I saw a question people asked which is how to make a commandline process bar by Golang.
Here is a simple one I did.
package main
import (
"fmt"
"strconv"
"time"
)
func main() {
for i := 10; i <= 100; i += 10 {
str := "[" + bar(i/5, 20) + "] " + strconv.Itoa(i) + "%"
fmt.Printf("\r%s", str)
time.Sleep(1 * time.Second)
}
fmt.Println()
}
func bar(count, size int) string {
str := ""
for i := 0; i < size; i++ {
if i < count {
str += "="
} else {
str += " "
}
}
return str
}The result will look like this:
