Scalar::Readonly - functions for controlling whether any scalar variable is read-only River stage one • 3 direct dependents • 3 total dependents

This simple module can make scalars read-only. Useful to protect configuration variables, for example. This module can also be used to subvert Perl's many read-only variables to potential evil trickery. readonly Ths function takes a scalar variable a...

Fixed - a readonly variable that you can assign to River stage zero No dependents

"Fixed" is a little like Readonly; the main difference is that you can assign to fixed variables. What?! Then how are they fixed? Because you can only assign to them once! use 5.012; use strict; use warnings; use Fixed; fix $x; # declared but not ini...

ex::constant::vars - create readonly variables (alternative to constant pragma) River stage zero No dependents

This package allows you to create readonly variables. Unlike the "constant" pragma, this module lets you create readonly scalars, arrays and hashes. This module "tie()"s variables to a class that disables any attempt to modify a variable's data. Scal...

Scalar::Util - A selection of general-utility scalar subroutines River stage five • 2507 direct dependents • 21315 total dependents

"Scalar::Util" contains a selection of subroutines that people have expressed would be nice to have in the perl core, but the usage would not really be high enough to warrant the use of a keyword, and the size would be so small that being individual ...

Convert::Scalar - convert between different representations of perl scalars River stage one • 3 direct dependents • 7 total dependents

This module exports various internal perl methods that change the internal representation or state of a perl scalar. All of these work in-place, that is, they modify their scalar argument. No functions are exported by default. The following export ta...

Tie::Persistent - persistent data structures via tie made easy River stage zero No dependents

The Tie::Persistent package makes working with persistent data real easy by using the "tie" interface. It works by storing data contained in a variable into a file (not unlike a database). The primary advantage is speed, as the whole datastructure is...

Tie::Scalar::Epoch - Create a scalar that always returns the number of non-leap seconds since whatever time the system considers to be the epoch. River stage zero No dependents

This is a very simple class that creates readonly scalars that always return the current epoch. A variables tied to this class is readonly, and attempting to assign to it will raise an exception....

Tie::Scalar::Timestamp - Create a scalar that always returns the current timestamp River stage zero No dependents

This is a very simple class that creates readonly scalars that always return the current timestamp. By default, it uses the format "yyyy-mm-ddThh:mm:ss" (or, in strftime notation, "%Y-%m-%dT%H:%M:%S") and local time. You can optionally pass a hashref...
