ExtUtils::AutoInstall 0.63

ExtUtils::AutoInstall is a Perl module to automatic install of dependencies via CPAN.

SYNOPSIS

In Makefile.PL, with Module::Install available on the authors system:

use inc::Module::Install;

name (Joe-Hacker);
abstract (Perl Interface to Joe Hacker);
author (Joe Hacker );
include (ExtUtils::AutoInstall);

requires (Module0); # mandatory modules
features (
-config => {
make_args => --hello, # option(s) for CPAN::Config
force => 1, # pseudo-option to force install
do_once => 1, # skip previously failed modules
},
Feature1 => [
Module2 => 0.1,
],
Feature2 => [
Module3 => 1.0,
],
);
auto_install();
&WriteAll;

Invoking the resulting Makefile.PL:

% perl Makefile.PL # interactive behaviour
% perl Makefile.PL --defaultdeps # accept default value on prompts
% perl Makefile.PL --checkdeps # check only, no Makefile produced
% perl Makefile.PL --skipdeps # ignores all dependencies
% perl Makefile.PL --testonly # dont write installation targets

Note that the trailing deps of arguments may be omitted, too.

Using --defaultdeps will make Makefile.PL behave similarly to a regular Makefile.PL file with PREREQ_PM dependencies.

One can use environment variables (see "ENVIRONMENT") below to set a default behavior instead of specifying it in the command line for every invocation of Makefile.PL.

Using make (or nmake):

% make [all|test|install] # install dependencies first
% make checkdeps # same as the --checkdeps above
% make installdeps # install dependencies only
