SYNOPSIS

package MyConfig;

use Config::ENV 'PLACK_ENV'; # use $ENV{PLACK_ENV} to determine config

common +{
  name => 'foobar',
};

config development => +{
  dsn_user => 'dbi:mysql:dbname=user;host=localhost',
};

config test => +{
  dsn_user => 'dbi:mysql:dbname=user;host=localhost',
};

config production => +{
  dsn_user => 'dbi:mysql:dbname=user;host=127.0.0.254',

DESCRIPTION

Config::ENV is for switching various configurations by environment variable.

CONFIG DEFINITION

use this module in your config package:

package MyConfig;
use Config::ENV 'FOO_ENV';

common +{
  name => 'foobar',
};

config development => +{};
config production  => +{};

1;

common($hash)

Define common config. This $hash is merged with specific environment config.

config($env, $hash);

Define environment config. This $hash is just enabled in $env environment.

parent($env);

Expand $env configuration to inherit it.

load($filename);

`do $filename` and expand it. This can be used following:

# MyConfig.pm
common +{
  API_KEY => 'Set in config.pl',
  API_SECRET => 'Set in config.pl',
  load('config.pl),
};

# config.pl
+{
  API_KEY => 'XFATEAFAFASG',
  API_SECRET => 'ced3a7927fcf22cba72c2559326be2b8e3f14a0f',
