    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.

Abstract Value Members

  1. implicit abstract def implicitSymbol(s: String): Parsley[Unit]

    This method takes the given string and turns it into a parser for that token.

    This method takes the given string and turns it into a parser for that token.

    This method can be brought into scope in a parser to allow string literals to naturally serve as tokens. In particular, it will correctly deal with known keywords and operators, and otherwise handle other strings at face-value.

    4.0.0

    Note

    it is assumed that the token's content is irrelevant, since it is already known what it is, so Unit is returned.
