Scala is a simple scripting language. Just enter some scala code in a text file, and execute it with “scala file.scala“.
The below is a simple scala script to count the translated files, and also it’s size.
Basic Terminologies to be learnt before scripting are below :
1.Classes and type interfaces
2. How to work with collections
3. Higher Order Functions
4. Functional versus imperative : To var or not to Var
5. Default parameters and passing functions as arguments.

#!/bin/sh
exec scala "$0" "$@"

import java.io._
val docs = new File(".").listFiles
.filter(_.getName.endsWith(".textile")) // process only textile files
.map(new DocumentationFile(_))
val translated = docs.filter(_.isTranslated) // only already translated files
val translatedLength = translated.map(_.length).sum
val docsLength = docs.map(_.length).sum
println(
status("translated size", translatedLength, docsLength, (length) => asKB(length) )
)
println(
status("translated files", translated.length, docs.length)
)
def status(
title: String = "status",
current: Long, total: Long,
format: (Long) => String = (x) => x.toString): String = {
val percent = current * 100 / total
title + ": " + format(current) + "/" + format(total) + " " +
percent + "%" +
" (pending " + format(total - current) + " " +
(100-percent) + "%)"
}
def asKB(length: Long) = (length / 1000) + "kb"
class DocumentationFile(val file: File) {
val name = file.getName
val length = file.length
val isTranslated = (firstLine.indexOf("Esta página todavía no ha sido traducida al castellano") == -1)
override def toString = "name: " + name + ", length: " + length + ", isTranslated: " + isTranslated
def firstLine = new BufferedReader(new FileReader(file)).readLine
}
OUTPUT :
translated size: 256kb/612kb 41%
translated files: 24/64 37%
