It does not set the mono flag, so I had to try it with GTK2 gvim to even load the font:

  % ttfmono MonaspaceArgon-Regular.otf 
  monospaced flag = 0
  (0 = variable-width, otherwise = monospaced)

Sadly I think that because of that flag it does not enable ligatures.

I was able to see ligatures and text healing in vim running in a patched st* though. I really like it thanks! The text healing only moves the line subtly as I type and when I cursor over there are no droppings from the widened 'm' for example. It's well thought-out for code.

If I could ask for a feature it would be to select some variants, like angular 0 with reverse slash or to leave the ! in the != ligature. To see what I mean: https://github.com/be5invis/Iosevka/blob/main/doc/stylistic-...

Are you sure? On OSX they're showing up in Font Book under "Fixed Width" fonts. I'm using whatever version was released today, so that might be a recent fix.

Just checked, don't show-up in under fixed, monaspace 1.000 macos 13.6.1

Probably font book decides it's monospaced when verifying the font. I doubt FreeType would consider it mono (that's what matters for GTK2). What's fc-list -v show on your machine under fixed?
