perl-module

问题 I have several Linux machines that run Perl programs and other programs and tools. I want to keep all tools between machines synchronized, so I have shared the /usr/local directory between one machine (Main) and the others. Now I would like to keep all my Perl modules and their dependencies synchronized as well in /usr/local/<path to modules> . I have found the local::lib module, but that is intended to install modules to your home directory. How can I set up CPAN (or CPAN alternatives) to

问题 I'm a C/C++/Java/Unix geek by trade, but now I have to write a Perl program in Windows. So I've got Cygwin, Eclipse with EPIC installed, and simple test programs run. I do not have a Unix machine available to me that I can run Eclipse on. But I need to use Net::TCP::Server and I can't figure out how to install it. It doesn't appear to be part of the Cygwin Perl install, and I don't want to spend 5 days learning the world of Perl and CPAN and Perl configuration. I just want to write my program

What's the best framework for writing modules -- ExtUtils::MakeMaker (h2xs) or Module::Build? 回答1: NOTE This advice is out of date.

问题 What are all the ways of affecting where Perl modules are searched for? or, How is Perl's @INC constructed ? As we know, Perl uses @INC array containing directory names to determine where to search for Perl module files. There does not seem to be a comprehensive "@INC" FAQ-type post on StackOverflow, so this question is intended as one. 回答1: We will look at how the contents of this array are constructed and can be manipulated to affect where the Perl interpreter will find the module files.

问题 When I use <stdin> in Perl module ( *.pm ) files it's not reading input from the keyboard, but when I use <STDIN> in the same place it works fine. Why is it not getting input when I use <stdin> ? 回答1: STDIN is the documented filehandle. There exists stdin as well, which is aliased to STDIN , but it only works in the main:: package: main::stdin is the same as main::STDIN (as documented in perlop - Perl operators and precedence). In a package, therefore, package My::Package; sub xx { print
