# envload
Restore environment variables, so you can break 'em
[](https://travis-ci.org/lestrrat-go/envload)

# SYNOPSIS
# DESCRIPTION
Certain applications that require reloading of configuraiton from
environment variables are sensitive to these values being changed.
Or maybe you are writing a test that wants to temporarily change the
value of an environment variable, but you don't want it to linger afterwards.
In other languages this can be done with a "temporary" variable, like in
Perl5:
```perl
use strict;
use 5.24;
sub foo {
$ENV{IMPORTANT_VAR} = "foo";
say $ENV{IMPORTANT_VAR}; # "foo"
{
local %ENV = %ENV; # inherit the original %ENV,
$ENV{IMPORTANT_VAR} = "bar";
say $ENV{IMPORTANT_VAR}; # "bar"
}
#
say $ENV{IMPORTANT_VAR}; # "bar"
}
```
This library basically allows you to do this in Go
