FileUtil

statement

FileUtil is a small library for Scala to provide enrichment and utility methods for java.io.File. Where possible and useful, it tries to use the same method names as sbt, e.g. base and ext to obtain base file name and extension.

overview

Typically you will import the contents of package de.sciss.file. This includes a type alias File for java.io.File, a simple constructor file("path"), and enrichtments for File, which allow for example to construct files in the manner file("base") / "sub" / "sub".

    import de.sciss.file._              // import type alias File for java.io.File, and enrichments

    (userHome / "Desktop").isDirectory  // userHome is predefined, slash operator creates sub-files
    file(".").absolute                  // file(<string>) method creates file
    val x = file("foo/bar.baz")
    val (base, ext) = x.baseAndExt      // split name and extension
    x.replaceExt("pdf")                 // -> foo/bar.pdf
    val tmp = File.createTemp()         // temporary file (by default deleted upon exit)
    userHome.children(_.length > 4096)  // list files in directory, using filter predicate

Further methods on files such as relativize are available, as well as utility methods and object in the companion object, such as NameOrdering. See the API docs for a full overview. The regular Java methods on files are still available, such as .lastModified, .isFile, .isHidden, .length etc.
