Go package for reading cofig file by JSON, XML, YAML.

go get trellis.tech/trellis/common.v3/config

import gopkg.in/yaml.v3

not supported "*.xml": now go encoding/xml is not supported map[string]any

• dot separator to get values, and if return nil, you should set default value
• A: ${X.Y.Z} for finding out X.Y.Z's value and setting into A. See copy example:See config
• You can do like this: c.GetString("a.b.c") Or c.GetString("a.b.c", "default")
• You can write notes into the json file.
• Supported: .json, .yaml

c, e := NewConfig(name)
c.GetString("a.b.c")

// Config manager data functions
type Config interface {
	// get a object
	GetInterface(key string, defValue ...any) (res any)
	// get a string
	GetString(key string, defValue ...string) (res string)
	// get a bool
	GetBoolean(key string, defValue ...bool) (b bool)
	// get a int
	GetInt(key string, defValue ...int) (res int)
	// get a float
	GetFloat(key string, defValue ...float64) (res float64)
	// get list of objects
	GetList(key string) (res []any)
	// get list of strings
	GetStringList(key string) []string
	// get list of bools
	GetBooleanList(key string) []bool
	// get list of ints
	GetIntList(key string) []int
	// get list of float64s
	GetFloatList(key string) []float64
	// get time duration by (int)(uint), exp: 1s, 1day
	GetTimeDuration(key string, defValue ...time.Duration) time.Duration
	// get byte size by (int)(uint), exp: 1k, 1m
	GetByteSize(key string) *big.Int
	// get map value
	GetMap(key string) Options
	// get key's config
	GetConfig(key string) Config
	// get key's values if values can be Config, or panic
	GetValuesConfig(key string) Config
	// set key's value into config
	SetKeyValue(key string, value any) (err error)
	// get all config
	Dump() (bs []byte, err error)
	// get all keys
	GetKeys() []string
	// deep copy configs
	Copy() Config
}

• JSON
• YAML

// Reader reader repo
type Reader interface {
	// read file into model
	Read(model any) error
	// dump configs' cache
	Dump(model any) ([]byte, error)
	// parse data to model
	ParseData(data []byte, model any) error
}

r := NewReader(ReaderType, filename)
if err := r.Read(model); err != nil {
	return
}

jReader := NewJSONReader() or NewJSONReader(ReaderOptionFilename(filename))
xReader := NewXMLReader()  or NewXMLReader(ReaderOptionFilename(filename))
yReader := NewYAMLReader() or NewYAMLReader(ReaderOptionFilename(filename))

if not set filename with reader option function, you can't use Read function, it will return: no such file or directory

• .json = NewJSONReader()

• .xml = NewXMLReader()

• .yaml | .yml = NewYAMLReader()

• if you want to use a fuzzy reader by filename's suffix

sReader := NewSuffixReader(ReaderOptionFilename(filename))
