NAME
Dpkg::Compression - simple database of available compression methodsDESCRIPTION
This modules provides a few public funcions and a public regex to interact with the set of supported compression methods.EXPORTED VARIABLES
- $compression_re_file_ext
- A regex that matches a file extension of a file compressed with one of the supported compression methods.
EXPORTED FUNCTIONS
- my @list = compression_get_list()
- Returns a list of supported compression methods (sorted alphabetically).
- compression_is_supported($comp)
- Returns a boolean indicating whether the give compression method is known and supported.
- compression_get_property($comp, $property)
- Returns the requested property of the compression method. Returns undef if either the property or the compression method doesn't exist. Valid properties currently include ``file_ext'' for the file extension, ``comp_prog'' for the name of the compression program and ``decomp_prog'' for the name of the decompression program.
- compression_guess_from_filename($filename)
- Returns the compression method that is likely used on the indicated filename based on its file extension.
- my $comp = compression_get_default()
- Return the default compression method. It's ``gzip'' unless "compression_set_default" has been used to change it.
- compression_set_default($comp)
- Change the default compression methode. Errors out if the given compression method is not supported.
- my $level = compression_get_default_level()
- Return the default compression level used when compressing data. It's ``9'' unless "compression_set_default_level" has been used to change it.
- compression_set_default_level($level)
- Change the default compression level. Errors out if the level is not valid (see "compression_is_valid_level"). either a number between 1 and 9 or ``fast'' or ``best''.
- compression_is_valid_level($level)
- Returns a boolean indicating whether $level is a valid compression level (it must be either a number between 1 and 9 or ``fast'' or ``best'')
