Functions

func NameOf

func NameOf(node Node) string

NameOf returns name of an ast node.

Types

type Node

type Node interface {
	ast.Node
	ForEach(filter func(node Node) error) error
	Obj() interface{}
}

Node - node interface

type NodeEnum

type NodeEnum interface {
	ForEach(filter func(node Node) error) error
}

NodeEnum - node enumerator

type NodeSet

type NodeSet struct {
	Data NodeEnum
	Err  error
}

NodeSet - node set

func NewSource

func NewSource(
	fset *token.FileSet, path string,
	filter func(os.FileInfo) bool, mode parser.Mode) (doc NodeSet, err error)

NewSource calls ParseFile for all files with names ending in ".gop" in the directory specified by path and returns a map of package name -> package AST with all the packages found.

If filter != nil, only the files with os.FileInfo entries passing through the filter (and ending in ".gop") are considered. The mode bits are passed to ParseFile unchanged. Position information is recorded in fset, which must not be nil.

If the directory couldn't be read, a nil map and the respective error are returned. If a parse error occurred, a non-nil but incomplete map and the first error encountered are returned.

func NewSourceFrom

func NewSourceFrom(
	fset *token.FileSet, fs parser.FileSystem, path string,
	filter func(os.FileInfo) bool, mode parser.Mode) (doc NodeSet, err error)

NewSourceFrom calls ParseFile for all files with names ending in ".gop" in the directory specified by path and returns a map of package name -> package AST with all the packages found.

If filter != nil, only the files with os.FileInfo entries passing through the filter (and ending in ".gop") are considered. The mode bits are passed to ParseFile unchanged. Position information is recorded in fset, which must not be nil.

If the directory couldn't be read, a nil map and the respective error are returned. If a parse error occurred, a non-nil but incomplete map and the first error encountered are returned.

func Nodes

func Nodes(nodes ...Node) NodeSet

Nodes creates a fixed node set.

func One

func One(node Node) NodeSet

One creates a node set that only contains a signle node.

func (NodeSet) Any

func (p NodeSet) Any() (ret NodeSet)

Any returns deeply visiting node set.

func (NodeSet) Cache

func (p NodeSet) Cache() NodeSet

Cache caches node set.

func (NodeSet) Child

func (p NodeSet) Child() NodeSet

Child returns child node set.

func (NodeSet) Collect

Collect collects all nodes of the node set.

func (NodeSet) CollectOne

func (p NodeSet) CollectOne(exactly ...bool) (item Node, err error)

CollectOne collects one node of a node set. If exactly is true, it returns ErrTooManyNodes when node set is more than one.
