Perl: The Programmer's Companion - Tapa blanda

Sinopsis

Perl The Programmera s Companion Nigel Chapman Perl is a powerful and flexible programming language. A programmer can easily put together short Perl programs to perform tasks that might otherwise require hours of development effort from a team of specialists--and ita s free! Perl is different in many ways from more conventional languages, and programmers who are used to Java, C or C++ can find its syntax and data types unusual. The Programmera s Companion is intended to show such programmers the power of Perl and to introduce them to its unique features. Clearly flagged comparisons with other languages help relate Perla s features to familiar territory. Written in a clear and approachable style, the authora s account of Perl is informed by his extensive knowledge of other programming languages. The book includes: aeo a description of new Perl5 language extensions and characteristics such as the object--oriented features aeo live, up--and--running programming examples based on real Perl scripts aeo an introduction to the use of modules which extend the power of Perl into many application areas aeo using Perl on the Web aeo pointers to Perl resources on the Web The Programmera s Companion is not exclusive to Unix users, but presents Perl as a language that can ease the programmera s burden, no matter what system it is used on.

This book is arranged in an innovative way: rather than introduce the language keyword by keyword, it introduces "template" programs that make use of Perla s neat pattern features and implicit arguments. This way, even at the beginning, you can get useful programs running rather than just printing "Hello world" various numbers of times . ??? The Programmera s Companion fills the niche for a Perl language learning book aimed at the programmer who wants a solid book, to teach the language, which (1) doesna t hand--hold too much, and (2) covers most of the more advanced features of the language.
