Fira Code iScript is a font hybrid with ligatures as well as a nice cursive style font for italics, allowing a distinct visual difference for keywords and comments (with appropriate style theme applied). I later also created a similar font hybrid with a more-readible script font that you can find here.
The regular and bold fonts (and where the ligatures are from) are from Fira Code; the italic is from Script12.
Here's what's changed from the origianl Fira Code iScript.
The meta data has been tweeked so that more applications recognize the italic font (it previously wasn't marked as italic).
The font is now correctly monospaced and is a matching width to Fira Code
I'm really picky so I didn't like the following characters.
This was the latest Fira Code font that I've updated to. Thanks @tonsky !
Download the distribution folder and install the ttf fonts in there. Make sure you have an editor theme that supports both italics and ligature. Finally, in your editor, set the font to 'Fira Code iScript' and set ligatures to true.
This is all based on the original Fira Code iScript. Thanks @kencrocken !
