Add a custom Live-Template macro

Hi community,

i try to add a custom live template macro.

i found this post: http://stackoverflow.com/questions/12156205/how-can-i-add-custom-expression-functions-for-live-templates-in-intellij
and an easy example for the existing CapitalizeMacro: https://github.com/JetBrains/intellij-community/blob/3f7e93e20b7e79ba389adf593b3b59e46a3e01d1/platform/lang-impl/src/com/intellij/codeInsight/template/macro/CapitalizeMacro.java

i want a macro that rewrite the given string (dashed) into camelCase

example:
foo-bar become fooBar

i think i can write a little macro based on the example from CapitalizeMacro.

BUT. my question is, how can i get this custom macro into my PHPStorm? i am working on a windows machine.

Thanks for Help
