Yesod.Default.Config2

Location of the default config file.

Helper for getApplicationDev in the scaffolding. Looks up PORT and DISPLAY_PORT and prints appropriate messages.

Helper for develMain in the scaffolding.

Create a Logger value (from yesod-core) out of a LoggerSet (from fast-logger).

A convenience wrapper around applyEnvValue and getCurrentEnv

Get the actual environment as a HashMap from Text to Text.

Override environment variable placeholders in the given Value with values from the environment.

If the first argument is True, then all placeholders _must_ be provided by the actual environment. Otherwise, default values from the Value will be used.

Load the settings from the following three sources:

• Run time config files

• Run time environment variables

• The default compile time config file

For example, to load up settings from config/foo.yaml and allow overriding from the actual environment, you can use:

loadYamlSettings ["config/foo.yaml"] [] useEnv

Same as loadYamlSettings, but get the list of runtime config files from the command line arguments.

Defines how we want to use the environment variables when loading a config file. Use the smart constructors provided by this module.

Do not use any environment variables, instead relying on defaults values in the config file.

Use environment variables when available, otherwise use defaults.

Do not use default values from the config file, but instead take all overrides from the environment. If a value is missing, loading the file will throw an exception.

Same as useEnv, but instead of the actual environment, use the provided HashMap as the environment.

Same as requireEnv, but instead of the actual environment, use the provided HashMap as the environment.

Load the settings from the following three sources:

• Run time config files

• Run time environment variables

• The default compile time config file

Same as loadAppSettings, but get the list of runtime config files from the command line arguments.
