Go Reference

Go Parser Combinator with Go Generics.

Roadmap

  • stream input type
  • complete input type
  • custom input types
  • combinator
  • string parser
  • bytes parser
  • examples
    • JSON parser
    • HTTP parser
    • tiny tree-walked interpreter

How to use

currently this library is so simple. you only should follow 2 steps as below.

  • initializes parser.Parser[I, O]
  • call the parser

Examples

(WIP) JSON Parser
$ go run ./examples/jsonparser/ examples/jsonparser/example.json
{[{[a b] 2} {[c d] 2} {[e f] 2}] 3}
Simplest Case
package main

import (
    "github.com/Drumato/peachcomb/pkg/strparse"
    "github.com/Drumato/peachcomb/pkg/combinator"
)

func main() {
	element := strparse.Digit1()
	separator := strparse.Rune('|')
	p := combinator.Separated1(element, separator)

	i := strparse.NewCompleteInput("123|456|789Drumato")
	_, o, err := p(i)
	fmt.Printf("%d\n", len(o))
	fmt.Printf("%s %s %s\n", o[0], o[1], o[2])
	fmt.Println(err)
}
$ go run main.go
