Package podopts is a configuration system to fit with the all-in-one philosophy guiding the design of the parallelcoin pod.

The configuration is stored by each component of the connected applications, so all data is stored in concurrent-safe atomics, and there is a facility to invoke a function in response to a new value written into a field by other threads.

There is a custom JSON marshal/unmarshal for each field type and for the whole configuration that only saves values that differ from the defaults, similar to 'omitempty' in struct tags but where 'empty' is the default value instead of the default zero created by Go's memory allocator. This enables easy compositing of multiple sources.

Config defines the configuration items used by pod along with the various components included in the suite

func (*Config) ForEach

func (c *Config) ForEach(fn func(ifc opt.Option) bool) bool

ForEach iterates the options in defined order with a closure that takes an opt.Option

func (*Config) GetOption

func (c *Config) GetOption(input string) (op opt.Option, value string, e error)

GetOption searches for a match amongst the podopts

func (*Config) Initialize

func (c *Config) Initialize() (e error)

Initialize loads in configuration from disk and from environment on top of the default base

func (*Config) MarshalJSON

func (c *Config) MarshalJSON() (b []byte, e error)

MarshalJSON implements the json marshaller for the config. It only stores non-default values so can be composited.

func (*Config) ReadCAFile

func (c *Config) ReadCAFile() []byte

ReadCAFile reads in the configured Certificate Authority for TLS connections

func (*Config) UnmarshalJSON

func (c *Config) UnmarshalJSON(data []byte) (e error)

UnmarshalJSON implements the Unmarshaller interface so it only writes to fields with those non-default values set.

func (*Config) WriteToFile

func (c *Config) WriteToFile(filename string) (e error)

WriteToFile writes the current config to a file as json

type ConfigSlice

type ConfigSlice []ConfigSliceElement

func (ConfigSlice) Len

func (c ConfigSlice) Len() int

func (ConfigSlice) Less

func (c ConfigSlice) Less(i, j int) bool

func (ConfigSlice) Swap

func (c ConfigSlice) Swap(i, j int)

type ConfigSliceElement

type ConfigSliceElement struct {
	Opt  opt.Option
	Name string

type Configs

type Configs map[string]opt.Option

Configs is the source location for the Config items, which is used to generate the Config struct
