Operator Mono Ligatures
These ligatures were custom created using Glyphs. There are even italic versions of the ligatures.
🎉 What's New in Version 2
All new redesigned ligatures with better hinting. Updated font generation to support advanced OpenType features like those found in Fira Code. For example, the cursor now moves inside the ligature. It also handles repeating characters properly.
With the awesome help from Mark Skelton, we now have the full set of ligatures for the following fonts. Thanks Mark, and thanks to all of you who have been patiently waiting for these ligatures to be completed.
- Operator Mono SSm Light/Light Italic
- Operator Mono SSm Book/Book Italic
- Operator Mono SSm Medium/Medium Italic
- Operator Mono SSm Bold/Bold Italic
- Operator Mono Light/Light Italic
- Operator Mono Book/Book Italic
🙏 Help Wanted
As noted above, v2 does not include all weights for Operator Mono. In order to update the other fonts, all the ligatures need to be redone. Unfortunately I just don't have the time to do that at the moment. If you have a Mac and are interested in helping, please let me know. I will even purchase a license to Gylphs Mini for you.

☑️ 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.
- The original Operator Mono font... of course.
- Python (v2.7+)
- Install fonttools from https://github.com/fonttools/fonttools
pip install fonttools
pip3 install fonttools
Once all the prerequisites have been installed, clone this repo or download latest release from Releases and unzip.
Next, copy your Operator Mono OpenType files into the
original folder. NOTE: Filenames must not include spaces. It should look like:
Finally, run the following commands to install npm dependencies and build the font files. The new font files will be placed in the
build folder. You can now install these fonts on your system.
npm install # Windows build # Linux/Mac ./build.sh
If you use Docker, you can also use the executable Docker image here. It handles all the prerequisite installation for you, you just need to:
- Clone the repo located here.
- Copy your Operator Mono OpenType files into the
- From the command line run:
docker-compose run --rm operator-mono-lig
The image will build and execute the conversion. The new font files will be generated into the
Configure Your Code Editor
You can now select the newly generated font in your code editor. Make sure you enable font ligatures and set the desired font weight if using Windows. The code block below shows what this might look like if using VS Code.
"editor.fontFamily": "OperatorMonoSSmLig-Book", "editor.fontLigatures": true, // for Windows "editor.fontFamily": "Operator Mono SSm Lig", "editor.fontLigatures": true, "editor.fontWeight": "500", // adjust for desired weight
🔧 Customize the generated font
By default, all available ligatures will be added to the generated font. However, if you don't like a particular
ligature, or would prefer to use an alternate glyph, you can create a
profiles.ini file in the
to configure how the font should be built.
You can create one or more profiles. Each profile will have a set of directives. You can specify alternate glyphs for a given ligature. You can also prevent a ligature from being added.
Each profile will be listed with
[profile name] (the first profile should be named default). The generated font will
include the profile name. For example
[Go] would generate the font: Operator Mono Lig Go. This way you can configure
a different set of ligatures for each language in your favorite code editor.
# name of profile (one or more sections, first should be name default) [default] # glyph=altglyph greater_equal.liga=greater_equal.2.liga # do not include glyph (add ! prefix) !equal_equal.liga # another optional section (will create a font named Operator Mono Lig Go) [Go] ... add custom directives for this font ...
😍 Thank You
Thanks to Hoefler&Co for making such an amazing font. It makes writing code truly pleasurable.
Thanks also to all of you for your kinds words of encouragement and feedback. I really appreciate it.
