    This package provides a wealth of functionality for performing common lexing tasks.

    This package provides a wealth of functionality for performing common lexing tasks.

    It is organised as follows:

    • the main parsing functionality is accessed via Lexer, which provides implementations for the combinators found in the sub-packages given a LexicalDesc.
    • the descriptions sub-package is how a lexical structure can be described, providing the configuration that alters the behaviour of the parsers produced by the Lexer.
    • the other sub-packages contain the high-level interfaces that the Lexer exposes, which can be used to pass whitespace-aware and non-whitespace-aware combinators around in a uniform way.
    • the predicate module contains functionality to help define boolean predicates on characters or unicode codepoints.

Type Members

  1. final case class Supported(compulsory: Boolean, chars: Set[Char], base: Int, positiveSign: PlusSignPresence) extends ExponentDesc with Product with Serializable

    Exponents are supported, which may be compulsory.

    Exponents are supported, which may be compulsory. The base of the exponent can vary, as can whether a positive (+) sign is allowed before the exponent.

    compulsory

    is an exponent required for the literal (at a specific base) to be valid?

    chars

    the set of possible characters that can start an exponent part of a literal.

    base

    the base of the exponent: for instance e3 with base = 10 would represent multiplication by 1000.

    positiveSign

    are positive (+) signs allowed, required, or illegal in front of the exponent?
