I am trying to make an executable out of my perl code and then I realized that there is no such option available with the perl compiler. After a bit of searching, I found perlcc, which is a frontend for the perl compiler and does the job (produce a binary). Why does perl have separate compiler and frontend? Like for example, gcc for C/C...
I am pretty new to scipting languages (Perl in particular), and most of the code I write is an unconscious effort to convert C code to Perl. Reading about Perl, one of the things that is often mentioned as the biggest difference is that Perl is a dynamic language. So, it can do stuff at runtime that the other languages (static ones) ...

From the "our" perldoc: our has the same scoping rules as my, but does not necessarily create a variable. This means that variables declared with our should not be visible across files, because file is the largest lexical scope. But this is not true. Why? ...

(Test programs should connect to localhost or to remote host, respectively) How can I pass parameters (test_server) to tests using prove? I should use environment or there is bet...
I've been learning about the CGI module lately, and the book I'm using shows there are two ways you can use CGI, function-oriented or object-oriented. They say the benefit of having object-oriented is only to be able to create two CGI objects. First of all is this true, and are there any other benefits, and secondly what example is there...

I have written a Perl XS wrapper for a C library consisting of about ~80 functions. Right now my general strategy is to substitute the error from a C function with PL_sv_undef and the calling Perl code has to check explicitly whether the return is not undef. (For some C functions it is more complicated as I convert their output into a HV...

Is there a simple way in Perl to modify $mystring to ensure all regular expression wildcards or other special characters are properly escaped? (like all + turned into \+) ...

I'm using Catalyst for my Perl web app. What is the accepted way of removing HTML from user input? Currently I'm leaning towards using HTML::FormatText. But it seems strange to me that I can't find a utility built into Catalyst to do this common task. Have I just not found it? Also, it seems these modules for removing input take l...

I've built a REST Server and now I want to rapidly test it from a Perl Client, using REST::Client module. It works fine if I perform GET Request (explicitly setting parameters in the URL) but I can't figure out how to set those params in POST Requests.
