go.incremental
Go package incremental provides typed incremental counters that are type-safe.
Install
go get github.com/GeertJohan/go.incremental
Usage example
This example is also located in the example subdirectory
package main
import (
"fmt"
"github.com/GeertJohan/go.incremental"
"runtime"
)
func main() {
// use max cpu's
runtime.GOMAXPROCS(runtime.NumCPU())
// create new incremental.Int
i := &incremental.Int{}
// print some numbers
fmt.Println(i.Next()) // print 1
fmt.Println(i.Next()) // print 2
fmt.Println(i.Next()) // print 3
// create chan to check if goroutines are done
done := make(chan int)
// spawn 4 goroutines
for a := 0; a < 4; a++ {
// call goroutine with it's number (0-3)
go func(aa int) {
// print 10 incremental numbers
for b := 0; b < 10; b++ {
fmt.Printf("routine %d: %d\n", aa, i.Next())
}
// signal done
done <- aa
}(a)
}
// wait until all goroutines are done
for a := 0; a < 4; a++ {
fmt.Printf("goroutine %d done\n", <-done)
}
fmt.Println("all done")
}
