NAME Sub::Lvalue - use lvalue subroutines with ease VERSION Version 0.01 SYNOPSIS Simply put get and set blocks at the end of your lvalue sub. Please note, no comma or semicolon between statements are allowed (in case of semicolon only last statement will be take an action) use Sub::Lvalue; sub mysub : lvalue { get { return 'result for get'; } set { my $set_value = shift; # ... } } mysub() = 'test'; # will invoke set block with argument 'test'; print mysub(); # will invoke get block without arguments. result will be returned to print; sub readonly : lvalue { get { return 'readonly value'; } } print readonly(); # ok readonly = 'test'; # fails sub writeonly : lvalue { set { my $set_value = shift; # ... } } writeonly = 'test'; # ok print writeonly(); # fails EXPORT There are 2 export functions: "set" and "get". If you don't want to use export, you may use full names sub mysub : lvalue { Sub::Lvalue::get { return 'something'; } Sub::Lvalue::set { my $set_value = shift; } } FUNCTIONS set invoked with argument from right side get invoked without arguments. the returned value passed out RENAMING From it's creation in 2009 till 2016 this module has name lvalue. In 2010 there were appeared module Lvalue. During years, there were semantic conflict between Lvalue and lvalue. But this days PAUSE threats CPAN module names case insensitive that leads us to name conflict. After all, there is another great module LV. As stated by its author, some part of it was inspired by "lvalue". I decided to eliminame original name lvalue and to keep original source code if someone needs it under the name Sub::Lvalue AUTHOR Mons Anderson, BUGS None known COPYRIGHT & LICENSE Copyright 2009 Mons Anderson.
