Gem Version Build Status Dependency Status Code Climate Coverage Status

Mt. Gox allows you to trade US Dollars (USD) for Bitcoins (BTC) or Bitcoins for US Dollars.

Installation

gem install mtgox

To ensure the code you're installing hasn't been tampered with, it's recommended that you verify the signature. To do this, you need to add my public key as a trusted certificate (you only need to do this once):

gem cert --add <(curl -Ls https://raw.github.com/sferik/mtgox/master/certs/sferik.pem)

Then, install the gem with the high security trust policy:

gem install mtgox -P HighSecurity

Executable

After installing the gem, you can get the current price for 1 BTC in USD by typing btc in your bash shell:

$ btc
50.00

Supported Ruby Versions

This library aims to support and is tested against the following Ruby implementations:

If something doesn't work on one of these interpreters, it's a bug.

This library may inadvertently work (or seem to work) on other Ruby implementations, however support will only be provided for the versions listed above.

If you would like this library to support another Ruby version, you may volunteer to be a maintainer. Being a maintainer entails making sure all tests run and pass on that implementation. When something breaks on your implementation, you will be responsible for providing patches in a timely fashion. If critical issues for a particular implementation exist at the time of a major release, support for that Ruby version may be dropped.
