Code in TypeDown

TypeDown supports embedded code scripting capabilities, allowing you to include dynamic elements and logic within your documents. TypeDown's scripting syntax provides a flexible way to enhance your documents with programmatic functionality.

INFO

• Code statements begin with the hash (#) character
• Comments begin with the percent (%) character
• Different data types are supported (strings, integers, floats, booleans)
• Function calls use standard syntax: #functionName(arguments)
• Variables can be created using #let expressions

Basic Code Syntax

A code statement in TypeDown is created using the hash (#) character followed by your code expression.

#let greeting = "Hello World"
#print(greeting)

Comments

Comments can be added to your code using the percent (%) character. Comments are ignored during execution.

#let x = 10  % This is a comment explaining the code
% This entire line is a comment

Data Types

TypeDown scripting supports various data types for use in your code:

#let myString = "This is a string"         % String type
#let myInteger = 42                        % Integer type
#let myFloat = 3.14159                     % Float type
#let myBoolean = true                      % Boolean type (true or false)
#let myList = List(1, 2, 3, 4)             % List type
#let myMap = Map(name: "peter", age: 32)   % Map type with `name` of type String and `age` of type Integer

Function Calls

You can call functions using standard syntax:

#figure(caption: "My Caption")[ Figure body content ]
#underline("Underline this text")

Variable Assignment

Variables are declared and assigned using the let keyword:

#let username = "user123"
#let itemCount = 5
#let totalPrice = calculatePrice(itemCount)

Multiple variables can be declared like so:

#let username = "user123"; itemCount = 5; totalPrice = calculatePrice(itemCount);

Content Blocks

Multiline markup content can be enclosed in square brackets:

#renderTemplate([
    This is a multiline
    content block that will be
    processed by the renderTemplate function
])
