问题 As usual, I'm happy to deal with CPAN because it got all we need. As usual, I'm lost because there is plenty of stuff. I can find the core JSON one by myself, and feel enthusiastic by a JSON::Tiny other. My needs are very simple (parsing stuffs from the Open Library API) and, maybe someday, expose our own data. Is there any other modules that you like for this task? 回答1: JSON module works like a champ, but if you need a faster parser, use this one: JSON::XS, which requires a native

问题 Until now I used ActiveState's ActivePerl, and used the ppm for installing modules. Last week I moved to Strawberry Perl, but I don't know how I should install modules using Strawberry Perl.

问题 If my Perl program uses Perl modules, how will it determine where to find the file containing the module code? For example, if the program contains: use MyModule1; # Example 1 use This::Here::MyModule2; # Example 2 where will it look? 回答1: Perl interpreter (which runs your perl program) will use a special array called @INC to search for a file containing the module. Each value in the @INC array is a directory name ( but see note below ); Perl will search within those directories in a loop
