All of the methods I've found for enabling font ligatures do not work in the 2.0.0 series of releases. Is there an example of the correct CSS for 2.0.0?

@mapitman - Hi Mark - according to comments on #914, hyper does not support ligatures due to current limitations with xterm3. That project still has ligatures as an open feature request according to the link below

Thanks @chaseleinart . I'll go ahead and close this issue then.

Looks like they published an official addon to enable font ligatures support: https://github.com/xtermjs/xterm-addon-ligatures

@SirWindfield Great catch! I just built hyper locally with that addon. I had to precompile the library (because it's typescript) and I ended up throwing it in the lib directory, but I was able to get ligatures working.

If I can figure out a better way to include this change and get it building, I'll submit a PR!

@mapitman We may want to reopen this now that it's been shown to work with the addon from xterm.

@BenMcH you can use https://www.npmjs.com/package/hyper-font-ligatures which adds the xterm plugin for you 🎉

Installation

Using the built-in Hyper plugin manager

$ hyper i hyper-font-ligatures

Using the .hyper.js file

Open the ~/.hyper.js file using your favorite text editor and edit the
plugins array to include hyper-font-ligatures:

plugins: ['hyper-font-ligatures'],

In both cases, a 'Full Reload' (View -> Full Reload) is required.

Keep in mind this is very much in the early stages as it's using a beta build of the ligatures addon. We're still finalized on the API exposed in xterm.js, which means this might break at one point (and need xterm-addon-ligatures updated).
