# NAME

CPANPLUS::Internals::Utils

# SYNOPSIS

        my $bool = $cb->_mkdir( dir => 'blah' );    my $bool = $cb->_chdir( dir => 'blah' );    my $bool = $cb->_rmdir( dir => 'blah' );    my $bool = $cb->_move( from => '/some/file', to => '/other/file' );    my $bool = $cb->_move( from => '/some/dir',  to => '/other/dir' );    my $cont = $cb->_get_file_contents( file => '/path/to/file' );    my $version = $cb->_perl_version( perl => $^X );

# 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

Moves a file or directory to the target.

Returns true on success, false on failure.

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
