What's the difference?

There are already some good solutions to use iconic font :
https://github.com/oblador/react-native-vector-icons
https://github.com/lwhiteley/react-native-android-iconify
https://github.com/corymsmith/react-native-icons

But ... these libraries are all require native code and/or native project config file modifications.
Believe me , it confusd many 'javascript' developers who are familar with 'native code'.
That's why i start this project .
No native code. Let's try to use pure javascript!

How

A font system is basically a 'character-graph' mapping.
In a web page,CSS rules deal with webfont like this:

<i class="fa-twitter">
==CSS rules==> .fa-twitter:before{content: "\f099";} 
                                 ==font system==>  a twitter graph

It's same process in React native except the CSS rules.That's what this project do.Mapping names to characters.

Besides I create a command tool to help transforming CSS file to these mapping module.

Run one command to generate the js module
iconmap -f test/font-awesome-v4.4.0.css -p '^\.fa-([a-z0-9-]+?):before$'
