Using Operator Mono with Fira Code ligatures in Atom.

1. Open your Atom's Stylesheet
   

2. Put this css

atom-text-editor {
  text-rendering: optimizeLegibility;
  -webkit-font-smoothing: antialiased;
  font-family: "Operator Mono";
  font-weight: 500;
  line-height: 1.7;
}

For Atom version < 1.13.x

atom-text-editor::shadow {
  .storage.type.function.arrow,
  .keyword.operator:not(.accessor),
  .punctuation.definition.entity.css {
    font-family: 'Fira Code';
  }

  .string.quoted,
  .string.regexp {
    -webkit-font-feature-settings: "liga" off, "calt" off;
  }
}

For Atom version >= 1.13.x

atom-text-editor.editor {
  .syntax--storage.syntax--type.syntax--function.syntax--arrow,
  .syntax--keyword.syntax--operator:not(.accessor),
  .syntax--punctuation.syntax--definition {
    font-family: "Fira Code";
  }

  .syntax--string.syntax--quoted,
  .syntax--string.syntax--regexp {
    -webkit-font-feature-settings: "liga" off, "calt" off;
  }
}

Save file and it's done.

Hi guys,

@orenmizr @chrishiste

I switched from VSCode to Atom recently and the tweak for having ligatures of Fira Code and Operator Mono for fonts is the following.
First download this package https://github.com/be5invis/vscode-custom-css

Then you create a basic css file somewhere on your computer, copy paste this snippet

.mtk5, .mtk8, .mtki, .mtk10 {
  font-family: 'Operator Mono';
  font-size: 16px;
  font-weight: normal;
  font-style: italic;
}

Then you'll have to go into VSCode settings panel and point to the newly created CSS file.
After that, open the command palette and just activate vscode-custom-css.

This should be the best way to do it.

WARN : Maybe Code will tell you that your Code version is broken, just don't care, it's because of vscode-custom package.

You are my hero. I hadn't even thought to do this. I use Operator Mono, and sorely miss my ligatures from Fira Code. Thank you so much! I already have a lot of tweaks in my CSS to user OM's script italics for more than just comments. Perfect addition.

How did you tweak yours please.?

Open Atom's stylesheet in Atom > Stylesheet..

Modify the sections to look like the following, the spans are the important part. You can find these class names by browsing through the editor in syntax of your choice using the developer tools (Option+Cmd+I).

`atom-text-editor.editor {

.syntax--storage.syntax--type.syntax--function.syntax--arrow,
.syntax--keyword.syntax--operator:not(.accessor),
.syntax--keyword.syntax--type,
.syntax--punctuation.syntax--definition {
font-family: "Fira Code";
}

span.syntax--keyword.syntax--control,
span.syntax--storage.syntax--type,
span.syntax--storage.syntax--modifier {
font-family: "Operator Mono";
font-style: italic;
}
`

What syntax theme and TextMate rules are you using? It's look nice. Thanks.
