exporter::lite
Exporter::Lite(3pm) User Contributed Perl Documentation Exporter::Lite(3pm)
NAME
Exporter::Lite - Lightweight exporting of variables
SYNOPSIS
package Foo;
use Exporter::Lite;
# Just like Exporter.
@EXPORT = qw($This That);
@EXPORT_OK = qw(@Left %Right);
# Meanwhile, in another piece of code!
package Bar;
use Foo; # exports $This and &That.
DESCRIPTION
This is an alternative to Exporter intended to provide a lightweight subset of its functionality. It supports "import()", @EXPORT and
@EXPORT_OK and not a whole lot else.
Unlike Exporter, it is not necessary to inherit from Exporter::Lite (ie. no "@ISA = qw(Exporter::Lite)" mantra). Exporter::Lite simply
exports its import() function. This might be called a "mix-in".
Setting up a module to export its variables and functions is simple:
package My::Module;
use Exporter::Lite;
@EXPORT = qw($Foo bar);
now when you "use My::Module", $Foo and "bar()" will show up.
In order to make exporting optional, use @EXPORT_OK.
package My::Module;
use Exporter::Lite;
@EXPORT_OK = qw($Foo bar);
when My::Module is used, $Foo and "bar()" will not show up. You have to ask for them. "use My::Module qw($Foo bar)".
Methods
Export::Lite has one public method, import(), which is called automaticly when your modules is use()'d.
In normal usage you don't have to worry about this at all.
import
Some::Module->import;
Some::Module->import(@symbols);
Works just like "Exporter::import()" excepting it only honors @Some::Module::EXPORT and @Some::Module::EXPORT_OK.
The given @symbols are exported to the current package provided they are in @Some::Module::EXPORT or @Some::Module::EXPORT_OK.
Otherwise an exception is thrown (ie. the program dies).
If @symbols is not given, everything in @Some::Module::EXPORT is exported.
DIAGNOSTICS
'"%s" is not exported by the %s module'
Attempted to import a symbol which is not in @EXPORT or @EXPORT_OK.
'Can't export symbol: %s'
Attempted to import a symbol of an unknown type (ie. the leading $@% salad wasn't recognized).
BUGS and CAVEATS
Its not yet clear if this is actually any lighter or faster than Exporter. I know its at least on par.
OTOH, the docs are much clearer and not having to say "@ISA = qw(Exporter)" is kinda nice.
