Version: 0.22
This module allows the user to specify one or more environment variables that
should be “exported” to the calling namespace as constant subroutines. By
doing this, their existence/inexistence can be detected at compile-time.
The difference is in how you detect the absence of the environment variable
you need:
if (exists($ENV{PATH}) and ($ENV{PATH} =~ /.../))
{
# Do something
}
versus:
use Env::Export 'PATH';
if (PATH =~ /.../)
{
# Do something
}
The first form performs two tests, the first to ensure that the second does
not cause a “Use of unitialized value in regular expression” warning. The
second form only performs one test, but it also generates a compile-time
error if there was no environment variable “PATH” present.
This package provides a Makefile.PL file as is typical of CPAN modules.
Building and installing is as easy as:
perl Makefile.PL
make
make test
# If tests pass
make install
(The “make install” step may require super-user privileges.)
