Types ¶
type Dumper ¶
type Dumper struct { Writer io.Writer Indent string Comments parser.Comments Positions parser.Positions 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.Parse() nodes := php7parser.GetRootNode() nsResolver := visitor.NewNamespaceResolver() nodes.Walk(nsResolver) dumper := visitor.Dumper{ Writer: os.Stdout, Indent: "| ", Comments: php7parser.GetComments(), Positions: php7parser.GetPositions(), NsResolver: nsResolver, } nodes.Walk(dumper) }
