Add ligatures to any coding font!

This repo contains 2 things:

1. Programming fonts with ligatures added (in output-fonts/), including:

• Anonymous Pro
• CamingoCode
• Cousine
• DejaVu Sans Mono
• Droid Sans Mono
• edlo
• Hack
• Inconsolata & Inconsolata-g
• IBM Plex Mono: Regular, Semibold
• Meslo (LGL, LGLDZ, LGM, LGMDZ, LGS, LGSDZ)
• Oxygen Mono
• Roboto Mono
• SF Mono: Regular, Semibold
• Ubuntu Mono

2. A fontforge python script (ligaturize.py) that adds the ligatures from Fira Code to a font without ligatures

Here's a couple examples of the fonts generated: SF Mono with ligatures (note the != and ->):

Credit
This awesome script was written by IlyaSkriblovsky for adding ligatures to Deja Vu Sans Mono (dv-code-font). I made a few changes to generalize the script so that it works for any font, so that I could add ligatures to my favorite fonts.

Using the Fonts: See the FiraCode README for a list of supported editors.

Script: This script requires FontForge python bindings. For Debian/Ubuntu they are available in python-fontforge package. For macOS, they are available via brew (brew install fontforge).

1. Move/copy the font you want to ligaturize into input-fonts/
2. Run the script: $ fontforge -lang=py ligaturize.py
3. You'll be prompted for the name of the font, and the name for the generated font. Example:

❯ fontforge -lang=py ligaturize.py
    ...
Enter the source font filename (including extension): RobotoMono-Regular.ttf
Enter a name for your ligaturized font -- or press ENTER to use the same name: <PRESS ENTER>
    ...
Generated ligaturized font Roboto Mono L in ligaturized-fonts/RobotoMono.ttf

❯ fontforge -lang=py ligaturize.py
    ...
Enter the source font filename (including extension): RobotoMono-Regular.ttf
Enter a name for your ligaturized font -- or press ENTER to use the same name: RobotoMonoL
    ...
Generated ligaturized font Roboto Mono L in ligaturized-fonts/RobotoMonoL.ttf

If you don't provide a name for the new font, it will have the same name as the input font.
