Perl: The Comprehensive Geek Bio
Origin: Perl, originally developed as "Practical Extraction and Report Language" (though it also has a backronym "Pathologically Eclectic Rubbish Lister"), was created by Larry Wall in 1987. Wall, a linguist and programmer, developed Perl while working as a systems administrator for NASA, with the goal of combining the best features of various Unix tools into a single, cohesive scripting language.
Version History:
1. Perl 1.0 (1987): The initial release focused on text manipulation and was designed to be a practical language for extracting information from text files and generating reports.
2. Perl 2 (1988): Introduced regular expressions, which significantly enhanced its text-processing capabilities.
3. Perl 3 (1989): Added support for binary data streams, making Perl more versatile.
4. Perl 4 (1991): Focused on improving the documentation and usability.
5. Perl 5 (1994): A major overhaul that introduced a more advanced object-oriented programming model, modularity (using packages and modules), and other improvements. Perl 5 became the most widely used version and had numerous subsequent updates.
6. Perl 6 (2015, later renamed to Raku): Initially intended as a major revision of Perl 5, Perl 6 turned into a separate language. It introduced modern programming features but maintained compatibility with Perl 5 concepts.
7. Perl 7 (Upcoming): Announced to modernize the language and make Perl more accessible to new programmers, while maintaining backward compatibility with Perl 5.
Notable Uses:
- System Administration: Perl scripts are commonly used for automating tasks, managing files, and monitoring system performance.
- Web Development: Perl's CGI (Common Gateway Interface) module was widely used in early web development.
- Bioinformatics: Perl is extensively used for bioinformatics applications due to its strong text processing capabilities.
- Network Programming: Perl is utilized for writing network utilities and performing tasks like web scraping.
Community and Culture:
- Perl Mongers: Local Perl user groups around the world that organize meetings and support the Perl community.
- YAPC (Yet Another Perl Conference): An annual conference that brings together Perl developers and enthusiasts to share knowledge and network.
- The Perl Foundation: An organization dedicated to the advancement of the Perl programming language through various initiatives and funding.
Creator:
Larry Wall, the creator of Perl, is known for his humor and eclectic style, both of which are reflected in Perl's documentation and culture. He is a linguist by training and has a deep appreciation for natural languages, which influenced Perl's design.
Quotes from Larry Wall:
- "Perl is designed to make the easy jobs easy, without making the hard jobs impossible."
- "The three chief virtues of a programmer are: Laziness, Impatience, and Hubris."
