the ";;; FILE: <file>" headers below which denote the start of different files in this concatenation, OR use the Perl unpacker below which automatically cut this big file into its consistutent files. Peter Clark ====================================================================== DISASSEMBLING THIS CONCATENATION INTO ITS CONSTITUENT FILES: ====================================================================== Note you don't have to disassemble km.lisp to use KM. However, if you want to read/edit the code, you might find it helpful to break it up into individual files. If you do disassmble the files, then the single file loadme.lisp contains (commented out) load commands to load all the other constituent files, for your convenience. (Don't forget to uncomment the load commands in this file). If you don't disassemble the files and just work with km.lisp, then you can ignore all of this. Option 1. (For Emacs users) [Thanks to Joe Corneli for this piece of code!] [(1) Ignore end-of-line whitespace - thanks to Nate Blaylock] [(2) Thanks to Dan Tecuci pointing out "-" needs to be the last character in the regexp, otherwise it has the meaning of a character range delimeter.] (save-excursion (let ((case-fold-search nil)) (goto-char (point-min)) ; (while (re-search-forward "^;;; FILE: +\\(.*\\)" nil t) [see (1) above] ; (while (re-search-forward "^;;; FILE: +\\([a-zA-Z-\\._]+\\)" nil t) [(2)] (while (re-search-forward "^;;; FILE: +\\([a-zA-Z\\._-]+\\)" nil t) (let* ((matched (match-string 1)) (beg (match-beginning 0)) (end (or (save-excursion (when (search-forward-regexp "^;;; FILE: +.*" nil t) (match-beginning 0))) (point-max))) (str (buffer-substring beg end))) (with-temp-file matched (save-excursion (insert str)) (next-line 1) ; uncomment the below lines if you want KM files to have KM package declaration (insert (concat "(unless (find-package :km) (make-package :km :use '(:common-lisp)))\n" "(in-package :km)\n")) ))))) ^ position cursor behind the emacs lisp expression above and run M-x eval-last-sexp Option 2. (For non-Emacs users) 1. cut and paste the short Perl script below to a file, eg called "disassemble" 2. Make sure the first line is #!/usr/local/bin/perl and edit this path /usr/local/bin/perl as needed to point to the local version of Perl. 3. Make the file executable: % chmod a+x disassemble 4. Now disassemble km.lisp: % disassemble km.lisp This will populate the current directory with the approx. 20 Lisp files constituting the KM system. ------------------------------ cut here ------------------------------ #!/usr/local/bin/perl # Splits file with internal file markers of the form: # ;;; FILE: <filename> # into individual files in the current directory. # Outputs to stdout information about processing. # require 5.0; $lineno = 0 ; if ($#ARGV != 0) { die "Usage: $0 filename.";} # 1 and only 1 arg $fn = shift(@ARGV); open(PACKED, "<$fn") || die "Could not open file $fn\n "; $_ = <PACKED>; $lineno += 1; # Read first line, and count it chop; ($junk, $outfile) = split (/:/); unless ($junk != /^;;; FILE/o) { die "Missing file tag ;;; FILE: Line number $lineno." } # Open file for writing unless (open (OUTFILE, ">$outfile")) { die "Could not open file $outfile for writing."; } print "$outfile created\n"; while (<PACKED>) { $lineno += 1; ($junk, $outfile) = split (/:/); if ($junk =~ /^;;; FILE/o) { close (OUTFILE); chop($outfile); unless (open (OUTFILE, ">$outfile")) { die "Could not open file $outfile for writing. Line number $lineno."; } print "$outfile created\n"; # uncomment the below line if you want KM files to have KM package declaration print (OUTFILE "\n(unless (find-package :km) (make-package :km :use '(:common-lisp)))\n"); print (OUTFILE "(in-package :km)\n"); } else { print (OUTFILE $_); } } close(PACKED); close(OUTFILE); print "Completed without errors.
