Fondue Tokens

This example code is bare-bones to show you what this framework can do. If you have the style-dictionary module installed globally, you can cd into this directory and run:

style-dictionary build

You should see something like this output:

Copying starter files...

Source style dictionary starter files created!

Running `style-dictionary build` for the first time to generate build artifacts.

Good for you! You have now built your first style dictionary! Moving on, take a look at what we have built. This should have created a build directory and it should look like this:

├── README.md
├── config.json
├── tokens/
│   ├── color/
│       ├── base.json
│       ├── font.json
│   ├── size/
│       ├── font.json
├── build/
│   ├── android/
│      ├── font_dimens.xml
│      ├── colors.xml
│   ├── compose/
│      ├── StyleDictionaryColor.kt
│      ├── StyleDictionarySize.kt
│   ├── scss/
│      ├── _variables.scss
│   ├── ios/
│      ├── StyleDictionaryColor.h
│      ├── StyleDictionaryColor.m
│      ├── StyleDictionarySize.h
│      ├── StyleDictionarySize.m
│   ├── ios-swift/
│      ├── StyleDictionary.swift
│      ├── StyleDictionaryColor.swift
│      ├── StyleDictionarySize.swift

If you open config.json you will see there are 5 platforms defined: scss, android, compose, ios, and ios-swift. Each platform has a transformGroup, buildPath, and files. The buildPath and files of the platform should match up to the files what were built. The files built should look like these:

Android

<!-- font_dimens.xml -->
<resources>
  <dimen name="size_font_small">12.00sp</dimen>
  <dimen name="size_font_medium">16.00sp</dimen>
  <dimen name="size_font_large">32.00sp</dimen>
  <dimen name="size_font_base">16.00sp</dimen>
</resources>

<!-- colors.xml -->
<resources>
  <color name="color_base_gray_light">#ffcccccc</color>
  <color name="color_base_gray_medium">#ff999999</color>
  <color name="color_base_gray_dark">#ff111111</color>
  <color name="color_base_red">#ffff0000</color>
  <color name="color_base_green">#ff00ff00</color>
  <color name="color_font_base">#ffff0000</color>
  <color name="color_font_secondary">#ff00ff00</color>
  <color name="color_font_tertiary">#ffcccccc</color>
</resources>

Compose

object StyleDictionaryColor {
  val colorBaseGrayDark = Color(0xff111111)
  val colorBaseGrayLight = Color(0xffcccccc)
  val colorBaseGrayMedium = Color(0xff999999)
  val colorBaseGreen = Color(0xff00ff00)
  val colorBaseRed = Color(0xffff0000)
  val colorFontBase = Color(0xffff0000)
  val colorFontSecondary = Color(0xff00ff00)
  val colorFontTertiary = Color(0xffcccccc)
}

object StyleDictionarySize {
  /** the base size of the font */
  val sizeFontBase = 16.00.sp
  /** the large size of the font */
  val sizeFontLarge = 32.00.sp
  /** the medium size of the font */
  val sizeFontMedium = 16.00.sp
  /** the small size of the font */
  val sizeFontSmall = 12.00.sp
}

SCSS

// variables.scss
$color-base-gray-light: #cccccc;
$color-base-gray-medium: #999999;
$color-base-gray-dark: #111111;
$color-base-red: #ff0000;
$color-base-green: #00ff00;
$color-font-base: #ff0000;
$color-font-secondary: #00ff00;
$color-font-tertiary: #cccccc;
$size-font-small: 0.75rem;
$size-font-medium: 1rem;
$size-font-large: 2rem;
$size-font-base: 1rem;

iOS

#import "StyleDictionaryColor.h"

@implementation StyleDictionaryColor

+ (UIColor *)color:(StyleDictionaryColorName)colorEnum{
  return [[self values] objectAtIndex:colorEnum];
}

+ (NSArray *)values {
  static NSArray* colorArray;
  static dispatch_once_t onceToken;

  dispatch_once(&onceToken, ^{
    colorArray = @[
[UIColor colorWithRed:0.800f green:0.800f blue:0.800f alpha:1.000f],
[UIColor colorWithRed:0.600f green:0.600f blue:0.600f alpha:1.000f],
[UIColor colorWithRed:0.067f green:0.067f blue:0.067f alpha:1.000f],
[UIColor colorWithRed:1.000f green:0.000f blue:0.000f alpha:1.000f],
[UIColor colorWithRed:0.000f green:1.000f blue:0.000f alpha:1.000f],
[UIColor colorWithRed:1.000f green:0.000f blue:0.000f alpha:1.000f],
[UIColor colorWithRed:0.000f green:1.000f blue:0.000f alpha:1.000f],
[UIColor colorWithRed:0.800f green:0.800f blue:0.800f alpha:1.000f]
    ];
  });

  return colorArray;
}

@end

Pretty nifty! This shows a few things happening:

1. The build system does a deep merge of all the token JSON files defined in the source attribute of config.json. This allows you to split up the token JSON files however you want. There are 2 JSON files with color as the top level key, but they get merged properly.
2. The build system resolves references to other design tokens. {size.font.medium.value} gets resolved properly.
3. The build system handles references to token values in other files as well as you can see in tokens/color/font.json.

Now let's make a change and see how that affects things. Open up tokens/color/base.json and change "#111111" to "#000000". After you make that change, save the file and re-run the build command style-dictionary build. Open up the build files and take a look.

Huzzah!

Now go forth and create! Take a look at all the built-in transforms and formats.
