CT Language Reference

Overview

A CT source file consists of a list of statements. Every statement ends with a semicolon. Comments can be included in the source by prefixing the comment text with //.

Declaring variables

A variable declaration statement begins with the variable's type followed by the variable's name, and then an optional assignment.

Variable names must start with either an alphabetic character or an underscore, and can contain:

• alphabetic characters
• numbers
• underscores
• dashes

Example variable declaration:

Color green = #00FF00;

Assigning Values to Variables

Values can be assigned to variables using the assignment operator (=). The value being assigned can be one of:

• A literal value
• A method call
• A member of a collection
• Another variable

Example of assigning a value to a variable:

green = rgba(0,255,0,1);

Literal Values

Literal RGBA hex colors

Literal hex colors are written as a hash (#) followed by either:

• 6 hex digits for RGB
• 8 hex digits for RGBA

Example:

#00FF00;

Literal strings

String literals are any text enclosed in double quotes. A double quote character can be included in a string by escaping it with a backslash.

Example:

"a string"

Literal collections

Collections start with { and end with }.

Example:

{
    name = "value";
    green = #00FF00;
}

Literal templates

Templates start with {{{ and end with }}}

Example:

{{{
"name": %value%
}}}

Method Calls

The return value of static methods defined in Java classes can be assigned to a variable. The method must be imported before it can be called.

Example:

rgba(0,255,0,1)

Member of a Collection

Example:

primary.green
