Tie::Handle(3perl)

💖 Tie::Handle — bestie edition 💖

okay so real talk: this is the manual page for Tie::Handle(3perl) from the Perl Programmers Reference Guide. yes the same docs that ship in your perl. let's get into it 🦋

✨ NAME ✨

Tie::Handle — the base class definitions for tied handles, periodt 👑

🌸 SYNOPSIS 🌸

here's the vibe, copy it exactly bestie:

package NewHandle;
require Tie::Handle;

@ISA = qw(Tie::Handle);

sub READ { ... }            # Provide a needed method
sub TIEHANDLE { ... }       # Overrides inherited method

package main;

tie *FH, 'NewHandle';

💅 DESCRIPTION 💅

so basically this module hands you some skeletal methods for classes that wanna do handle-tying. if you need the full rundown of which functions are required when you tie a handle to a package, go peek at perltie — it's the syllabus, fr fr.

the basic Tie::Handle package gives you a "new" method, plus the methods "TIEHANDLE", "PRINT", "PRINTF" and "GETC". that's the starter pack 🎀

now, for the devs out there who are writing their own tied-handle classes, here's the method summary. the perltie section doesn't just document these — it's got sample code too, so go look, iykyk:

TIEHANDLE classname, LIST : The method invoked by the command tie *glob, classname. It associates a new glob instance with the specified class. LIST would represent additional arguments (along the lines of AnyDBM_File and compatriots) needed to complete the association.

WRITE this, scalar, length, offset : Write length bytes of data from scalar starting at offset.

PRINT this, LIST : Print the values in LIST

PRINTF this, format, LIST : Print the values in LIST using format

READ this, scalar, length, offset : Read length bytes of data into scalar starting at offset.

READLINE this : Read a single line

GETC this : Get a single character

CLOSE this : Close the handle

OPEN this, filename : (Re-)open the handle

BINMODE this : Specify content is binary

EOF this : Test for end of file.

TELL this : Return position in the file.

SEEK this, offset, whence : Position the file.

: Test for end of file.

DESTROY this : Free the storage associated with the tied handle referenced by this. This is rarely needed, as Perl manages its memory quite well. But the option exists, should a class wish to perform specific actions upon the destruction of an instance.

ok and yes, that "Test for end of file." line really does show up twice in the original page — i'm keeping it real with you and keeping it exactly where it was 💀

🔥 MORE INFORMATION 🔥

The perltie section contains an example of tying handles. go. read. it. it's giving tutorial energy ✨

👑 COMPATIBILITY 👑

This version of Tie::Handle is neither related to nor compatible with the Tie::Handle (3.0) module available on CPAN. it was due to an accident that two modules with the same name appeared 😭 (iconic mess, honestly).

The namespace clash has been cleared in favor of this module that comes with the perl core in September 2000 and accordingly the version number has been bumped up to 4.0. slay, conflict resolved 🫶

and that's the whole page bestie, no notes 💜 this was Tie::Handle(3perl) from perl v5.44.0, dated 2026-10-17 — talk soon, mwah 🎀✨
