Functions

func Get

func Get(tag, key string) string

Example

fmt.Println(Get(`a:"av"`, `a`))

Output:

av

func Lookup

func Lookup(tag, key string) (value string, ok bool)

Example (False)

fmt.Println(Lookup(``, ``))
fmt.Println(Lookup(` `, ``))
fmt.Println(Lookup(`a`, ``))
fmt.Println(Lookup(`a:""`, ``))
fmt.Println(Lookup(`a:"av"`, `b`))

Output:

 false
 false
 false
 false
 false

Example (True)

fmt.Println(Lookup(`a:""`, `a`))
fmt.Println(Lookup(`a:"av"`, `a`))
fmt.Println(Lookup(`a:"av" b:"b\" v"`, `b`))
fmt.Println(Lookup(`a:"av"
		b:"b v" `, `b`))
fmt.Println(Lookup(`名称:"值
\"def"`, `名称`))

Output:

 true
av true
b" v true
b v true
值
"def true

func Parse

func Parse(tag string) (result map[string]string)

Example (True)

fmt.Println(Parse(`a:""`))
fmt.Println(Parse(`a:"av"`))
fmt.Println(Parse(`a:"av" b:"b\" v"`))
fmt.Println(Parse(`a:"av"
		b:"b v" `))
fmt.Println(Parse(`名称:"值
\"def"`))

Output:

map[a:]

map[a:av b:b" v]
map[a:av b:b v]
map[名称:值
"def]
