Package structure
The parsley package contains the
Parsleyclass, as well as theResult,Success, andFailuretypes. In addition to these, it also contains the following packages and "modules" (a module is defined as being an object which mocks a package):parsley.Parsleycontains the bulk of the core "function-style" combinators, as well as the implicit classes which enable the "method-style" combinators.parsley.combinatorcontains many helpful combinators that simplify some common parser patterns.parsley.charactercontains the combinators needed to read characters and strings, as well as combinators to match specific sub-sets of characters.parsley.debugcontains debugging combinators, helpful for identifying faults in parsers.parsley.iocontains extension methods to run parsers with input sourced from IO sources.parsley.exprcontains the following sub modules:parsley.expr.chaincontains combinators used in expression parsingparsley.expr.precedenceis a builder for expression parsers built on a precedence table.parsley.implicitscontains several implicits to add syntactic sugar to the combinators. These are sub-categorised into the following sub modules:parsley.implicits.charactercontains implicits to allow you to use character and string literals as parsers.parsley.implicits.combinatorcontains implicits related to combinators, such as the ability to make any parser into aParsley[Unit]automatically.parsley.implicits.liftenables postfix application of the lift combinator onto a function (or value).parsley.implicits.zippedenables boths a reversed form of lift where the function appears on the right and is applied on a tuple (useful when type inference has failed) as well as a.zippedmethod for building tuples out of several combinators.parsley.errorscontains modules to deal with error messages, their refinement and generation.parsley.errors.combinatorprovides combinators that can be used to either produce more detailed errors as well as refine existing errors.parsley.liftcontains functions which lift functions that work on regular types to those which now combine the results of parsers returning those same types. these are ubiquitous.parsley.registerscontains combinators that interact with the context-sensitive functionality in the form of registers.parsley.tokencontains theLexerclass that provides a host of helpful lexing combinators when provided with the description of a language.parsley.unsafecontains unsafe (and not thread-safe) ways of speeding up the execution of a parser.
