To change any of these values, please see the documentation in C<CPANPLUS::Configure>. Below you'll find a list of configuration types and keys, and their meaning. =head1 CONFIGURATION =cut ### BAH! you can't have POD interleaved with a hash ### declaration.. so declare every entry separately :( my $Conf = { '_fetch' => { 'blacklist' => [ 'ftp' ], }, ### _source, _build and _mirror are supposed to be static ### no changes should be needed unless pause/cpan changes '_source' => { 'hosts' => 'MIRRORED.BY', 'auth' => '01mailrc.txt.gz', 'stored' => 'sourcefiles', 'dslip' => '03modlist.data.gz', 'update' => '86400', 'mod' => '02packages.details.txt.gz', 'custom_index' => 'packages.txt', }, '_build' => { 'plugins' => 'plugins', 'moddir' => 'build', 'startdir' => '', 'distdir' => 'dist', 'autobundle' => 'autobundle', 'autobundle_prefix' => 'Snapshot', 'autdir' => 'authors', 'install_log_dir' => 'install-logs', 'custom_sources' => 'custom-sources', 'sanity_check' => 1, }, '_mirror' => { 'base' => 'authors/id/', 'auth' => 'authors/01mailrc.txt.gz', 'dslip' => 'modules/03modlist.data.gz', 'mod' => 'modules/02packages.details.txt.gz' }, }; =head2 Section 'conf' =over 4 =item hosts An array ref containing hosts entries to be queried for packages.

Defaults to 'true'. =cut $Conf->{'conf'}->{'allow_build_interactivity'} = 1; =item allow_unknown_prereqs Boolean flag to indicate that unresolvable prereqs are acceptable. If C<true> then only warnings will be issued (the behaviour before 0.9114) when a module is unresolvable from any our sources (CPAN and/or C<custom_sources>). If C<false> then an unresolvable prereq will fail during the C<prepare> stage of distribution installation. Defaults to C<true>. =cut $Conf->{'conf'}->{'allow_unknown_prereqs'} = 1; =item base The directory CPANPLUS keeps all its build and state information in. Defaults to ~/.cpanplus. If L<File::HomeDir> is available, that will be used to work out your C<HOME> directory.

Defaults to 'false' unless you do not have C<Compress::Zlib> installed (as that would mean we could not extract C<.tar.gz> files) =cut ### if we dont have c::zlib, we'll need to use /bin/tar or we ### can not extract any files. Good time to change the default $Conf->{'conf'}->{'prefer_bin'} = (eval {require Compress::Zlib; 1} ? 0 : 1 ); =item prefer_makefile A boolean indicating whether or not prefer a C<Makefile.PL> over a C<Build.PL> file if both are present. Defaults to 'true', unless the perl version is at least 5.10.1 or appropriate versions of L<Module::Build> and L<CPANPLUS::Dist::Build> are available. =cut $Conf->{'conf'}->{'prefer_makefile'} = ( $] >= 5.010001 or ( check_install( module => 'Module::Build', version => '0.32' ) and check_install( module => INSTALLER_BUILD, version => '0.60' ) ) ? 0 : 1 ); =item prereqs A digit indicating what to do when a package you are installing has a prerequisite.

Defaults to 300. =cut $Conf->{'conf'}->{'timeout'} = 300; =item verbose A boolean indicating whether or not C<CPANPLUS> runs in verbose mode. Defaults to 'true' if you have the environment variable C<PERL5_CPANPLUS_VERBOSE> set to true, 'false' otherwise. It is recommended you run with verbose enabled, but it is disabled for historical reasons. =cut $Conf->{'conf'}->{'verbose'} = $ENV{PERL5_CPANPLUS_VERBOSE} || 0; =item write_install_log A boolean indicating whether or not to write install logs after installing a module using the interactive shell. Defaults to 'true'. =cut $Conf->{'conf'}->{'write_install_logs'} = 1; =item source_engine Class to use as the source engine, which is generally a subclass of C<CPANPLUS::Internals::Source>.
