Apply OpenType Features in IDE’s

[Mark2Mark]

I want to collect the ways with which certain font features can be enabled/disabled in different IDE’s

Feel free to add your favourite IDE here.

VSCode

e.g.

"editor.fontLigatures": "'ss01', 'ss02', 'ss03', 'ss04', 'ss05', 'ss06', 'zero', 'onum'"

or

    "editor.fontFamily": "Gintronic"    
    "editor.fontLigatures": true,
    "[cpp]": {
        "editor.fontLigatures": "'ss01', 'ss02'",
    },
    "[javascript]": {
        "editor.fontLigatures": "'ss01'",
    }, 

Source. It seems you can apply the settings language based. I find the name editor.fontLigatures a little misleading, as ligatures are only a subset of the font features, but it handles the font features as a whole.

Note

Please note that Gintronic currently does not (yet) have coding ligatures. See #13

Kitty Terminal Emulator

The Kitty terminal emulator specifies font variants like so:

font_features Gintronic-Regular +ss01 +ss02 +onum
font_features Gintronic-Black   +ss01 +ss02 +onum

and so on. Note that Kitty uses the "formal" name of the font for specifying font features, which you can specify in the terminal using the kitty +list-fonts --psnames command.

Wezterm

The Wezterm terminal emulator is configured using Lua, with stylistic sets applied like so:

CONFIG = {}

CONFIG.harbuzz_features = { "ss01", "ss02", "onum" }

return CONFIG

Or at least, that's how I style it.

Emacs 28+

As far as I can tell, stylistic set and character variants have to be baked-in to the font to get them to display properly in Emacs. Ligatures (which if I interpret it correctly are also part of the OpenType features, although I have to admit I don't know much about the internals of fonts) are enabled by using the ligatures.el package from MELPA, and specifying the character REGEXes to check:

(use-package ligature
  [...]
  :config
  (ligature-set-ligatures 'prog-mode '("->", "|>", [...])); enable these ligatures only for code
  (ligature-set-ligatures 't '("www")); This ligature is global
)

I'm relatively new at Emacs so I might be mistaken, but this the advice I was most recently able to find.

Thank you for the lovely font ❤️

Thanks so much for your input! I really appreciate it. Glad you like the font.

Also you understand correctly that ligatures are part of the OpenType Features. They are enabled/disabled the same way. However there are different approaches when making the font, where you can specify which ligatures will always show and which will show on user’s discretion.

The above configuration doesn't seem to enable ligature for me. I wonder which font features should I enable?

[Mark2Mark]

Hey @dongz9, which ligatures are you achieving to see? The current version of Gintronic does not (yet) have ligatutes. See #13

It will be nice to include ligatures similar to Fira Code, MonoLisa and JetBrains Mono.
