Functions

func CodeOf added in v1.3.2 

func CodeOf(fset *token.FileSet, f *ast.File, start, end token.Pos) string

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() any
}

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 FromDir added in v1.3.2 

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

FromDir 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 fs.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 FromFSDir added in v1.3.2 

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

FromFSDir 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 fs.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 FromFSFile added in v1.3.2
