NAME

Env::Sanctify - Lexically scoped sanctification of %ENV

SYNOPSIS

   my $sanctify = Env::Sanctify->sanctify( sanctify => [ '^POE' ] );
 
   # do some stuff, fork some processes etc.
 
   $sanctify->restore
 
   { 
 
     my $sanctify = Env::Sanctify->sanctify( env => { POE_TRACE_DEFAULT => 1 } );
 
     # do some stuff, fork some processes etc.
   }
 
   # out of scope, %ENV is back to normal
 
 

DESCRIPTION

Env::Sanctify is a module that provides lexically scoped manipulation and sanctification of %ENV.

You can specify that it alter or add additional environment variables or remove existing ones according to a list of matching regexen.

You can then either "restore" the environment back manually or let the object fall out of scope, which automagically restores.

Useful for manipulating the environment that forked processes and sub-processes will inherit.

CONSTRUCTOR

"sanctify"

Creates an Env::Sanctify object. Takes two optional arguments:

   'env', a hashref of env vars to add to %ENV;
   'sanctify', an arrayref of regex pattern strings to match against current %ENV vars;
 
 

Any %ENV var that matches a "sanctify" regex is removed from the resultant %ENV.

METHODs

"restore"

Explicitly restore the previous %ENV. This is called automagically when the object is "DESTROY"ed, for instance, when it goes out of scope.
