This is a Go package for accessing data about an Opal card.

It is not anything particularly useful for users (yet); it is currently intended for programmers to use as a building block.

To get it, you need docutils, mercurial (hg command) and go programming language.

• docutils

https://pypi.python.org/pypi/docutils

mkdir docutilsetup
cd docutilsetup
curl -o docutils-docutils.tar.gz https://pypi.python.org/packages/source/d/docutils/docutils-0.12.tar.gz
gunzip docutils-docutils.tar.gz 
tar -xf docutils-docutils.tar 
cd docutils
sudo python setup.py install

• mercurial

http://mercurial.selenic.com/downloads

 make            # see install targets
 make install    # do a system-wide install
 hg debuginstall # sanity-check setup
 hg              # see help

• Go lanaguage

download and install GO programming lanaguage

http://golang.org/dl/

mkdir $HOME/go
export GOPATH=$HOME/go	
export GOROOT=/usr/local/go    	# default path, adjust it with your environment, if not installed in default path

go get github.com/bw57899/opal

You will need to put auth information in $HOME/.opal that looks like

cat ~/.opal
{"Username":"xxx","Password":"yyy"}

Don't forget to chmod 600 $HOME/.opal.

I plan to make it easier to pass to this package programmatically.

To do a quick test that will access your card information and print out its balance and recent transactions,

go test -v github.com/bw57899/opal
