Icon fonts are the new hotness. There are pros & cons, and if you want to waste your time reading terrible opinion pieces on all those reasons, Google away.
We're going to use a lovely tool called Hieroglyph. There's already a pretty intuitive readme file in the repo, but I hope to elaborate a little more on what was provided.
Open up Terminal and type
gem install hieroglyph. If for some reason you get an error and/or the install fails, update RubyGems by entering
sudo gem update --system into Terminal, then give it another shot. You can test to see if it works by simply entering
hieroglyph in terminal to generate an empty, dummy font.
You should get output similar to this:
~/Desktop » hieroglyph Setup: ImageMagick not detected - skipping character sheet Reading glyphs: Done! MyFont generated saved to /Users/Aaron/Desktop/MyFont.svg Single characters: Unicode characters:
Then just delete the generated SVG, in my case, on my Desktop.
Getting your icons ready
Open up Illustrator and create a new document sized 1000pt x 1000pt. We need to make sure that the icons are centered, and relatively the same size. Drag a horizontal guide so it sits 250 points from the top of the canvas. You can set this easily by dragging out a guide, then in your Illustrator toolbar setting the Y value to 250. You should also drag out a vertical rule with the X value of 500 so you have a vertical center showing.
Important: Make sure your icon is a compound path. If your canvas has more than one shape, it will cause issues with the font generation. You can make it a compound path by selecting all the shapes in the icon, and pressing CMD + 8.
Saving & Naming Convetion
Save your files as SVGs. Name them [key]-icon-name.svg. If you downloaded the template, you'll notice it's named [t]-twitter.svg. This will map the icon to the T key when our font is generated.
Let's get this thing generated. I've saved all my icons into a folder on my Desktop called glyphs. Go back into Terminal and browse to your Desktop by typing
Once we're there we can run
hieroglyph -n FontName -g path/to/glyphs -o destination/path.
Or if you've setup everything the way I have
hieroglyph -n Icons -g glyphs will generate the font on your desktop.
Your output will change depending on how many icons you've generated, but mine reads:
~/Desktop » hieroglyph -n Icons -g glyphs/ Setup: ImageMagick not detected - skipping character sheet Reading glyphs: Parsing 1 Parsing 2 Parsing 3 Parsing 4 Parsing 5 Parsing 6 Parsing 7 Parsing 8 Parsing 9 Done! Icons generated saved to /Users/Aaron/Desktop/Icons.svg Single characters: 1,2,3,4,5,6,7,8,9 Unicode characters: To create a full set of webfonts, upload to http://www.fontsquirrel.com/fontface/generator If you're having trouble uploading SVGs, try converting to a TTF first using http://www.freefontconverter.com
You can see a demo of the social font I just generated on my portfolio website.
Now that you've got your font in an SVG format, go ahead and run your new font through this font-face generator to get the other @font-face formats. Also make sure that you've clicked Expert and selected the custom subsetting option in the font-squirrel interface. If you're ballin' out of control, you might use FontXChange to generate the different formats instead.
Now you're ready to embed those files into your stylesheet and start serving some icons!
If you really want to do it up proper, GitHub's post about Octicons goes through their process in great detail.
If this is too much for you, fortunately there are tons of great services out there right now that really make this easier. There is the newly created Symbolset, which is a font of icons that advocates way better semantics than I've shown above. The Pictos font has a pretty wide array of icons, Pictos Server and Shifticons which are both damn fine services for doing this a lot faster. Finally, Doug linked me to IcoMoon which gives you a nice drag and drop interface for building a custom font
