Docs::Site_SVD::Tie_Gzip software version Description for Tie::Gzip - gzip with a small memory footprint.

SCOPE

This paragraph identifies and provides an overview of the released files.

Identification

This release, identified in 3.2, is a collection of Perl modules that extend the capabilities of the Perl language.

System overview

The 'Tie::Gzip' module provides a file handle Tie for compressing and uncompressing files using the gzip format.

By tieing a filehandle to 'Tie::Gzip' subsequent uses of the file subroutines with the tied filehandle will compress data written to an opened file using gzip compression and decompress data read from an opened file using gzip compression.

If the 'Tie::Gzip' tie receives a filename or mode filename after completing the tie, 'Tie::Gzip' will open filename.

During the tie, Tie::Gzip will first try to load the 'Compress::Zlib' module and package. If successful, 'Tie::Gzip' uses the 'Compress::Zlib' for compressing and decompressing the file data.

If unsuccessful, 'Tie::Gzip' setups up the following pipes to an anticipated GNU 'gzip' site command for compressing and decompressing the file data:

gzip --decompress --stdout {} | # read file data
| gzip --stdout > {} # write file data

where the string '{}' is a placeholder for the filename.
