    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. abstract class Combined extends AnyRef

    This class defines a uniform interface for defining parsers for mixed kind numeric literals, independent of how whitespace should be handled after the literal or whether the literal should allow for negative numbers.

    Note

    implementations of this class found within Lexer may employ sharing and refine the non-final defs in this class into val or lazy val when overriding.

  2. abstract class Integer extends AnyRef

    This class defines a uniform interface for defining parsers for integer literals, independent of how whitespace should be handled after the literal or whether the literal should allow for negative numbers.

  3. sealed class LowPriorityImplicits extends AnyRef

    This class is used to provide "low-priority" implicits for the types defined within CanHold.

    This class is used to provide "low-priority" implicits for the types defined within CanHold.

    These implicits are not favoured equally to the implicits defined within CanHold and this means that Scala will not have any ambiguous implicit errors.

  4. abstract class Real extends AnyRef

    This class defines a uniform interface for defining parsers for floating literals, independent of how whitespace should be handled after the literal.

Value Members

  1. object CanHold extends LowPriorityImplicits

    This object contains the definitions of several types that help enforce that parsers of bounded precision only return types that can losslessly accomodate that precision.

    This object contains the definitions of several types that help enforce that parsers of bounded precision only return types that can losslessly accomodate that precision.

    Note that, on the JVM, there is no such thing as an unsigned value natively. Instead, the JVM provides a guarantee that overflow is well-defined, and, as such supports operations that work on numbers as if they were unsigned. For this reason, parsley makes no distinction between unsigned and signed numbers.
