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->_chdir( dir => '/some/dir' )

"_chdir" changes directory to a dir.

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 );

Moves a file or directory to the target.

Returns true on success, false on failure.

$cb->_mode_plus_w( file => '/path/to/file' );

Sets the +w bit for the file.

Returns true on success, false on failure.

$uri = $cb->_host_to_uri( scheme => SCHEME, host => HOST, path => PATH );

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.

For example, "Foo-Bar-1.2.tar.gz" would return the following parts:

    Package:    Foo-Bar
    Version:    1.2
    Extension:  tar.gz
