Templating language script.MD

Simple HTML templating script

Usage

The script grabs all the HTML pages from a src folder, and the separate components from the components folder and injects the components from the folder into the pages.

Injecting a component in a page

src/page-1.html

={=components/component-name.component.html(prop-1=prop 1 value;prop-2=prop 2 value)=}=

This gets the component code from the specified components folder path and replaces it in the page code where the injection is written.

Injecting the given props in the component file

components/component-name.html

<p>-{-prop-1-}-</p>
