DESCRIPTION
This module load multiple config files using Config::Any. You can specify directory and put into your config files!
I create this module because I want to load not only loading multiple config files but also switch config files depend on interface I am using. like, I want to load web.yml only for web interface configuration and cli.yml for only for client interface configuration. let me explain step by step at EXAMPLE section.
EXAMPLE
your configuration files
This is under your ~/myapp/conf/ and have yaml configuration in each files. you can specify the directory using dir option.
.
|-- env-prefix.yml
|-- env.yml
|-- myapp.yml
|-- myapp_boin.yml
|-- myapp_local.yml
|-- myapp_oppai.yml
|-- never_load.yml
|-- web_myapp.yml
|-- web_myapp_cat.yml
|-- web_myapp_dog.yml
`-- web_myapp_local.yml
switchable
when you set app_name as 'myapp' and prefix as 'jobqueue' then below files are loaded
|-- myapp.yml
|-- myapp_boin.yml
|-- myapp_local.yml
|-- myapp_oppai.yml
${app_name}.yml or ${app_name}_*.yml
when you set app_name as 'myapp' and prefix as 'web' then below files are loaded
|-- myapp.yml
|-- myapp_boin.yml
|-- myapp_local.yml
|-- myapp_oppai.yml
|-- web_myapp.yml
|-- web_myapp_cat.yml
|-- web_myapp_dog.yml
`-- web_myapp_local.yml
${prefix}_${myapp}.yml ${prefix}_${myapp}_*.yml
YES! you can switch config files depend on what you set for app_name and prefix.
overwrite rule.
there is also overwriting rule. there are three steps for this.
_local.yml file overwrite the other config setting
${prefix}_${app_name}_local.yml
${app_name}_local.yml
${prefix}_ files overwrite ${app_name} config setting
${app_name}.yml, ${app_name}_*.yml (not include ${app_name}_local.yml)
app config.
${prefix}_${myapp}.yml ${prefix}_${myapp}_*.yml
$ENV setting
instead of ${prefix}_${app_name}_local.yml , you can specify the path with $ENV{CONFIG_MULTI_PREFIX_MYAPP}
instead of ${app_name}_local.yml , you can specify the path with $ENV{CONFIG_MULTI_MYAPP}
note. PREFIX = uc($prefix); MYAPP = uc($app_name)
