What is TmpFile

A ruby gem to temporarily store data in a file with an appropriate extension

Why TmpFile was born

At Topspin we provide ArtistLink, a platform for musician to upload and share their songs. When a song contains cover art in the ID3 tag, we extract it to an image and process it to create a nice page background. We use TmpFile to temporarily extract the cover art data from the song into a file store its processed version.

Requirements

TmpFile has been tested on Ruby 1.8.7, 1.9.2, 1.9.3 and 2.0.0. No external libraries are required.

How to use from other programs

• Include tmp_file in the Gemfile of your bundled project and bundle install

• To store data in a temporary file and yield the file handle, run:

  TmpFile.open(data, mime_type) do |tmp_file|
    # do something with tmp_file
  end
