NAME IO::Any - open anything SYNOPSIS # NOTE commented out lines doesn't work (yet) use IO::Any; $fh = IO::Any->read('filename'); $fh = IO::Any->read('file://var/log/syslog'); #$fh = IO::Any->read('http://search.cpan.org/'); #$fh = IO::Any->read('-'); $fh = IO::Any->read(['folder', 'other-folder', 'filename']); $fh = IO::Any->read('folder'); $fh = IO::Any->read("some text\nwith more lines\n"); $fh = IO::Any->read(\"some text\nwith more lines\n"); $fh = IO::Any->read('{"123":[1,2,3]}'); $fh = IO::Any->read('abc'); $fh = IO::Any->read(*DATA); $fh = IO::Any->read(IO::String->new("cba")); #$fh = IO::Any->read($object_with_toString_method); $fh = IO::Any->write('filename'); $fh = IO::Any->write('file://var/log/syslog'); #$fh = IO::Any->write('-'); $fh = IO::Any->write(['folder', 'filename']); #$fh = IO::Any->write('='); my $string; $fh = IO::Any->write(\$string); my $content = IO::Any->slurp(['folder', 'filename']); IO::Any->spew(['folder2', 'filename'], $content); perl -MIO::Any -le 'print IO::Any->slurp("/etc/passwd")' perl -MIO::Any -le 'IO::Any->spew("/tmp/timetick", time())' DESCRIPTION The aim is to provide read/write anything. The module tries to guess `$what' the "anything" is based on some rules. See new method Pod for examples and the new and _guess_what entries elsewhere in this document code for the implementation. There are two methods the slurp and spew entries elsewhere in this document to read/write whole `$what'. MOTIVATION The purpose is to be able to use IO::Any in other modules that needs to read or write data. The description for an argument could be - pass anything that IO::Any accepts as argument - GLOBs, IO::File, Path::Class::File, IO::AtomicFile, IO::String, pointers to scalar and pointer to array (array elements are passed to File::Spec as portable file addressing). First time I've used IO::Any for JSON::Util where for the functions to encode and decode needs to read/write data. METHODS new($what, $how, $options) Open `$what' in `$how' mode. `$what' can be: 'filename' => [ 'file' => 'filename' ], 'folder/filename' => [ 'file' => 'folder/filename' ], 'file:///folder/filename' => [ 'file' => '/folder/filename' ], [ 'folder', 'filename' ] => [ 'file' => File::Spec->catfile('folder', 'filename') ], 'http://a/b/c' => [ 'http' => 'http://a/b/c' ], 'https://a/b/c' => [ 'http' => 'https://a/b/c' ], '{"123":[1,2,3]}' => [ 'string' => '{"123":[1,2,3]}' ], '[1,2,3]' => [ 'string' => '[1,2,3]' ], '' => [ 'string' => '' ], "a\nb\nc\n" => [ 'string' => "a\nb\nc\n" ], *DATA => [ 'file' => *{DATA}{IO} ], Returns filehandle. IO::String for 'string', IO::File for 'file'. 'http' not implemented yet. Here are available `%$options' options: atomic true/false if the file operations should be done using L or L LOCK_SH lock file for shared access LOCK_EX lock file for exclusive LOCK_NB lock file non blocking (will throw an excpetion if file is already locked, instead of blocking the process) _guess_what Returns ($type, $what). $type can be: file string http iostring iofile `$what' is normalized path that can be used for IO::*. read($what) Same as `IO::Any->new($what, '<');' or `IO::Any->new($what);'. write($what) Same as `IO::Any->new($what, '>');' slurp($what) Returns content of `$what'. If AnyEvent is loaded then uses event loop to read the content. spew($what, $data, $opt) Writes `$data' to `$what'. If AnyEvent is loaded then uses event loop to write the content.
