APPendIX C Perl Code examples This appendix provides Perl equivalents of some algorithms presented in Chapter 9 as C or Java code. While the C and Java code examples in Chapter 9 are useful for developing your own commercial-grade software, these Perl equivalents are helpful for internal-use tools. If you do not use Perl, feel free to skip this appendix. But, in the same vein, I encourage you to explore the Perl programming language to see whether it can offer you something. I use nothing but Perl for virtually all of my programming needs. * A few of these Perl code examples began their life as code courtesy of regex wizard Jeffrey Friedl, author of a most excellent book entitled Mastering Regular Expressions, Third Edi- tion (O'Reilly Media, 2006). Tom Christiansen and Nathan Torkington's Perl Cookbook, Second Edition (O'Reilly Media, 2003) should also be used, because it provides a wealth of incredibly useful Perl examples. Japanese Code Conversion The programs presented in the following sections perform Japanese code conversion. Note that all of them support ASCII (JIS-Roman), JIS X 0208:1997, and half-width ka- takana (even for ISO-2022-JP encoding, which, technically, does not support half-width katakana). * In retrospect, I should have instead learned the Ruby programming language, if for no other reason than my daughter's name is Ruby. 737
