I also found myself migrating from Apache::ASP to Mason. I must say, I'm much happier with Mason, personally.
Here's a quick hack that can migrate the template format of a set of files from Apache::ASP to Mason. You still have to change any use of the Apache::ASP objects over, of course.
#!/usr/bin/perl
#foreach $file ( split(/\n/, `find . -depth -print`) ) {
# next unless $file =~ /(cgi|html)$/;
foreach $file ( @ARGV ) {
open(F,$file) or die "can't open $file for reading: $!";
@file = <F>;
#print "$file ". scalar(@file). "\n";
close $file;
$newline = ''; #avoid prepending extraneous newlines
$all = join('',@file);
$w = '';
$mode = 'html';
while ( length($all) ) {
if ( $mode eq 'html' ) {
if ( $all =~ /^(.+?)(<%=?.*)$/s && $1 !~ /<%/s ) {
$w .= $1;
$all = $2;
next;
} elsif ( $all =~ /^<%=(.*)$/s ) {
$w .= '<%';
$all = $1;
$mode = 'perlv';
#die;
next;
} elsif ( $all =~ /^<%(.*)$/s ) {
$w .= $newline; $newline = "\n";
$all = $1;
$mode = 'perlc';
#avoid newline prepend fix from borking indented first <%
$w =~ s/\n\s+\z/\n/;
$w .= "\n" if $w =~ /.+\z/;
next;
} elsif ( $all !~ /<%/s ) {
$w .= $all;
last;
} else {
warn length($all); die;
}
die;
} elsif ( $mode eq 'perlv' ) {
if ( $all =~ /^(.*?%>)(.*)$/s ) {
$w .= $1;
$all=$2;
$mode = 'html';
next;
}
die "unterminated <%= ??? (in $file):";
} elsif ( $mode eq 'perlc' ) {
if ( $all =~ /^([^\n]*?)%>(.*)$/s ) {
$w .= "%$1\n";
$all=$2;
$mode='html';
next;
}
if ( $all =~ /^([^\n]*)\n(.*)$/s ) {
$w .= "%$1\n";
$all=$2;
next;
}
} else { die };
}
system("chmod u+w $file");
select W; $| = 1; select STDOUT;
open(W,">$file") or die "can't open $file for writing: $!";
print W $w;
close W;
}
