Description

This module contains the basic types used by the library and their typeclass instances.

Synopsis

data RichEnv = RichEnv {
- values :: Values
- mappings :: Mappings
- prefixes :: Prefixes
}
defaultRichEnv :: RichEnv
type Environment = [(Text, Text)]
newtype Mappings = Mappings {
- unMappings :: HashMap Text Text
}
newtype Values = Values {
- unValues :: HashMap Text Text
}
newtype Prefixes = Prefixes {
- unPrefixes :: HashMap Text [Text]
}
toEnvironment :: [(String, String)] -> Environment
fromEnvironment :: Environment -> [(String, String)]

Types

data RichEnv Source #

Type that represents a set of rules that generate environment variables. A value of this type can be retrieved from a configuration file (e.g. YAML) due to its FromJSON instance, or persisted into one with ToJSON.

Constructors

RichEnv
Fields values :: Values A list of environment variables to be set with their values. mappings :: Mappings Mappings from one existing environment variable name to another. prefixes :: Prefixes Mappings from different prefixes of existing environment variables to new prefixes.

defaultRichEnv :: RichEnv Source #

Default RichEnv value. With everything empty.

type Environment = [(Text, Text)] Source #

A list of key-value pairs representing environment variables.

newtype Mappings Source #

A list of key-value pairs representing environment variable name mappings. The internal representation is a 'HashMap Text Text', where the key is the final variable name and the value is the current one which will be replaced.

Environment transformations

toEnvironment :: [(String, String)] -> Environment Source #

Transform the type returned from getEnvironment ([(String, String)]) to use Text instead.

fromEnvironment :: Environment -> [(String, String)] Source #

Get back a [(String, String)] from an Environment.
