trait Lexer extends AnyRef

A trait for a lexer that allows separating a string into "tokens" and "delimiters". Each lexer defines tokens and delimiters differently. A whitespace lexer assigns whitespace runs as delimiters and non-whitespace runs as tokens. A capitalization-based lexer creates tokens when capitalization changes from lower case to upper case but produces no delimiters.

Abstract Value Members

  1. abstract def lex(s: String): LexResult

    Lazily separate a string into tokens based on some boundary condition and preserve the delimiter characters that were between the boundaries, including any leading or trailing delimiters.

    Lazily separate a string into tokens based on some boundary condition and preserve the delimiter characters that were between the boundaries, including any leading or trailing delimiters.

    s

    string to separate

    returns

    a lazy result

  2. abstract def tokens(s: String): Iterator[String]

    Separate a string into tokens based on some boundary condition ignoring any delimiter characters between any two tokens.

    Separate a string into tokens based on some boundary condition ignoring any delimiter characters between any two tokens.

    s

    string to separate into tokens

    returns

    Iterator of tokens
