Here's another vote for Source Code Pro. It's an amazingly attractive font. I'm glad I discovered it.

Trying "Source Code Pro Light," it reminds me of one of the fonts on Solaris CDE but a bit more sensible.

Aha! You're right...

Does it show more lines than consolas in the editor? I just measured Hack with Consolas (9pt) in VS.NET, and Hack shows 54 lines, Consolas 65 (and for reference, lucida console 131). The page you linked to shows the typeface, which is nice, but it's hard to measure whether it's a font that's going to lead to more lines or less lines in the editor.

I switched from Consolas to Source Code Pro after I switched to a 4k monitor. On a 1080p display, I think I still prefer Consolas, but Source Code Pro is absolutely beautiful on a high-dpi screen.

I use source code pro lite on everything that requires monospaced fonts now. I use source sans pro a lot in documents / email.

Yeah, this is my go-to as well.

I've been using Source Code Pro Light for quite a while. It's great.

Mine too, especially for the light version for non-retina OSX!

I'm particularly fond of semi-bold. I find light is too narrow for my vision and taste. After a while of using the light version, it starts to blur together, but semibold works well. But my wife uses light and regular on her high DPI Lenovo.

Well, I'm glad there are these variations for peoples preferences, I wish multiple font wights was a more common option.

I love it too, using it on Xcode and iTerm

Can you set iTerm to use Light as the Regular font and then use Regular font as the Bold font?
