perl-dotenv's Introduction

Perl Simple DotEnv

load enviroment vaiabled with Perl from a file in .env (dotenv) format.

Server Install

Install the module you Perl module path.

load module and call sub source_dotenv();

use DotenvSimple;
DotenvSimple::source_dotenv('/tmp/.env');

Here's a sample /tmp/.env, can follow any of the below formats

# <--- hashes or comments are ignored
# we also ignore export, white spaces and semicolons
export  DD_DATABASE_NAME = issm_lists_stage;
# single and double quotes for values are allowed
DD_DATABASE_USER=dev
DD_DATABASE_PASSWD=dev
DD_DATABASE_HOST='192.168.33.1'
DD_DATABASE_PORT='3306';
DD_DATABASE_Type = "mysql";

Refferancing key a key to get teh value from the above .env files:

print $ENV{DD_DATABASE_HOST}; output > 192.168.33.1

Options

Loading dotenv in this order. Once found it will stop searching for dotenv.

You pass the path of you dotenv file as a parameter DotenvSimple::source_dotenv('/tmp/.env');
If you set a Perl accessable enviroment parameter $ENV{DOTENV_FILE} the subroutine will use the value of this vaiable. Use case would be to define this in apache vhost configs like so

<VirtualHost hostname:80>
   ...
   SetEnv DOTENV_FILE /tmp/.env
   ...
</VirtualHost>

Generally when using Apache, the document root variable $ENV{DOCUMENT_ROOT}, is loaded into perl. if using HTTPD it will also search for .env in your document root.
