IO::All Description

IO::All combines all of the best Perl IO modules into a single nifty object oriented interface. IO::All - IO::All of it to Graham and Damian!SYNOPSIS use IO::All; # Let the madness begin... # Some of the many ways to read a whole file into a scalar io('file.txt') > $contents; # Overloaded "arrow" $contents < io 'file.txt'; # Flipped but same operation $io = io 'file.txt'; # Create a new IO::All object $contents = $$io; # Overloaded scalar dereference $contents = $io->all; # A method to read everything $contents = $io->slurp; # Another method for that $contents = join '', $io->getlines; # Join the separate lines $contents = join '', map "$_n", @$io; # Same.

It exports a single function called io, which returns a new IO::All object. And that object can do it all!The IO::All object is a proxy for IO::File, IO::Dir, IO::Socket, IO::String, Tie::File, File::Spec, File::Path and File::ReadBackwards; as well as all the DBM and MLDBM modules. You can use most of the methods found in these classes and in IO::Handle (which they inherit from). IO::All adds dozens of other helpful idiomatic methods including file stat and manipulation functions.IO::All is pluggable, and modules like IO::All::LWP and IO::All::Mailto add even more functionality. Optionally, every IO::All object can be tied to itself. This means that you can use most perl IO builtins on it: readline, , getc, print, printf, syswrite, sysread, close.The distinguishing magic of IO::All is that it will automatically open (and close) files, directories, sockets and other IO things for you. You never need to specify the mode ('>', etc), since it is determined by the usage context. That means you can replace this: open STUFF, ' Requirements: · Perl
