type Dumper ¶

type Dumper struct {
	Writer     io.Writer
	Indent     string
	NsResolver *NamespaceResolver
}

Dumper writes ast hierarchy to an io.Writer Also prints comments and positions attached to nodes

Example ¶

package main

import (
	"bytes"
	"os"

	"github.com/z7zmey/php-parser/php7"
	"github.com/z7zmey/php-parser/visitor"
)

func main() {
	src := `<?php

		namespace Foo {
			class Bar { 
				public function FunctionName(Type $var = null)
				{
					// some comment
					$var;
				}
			}
		}`

	php7parser := php7.NewParser(bytes.NewBufferString(src), "test.php")
	php7parser.WithFreeFloating()
	php7parser.Parse()
	nodes := php7parser.GetRootNode()

	nsResolver := visitor.NewNamespaceResolver()
	nodes.Walk(nsResolver)

	dumper := &visitor.Dumper{
		Writer:     os.Stdout,
		Indent:     "| ",
		NsResolver: nsResolver,
	}
	nodes.Walk(dumper)

}
