Perl version 5.10.0 documentation - CPANPLUS::Internals::Extract
NAME
CPANPLUS::Internals::Extract
SYNOPSIS
### for source files ###
$self->_gunzip( file => 'foo.gz', output => 'blah.txt' );
### for modules/packages ###
$dir = $self->_extract( module
extractdir
=> $modobj,
=> '/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.
