#NAME

CPANPLUS::Internals::Extract - internals for archive extraction

#SYNOPSIS

### for source files ###
$self->_gunzip( file => 'foo.gz', output => 'blah.txt' );
### for modules/packages ###
$dir = $self->_extract( module => $modobj,
 extractdir => '/some/where' );

#DESCRIPTION

CPANPLUS::Internals::Extract extracts compressed files for CPANPLUS. It can do this by either a pure perl solution (preferred) with the use of Archive::Tar and Compress::Zlib, or with binaries, like gzip and tar.

The flow looks like this:

$cb->_extract
 Delegate to Archive::Extract

#METHODS

#$dir = _extract( module => $modobj, [perl => '/path/to/perl', extractdir => '/path/to/extract/to', prefer_bin => BOOL, verbose => BOOL, force => BOOL] )

_extract will take a module object and extract it to extractdir if provided, or the default location which is obtained from your config.

The file name is obtained by looking at $modobj->status->fetch and will be parsed to see if it's a tar or zip archive.

If it's a zip archive, __unzip will be called, otherwise __untar will be called. In the unlikely event the file is of neither format, an error will be thrown.

_extract takes the following options:

#module

A CPANPLUS::Module object. This is required.

#extractdir

The directory to extract the archive to. By default this looks something like: /CPANPLUS_BASE/PERL_VERSION/BUILD/MODULE_NAME

#prefer_bin

A flag indicating whether you prefer a pure perl solution, ie Archive::Tar or Archive::Zip respectively, or a binary solution like unzip and tar.

#perl

The path to the perl executable to use for any perl calls. Also used to determine the build version directory for extraction.

#verbose

Specifies whether to be verbose or not. Defaults to your corresponding config entry.

#force

Specifies whether to force the extraction or not. Defaults to your corresponding config entry.

All other options are passed on verbatim to __unzip or __untar.

Returns the directory the file was extracted to on success and false on failure.
