I would say you can get 80% of the way there by
* treating each line as if it where a separate command
* treating the backspace (^H) and delete (^?) characters as backspaces
* ignoring (ESC)
but there will certainly be problems with this solution.
#!/usr/bin/perl
use strict;
use warnings;
while (<>) {
s/\(ESC\)//g; #remove escapes
my @visible;
for my $char (split //) {
if (ord $char == 8 or ord $char == 127) {
pop @visible;
next;
}
push @visible, $char;
}
print @visible;
}
