Features

• HTML output for use in browser

Installation

If you just want to use it, take a look at the public/index.html file. It is a good start to use it. Additionally, you need the public/presentationmaker.js script. The CSS is optional, but encouraged. It provides all the needed boilerplate to get you running.

Development

If you want to help with development or want to see live updates if you change your xml, check out the project and use

npm install
npx webpack serve

and a browser pointing to localhost:8080

Usage

The main presentation file is pure XML with a <presentation> root node. Below this there are

<defintions>

These are in the form of <name>value<name> Later "name" can be used via ${name} in the templates/pages

<modules>

Similar to the definitions, a <module_name>...</module_name> Creates a module that can be used later. The module itself can use other previously defined modules as <module_name optional="value">optional inner content</module_name> The parameter you add during use will be available to the module as ${optional} Existing internal modules are
