SgfStrip

Chris Hayashida: I always found that the SGF files from KGS/CGoban2 were annoying because of the circles...Anyway, here is my answer:

#!/usr/bin/perl
#
# sgfstrip.pl
# by Chris Hayashida
#
# Usage: perl sgfstrip.pl <input filename> > <output filename>
#
# This script removes the CR and time tags from the KGS SGF
# files. It can also accept input from standard input and send
# output to standard output.

while (<>) {
    s/CR\[..\]//g;
    s/WL\[.*?\]//g;
    s/BL\[.*?\]//g;
    print;
}

This Perl script will remove the CR, and WL/BL (time) tags from the SGF file. I had a version that also did comments (C tag) so that I could load SGF files from KGS et al. into PilotGOne.

Hope this helps someone.

uncomment.pl

Thanks the sgfstrip script I was encouraged to write the following simple script to remove all the comments from a sgf file. Not only related to KGS files.

#!/usr/bin/perl
#
# uncomment.pl
# by Frankmartin Wiethuechter
#
# Usage: perl uncomment.pl <input filename>    >    <output filename>
#
# This script removes all C tags from SGF files.
# It can also accept input from standard input and send
# output to standard output.

while (<>) {
    s/C\[.*?\]//g;
    print;
}

I use the script to port commented problem sgf files to files for a problem player like HactarGo.

This issue has been discussed a while ago - a page "CR Marks on Moves" seems to have gone, but see also Cgoban problems and solutions and rgg
