Parsicle

A Swift parser combinator framework.

Extracted from InterfaCSS, originally inspired by Parcoa.

Getting started

Install

The simplest way is to use CocoaPods.

Support for Swift Package Manager is also on the way...

Examples

Simple example with sequential parser

let parsicle = Parsicles.sequential([
                                     .string("Hello"), 
                                     .spaces(1), 
                                     .string("World"), 
                                     .spaces(1),
                                     .choice([
                                              .char("🤯"),
                                              .char("😍"),
                                              .char("💩"), 
                                             ]), 
                                    ])
                                    
if parsicle.matches("Hello World 🤯") {
  print("🎉")
}

Example using Swift function builder syntax

Sequential {
  "Hello"
  Spaces(1)
  "World"
  Spaces()
  Choice {
    "🤯"
    "😍"
    "💩"
  }
}
