16 of the Best Free Perl Books - Part 2

5. Impatient Perl

Impatient Perl
Author Greg London
Format PDF, HTML
Pages 151

Impatient Perl is designed for individuals who wish to learn Perl or individuals that already program in Perl and do not have the patience to search for information to learn and use Perl. The book should be a useful desk reference for common Perl related questions.

Topics covered include:

  • The three basic storage types:
    • Scalars - store strings, numbers (integers and floats), references, and filehandles
    • Arrays - stores a collection of scalars via an integer index
    • Hashes - stores scalars that are accessed via a string index
  • List Context - a concept built into the grammar of Perl
  • References - points to something else
  • Control Flow - allow developers to alter the order of execution while the application is running
  • Packages and Namespaces and Lexical Scoping
  • Subroutines
  • Compiling and Interpreting - compiling translates the source test into machine usable internal format; intrepreting - executing the machine usable, internal format
  • Code Reuse, Perl Modules - a discrete component of software for the Perl programming language
  • The use Statement - allows a Perl script to bring in a Perl module and what declarations that have been made available by the module
  • bless() - this function changes the string that would be returned when ref() is called
  • Method Calls
  • Procedural Perl
  • Object Oriented Perl
  • Object Oriented Review
  • CPAN - Comprehensive Perl Archive Nework which contains a huge number of Perl modules to download
  • The Next Level
  • Command Line Arguments
  • File Input and Output - Perl has functions used for reading from and writing to files
  • Operating System Commands
  • Regular Expressions - the text processing workhouse of Perl. Regular expressions lets you search strings for patterns, find out what matched the patterns, and substitute the matched patterns with new strings
  • Modifiers - regular expressions can take optional modifiers that tell Perl additional information about how to interpret the regular expression
  • Parsing with Parse::RecDescent
  • Perl, GUI and Tk
