Questions tagged [token]

A token is a string of characters, categorized according to the rules as a symbol (e.g., IDENTIFIER, NUMBER, COMMA). The process of forming tokens from an input stream of characters is called tokenization, and the lexer categorizes them according to a symbol type. A token can look like anything that is useful for processing an input text stream or text file.

A token is the smallest part of an input text with a meaning. A token may be a single character, a symbol, a word or anything that is useful for processing an input text. Tokens are used in processing programming languages or natural languages.

The process of forming tokens from an input stream is called tokenization or lexical analysis. A program or function which performs lexical analysis is called a lexical analyzer, lexer, or scanner.
