cool usage ideas

There's a list of great command line sparkline usage. And, you could always put it in your prompt...

sparkl (master√ history: ▂▅▇▂) >

future?

  • have switch for allowing/forcing 0-based lines
  • make logger use sparkl as module parameter
  • consider how to handle errors better - full trace might be good?
  • allow sparkline to be turned 90 degrees clockwise into horizontal bar chart?
