### Intro

Icon-font generation, easy to use and highly configurable.

It also generates TypeScript types, JSON maps of the generated code-points, allowing for a great deal of different usages, e.g. integrating with React type-safe icon components or integration on mobile apps by just combining TTF and JSON generation.

### Install

```bash
npm install -g fantasticon
```

## Use

### Quick usage

```bash
fantasticon my-icons -o icon-dist
```

### Command-line

**Note:** Not all options can be specified through the command line - for `formatOptions`, `pathOptions`, `getIconId` and `templates` use a [configuration file](#configuration-file) or the JavaScript [API](#api).

```
Usage: fantasticon [options] [input-dir]

Options:
  -V, --version                output the version number
  -c, --config <value>         custom config path (default: .fantasticonrc | fantasticonrc | .fantasticonrc.json | fantasticonrc.json | .fantasticonrc.js | fantasticonrc.js)
  -o, --output <value>         specify output directory
  -n, --name <value>           base name of the font set used both as default asset name (default: icons)
  -t, --font-types <value...>  specify font formats to generate (default: eot, woff2, woff, available: eot, woff2, woff, ttf, svg)
  -g --asset-types <value...>  specify other asset types to generate (default: css, html, json, ts, available: css, scss, sass, html, json, ts)
  -h, --font-height <value>    the output font height (icons will be scaled so the highest has this height) (default: 300)
  --descent <value>            the font descent
  --normalize [bool]           normalize icons by scaling them to the height of the highest icon
  -r, --round [bool]           setup the SVG path rounding [10e12]
  --selector <value>           use a CSS selector instead of 'tag + prefix' (default: null)
  -p, --prefix <value>         CSS class prefix (default: icon)
  --tag <value>                CSS base tag for icons (default: i)
  -u, --fonts-url <value>      public URL to the fonts directory (used in the generated CSS)
  --debug                      display errors stack trace (default: false)
  --silent                     run with no logs (default: false)
  --help                       display help for command
```

### Configuration file

Some options (specifically, `formatOptions`, `pathOptions` and `getIconId`) cannot be passed to the CLI directly.

To have more control and better readability, you can create a simple configuration file.

By default, `fantasticon` will look for one of following files in the working directory:

```
.fantasticonrc | fantasticonrc | .fantasticonrc.json | fantasticonrc.json | .fantasticonrc.js | fantasticonrc.js
```

You can specify a custom `--config` option with your configuration file path.

Here's an example `.fantasticonrc.js`:

```js
module.exports = {
  inputDir: './icons', // (required)
  outputDir: './dist', // (required)
  fontTypes: ['ttf', 'woff', 'woff2'],
  assetTypes: ['ts', 'css', 'json', 'html'],
  fontsUrl: '/static/fonts',
  formatOptions: {
    // Pass options directly to `svgicons2svgfont`
    woff: {
      // Woff Extended Metadata Block - see https://www.w3.org/TR/WOFF/#Metadata
      metadata: '...'
    },
    json: {
      // render the JSON human readable with two spaces indentation (default is none, so minified)
      indent: 2
    },
    ts: {
      // select what kind of types you want to generate (default `['enum', 'constant', 'literalId', 'literalKey']`)
      types: ['constant', 'literalId'],
      // render the types with `'` instead of `"` (default is `"`)
      singleQuotes: true,
      // customise names used for the generated types and constants
      enumName: 'MyIconType',
      constantName: 'MY_CODEPOINTS'
      // literalIdName: 'IconId',
      // literalKeyName: 'IconKey'
    }
  },
  // Use a custom Handlebars template
  templates: {
    css: './my-custom-tp.css.hbs'
  },
  pathOptions: {
    ts: './src/types/icon-types.ts',
    json: './misc/icon-codepoints.json'
  },
  codepoints: {
    'chevron-left': 57344, // decimal representation of 0xe000
    'chevron-right': 57345,
    'thumbs-up': 57358,
    'thumbs-down': 57359
  },
  // Customize generated icon IDs (unavailable with `.json` config file)
  getIconId: ({
    basename, // `string` - Example: 'foo';
    relativeDirPath, // `string` - Example: 'sub/dir/foo.svg'
    absoluteFilePath, // `string` - Example: '/var/icons/sub/dir/foo.svg'
    relativeFilePath, // `string` - Example: 'foo.svg'
    index // `number` - Example: `0`
  }) => [index, basename].join('_') // '0_foo'
};
```

### API

#### Simple usage

```js
import { generateFonts } from 'fantasticon';

generateFonts().then(results => console.log('Done', results));
```

#### Options

```js
import { generateFonts } from 'fantasticon';

generateFonts({
  name: 'icons',
  fontTypes: [FontAssetType.EOT, FontAssetType.WOFF2, FontAssetType.WOFF],
  assetTypes: [
    OtherAssetType.CSS,
    OtherAssetType.HTML,
    OtherAssetType.JSON,
    OtherAssetType.TS
  ],
  formatOptions: { json: { indent: 2 } },
  templates: {},
  pathOptions: {},
  codepoints: {},
  fontHeight: 300,
  round: undefined, // --
  descent: undefined, // Will use `svgicons2svgfont` defaults
  normalize: undefined, // --
  selector: null,
  tag: 'i',
  prefix: 'icon',
  fontsUrl: null
}).then(results => console.log(results));
```

#### Organising icons

Icon names and className will be generated from a slug of the relative path + basename of each `.svg` file found in the input directory.

This allows arranging your icons in namespaces, which can be useful if a project uses a large number of icons.

Considering the following `./icons` input directory:

```
icons
├── logo.svg
├── social
│   ├── facebook.svg
│   └── twitter.svg
└── symbol
    └── chevron
        ├── left.svg
        └── right.svg
```

Running `fantasticon ./icons -o dist` will generate a font-set with the following Icon IDs / CSS selectors:
And the generated icon IDs would be:

| Icon ID                | CSS selector                 |
| ---------------------- | ---------------------------- |
| `social-facebook`      | `.icon.icon-social-facebook` |
| `social-twitter`       | `.icon.icon-social-twitter`  |
| `symbol-chevron-left`  | `.icon.icon-chevron-left`    |
| `symbol-chevron-right` | `.icon.icon-chevron-right`   |

You can provide a `getIconId` function via the configuration file to customize how the icon IDs / CSS selectors are derived from the filepath. The function will receive relative paths to the icon and the input directory as arguments, and must return a unique string to be used as the ID.
