Using global variables

How to add variables?

Mandatory for using variable tags in slate is that you change all .md files to .md.erb. You folder structure can look like:

source/
    index.html.md.erb
includes/
    _want-to-use-var.md.erb

Do not forget to change the include section in the index file. And yes, you can ignore the _ from the include file. Slate needs this only for parsing.

includes:
 - want-to-use-var.md.erb

In config.rb create yourself a new section e.g. Global Variables and add the following lines.

# Global Variables
set :endpoint, 'https://my.endpoint.com'
config[:endpoint]

You have now created a global variables which you can use in your files with the following tag

<%= config[:endpoint] %>

An example for using variables could look like this:

Hello you want to access <%= config[:endpoint] %> !

Environment variables

To access environment variables, ENV can be used in config.rb. For example for a environment variable called MY_VAR:

set :my_var, ENV["MY_VAR"]
config[:my_var]
