0xproto

0xProto is a programming font designed around source code legibility. Its stated goal is to reduce ambiguity between similar-looking characters, which the project frames as a way to help avoid errors while reading and writing code. The font is distributed as downloadable font files and is licensed under the SIL Open Font License 1.1. Key design features described in the README: 1. Clear differentiation. The font is built to make similar-looking letters easier to tell apart, reducing ambiguity in code. 2. Legibility at small sizes. Character interiors are kept wide enough to remain visible at the small font sizes common in editors and terminals. It also supports Texture Healing, a technique (also used by GitHub's monaspace) that slightly widens naturally wide characters such as `m` when they sit next to narrow characters like `i` and `l` or punctuation, while staying within monospace width. 3. More whitespace. The typeface uses distinctive letter shapes to balance the uneven dark/light distribution typical of monospaced fonts. 4. Ligatures that do not deform shape. The project deliberately avoids ligatures that change the meaning or form of symbols, such as turning `!=` into `≠`. It notes that users who prefer such programming ligatures may prefer Fira Code instead. OpenType features: the Italic family offers a Script Variant via stylistic set `ss01`, which changes some characters to script forms. The README links to instructions for enabling stylistic sets in Visual Studio Code and other tools. Installation: download the font files from the project's releases, unzip, and install. On macOS, drag the font file into Font Book or another font manager; on Windows, right-click the file and choose Install. Using it in Visual Studio Code: open Settings, go to Text Editor -> Font -> Font Family, and enter `"0xProto"` in quotation marks. To enable ligatures, go to Text Editor -> Font -> Font Ligatures, click Edit in settings.json, and set `"editor.fontLigatures"` to `true`. The README also answers common questions: the font is free and open source, with details in the LICENSE file; releases are available on GitHub; "0xProto NL" refers to the no-ligatures variant; and "Zx Proto" is the same as 0xProto. Users are invited to open issues for further questions.
