Simple-goroutine-local is a cross goroutine storage tool with very simple implementation and function (the concept is similar to Java ThreadLocal).
Getting Started
Installing
To start using GJSON, install Go and run go get:
$ go https://github.com/polarbear567/simple-goroutine-local
This will retrieve the library.
How to use
package main
import (
"fmt"
sgl "github.com/polarbear567/simple-goroutine-local"
"sync"
)
func main() {
gl := sgl.NewGoRoutineLocal()
var wg sync.WaitGroup
wg.Add(5)
gl.Set("value", "main")
for i := 0; i < 5; i++ {
go func(i int) {
defer func() {
wg.Done()
gl.Del(i)
}()
gl.Set("value", i)
v, _ := gl.Get("value")
fmt.Printf("i: %d, v: %d\n", i, v)
}(i)
}
wg.Wait()
v, _ := gl.Get("value")
fmt.Printf("main, value: %s\n", v)
gl.Del("value")
v, ok := gl.Get("value")
fmt.Printf("main, value after delete: %v, value exist: %t\n", v, ok)
gl.DelMap()
if v, ok = gl.Get("value"); !ok {
fmt.Printf("main, map exist: %t\n", ok)
}
}
The output:
i: 4, v: 4
i: 2, v: 2
i: 1, v: 1
i: 0, v: 0
i: 3, v: 3
main, value: main
main, value after delete: <nil>, value exist: false
main, map exist: false
Tip
Since goroutine may be reused, please make sure to explicitly set in the current goroutine before get, or delete the key before the end of the current goroutine.
