# Operator Mono Ligatures

This project will generate new OpenType fonts for [Operator Mono](https://www.typography.com/fonts/operator/styles/) that includes ligatures similar to
those found in the popular [Fira Code](https://github.com/tonsky/FiraCode) font.

These ligatures were custom created using [Glyphs](https://glyphsapp.com/). 
There are even italic versions of the ligatures. 

## Take the poll

Which font weight of Operator Mono do you use? Also note difference between Screen Smart (SSm) and regular version. This will help prioritize the order of development.

>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` (for Mac users it's better run `pip3 install fonttools` - [info](https://stackoverflow.com/a/33416270/3191011))
* Node.js (**version 7.6+ for async/await support**)

## How to Install

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

2. From the command line, run:

```
npm install
```

3. Copy your *Operator Mono* OpenType files into the `original` folder.
- **NOTE**: File names must strictly be of the form `OperatorMono-[Book/BookItalic/Medium/MediumItalic].otf`.

4. 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.
