Terminology

To understand how Templater works, let's define a few terms:

• A template is a file that contains commands.
• A text snippet that starts with an opening tag <%, ends with a closing tag %> is what we will call a command.
• A function is an object that we can invoke inside a command and that returns a value (the replacement string)

There are two types of functions you can use:

• Internal functions. They are predefined functions that are built within the plugin. As an example, tp.date.now is an internal function that will return the current date.
• User functions. Users can define their own functions. They are either system command or user scripts.

Example

The following template contains 2 commands, calling 2 different internal functions:

Yesterday: <% tp.date.yesterday("YYYY-MM-DD") %>
Tomorrow: <% tp.date.tomorrow("YYYY-MM-DD") %>

We'll see in the next part the syntax required to write some commands.
