Encode::Escape::ASCII - Perl extension for Encoding of ASCII Escape Sequnces (or Escaped ASCII)
use Encode::Escape::ASCII; $escaped = "Perl\\tPathologically Eclectic Rubbish Lister\\n"; $string = decode 'ascii-escape', $escaped; # Now, $string is equivalent to "Perl\tPathologically Eclectic Rubish Lister\n"; $escaped = "\\x65\\x50\\x6c\\x72\\x50\\x09\\x74\\x61\\x6f\\x68\\x6f\\x6c" . "\\x69\\x67\\x61\\x63\\x6c\\x6c\\x20\\x79\\x63\\x45\\x65\\x6c" . "\\x74\\x63\\x63\\x69\\x52\\x20\\x62\\x75\\x73\\x69\\x20\\x68" . "\\x69\\x4c\\x74\\x73\\x72\\x65\\x0a"; $string = decode 'ascii-escape', $escaped; # Now, $string is equivalent to "Perl\tPathologically Eclectic Rubish Lister\n";
If you have a text data file 'ascii-escape.txt'. It contains a line:
Perl\tPathologically Eclectic Rubbish Lister\n
And you want to use it as if it were a normal double quote string in source code. Try this:
open(FILE, 'ascii-escape.txt'); while(<FILE>) { chomp; print decode 'ascii-escape', $_; }
Encode::Escape::ASCII module implements encoding of ASCII escape sequences.
Simply saying, it converts (decodes) escape sequences into ASCII chracters (0x00 -- 0x7f) and converts (encodes) non-printable control characters into escape sequences.
It supports only ASCII character. ASCII is called as low ASCII or 7-bit ASCII when one distinguishes it from various extended ASCII codes, i.e. high ASCII or 8-bit ASCII.
