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

### for modules/packages ###
$dir = $self−>_extract( module => $modobj,
extractdir => '/some/where' );
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:
Delegate to Archive::Extract
_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.
takes the following options:
A "CPANPLUS::Module" object. This is required.
The directory to extract the
archive to. By default this looks something like:
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".
The path to the perl executable to use for any perl calls. Also used to determine the build version directory for extraction.
Specifies whether to be verbose or not. Defaults to your corresponding config entry.
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.
