While on my path to learning Scala, or rather improving my very lacking Scala knowledge I've written a progress bar for the command line...
I'm pretty sure it is far more verbose than it needs to be, but until I know how to code less and do more, this is it:
<!-- more -->
object Main {
def main(args: Array[String]): Unit = {
println("Starting...")
var i = 0
val n = 100
while (i < n) {
print(pad(i))
Thread.sleep(150)
i += 1
}
println("Done...")
}
def pad(i: Int) = {
var n = 0
val str = new StringBuilder
while (n < i) {
if (n == 50)
str.append(i + 1)
else
str.append(".")
n += 1
}
if (i < 50) {
while (n < 50) {
str.append(" ")
n += 1
}
str.append(i + 1)
}
if (i==99)
str.append("\n")
else
str.append("\r")
str.toString
}
}
