Real-time BART ETA on the command-line

bart

Purpose

Access real-time BART train departures using python and the Real Bart API. I always have a terminal window open, so I wrote this little command-line tool just so I don't have to open up a browser window to check the BART schedule.

Setup

Your very own BART API key is required and can be requested from api.bart.gov. Once obtained, name an environment variable named BART_API_KEY in your appropriate login script:

$ echo export BART_API_KEY=YOUR_KEY >> ~/.bash_profile

To use bart as I do in the terminal, alias bart.py by adding alias bart="~/bart/./bart.py" to your appropriate shell profile, or append by the following command:

$ echo alias bart="~/bart/./bart.py" >> ~/.bash_profile

To display the ETAs for north-bound trains at the 16th Street Mission station.

$ bart 16th n
