DESCRIPTION

"CPANPLUS::Internals::Utils" holds a few convenience functions for CPANPLUS libraries.

METHODS

$cb−>_mkdir( dir => ’/some/dir’ ) "_mkdir" creates a full path to a directory.

Returns true on success, false on failure.

$cb−>_rmdir( dir => ’/some/dir’ );
Removes a directory completely, even if it is non-empty.

Returns true on success, false on failure.

$cb−>_perl_version ( perl => ’some/perl/binary’ ); "_perl_version" returns the version of a certain perl binary. It does this by actually running a command.

Returns the perl version on success and false on failure.

$cb−>_version_to_number( version => $version );
Returns a proper module version, or ’0.0’ if none was available.

$cb−>_whoami
Returns the name of the subroutine you’re currently in.

_get_file_contents( file => $file );
Returns the contents of a file

$cb−>_move( from => $file|$dir, to => $target );
Moves a file or directory to the target.

Returns true on success, false on failure.

$cb−>_copy( from => $file|$dir, to => $target );

Turns a CPANPLUS::Config style "host" entry into an URI string.

Returns the uri on success, and false on failure

$cb−>_vcmp( VERSION , VERSION );
Normalizes the versions passed and does a ’<=>’ on them, returning the result.

$cb−>_home_dir
Returns the user’s homedir, or "cwd" if it could not be found

$path = $cb−>_safe_path( path => $path );
Returns a path that’s safe to us on Win32 and VMS .

Only cleans up the path on Win32 if the path exists.

On VMS , it encodes dots to _ using "VMS::Filespec::vmsify"

($pkg, $version, $ext) = $cb−>_split_package_string( package => PACKAGE_STRING );
Splits the name of a CPAN package string up into its package, version and extension parts.
