| | Obfuscated code - Wikipedia, the free encyclopedia |
 | | Source code obfuscators are often buggy because most are built using simple-string munging tools that fail to account for all the complexities of the source language syntax. | | | For binary obfuscators, there is little one can do except find or create a newer version or fiddle with any inputs to the obfuscator until it magically works. | | | Occasionally an obfuscator may be buggy, in a difficult to reproduce way. |

| | Perl |
| | Perl was designed to be a practical language to extract information from text files and to generate reports from that information. | | | Perl is one of the programming language components of the popular LAMP free software platform for web development. | | | Rather, perl (the program) first compiles an entire program into an internal form (a parse tree) which is then optimized before being run. |

| | Preface (Programming Perl) |
| | Because Perl is both powerful and accessible, it is being used daily in every imaginable field, from aerospace engineering to molecular biology, from mathematics to linguistics, from graphics to document processing, from database manipulation to network management. | | | Because of its heritage, Perl was a rich language even when it was "just" a data-reduction language, designed for navigating files, scanning large amounts of text, creating and obtaining dynamic data, and printing easily formatted reports based on that data. | | | Perl doesn't impose arbitrary limitations on your data--your strings and arrays can grow as large as they like (as long as you have memory), and they're designed to scale well as they grow. |

| | The 0th Annual Obfuscated Perl Contest Results - The Perl Journal, Autumn 1996 |
| | While the code isn't highly obfuscated, the idea of a program reading itself and then using a mural to make a string is pretty nifty. | | | Robert's code wasn't highly obfuscated; most of the difficulty of reading it came from the fact that it's got a lot of math in it. | | | No, they each created code so vicious, so grotesque, that if the U.S. State Department were to find out about obfuscated Perl code of this caliber, they'd immediately declare it an unexportable munition. |

| | Amazon.com: Computer Science & Perl Programming: Best of TPJ: Books |
| | Computer Science and Perl Programming is the first volume of The Best of the Perl Journal, compiled and re-edited by the original editor and publisher of The Perl Journal, Jon Orwant. | | | Other books (even Programming Perl by comparison) relatively thoroughly demonstrate and document the language features but only this one shows each feature shining as it solves real problems in real problems taken from real life. | | | The closest example I can think of is the styles and much of the contents of Advanced Perl Programming, Learning Regular Expressions, Learning Algorithms with Perl and several others rolled into one. |

| | In the fine 'just another Perl hacker' tradition, this award is given to the best code which generates the text 'The Perl Journal'. | | | The limit is 1024 bytes of Perl code, not including whitespace. | | | Programs which purposefully crash machines or cause system problems tend to be unamusing, so please consider saving them for the Perl system destroyers' contest. |

| | The Obfuscated Perl Contest Gadgetopia |
| | I really liked this guy (man, “this guy” is apparently one hell of a Perl programmer…), who also used the “extracted string which is eval’d” technique, but which resulted in an ASCII clock which displays the current time. | | | I couldn’t find an actual home page for the contest, but since one of the categories requires entrants to print out “The Perl Journal,” that magazine probably has something to do with it. | | | As I was reading this post I just new that I had to comment along the lines of, “isn’t every Perl program obfuscated?” |

| | SelfGOL's source is under 1000 bytes of standard Perl, does not import any modules, and doesn't use a single if, unless, while, until, for, foreach, goto, next, last, redo, map, or grep. | | | It was surprisingly instructional to see how some of the more obscure features of Perl work, and recognize why outdated features existed in the first place. | | | Devising the shortest possible quine in some given programming language is a common hackish amusement. |

I do that regurlarly and have no problems adding new features to code that are years old. | | | The syntax of Python *is* easier to the eye and the indentation syntax is, IMHO, more forgiving for aspiring programmers. | | | Also, using Perl for large projects require experience and coding discipline, something that it takes years to learn. |

| | Just another Perl hacker |
| | A variant of this, practiced by programmers working on the Parrot project, involves Parrot assembly programs printing the phrase "Just another Parrot hacker": | | | or from having "Just another Perl hacker," embedded in opaque code: | | | The obfuscation can result from the code being total gibberish, e.g.: |

| | It's just a compressed version of a more rational but very short program, shaven down to its bare minimum length so that it meets the requirements of The Perl Journal's Second Annual Obfuscated Perl Contest, being a self-contained game comprising 512 bytes or fewer. | | | While it is his first attempt at such a competition, the program is actually a port of a game he wrote in Apple BASIC in 1990, as a high school project. | | | You can read the rules and storyline and view the obfuscated or readable versions of the game's source code, or get the entire tarball of all files as submitted to the contest. |

| | I've usually suggested that people write their code, "Like you'll need to look at it in 6 months." I still contend that the benefit of VB was that it was [usually] fairly easy to pick up some code you might have written months earlier and understand it fairly quickly. | | | However, why do people intentionally obfuscate their code when writing for a team? | | | Whether it's a contest, or inheriting someone's code that felt it was their "job security", there is a lot of obfuscated code out there.
I can almost understand the contests, as that's just sport (however, I see there is also an Obfuscated Perl Contest. |
