Better technical typography
10 Nov 2023
I put a lot of emphasis on how my workspace looks. I believe in beauty as a form of function. That’s why i usually spend a lot of time customizing the tools i use.
The terminal: Kitty
My current setup is composed of Kitty, a very simple terminal emulator, paired with Recursive.
I know there are lots of options out there, like the macOS native terminal emulator or the very ubiquitous iTerm, as well as Warp.
While all those tools are great, only Kitty is able to address all the main features I need:
- Fast response for use with Neovim
- Support for font ligatures
- Great font tools and extensible documentation on those
iTerm is very slow to use with Neovim. It just does not keep up with the tool and drains a lot of battery when doing so. Warp is very fast and snappy, but to this date, it still does not support font ligatures.
Kitty has an incredible font rendering engine. Though the configuration is not as easy as in other terminals, as a Vim user you’ll feel at home, plus it’s quite well documented. This terminal allows you to change fonts per style. That is, you can choose a completely different font for bold and for normal, or for italics. It’s not really obvious why one would do that, but with fonts like Recursive, this is incredibly helpful.
On top of that, Kitty uses basically no battery, as it’s heavily optimized for laptop use. Quite crazy this is a completely free, open source project.
Recursive comes in two main flavours: Casual and Linear, and you can download both separately from the Google Fonts page.
By downloading both, we can do something like this in our
font_family Recursive Monospace Medium bold_font Recursive Monospace Casual ExtraBold italic_font Recursive Monospace Casual Medium bold_italic_font Recursive Monospace Casual ExtraBold
We are telling kitty to use the linear “normal” one in normal text, but when text is bold, use the casual one. Same goes with the italics. This adds an incredibly tasty flavour to the code if your terminal allows for it.
Particularly within Neovim, I am using the Catppuccin theme which also enables italics in particular places, like function arguments. Notice how the selected text also becomes bold and
We can also enable ligatures directly accessing OpenType features independently on each font we declared before:
font_features RecursiveMonospace-Medium +zero +dlig
This makes it so that the
0 character is slashed (
+zero ) and the (D)iscretionary (Lig)atures
+dlig are enabled in the medium weight of the linear font.
