ZIO Parser

Library for constructing parsers and pretty printers based on invertible syntax descriptions

Introduction

Installation

Start by adding zio-parser as a dependency to your project:

libraryDependencies += "dev.zio" %% "zio-parser" % "0.1.9"

Getting Started

import zio.parser.*

Declare your parsing syntax:

val digitSyntax: Syntax[String, Char, Char, Char] = Syntax.digit

Parse your string:

val result: Either[StringParserError[String], Char] = digitSyntax.parseString("1")
// result: Either[StringParserError[String], Char] = Right(value = '1')

Pretty print the parsing errors:

println(digitSyntax.parseString("Hello").left.map(_.pretty).merge)
// Hello
// ^
// error: Failure at position 0: not a digit
//
