thanks for your sed solution!

Based on your code, I made a Perl based filter doing the same as pmp
to use it in Windows environment because I thought Perl is more likely
installed on Windows machines than a unixoid shell and sed.

When I was ready, I found that there is a tiny native sed for windows
available from http://sourceforge.net/projects/unxutils/ and a bloated
but more recent version at http://sourceforge.net/projects/gnuwin32/.
To use it in a windows environment, it's IMO suitable to save your
script to a file and call sed -f pmp.sed Group.Name

Well, here is the Perl code, anyway:

- snip -
my $text;

if($ARGV[0] eq ''){
  print STDERR "Script to pretty-print PmWiki page files\n";
  print STDERR "Usage: $0 infile [outfile]\n";

if((-f($ARGV[0])) == 0){
  print STDERR "couldn\'t open $ARGV[0]\n";

if($ARGV[1] ne ''){
  open(OUTFILE, ">$ARGV[1]") or die "couldn\'t open $ARGV[1]";
  open(OUTFILE, ">-") or die "couldn\'t write to STDOUT";

open( FILE, $ARGV[0] ) or die "Can't open $ARGV[0]";

while(<FILE>) {
  next if/^[^=]+:.*/;  # skip history lines (no '=' before ':')

  if( /^text=(.*)/ ) {
    $text = $1; # remember page text
    printf OUTFILE "%10s | %s\n", $1, $2;
}  # while
close( FILE );

$text =~ s/%0a/\n/g;
$text =~ s/%3c/</g;
$text =~ s/%25/%/g;
print OUTFILE "$text\n";

close OUTFILE;



- snip -

With such a filter one can compare two page text files in a neat side
by side view using a "visual" diff tool *).

That's extremly useful for maintenance - consider checking local
modifications of PmWiki supplied pages when updating PmWiki. Or to
merge pages between wikis.

Works also very good by accessing the page files via sftp.
