A pattern is a description of the form that the lexemes of a token may take. In the case of a keyword as a token, the pattern is just the sequence of characters that form the keyword. For identifiers and some other tokens, the pattern is a more complex structure that is matched by many strings. Lexeme is a sequence of characters in the source program that is matched by the pattern for a token. A lexeme is a sequence of characters in the source program that matches the pattern for a token and is identified by the lexical analyzer as an instance of that token. In many programming languages, the following classes cover most or all of the tokens: 1. One token for each keyword. The pattern for a keyword is the same as the keyword itself. 2.
In a language supporting classes and inheritance, a class implicitly defines a mixin. The mixin is usually implicitâit is defined by the class body, and constitutes the delta between the class and its superclass. The class is in fact a mixin applicationâthe result of applying its implicitly defined mixin to its superclass. The term mixin application comes from a close analogy with function application. Mathematically, a mixin M can be seen as a function from superclass to subclass: feed M a superclass S, and a new subclass of S is returned. This is often written as M |> S in the research literature.
