Config represents Choria configuration

NOTE: When adding or updating doc strings please run `go generate` in the root of the repository

func NewConfig 

func NewConfig(path string) (*Config, error)

NewConfig parses a config file and return the config

func NewConfigForTests 

func NewConfigForTests() *Config

NewConfigForTests creates a configuration for use in testing tools

func NewDefaultConfig 

func NewDefaultConfig() (*Config, error)

NewDefaultConfig creates a empty configuration

func NewDefaultSystemConfig added in v0.20.0 

func NewDefaultSystemConfig(server bool) (*Config, error)

NewDefaultSystemConfig creates a new configuration for system services

func NewSystemConfig added in v0.20.0 

func NewSystemConfig(path string, server bool) (*Config, error)

func (*Config) ApplyBuildSettings 

func (c *Config) ApplyBuildSettings(b BuildInfoProvider)

ApplyBuildSettings applies build time overrides to the configuration

func (*Config) ConfigKeys 

func (c *Config) ConfigKeys(re string) (found []string, err error)

ConfigKeys retrieves all known configuration keys matching re

func (*Config) DocForConfigKey 

func (c *Config) DocForConfigKey(k string) *confkey.Doc

func (*Config) HasOption 

func (c *Config) HasOption(option string) bool

HasOption determines if a specific option was set from a config key. The option given would be something like `plugin.choria.use_srv` and true would indicate that it was set by config vs using defaults

func (*Config) Option 

func (c *Config) Option(option string, deflt string) string

Option retrieves the raw string representation of a given option from that was loaded from the configuration

func (*Config) SetOption 

func (c *Config) SetOption(option string, value string)

SetOption sets a raw string option, can be used to programatically set plugin options etc, setting a main config item value here does not update the values in the strings, so this is only really useful for setting plugin options

func (*Config) UnParsedOptions added in v0.20.0 

func (c *Config) UnParsedOptions() map[string]string

UnParsedOptions are the options loaded

type Mutator 

type Mutator interface {
	Mutate(*Config, *logrus.Entry)
}

Mutator is a function that can mutate the configuration
