# SassyIcons



> Flexible system to manipulate icons, SVG, PNG, sprites.  



NOTICE: This project is unmaintained and won't receive new features.  

Spritesheets automation helpers should better be handled by PostCSS plugins.



Works on top of compass sprite API.  

It was designed to easily switch between SVG and PNG while working with icons as background-images.  

So you have more granular control over which icons to use as SVG or PNG.  

SVG first with PNG sprite fallback, or PNG first with hidpi sprite support.  



Also managing several "thematic" sprites a breeze.  



*Best workflow used in conjunction with [grunt-svg2png](https://github.com/pascalduez/grunt-svg2png).*



*Online [Documentation](http://pascalduez.github.io/SassyIcons) (generated with SassDoc).*



## API



`sprite-map-create($name [, $spacing])`  

`icon($map, $sprite [, $offset, $format])`  

`icon-single($map, $sprite [, $format])`  

`icon-generated($map, $sprite [, $pos, $centered, $format])`



## Usage



### Requirements



* Sass ~> 3.3.0

* Compass ~> 1.0.0.rc.1



### Installation



#### Git



```

git clone [email protected]:pascalduez/SassyIcons.git

```



#### npm



```

npm install sassyicons --save

```



#### Bower



```

bower install SassyIcons --save

```



#### Compass extension



Since SassyIcons is dependant on Compass, this is the recommended installation and usage.



1. Add `gem 'SassyIcons', '~>0.1.0'` to your `Gemfile`

2. `bundle install --path .` (manage your gems in project dir, not globally)

3. Add `require 'SassyIcons'` to your `config.rb`

4. Import it in your stylesheets with `@import 'SassyIcons'`



### Configuration



```scss

// Default settings.

$icons-defaults: (



  // Space around sprites in generated spritemap.

  // Useful with `$offset` parameter.

  // This setting is global for all spritemaps.

  // Can be set per spritemap with the `$spacing` parameter.

  spacing: 0,



  // Main icons directory. `sprite-map-create()`, base for sub dirs.

  dir: "icons",



  // Name of the png sub-folders.

  dir-png: "png",



  // Name of the hidpi png sub-folders.

  dir-hidpi: "png_2x",



  // Scale of the hidpi pngs.

  hidpi-scale: 2,



  // Minimum resolution ratio used in the hidpi media query.

  hidpi-ratio: 1.3,



  // Whether to embed icons as data URI in the `icon-single()` mixin.

  single-embed: true,



  // Default file format unless overridden by parameter, svg | png.

  format: "svg",



  // Whether to support legacy browsers, svg fallback.

  legacy: true



);

```

Override default values in a new `$icons-settings` map.



## Usage



#### Example usage with [Compass](http://compass-style.org/help/tutorials/command-line)

```scss

// Import SassyIcons.

@import 'SassyIcons';



// Instantiate a new sprite-map from folder `icons/social`.

@include sprite-map-create(social, $spacing: 10px);



.icon--twitter {

  @include icon(social, "twitter");

}



.icon--twitter {

  @include icon-generated(social, "twitter", $format: "png");

}



```

```

bundle exec compass watch

```



## Roadmap



* More documentation

* `icon-generated()` and `generated()` Don't force absolute positioning.

* Rewrite `generated()` mixin

* `icon-generated()` configurable `calc()` fallback

* Helper mixin to work with `background-size`

* Support for SVG sprites ?

* Support for SVG stacks ?

* Try to further improve output CSS

* More control over print position in the stylesheet ?

* Abstract and move away from Compass sprites ?

* Move away from Modernizr classes ? Or make it an option.

* Clarify or remove the `@content` thing to pass additional rules to `.svg`.



## Future



This library used to address a specific need, at a specific moment. Although one

of its main feature is to bring granular control on how many icons you want to

inline, keep in mind that too many inlined SVG's, especially base64 encoded might

be a concern for performances.



There are a bunch of different techniques to integrate SVG icons, that you should

check out and evaluate before deciding on any.
