Documentation

Overview

Package query implements CSS/jQuery-esque selectors over a PHP AST

Currently, the only supported selectors are:

"node", where node is the type name of an AST node (e.g. EchoStmt)

"parent child", where the descendance may skip levels.

Index

• type Node
• type NodeRule
  • func (r NodeRule) Pass(n Node) bool
• type Q
  • func Select(nodes []ast.Node) Q
  • func (q Q) Select(s string) (Q, error)
• type Rule
• type Selector
  • func ParseSelector(s string) (*Selector, error)
  • func (s Selector) Pass(n Node, local bool) bool

Types

type Node

type Node struct {
	Node   ast.Node
	Parent *Node
}

type NodeRule

type NodeRule struct {
	// Type is the node type represented as a string, without the package name. For example: ReturnStmt.
	Type string
}

func (NodeRule) Pass

func (r NodeRule) Pass(n Node) bool

type Q

type Q []Node

func Select

func Select(nodes []ast.Node) Q

func (Q) Select

func (q Q) Select(s string) (Q, error)

type Rule

type Rule interface {
	Pass(n Node) bool
}

type Selector

type Selector struct {
	// contains filtered or unexported fields
}

func ParseSelector

func ParseSelector(s string) (*Selector, error)

func (Selector) Pass

func (s Selector) Pass(n Node, local bool) bool
