Types

type PackageInfo

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

PackageInfo represents information of packages used by a applicaion for gottani. It also implements types.Importer for parsing and type-checking.

func New

func New(dir string) (*PackageInfo, error)

New creates PackageInfo with default setting and then Load the given dir

func NewPackageInfo

func NewPackageInfo(fset *token.FileSet, tinfo *types.Info) *PackageInfo

NewPackageInfo creates PackageInfo

func (*PackageInfo) AllPackages

func (ip *PackageInfo) AllPackages() []*build.Package

Packages returns a slice of *build.Packages that are depended by the loaded package.

func (*PackageInfo) FileSet

func (ip *PackageInfo) FileSet() *token.FileSet

FileSet() returns the *token.FileSet that holds all source code for whole the application except standard packages.

func (*PackageInfo) GetAstFiles

func (ip *PackageInfo) GetAstFiles(bp *build.Package) []*ast.File

GetTypesPackage() returns the slice of *ast.File for the package specified by the given bp. It includs Go files and Cgo files.

func (*PackageInfo) GetBuildPackage

func (ip *PackageInfo) GetBuildPackage(importPath, dir string) *build.Package

GetBuildPackage() returns the *build.Package coresponds for the given importPath on the given dir.

func (*PackageInfo) GetTypesPackage

func (ip *PackageInfo) GetTypesPackage(bp *build.Package) *types.Package

GetTypesPackage() returns the *type.Package for the package specified by the given bp.

func (*PackageInfo) Import

func (ip *PackageInfo) Import(path string) (*types.Package, error)

Import imports package specified by the path and returns its type information

func (*PackageInfo) ImportFrom

func (ip *PackageInfo) ImportFrom(path, dir string, mode types.ImportMode) (*types.Package, error)

Import imports package specified by the given path and dir, then returns its type information The mode must be set 0. It is reserved for future use.

func (*PackageInfo) Load

func (ip *PackageInfo) Load(dir string) error

Load loads package information of the application given by the dir

func (*PackageInfo) Packages

func (ip *PackageInfo) Packages() []*build.Package

Packages returns a slice of *build.Packages that are depended by the loaded package and non standard ones.

func (*PackageInfo) Root

func (ip *PackageInfo) Root() *build.Package

Root() returns the package that is in the directory given on Load().

func (*PackageInfo) TypesInfo

func (ip *PackageInfo) TypesInfo() *types.Info

TypesInfo() returns the *types.Info that holds all type information for whole the application.

func (*PackageInfo) WalkPackages

func (ip *PackageInfo) WalkPackages(prune func(*build.Package) bool, pre Walker, post Walker)

WalkPackages travarse packages and do the given pre and/or post function for each package

type Walker

type Walker func(bp *build.Package, tp *types.Package, asts []*ast.File)

Walker is alias to a function type for PackageInfo.WalkPacakge().
