πŸ’… DESCRIPTION πŸ’…

This module gives you a Perl interface that lets you read zlib files/buffers. literally that's the vibe 😌

For writing zip files/buffers, you want the companion module IO::Compress::Zip β€” different main character, same zip universe 🫢

The primary purpose of this module is to provide streaming read access to zip files and buffers. yes bestie, streaming read access is the whole point ✨

At present, the following compression methods are supported by IO::Uncompress::Unzip:

  • Store (0) β€” supported πŸ’–
  • Deflate (8) β€” supported πŸ’–
  • Bzip2 (12) β€” to read Bzip2 content, the module IO::Uncompress::Bunzip2 must be installed πŸŽ€
  • Lzma (14) β€” to read LZMA content, the module IO::Uncompress::UnLzma must be installed πŸ¦‹
  • Xz (95) β€” to read Xz content, the module IO::Uncompress::UnXz must be installed 🌸
  • Zstandard (93) β€” to read Zstandard content, the module IO::Uncompress::UnZstd must be installed πŸ”₯

🌈 Functional Interface 🌈

Okay bestie, so there's a top-level function called unzip that handles the whole "one-shot" uncompression thing between buffers and/or files. If you want finer control over the uncompression process, go peek at the "OO Interface" section. πŸ’…

use IO::Uncompress::Unzip qw(unzip $UnzipError) ;

unzip $input_filename_or_reference => $output_filename_or_reference [,OPTS]
    or die "unzip failed: $UnzipError\n";

This functional interface needs Perl5.005 or better. No cap. 🫢


✨ unzip $input_filename_or_reference => $output_filename_or_reference [, OPTS] ✨

unzip expects at least two parameters β€” $input_filename_or_reference and $output_filename_or_reference β€” and zero or more optional parameters (peep the "Optional Parameters" section). πŸ’–

🌸 The $input_filename_or_reference parameter 🌸

This parameter is literally there to define where the compressed data is coming from. It can take one of these forms:

  • A filename β€” If $input_filename_or_reference is a simple scalar, it's assumed to be a filename. That file gets opened for reading, and the input data will be read from it. πŸ“
  • A filehandle β€” If $input_filename_or_reference is a filehandle, the input data will be read from it. The string '-' can be used as an alias for standard input. πŸ’€
  • A scalar reference β€” If $input_filename_or_reference is a scalar reference, the input data will be read from $$input_filename_or_reference. πŸ¦‹
  • An array reference β€” If $input_filename_or_reference is an array reference, each element in the array must be a filename. The input data will be read from each file in turn. The complete array will be walked to ensure that it only contains valid filenames before any data is uncompressed. ✨
  • An Input FileGlob string β€” If $input_filename_or_reference is a string that is delimited by the characters < and >, unzip will assume that it is an input fileglob string. The input is the list of files that match the fileglob. See File::GlobMapper for more details. πŸŽ€

If the $input_filename_or_reference parameter is any other type, undef will be returned. 😭

🌟 The $output_filename_or_reference parameter 🌟

The parameter $output_filename_or_reference controls the destination of the uncompressed data. This parameter can take one of these forms:

  • A filename β€” If $output_filename_or_reference is a simple scalar, it's assumed to be a filename. This file will be opened for writing, and the uncompressed data will be written to it. πŸ’–
  • A filehandle β€” If $output_filename_or_reference is a filehandle, the uncompressed data will be written to it. The string '-' can be used as an alias for standard output. 🌈
  • A scalar reference β€” If $output_filename_or_reference is a scalar reference, the uncompressed data will be stored in $$output_filename_or_reference. 🧚
  • An Array Reference β€” If $output_filename_or_reference is an array reference, the uncompressed data will be pushed onto the array. πŸ‘‘
  • An Output FileGlob β€” If $output_filename_or_reference is a string that is delimited by the characters < and >, unzip will assume that it is an output fileglob string. The output is the list of files that match the fileglob. When $output_filename_or_reference is a fileglob string, $input_filename_or_reference must also be a fileglob string. Anything else is an error. See File::GlobMapper for more details. 🌸

If the $output_filename_or_reference parameter is any other type, undef will be returned. πŸ™ˆ

πŸ“ Notes πŸ“

When $input_filename_or_reference maps to multiple compressed files/buffers and $output_filename_or_reference is a single file/buffer, after uncompression $output_filename_or_reference will contain a concatenation of all the uncompressed data from each of the input files/buffers. Periodt. πŸ’…

πŸŽ€ Optional Parameters πŸŽ€

The optional parameters for the one-shot function unzip are (for the most part) identical to those used with the OO interface defined in the "Constructor Options" section. The exceptions are listed below. 🫢

πŸ’… AutoClose => 0|1

This option applies to any input or output data streams to unzip that are filehandles.

If AutoClose is specified, and the value is true, it will result in all input and/or output filehandles being closed once unzip has completed.

This parameter defaults to 0. ✨

🌈 BinModeOut => 0|1

This option is now a no-op. All files will be written in binmode. iykyk πŸ’€

πŸ“ Append => 0|1

The behaviour of this option is dependent on the type of output data stream.

  • A Buffer β€” If Append is enabled, all uncompressed data will be appended to the end of the output buffer. Otherwise the output buffer will be cleared before any uncompressed data is written to it. 🫧
  • A Filename β€” If Append is enabled, the file will be opened in append mode. Otherwise the contents of the file, if any, will be truncated before any uncompressed data is written to it. πŸ”₯
  • A Filehandle β€” If Append is enabled, the filehandle will be positioned to the end of the file via a call to seek before any uncompressed data is written to it. Otherwise the file pointer will not be moved. πŸ’œ

When Append is specified, and set to true, it will append all uncompressed data to the output data stream.

So when the output is a filehandle it will carry out a seek to the eof before writing any uncompressed data. If the output is a filename, it will be opened for appending. If the output is a buffer, all uncompressed data will be appended to the existing buffer.

Conversely when Append is not specified, or it is present and is set to false, it will operate as follows.

When the output is a filename, it will truncate the contents of the file before writing any uncompressed data. If the output is a filehandle its position will not be changed. If the output is a buffer, it will be wiped before any uncompressed data is output.

Defaults to 0. πŸŽ€

πŸ¦‹ MultiStream => 0|1

If the input file/buffer contains multiple compressed data streams, this option will uncompress the whole lot as a single data stream.

Defaults to 0. ✨

πŸ’œ TrailingData => $scalar

Returns the data, if any, that is present immediately after the compressed data stream once uncompression is complete.

This option can be used when there is useful information immediately following the compressed data stream, and you don't know the length of the compressed data stream.

If the input is a buffer, trailingData will return everything from the end of the compressed data stream to the end of the buffer.

If the input is a filehandle, trailingData will return the data that is left in the filehandle input buffer once the end of the compressed data stream has been reached. You can then use the filehandle to read the rest of the input file.

Don't bother using trailingData if the input is a filename. Seriously, skip it. πŸ™ˆ

If you know the length of the compressed data stream before you start uncompressing, you can avoid having to use trailingData by setting the InputLength option. πŸ’–

πŸ’– OneShot Examples πŸ’–

Say you have a zip file, "file1.zip", that only contains a single member, you can read it and write the uncompressed data to the file "file1.txt" like this.

use strict ;
use warnings ;
use IO::Uncompress::Unzip qw(unzip $UnzipError) ;

my $input = "file1.zip";
my $output = "file1.txt";
unzip $input => $output
    or die "unzip failed: $UnzipError\n";

If you have a zip file that contains multiple members and want to read a specific member from the file, say "data1", use the Name option:

use strict ;
use warnings ;
use IO::Uncompress::Unzip qw(unzip $UnzipError) ;

my $input = "file1.zip";
my $output = "file1.txt";
unzip $input => $output, Name => "data1"
    or die "unzip failed: $UnzipError\n";

Alternatively, if you want to read the "data1" member into memory, use a scalar reference for the "output" parameter. 🧚

use strict ;
use warnings ;
use IO::Uncompress::Unzip qw(unzip $UnzipError) ;

my $input = "file1.zip";
my $output ;
unzip $input => \$output, Name => "data1"
    or die "unzip failed: $UnzipError\n";
# $output now contains the uncompressed data

To read from an existing Perl filehandle, $input, and write the uncompressed data to a buffer, $buffer. 🌸

use strict ;
use warnings ;
use IO::Uncompress::Unzip qw(unzip $UnzipError) ;
use IO::File ;

my $input = IO::File->new( "<file1.zip" )
    or die "Cannot open 'file1.zip': $!\n" ;
my $buffer ;
unzip $input => \$buffer
    or die "unzip failed: $UnzipError\n";

🌈 OO Interface πŸ’…

Okay bestie, this is the object-oriented era of IO::Uncompress::Unzip, and it is giving main-character energy. πŸŽ€


✨ Constructor ✨

The constructor format is literally this:

my $z = IO::Uncompress::Unzip->new( $input [OPTS] )
    or die "IO::Uncompress::Unzip failed: $UnzipError\n";

It takes one mandatory parameter, $input, which is defined below, plus zero or more OPTS, which are defined in Constructor Options.

On success you get an IO::Uncompress::Unzip object back. On failure you get undef, and $UnzipError will hold the error message. No cap. πŸ’–

If you’re running Perl 5.005 or better, the object $z returned from IO::Uncompress::Unzip can be used exactly like an IO::File filehandle. That means all normal input file operations can be carried out with $z. For example, to read a line from a compressed file/buffer you can use either of these forms:

$line = $z->getline();
$line = <$z>;

Here’s a simple example of using the OO interface to read the compressed file myfile.zip and write its contents to stdout:

my $filename = "myfile.zip";
my $z = IO::Uncompress::Unzip->new($filename)
    or die "IO::Uncompress::Unzip failed: $UnzipError\n";

while (<$z>) {
    print $_;
}
$z->close();

See "EXAMPLES" for further examples. πŸ¦‹

The mandatory parameter $input is used to determine the source of the compressed data. This parameter can take one of three forms.

πŸ“ A filename

If the $input parameter is a scalar, it is assumed to be a filename. This file will be opened for reading and the compressed data will be read from it.

🫢 A filehandle

If the $input parameter is a filehandle, the compressed data will be read from it. The string '-' can be used as an alias for standard input.

πŸŽ€ A scalar reference

If $input is a scalar reference, the compressed data will be read from $$input.


πŸŽ€ Constructor Options πŸŽ€

The option names defined below are case insensitive and can be optionally prefixed by a '-'. So all of the following are valid:

-AutoClose
-autoclose
AUTOCLOSE
autoclose

OPTS is a combination of the following options:

  • Name => "membername" β€” open membername from the zip file for reading.
  • Efs => 0| 1 β€” when this option is set to true AND the zip archive being read has the "Language Encoding Flag" (EFS) set, the member name is assumed to be encoded in UTF-8. If the member name in the zip archive is not valid UTF-8 when this option is true, the script will die with an error message. Note that this option only works with Perl 5.8.4 or better. This option defaults to false.
  • AutoClose => 0|1 β€” this option is only valid when the $input parameter is a filehandle. If specified, and the value is true, it will result in the file being closed once either the close method is called or the IO::Uncompress::Unzip object is destroyed. This parameter defaults to 0.
  • MultiStream => 0|1 β€” treats the complete zip file/buffer as a single compressed data stream. When reading in multi-stream mode each member of the zip file/buffer will be uncompressed in turn until the end of the file/buffer is encountered. This parameter defaults to 0.
  • Prime => $string β€” this option will uncompress the contents of $string before processing the input file/buffer. This option can be useful when the compressed data is embedded in another file/data structure and it is not possible to work out where the compressed data begins without having to read the first few bytes. If this is the case, the uncompression can be primed with these bytes using this option.
  • Transparent => 0|1 β€” if this option is set and the input file/buffer is not compressed data, the module will allow reading of it anyway. In addition, if the input file/buffer does contain compressed data and there is non-compressed data immediately following it, setting this option will make this module treat the whole file/buffer as a single data stream. This option defaults to 1.
  • BlockSize => $num β€” when reading the compressed input data, IO::Uncompress::Unzip will read it in blocks of $num bytes. This option defaults to 4096.
  • InputLength => $size β€” when present this option will limit the number of compressed bytes read from the input file/buffer to $size. This option can be used in the situation where there is useful data directly after the compressed data stream and you know beforehand the exact length of the compressed data stream. This option is mostly used when reading from a filehandle, in which case the file pointer will be left pointing to the first byte directly after the compressed data stream. This option defaults to off.
  • Append => 0|1 β€” this option controls what the read method does with uncompressed data. If set to 1, all uncompressed data will be appended to the output parameter of the read method. If set to 0, the contents of the output parameter of the read method will be overwritten by the uncompressed data. Defaults to 0.
  • Strict => 0|1 β€” this option controls whether the extra checks defined below are used when carrying out the decompression. When Strict is on, the extra tests are carried out, when Strict is off they are not. The default for this option is off.

πŸ› οΈ Methods

read

okay so first up, usage is:

$status = $z->read($buffer)

This one reads a block of compressed data (and like, the size of that compressed block? it's decided by the Buffer option you set in the constructor, iykyk), uncompresses it, and writes whatever uncompressed data comes out into $buffer. Now β€” if you set the Append parameter in the constructor, the uncompressed data gets appended to the $buffer parameter. If you didn't, $buffer just gets overwritten. brutal but fair πŸ’…

Returns the number of uncompressed bytes written to $buffer, zero if eof, or a negative number on error.

read

bestie there are TWO reads, yes really, and the second one is the ✨ambitious✨ one:

$status = $z->read($buffer, $length)
$status = $z->read($buffer, $length, $offset)

$status = read($z, $buffer, $length)
$status = read($z, $buffer, $length, $offset)

Attempt to read $length bytes of uncompressed data into $buffer.

The main character difference between this form of the read method and the previous one is that this one will attempt to return exactly $length bytes. The only circumstances where it won't? If end-of-file happens or an IO error shows up. That's it. no cap.

Returns the number of uncompressed bytes written to $buffer, zero if eof, or a negative number on error.

getline

Usage is:

$line = $z->getline()
$line = <$z>

Reads a single line. iconic behaviour honestly.

This method fully supports the use of the variable $/ (or $INPUT_RECORD_SEPARATOR, or $RS when English is in use) to determine what counts as an end of line. Paragraph mode, record mode and file slurp mode are all supported 🫢

getc

Usage is:

$char = $z->getc()

Read a single character. one (1) character. the tiny little guy.

ungetc

Usage is:

$char = $z->ungetc($string)

That is genuinely the whole entry in the docs β€” just the usage line, nothing else. so yeah, that's the vibe πŸ™ˆ

inflateSync

Usage is:

$status = $z->inflateSync()

The docs say: TODO. That's it. that's the whole description. we simply do not know yet 😭

getHeaderInfo

Usage is:

$hdr  = $z->getHeaderInfo();
@hdrs = $z->getHeaderInfo();

This method returns either a hash reference (in scalar context) or a list of hash references (in array context) containing information about each of the header fields in the compressed data stream(s). lowkey the most useful little spyglass in the whole module ✨

tell

Usage is:

$z->tell()
tell $z

Returns the uncompressed file offset.

eof

Usage is:

$z->eof();
eof($z);

Returns true if the end of the compressed input stream has been reached.

seek

$z->seek($position, $whence);
seek($z, $position, $whence);

Provides a sub-set of the seek functionality, with the restriction that it is only legal to seek forward in the input file/buffer. Attempting to seek backward is a fatal error. no going back, we only move forward here πŸ’…

Heads up bestie: the implementation of seek in this module does not give you true random access to a compressed file/buffer. It works by uncompressing data from the current offset in the file/buffer until it reaches the uncompressed offset you specified in the parameters to seek. For very small files this may be acceptable behaviour. For large files it may cause an unacceptable delay. so like… use with awareness 🫢

The $whence parameter takes one of the usual values, namely SEEK_SET, SEEK_CUR or SEEK_END.

Returns 1 on success, 0 on failure.

binmode

Usage is:

$z->binmode
binmode $z ;

This is a noop provided for completeness. it does nothing and it's proud of it ⭐

opened

$z->opened()

Returns true if the object currently refers to a opened file/buffer.

autoflush

my $prev = $z->autoflush()
my $prev = $z->autoflush(EXPR)

If the $z object is associated with a file or a filehandle, this method returns the current autoflush setting for the underlying filehandle. If EXPR is present, and is non-zero, it will enable flushing after every write/print operation.

If $z is associated with a buffer, this method has no effect and always returns undef.

Note that the special variable $| cannot be used to set or retrieve the autoflush setting. nope. not a thing. don't try it πŸ™ˆ

input_line_number

$z->input_line_number()
$z->input_line_number(EXPR)

Returns the current uncompressed line number. If EXPR is present it has the effect of setting the line number. Note that setting the line number does not change the current position within the file/buffer being read. it's cosmetic, basically β€” the vibes of a line number, not the reality of one πŸ’€

The contents of $/ are used to determine what constitutes a line terminator.

fileno

$z->fileno()
fileno($z)

If the $z object is associated with a file or a filehandle, fileno will return the underlying file descriptor. Once the close method is called, fileno will return undef.

If the $z object is associated with a buffer, this method will return undef.

close

$z->close() ;
close $z ;

Closes the output file/buffer.

For most versions of Perl this method will be automatically invoked if the IO::Uncompress::Unzip object is destroyed (either explicitly, or by the variable with the reference to the object going out of scope). The exceptions are Perl versions 5.005 through 5.00504 and 5.8.0. In these cases, the close method will be called automatically, but not until global destruction of all live objects when the program is terminating. yeah. at the very end. chaotic 😭

So if you want your scripts to be able to run on all versions of Perl, you should call close explicitly and not rely on automatic closing. fr fr, just call it yourself.

Returns true on success, otherwise 0.

If the AutoClose option has been enabled when the IO::Uncompress::Unzip object was created, and the object is associated with a file, the underlying file will also be closed.

nextStream

Usage is:

my $status = $z->nextStream();

Skips to the next compressed data stream in the input file/buffer. If a new compressed data stream is found, the eof marker will be cleared and $. will be reset to 0.

If trailing data is present immediately after the zip archive and the Transparent option is enabled, this method will consider that trailing data to be another member of the zip archive. sneaky little bonus member πŸ‘‘

Returns 1 if a new stream was found, 0 if none was found, and -1 if an error was encountered.

trailingData

Usage is:

my $data = $z->trailingData();

Returns the data, if any, that is present immediately after the compressed data stream once uncompression is complete. It only makes sense to call this method once the end of the compressed data stream has been encountered. like, timing matters here bestie.

This option can be used when there is useful information immediately following the compressed data stream, and you don't know the length of the compressed data stream.

If the input is a buffer, trailingData will return everything from the end of the compressed data stream to the end of the buffer.

If the input is a filehandle, trailingData will return the data that is left in the filehandle input buffer once the end of the compressed data stream has been reached. You can then use the filehandle to read the rest of the input file.

Don't bother using trailingData if the input is a filename. just don't. it's not giving.

If you know the length of the compressed data stream before you start uncompressing, you can avoid having to use trailingData by setting the InputLength option in the constructor. smarter, cleaner, slay πŸ’…


πŸ“¦ Importing

No symbolic constants are required by IO::Uncompress::Unzip at present. none. zero. blessed.

  • :all β€” Imports unzip and $UnzipError. Same as doing this:
use IO::Uncompress::Unzip qw(unzip $UnzipError) ;

🌟 EXAMPLES

Simple Read

Say you have a zip file, file1.zip, that only contains a single member. You can read it and write the uncompressed data to the file file1.txt like this:

use strict ;
use warnings ;
use IO::Uncompress::Unzip qw(unzip $UnzipError) ;

my $filename = "file1.zip";
my $z = IO::Uncompress::Unzip->new($filename)
    or die "IO::Uncompress::Unzip failed: $UnzipError\n";
open my $out, ">", "file1.txt";

while (<$z>) {
    print $out $_;
}
$z->close();

If you have a zip file that contains multiple members and want to read a specific member from the file, say data1, use the Name option when constructing the … (yes, the original sentence just ends there, we love an unfinished thought 😭):

use strict ;
use warnings ;
use IO::Uncompress::Unzip qw(unzip $UnzipError) ;

my $filename = "file1.zip";
my $z = IO::Uncompress::Unzip->new($filename, Name => "data1")
    or die "IO::Uncompress::Unzip failed: $UnzipError\n";

Walking through a zip file

The code below can be used to traverse a zip file, one compressed data stream at a time. this is the good stuff πŸ¦‹

use IO::Uncompress::Unzip qw($UnzipError);

my $zipfile = "somefile.zip";
my $u = IO::Uncompress::Unzip->new( $zipfile )
    or die "Cannot open $zipfile: $UnzipError";

my $status;
for ($status = 1; $status > 0; $status = $u->nextStream())
{

    my $name = $u->getHeaderInfo()->{Name};
    warn "Processing member $name\n" ;

    my $buff;
    while (($status = $u->read($buff)) > 0) {
        # Do something here
    }

    last if $status < 0;
}

die "Error processing $zipfile: $!\n"
    if $status < 0 ;

Each individual compressed data stream is read until the logical end-of-file is reached. Then nextStream is called. This will skip to the start of the next compressed data stream and clear the end-of-file flag.

It is also worth noting that nextStream can be called at any time β€” you don't have to wait until you have exhausted a compressed data stream before skipping to the next one. freedom πŸ’–

Unzipping a complete zip file to disk

Daniel S. Sterling has written a script that uses IO::Uncompress::UnZip to read a zip file and unzip its contents to disk.

The script is available from <https://gist.github.com/eqhmcow/5389877> β€” go check it out, king behaviour πŸ‘‘
