A placeholder is a type of data or object used to denote an empty field in the code.
In Lagmite, there are a few placeholders that are used within the documentation:
<module> is a placeholder that will require a module value, such as the module chem for chemistry.
<object> is a placeholder for objects, either text, numbers, or boolean values.
<number> is a placeholder specifically only used for numbers.
<type> is a placeholder for object types, such as those in Type Cards.
<variable> and <value> are placeholders for functions and math. A variable can be any string or character, and a value can be either a constant, number, or an operation.
<unit> is a special placeholder and holds a quantity and its respective unit.
<condition> is a placeholder for conditional notation formats. See Conditional Notation for more information.
