Overview

About this library

A simple Dropbox ( www.dropbox.com/ ) library to upload files, with no other gem dependencies. This library has been completely written from scratch, but ideas and logics are inspired from Dropbox Uploader ( jaka.kubje.org/software/DropboxUploader/ ).

Example

require "dropbox_uploader"
dropbox = DropboxUploader.new("[email protected]", "MyPassword")
dropbox.upload("localfile.txt", "/")

Known bugs

  • error check and recovery

  • non-ASCII file/remotedir name support
