### ligature.el
If you're using a modern version of emacs, you might have ligature support built-in, via HARFBUZZ / Cairo. The [ligature.el](https://github.com/mickeynp/ligature.el) package adds infrastructure that uses Harfbuzz and Cairo to render ligatures from the fonts, just like in any other editor. Add the following to your `init.el` file:
```elisp
;; Enable the www ligature in every possible major mode
(ligature-set-ligatures 't '("www"))
;; Enable ligatures in programming modes
(ligature-set-ligatures 'prog-mode '("www" "**" "***" "**/" "*>" "*/" "\\\\" "\\\\\\" "{-" "::"
":::" ":=" "!!" "!=" "!==" "-}" "----" "-->" "->" "->>"
"-<" "-<<" "-~" "#{" "#[" "##" "###" "####" "#(" "#?" "#_"
"#_(" ".-" ".=" ".." "..<" "..." "?=" "??" ";;" "/*" "/**"
"/=" "/==" "/>" "//" "///" "&&" "||" "||=" "|=" "|>" "^=" "$>"

"<~" "<~~" "</" "</>" "~@" "~-" "~>" "~~" "~~>" "%%"))
(global-ligature-mode 't)
```
This is generally the easiest solution, but can only be used on macOS.
