Introduction

A filesystem toolset for Clojure:

  • work with paths (creating and manipulating).
  • work with the filesystem (files and directories crud and many predicates).
  • IO (clojure.java.io implementation for paths).

Install

Add the following dependency to your project.clj file:

funcool/datoteka {:mvn/version "RELEASE"}

Getting Started

The path and filesystem helper functions are all exposed under the datoteka.fs namespace, so let’s import it:

(require '[datoteka.fs :as fs])

This library uses JVM NIO, so under the hood, the java.nio.file.Path is used instead of classical java.io.File. You have many ways to create a path instance. The basic one is just using the path function:

(fs/path "/tmp")
;; => #path "/tmp"

As you can observe, the path properly prints with a data reader, so once you have imported the library, you can use the #path "/tmp" syntax to create paths.

The paths also can be created from a various kind of objects (such as URI, URL, String and seq’s):

(fs/path (java.net.URI. "file:///tmp"))
;; => #path "/tmp"

(fs/path (java.net.URL. "file:///tmp"))
;; => #path "/tmp"

(fs/path ["/tmp" "foo"])
;; => #path "/tmp/foo"

The path function is also variadic, so you can pass multiple arguments to it:

(fs/path "/tmp" "foo")
;; => #path "/tmp/foo"

(fs/path (java.net.URI. "file:///tmp") "foo")
;; => #path "/tmp/foo"

And for convenience, you can use the clojure.java.io api with paths in the same way as you have done it with java.io.File:

(require '[clojure.java.io :as io])

(io/reader (fs/path "/etc/inputrc"))
;; => #object[java.io.BufferedReader 0x203dc326 "java.io.BufferedReader@203dc326"]

(subs (io/slurp (fs/path "/etc/inputrc")) 0 20)
;; => "# do not bell on tab"

See namespace reference for the whole API overview.
