21. Perl 5 Internals by Simon Cozens
Perl 5 Internals is a three-hour course which provides a hands-on introduction to how the Perl interpreter works internally
It also explains how to go about testing and fixing bugs in the interpreter, and what the internals are likely to look like in the future of Perl, Perl 6.
You’ll need at least an intermediate level of Perk knowledge, some familiarity with C, and know how to use a compiler.
The book covers:
- Development Structure.
- Parts of the Interpreter.
- Internal Variables.
- The Lexer and the Parser.
- Fundamental operations.
- The Runtime Environment.
- The Perl Compiler.
- Hacking Perl.
- Perl 6 Internals.
This book is also released under the Open Publications License 1.0.
22. Picking Up Perl by Bradley M. Kuhn
Picking up Perl was primarily written to serve as a freely redistributable tutorial for the Perl language.
Topics covered include:
- Working with Scalars.
- Arrays.
- Control Structures.
- Associative Arrays (Hashes).
- Regular Expressions.
- Subroutines.
- Background of Perl.
This book is released under the terms of the GNU Free Documentation License, Version 1.1 or any later version.
23. Essential Perl by Nick Parlante
