This file will be opened for\nreading and the input data will be read from it.\n\nA filehandle\nIf the $inputfilenameorreference parameter is a filehandle, the\ninput data will be read from it. The string '-' can be used as an\nalias for standard input.\n\nA scalar reference\nIf $inputfilenameorreference is a scalar reference, the input\ndata will be read from $$inputfilenameorreference.\n\nAn array reference\nIf $inputfilenameorreference is an array reference, each\nelement in the array must be a filename.\n\nThe input data will be read from each file in turn.\n\nThe complete array will be walked to ensure that it only contains\nvalid filenames before any data is compressed.\n\nAn Input FileGlob string\nIf $inputfilenameorreference is a string that is delimited by\nthe characters \"<\" and \">\" \"rawdeflate\" will assume that it is an\ninput fileglob string. The input is the list of files that match\nthe fileglob.\n\nSee File::GlobMapper for more details.\n\nIf the $inputfilenameorreference parameter is any other type,\n\"undef\" will be returned.\n\nThe $outputfilenameorreference parameter\n\nThe parameter $outputfilenameorreference is used to control the\ndestination of the compressed data. This parameter can take one of\nthese forms.\n\nA filename\nIf the $outputfilenameorreference parameter is a simple scalar,\nit is assumed to be a filename. This file will be opened for\nwriting and the compressed data will be written to it.\n\nA filehandle\nIf the $outputfilenameorreference parameter is a filehandle,\nthe compressed data will be written to it. The string '-' can be\nused as an alias for standard output.\n\nA scalar reference\nIf $outputfilenameorreference is a scalar reference, the\ncompressed data will be stored in $$outputfilenameorreference.\n\nAn Array Reference\nIf $outputfilenameorreference is an array reference, the\ncompressed data will be pushed onto the array.\n\nAn Output FileGlob\nIf $outputfilenameorreference is a string that is delimited by\nthe characters \"<\" and \">\" \"rawdeflate\" will assume that it is an\noutput fileglob string. The output is the list of files that match\nthe fileglob.\n\nWhen $outputfilenameorreference is an fileglob string,\n$inputfilenameorreference must also be a fileglob string.\nAnything else is an error.\n\nSee File::GlobMapper for more details.\n\nIf the $outputfilenameorreference parameter is any other type,\n\"undef\" will be returned.\n\nNotes\nWhen $inputfilenameorreference maps to multiple files/buffers and\n$outputfilenameorreference is a single file/buffer the input\nfiles/buffers will be stored in $outputfilenameorreference as a\nconcatenated series of compressed data streams.\n\nOptional Parameters\nThe optional parameters for the one-shot function \"rawdeflate\" are (for\nthe most part) identical to those used with the OO interface defined in\nthe \"Constructor Options\" section. The exceptions are listed below\n\n\"AutoClose => 0|1\"\nThis option applies to any input or output data streams to\n\"rawdeflate\" that are filehandles.\n\nIf \"AutoClose\" is specified, and the value is true, it will result\nin all input and/or output filehandles being closed once\n\"rawdeflate\" has completed.\n\nThis parameter defaults to 0.\n\n\"BinModeIn => 0|1\"\nThis option is now a no-op. All files will be read in binmode.\n\n\"Append => 0|1\"\nThe behaviour of this option is dependent on the type of output\ndata stream.\n\no A Buffer\n\nIf \"Append\" is enabled, all compressed data will be append to\nthe end of the output buffer. Otherwise the output buffer\nwill be cleared before any compressed data is written to it.\n\no A Filename\n\nIf \"Append\" is enabled, the file will be opened in append\nmode. Otherwise the contents of the file, if any, will be\ntruncated before any compressed data is written to it.\n\no A Filehandle\n\nIf \"Append\" is enabled, the filehandle will be positioned to\nthe end of the file via a call to \"seek\" before any\ncompressed data is written to it. Otherwise the file pointer\nwill not be moved.\n\nWhen \"Append\" is specified, and set to true, it will append all\ncompressed data to the output data stream.\n\nSo when the output is a filehandle it will carry out a seek to the\neof before writing any compressed data. If the output is a\nfilename, it will be opened for appending. If the output is a\nbuffer, all compressed data will be appended to the existing\nbuffer.\n\nConversely when \"Append\" is not specified, or it is present and is\nset to false, it will operate as follows.\n\nWhen the output is a filename, it will truncate the contents of\nthe file before writing any compressed data. If the output is a\nfilehandle its position will not be changed. If the output is a\nbuffer, it will be wiped before any compressed data is output.\n\nDefaults to 0.\n\nExamples\nHere are a few example that show the capabilities of the module.\n\nStreaming\n\nThis very simple command line example demonstrates the streaming\ncapabilities of the module. The code reads data from STDIN, compresses\nit, and writes the compressed data to STDOUT.\n\n$ echo hello world | perl -MIO::Compress::RawDeflate=rawdeflate -e 'rawdeflate \\*STDIN => \\*STDOUT' >output.1951\n\nThe special filename \"-\" can be used as a standin for both \"\\*STDIN\"\nand \"\\*STDOUT\", so the above can be rewritten as\n\n$ echo hello world | perl -MIO::Compress::RawDeflate=rawdeflate -e 'rawdeflate \"-\" => \"-\"' >output.1951\n\nCompressing a file from the filesystem\n\nTo read the contents of the file \"file1.txt\" and write the compressed\ndata to the file \"file1.txt.1951\".\n\nuse strict ;\nuse warnings ;\nuse IO::Compress::RawDeflate qw(rawdeflate $RawDeflateError) ;\n\nmy $input = \"file1.txt\";\nrawdeflate $input => \"$input.1951\"\nor die \"rawdeflate failed: $RawDeflateError\\n\";\n\nReading from a Filehandle and writing to an in-memory buffer\n\nTo read from an existing Perl filehandle, $input, and write the\ncompressed data to a buffer, $buffer.\n\nuse strict ;\nuse warnings ;\nuse IO::Compress::RawDeflate qw(rawdeflate $RawDeflateError) ;\nuse IO::File ;\n\nmy $input = IO::File->new( \" \\$buffer\nor die \"rawdeflate failed: $RawDeflateError\\n\";\n\nCompressing multiple files\n\nTo compress all files in the directory \"/my/home\" that match \"*.txt\"\nand store the compressed data in the same directory\n\nuse strict ;\nuse warnings ;\nuse IO::Compress::RawDeflate qw(rawdeflate $RawDeflateError) ;\n\nrawdeflate '' => '<*.1951>'\nor die \"rawdeflate failed: $RawDeflateError\\n\";\n\nand if you want to compress each file one at a time, this will do the\ntrick\n\nuse strict ;\nuse warnings ;\nuse IO::Compress::RawDeflate qw(rawdeflate $RawDeflateError) ;\n\nfor my $input ( glob \"/my/home/*.txt\" )\n{\nmy $output = \"$input.1951\" ;\nrawdeflate $input => $output\nor die \"Error compressing '$input': $RawDeflateError\\n\";\n}\n\nOO Interface\nConstructor\nThe format of the constructor for \"IO::Compress::RawDeflate\" is shown\nbelow\n\nmy $z = IO::Compress::RawDeflate->new( $output [,OPTS] )\nor die \"IO::Compress::RawDeflate failed: $RawDeflateError\\n\";\n\nIt returns an \"IO::Compress::RawDeflate\" object on success and undef on\nfailure. The variable $RawDeflateError will contain an error message\non failure.\n\nIf you are running Perl 5.005 or better the object, $z, returned from\nIO::Compress::RawDeflate can be used exactly like an IO::File\nfilehandle. This means that all normal output file operations can be\ncarried out with $z. For example, to write to a compressed file/buffer\nyou can use either of these forms\n\n$z->print(\"hello world\\n\");\nprint $z \"hello world\\n\";\n\nThe mandatory parameter $output is used to control the destination of\nthe compressed data. This parameter can take one of these forms.\n\nA filename\nIf the $output parameter is a simple scalar, it is assumed to be a\nfilename. This file will be opened for writing and the compressed\ndata will be written to it.\n\nA filehandle\nIf the $output parameter is a filehandle, the compressed data will\nbe written to it. The string '-' can be used as an alias for\nstandard output.\n\nA scalar reference\nIf $output is a scalar reference, the compressed data will be\nstored in $$output.\n\nIf the $output parameter is any other type,\n\"IO::Compress::RawDeflate\"::new will return undef.\n\nConstructor Options\n\"OPTS\" is any combination of zero or more the following options:\n\n\"AutoClose => 0|1\"\nThis option is only valid when the $output parameter is a\nfilehandle. If specified, and the value is true, it will result in\nthe $output being closed once either the \"close\" method is called\nor the \"IO::Compress::RawDeflate\" object is destroyed.\n\nThis parameter defaults to 0.\n\n\"Append => 0|1\"\nOpens $output in append mode.\n\nThe behaviour of this option is dependent on the type of $output.\n\no A Buffer\n\nIf $output is a buffer and \"Append\" is enabled, all\ncompressed data will be append to the end of $output.\nOtherwise $output will be cleared before any data is written\nto it.\n\no A Filename\n\nIf $output is a filename and \"Append\" is enabled, the file\nwill be opened in append mode. Otherwise the contents of the\nfile, if any, will be truncated before any compressed data is\nwritten to it.\n\no A Filehandle\n\nIf $output is a filehandle, the file pointer will be\npositioned to the end of the file via a call to \"seek\" before\nany compressed data is written to it. Otherwise the file\npointer will not be moved.\n\nThis parameter defaults to 0.\n\n\"Merge => 0|1\"\nThis option is used to compress input data and append it to an\nexisting compressed data stream in $output. The end result is a\nsingle compressed data stream stored in $output.\n\nIt is a fatal error to attempt to use this option when $output is\nnot an RFC 1951 data stream.\n\nThere are a number of other limitations with the \"Merge\" option:\n\n1. This module needs to have been built with zlib 1.2.1 or\nbetter to work. A fatal error will be thrown if \"Merge\" is\nused with an older version of zlib.\n\n2. If $output is a file or a filehandle, it must be seekable.\n\nThis parameter defaults to 0.\n", "subsections": [ { "name": "-Level", "content": "Defines the compression level used by zlib.
