# helix-sev

Helix extensions which SevereOverfl0w likes:

* A version of `$d` that allows including classes and ids in the string as a convenient shorthand [[helix#81](https://github.com/lilactown/helix/issues/81)]
* A macro which generates a custom defnc & defnc- with your provided default options
* My preferred defnc/defnc- with it's features
