A free programming font with cursive italics and ligatures
...When it comes to programming fonts, I prefer something thin and relatively condensed, but with a more informal, flowing, and human style for standouts like comments and certain keywords. In the past, I always ended up looking for something else after using a font for a while, because something didn't look right to me. So I started sketching and designing something myself. I wanted something that had friendly and distinct italics.
