DM Mono Ligaturized

DM Mono patched with Fira Code ligatures via Ligaturizer.

Setup

Install with Homebrew:

brew install --cask nanxstats/tap/font-dm-mono-ligaturized

Or install the ligaturized fonts from fonts/ using your OS font manager.

VS Code

In VS Code, press Cmd + Shift + P, search for Preferences: Open User Settings (JSON). In the opened settings.json, set font family to Liga DM Mono and enable ligatures:

"editor.fontFamily": "'Liga DM Mono', monospace",
"editor.fontLigatures": "'calt', 'liga'",
"terminal.integrated.fontFamily": "'Liga DM Mono', monospace",
"terminal.integrated.fontLigatures.enabled": true,

Open Ghostty settings (Cmd + ,) and set font family to Liga DM Mono:

font-family = Liga DM Mono

Press Cmd + Shift + , to reload the terminal with the new configuration.

Build

Run make in the repository root on macOS with git and Homebrew.

The Makefile will:

• Clone Ligaturizer (plus only the fonts/fira submodule) and DM Mono.
• Patch Ligaturizer options to target DM Mono and drop selected ligatures.
• Run the Ligaturizer build.
• Copy the ligaturized DM Mono font files into fonts/.
• Remove the cloned sources.

Dropped ligatures

These ligatures from Fira Code are intentionally omitted:

&&, ~@, \/, .?, ?:, ?=, ?., ??, ;;, /\
