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.

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 git@github.com: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.

Add gem 'SassyIcons', '~>0.1.0' to your Gemfile
bundle install --path . (manage your gems in project dir, not globally)
Add require 'SassyIcons' to your config.rb
Import it in your stylesheets with @import 'SassyIcons'

Configuration

// 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

// 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.
