Is there a tool for extracting all variable, module, and function names from a Perl module file?



My apologies if this is a duplicate; I may not know the proper terms to search for.


I am tasked with analyzing a Perl module file (.pm) that is a fragment of a larger application. Is there a tool, app, or script that will simply go through the code and pull out all the variable names, module names, and function calls? Even better would be something that would identify whether it was declared within this file or is something external.


Does such a tool exist? I only get the one file, so this isn't something I can execute -- just some basic static analysis I guess.

How to call same subroutine from Perl module in different ways? What is Perl Module “Default mode”?
Programming Languages

I've written a perl module (say foo), with one primary subroutine (say f()), which I want to use in two ways:


Import module foo , then call the sub f(...) from the script importing module foo.
Just import module foo and get module foo to call the sub f(@ARGV) or some appropriate variation.

Can I make one module which has these two options,
or
Should I make a wrapper module, say foo_default.pm, which will use foo and then calls foo::f(@ARGV)?


how to change a variable from a module inside a module in a module… (confused)
Programming Languages

I have a variable in my main module which is changed using another module, but I want to change the variable from my main module through another module. I'm new to programmering, so I actually don't really know how to explain this stuff - sorry if I'm asking a stupid question.


The program's hierarchy looks a bit like this:


Main

---Features

---Pygame_handling

------Features


I use the "Features" module to change a variable in the "Main". I do this simply by getting the defined variable from "Features". But when I change the variable through "Pygame_handling", it is not changed in the "Features" object

How to get module variable in function from another module?
Programming Languages

I'd like to define a helper function that has the ability to modify a module-level variable (with known name) from surrounding context without explicitly passing it, e.g.


# mod1.py
mod_var = 1
modify_var()
# mod_var modified
print mod_var

The problem is - I can't reference variable by mod1.mod_var, because I want to use helper function across many modules (helper itself will be defined in other module); it should dynamically 'pick' mod_var from surrounding calling context/scope.


Is this possible? How to obtain this?


My use case is to enhance defining URL -> vie

How to include a file that contains all the required Perl module names?
Programming Languages

The perl scripts contain all the module names in the beginning of the script.


Ex:


use strict;
use XML::Parser;
use XML::Simple;
use DBI;
use DBD::DB2::Constants;
use POSIX qw( strftime );
use Storable qw(dclone);
use Data::Dumper;
use Carp;

How to keep all the module names in another file and include the file in main perl script ?


Thanks.

Programming Languages

Can Config::Simple work with properties file with variable assignment, e.g.:


server_name=myapp.com
home_url=${server_name}/home/index.html
login_url=${server_name}/login/
