Ligaturizer

This script copies the ligatures (glyphs and rendering information) from Fira Code into any other TrueType or OpenType font. (Note that the ligatures are scale-corrected, but otherwise copied as is from Fira Code; it doesn't create new ligature graphics based on the font you're modifying.) This repo contains a Fontforge python script that you can use to add the Fira Code ligatures to any font, as well as submodules for some popular coding fonts and another script for ligaturizing all of them at once. The font-weight will be inherited from the original file; the font name will be replaced with whatever you specified in --output-name. You can also use --prefix instead, in which case the original name will be preserved and whatever you put in --prefix will be prepended to it.
