  • package errors

    This package contains various functionality relating to the generation and formatting of error messages.

    This package contains various functionality relating to the generation and formatting of error messages.

    In particular, it includes a collection of combinators for improving error messages within the parser, including labelling and providing additional information. It also contains combinators that can be used to valid data produced by a parser, to ensure it conforms to expected invariances, producing good quality error messages if this is not the case. Finally, this package contains ways of changing the formatting of error messages: this can either be changing how the default String-based errors are formatted, or by injectiing Parsley's errors into a custom error object.

    This package contains various functionality relating to the parsing of expressions..

    This package contains various functionality relating to the parsing of expressions..

    This includes the "chain" combinators, which tackle the left-recursion problem and allow for the parsing and combining of operators with values. It also includes functionality for constructing larger precedence tables, which may even vary the type of each layer in the table, allowing for strongly-typed expression parsing.

    This package contains various functionality that involve Scala's implicits mechanism.

    This package contains various functionality that involve Scala's implicits mechanism.

    This includes conversions from scala literals into parsers, as well as enabling new syntax on regular Scala values (such as Parsley's lift or zipped syntax). Automatic conversion to Parsley[Unit] is also supported within this package.

  • package token

    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.

  2. implicit class DebugCombinators[P, A] extends AnyRef

    This class enables the debug combinator on parsers.

    This class enables the debug combinator on parsers.

    This extension class operates on values that are convertible to parsers. It enables the use of the debug combinator, which can be used to trace the execution through a parser.

    P

    the type of base value that this class is used on (the conversion to Parsley) is summoned automatically.

Debug Combinator Extension Methods

These are the debugging combinators, which are enabled by bringing these implicit classes into scope.

Debug Control

These methods can control how the debug mechanism functions in a general way.

Breakpoints

These can be used to control how the debug combinator operates: when a breakpoint is used it can halt the execution of the combinator and print out information about the parsers state.
