    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 class String extends AnyRef

This class defines a uniform interface for defining parsers for string literals, independent of whether the string is raw, multi-line, or should consume whitespace after the literal.

Note

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

Abstract Value Members

  1. abstract def ascii: Parsley[scala.Predef.String]

    This parser will parse a single string literal, which may contain any number of graphic ascii characters.

    This parser will parse a single string literal, which may contain any number of graphic ascii characters. It may contain escape sequences, and potentially support string gaps and zero-width characters depending on the configuration.

    Example: 

    1. scala> ascii.parse("\"μαϊντανός!\"")
val res0 = Failure(...) // Greek is not part of ascii
scala> ascii.parse("\"hello world\"")
val res1 = Success("hello world")
scala> ascii.parse("\"🙂\"")
val res2 = Failure(...) // Emoji are not part of ascii
scala> ascii.parse("\"£10\"")
val res3 = Failure(...) // £ is not part of ascii

    Note

    the exact behaviour of this parser is decided by the implementations given in Lexer, which will depend on user-defined configuration. Please see the relevant documentation of these specific objects.

  2. abstract def fullUtf16: Parsley[scala.Predef.String]

    This parser will parse a single string literal, which may contain any number of graphical UTF-16 unicode characters; including those that span multiple 32-bit codepoints.

  3. abstract def latin1: Parsley[scala.Predef.String]

    This parser will parse a single string literal, which may contain any number of graphic extended ascii characters (known as latin1).
