.SH "NAME"
UNIVERSAL::exports \- Lightweight, universal exporting of variables
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
.Vb 2
\&  package Foo;
\&  use UNIVERSAL::exports;
\&
\&  # Just like Exporter.
\&  @EXPORT       = qw($This &That);
\&  @EXPORT_OK    = qw(@Left %Right);
\&
\&
\&  # Meanwhile, in another piece of code!
\&  package Bar;
\&  use Foo;  # exports $This and &That.
.Ve
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This is an alternative to Exporter intended to provide a universal,
lightweight subset of its functionality.  It uses Exporter::Lite, so
look there for details.
.PP
Additionally, \f(CW\*(C`exports()\*(C'\fR is provided to find out what symbols a
module exports.
.PP
UNIVERSAL::exports places its methods in the \s-1UNIVERSAL\s0 namespace, so
there is no need to subclass from it.
.SH "Methods"
.IX Header "Methods"
UNIVERSAL::exports has two public methods, \fIimport()\fR derived from
Exporter::Lite, and \fIexports()\fR.
.IP "\fBimport\fR" 4
.IX Item "import"
.Vb 2
\&  Some::Module\->import;
\&  Some::Module\->import(@symbols);
.Ve
.Sp
This is Exporter::Lite's \fIimport()\fR method.  Look in Exporter::Lite
for details.
.IP "\fBexports\fR" 4
.IX Item "exports"
.Vb 2
\&  @exported_symbols = Some::Module\->exports;
\&  Some::Module\->exports($symbol);
.Ve
.Sp
Reports what symbols are exported by Some::Module.  With no arguments,
it simply returns a list of all exportable symbols.  Otherwise, it
reports if it will export a given \f(CW$symbol\fR.
.SH "DIAGNOSTICS"
.IX Header "DIAGNOSTICS"
.ie n .IP "'""%s"" is not exported by the %s module'" 4
.el .IP "'``%s'' is not exported by the \f(CW%s\fR module'" 4
.IX Item "'%s is not exported by the %s module'"
Attempted to import a symbol which is not in \f(CW@EXPORT\fR or \f(CW@EXPORT_OK\fR.
.ie n .IP "'Can\e't export symbol: %s'" 4
.el .IP "'Can\e't export symbol: \f(CW%s\fR'" 4
.IX Item "'Can't export symbol: %s'"
Attempted to import a symbol of an unknown type (ie. the leading $@% salad
wasn't recognized).
