getConfigValue, getConfigValueWith, getAllConfigSources, getSelectedConfigSource

Methods

getConfigValue

Arguments

:: (MonadThrow m, FromJSON result)

=> [Text]

Key to fetch from config map

-> config

Config record

-> m result

Fetches a configuration value from a given key, if key is not found, you may pick the failure mode via the MonadThrow interface.

example:

>>> getConfigValue ["db", "user"] config :: Maybe Text
Just "root"
>>> getConfigValue ["db", "password"] config :: Maybe Text
Nothing

getConfigValueWith

Arguments

:: MonadThrow m

=> (Value -> Parser result)

JSON Parser function

-> [Text]

Key to fetch from config map

-> config

Config record

-> m result

Fetches a configuration value from a given key, normally this key will point to a sub-config JSON object, which is then passed to the given JSON parser function. If key is not found, you may pick the failure mode via the MonadThrow interface.

example:

>>> import qualified Data.Aeson as JSON
>>> import qualified Data.Aeson.Types as JSON (Parser)

>>> connectInfoParser :: JSON.Value -> JSON.Parser DbConnectInfo

>>> getConfigValueWith connectInfoParser ["db"] config
Just (DbConnectInfo {...})

getAllConfigSources :: MonadThrow m => [Text] -> config -> m (Set ConfigSource)

getSelectedConfigSource :: MonadThrow m => [Text] -> config -> m ConfigSource
