Operator Mono Ligatures

This project will generate new OpenType fonts for Operator Mono that includes ligatures similar to those found in the popular Fira Code font.

These ligatures were custom created using FontForge. There are even italic versions of the ligatures.

NOTE: Because Operator Mono is not a free font, you must have the original font files. This utility will merge the ligature definitions into a copy of the original font. The new font family is named Operator Mono Lig so you can install it side-by-side with the original font.

Prerequisites

• The original Operator Mono font... of course.
• Install fonttools from https://github.com/fonttools/fonttools
  • Install Python
  • Run: pip install fonttools
• Node.js (version 7.6+ for async/await support)

How to Install

Once all the prerequisites have been installed, clone this repo.

From the command line, run:

npm install

Copy your Operator Mono OpenType files into the original folder.

From the command line, run:

Windows

build

Linux/Mac

build.sh

This will generate the new font files in the build folder. You can now install these fonts on your system.
