Functions

func Get

func Get(name string) string

Get retrieves and returns the stored tag content for specified name.

func Parse

func Parse(content string) string

Parse parses and returns the content by replacing all tag name variable to its content for given `content`. Eg: gtag.Set("demo", "content") Parse(`This is {demo}`) -> `This is content`.

func Set

func Set(name, value string)

Set sets tag content for specified name. Note that it panics if `name` already exists.

Example

package main

import (
	"fmt"

	"github.com/gogf/gf/v2/frame/g"
	"github.com/gogf/gf/v2/util/gmeta"
	"github.com/gogf/gf/v2/util/gtag"
)

func main() {
	type User struct {
		g.Meta `name:"User Struct" description:"{UserDescription}"`
	}
	gtag.Sets(g.MapStrStr{
		`UserDescription`: `This is a demo struct named "User Struct"`,
	})
	fmt.Println(gmeta.Get(User{}, `description`))

}

Output:

This is a demo struct named "User Struct"

func SetOver

func SetOver(name, value string)

SetOver performs as Set, but it overwrites the old value if `name` already exists.

func Sets

func Sets(m map[string]string)

Sets sets multiple tag content by map.

func SetsOver

func SetsOver(m map[string]string)

SetsOver performs as Sets, but it overwrites the old value if `name` already exists.
