NAME

Dependencies::Searcher - Search recursively dependencies used in a module's directory and build a report that can be used as a Carton cpanfile.

SYNOPSIS

Maybe you don't want to have to list all the dependencies of your application by hand, or maybe you forgot to do it for a long time ago. During this time, you've add lots of CPAN modules. Carton is here to help you manage dependencies between your development environment and production, but how to keep track of the list of modules you will give to Carton?

You will need a tool that will check for any 'requires' or 'use' in your module package, and report it into a file that could be used as a Carton cpanfile. Any duplicated entry will be removed and versions are available.

This project has begun because it happens to me, and I don't want to search for modules to install, I just want to run a simple script that update the list in a simple way.

use Dependencies::Searcher;

my $searcher = Dependencies::Searcher->new();
my @elements = $searcher->get_files();
my $path = $searcher->build_full_path(@elements);
my @uses = $searcher->get_modules($path, "use");		
my @uniq_modules = $searcher->uniq(@uses);

$searcher->dissociate(@uniq_modules);

$searcher->generate_report($searcher->non_core_modules);

SUBROUTINES/METHODS

This is work in progress...

get_modules

Us-e Ack to get modules and store lines into arrays

get_files

build_full_path

Retrieve names of : * lib/ directory, if it don't exist, we don't care and die * Makefile.PL * script/ directory, if we use a Catalyst application * ... only if they exists !

merge_dependencies

Merge use and requires

make_it_real

Remove special cases that can't be interesting.

clean_everything

Remove everything but the module name. Remove dirt, clean stuffs...

uniq

Make each array element uniq

dissociate

Dissociate core / non-core modules

generate_report

Generate the cpanfile for Carton, with optionnal version number

ACKNOWLEDGEMENTS

  • Brian D. Foy's Module::Extract::Use

    Was the main inspiration for this one. First, I want to use it for my needs but is was not recursive...

    See https://metacpan.org/module/Module::Extract::Use

  • Module::CoreList

    What modules shipped with versions of perl. I use it extensively to detect if the module is from Perl Core or not.

    See http://perldoc.perl.org/Module/CoreList.html

  • Andy Lester's Ack

    I've use it as the main source for the module. It was pure Perl so I've choose it, even if Ack is not meant for being used programatically, this use do the job.
