Functions ¶

func IsStd ¶

func IsStd(p *packages.Package) bool

IsStd returns whether *packages.Package is a std package

func IsStdName(id string) bool

IsStdName returns whether id corresponds to a standard package

func IsTestPkg ¶ added in v0.5.0

func IsTestPkg(pkg *packages.Package) bool

func LoadStd ¶ added in v0.5.3

func LoadStd()

LoadStd preloads the std package list.

func Parse ¶

func (Context) Config ¶

func (ctx Context) Config() *packages.Config

func (Context) Load ¶

func (ctx Context) Load(patterns ...string) ([]*packages.Package, error)

func (Context) LoadWithTests ¶ added in v0.4.2

func (ctx Context) LoadWithTests(patterns ...string) ([]*packages.Package, error)

func (Context) LoadWithoutTests ¶ added in v0.4.2

type Set ¶

type Set map[string]*packages.Package

Set is a p.ID -> *packages.Package

func Calc ¶

func Calc(parentContext context.Context, expr []string) (Set, error)

Calc parses expr and computes the set of packages it describes.

func Deadcode ¶ added in v0.9.0

func Deadcode(ctx *Context, pkgs Set) (Set, error)

Deadcode returns packages from the set that directly or indirectly call a function annotated with <ReflectMethod> in the linker dependency graph. This is typically caused by reflect.Value.MethodByName or similar calls, which force the linker to keep all interface methods alive.

func DirectDependencies ¶

func DirectDependencies(a Set) Set

DirectDependencies returns packages that are direct dependencies of a, `a` not included.

func Incoming ¶

func Incoming(a, b Set) Set

Incoming returns packages from a that directly import packages in b.

Intersect returns packages that exist in both

func Main ¶

func Main(a Set) Set

Main returns main pacakges.

func ModuleDependencies ¶ added in v0.6.0

func ModuleDependencies(a Set) Set

ModuleDependencies returns packages that are direct or indirect dependencies of a, which are part of modules of package a.

func NewAll(src Set) Set

NewAll includes all the dependencies from the graph.

func NewRoot ¶

func NewRoot(roots ...*packages.Package) Set

NewRoot makes a set from roots recursively

func Reach ¶

func Reach(a, b Set) Set

Reach returns packages in a that terminate in b

func Sources ¶

func Sources(a Set) Set

Sources returns packages that don't have incoming edges, only considering edges between packages in the set.

func Std ¶

func Std() Set

Std returns the standard package set

func Subtract ¶

func Subtract(a, b Set) Set

Subtract returns packages that exist in a, but not in b

func SymmetricDifference ¶

func SymmetricDifference(a, b Set) Set

SymmetricDifference returns packages that are different

func Test ¶ added in v0.4.2

func Test(a Set) Set

IncludeRecursive adds p recursively

func (Set) List ¶

func (set Set) List() []*packages.Package

List returns packages in unsorted order.

func (Set) Sorted ¶

func (set Set) Sorted() []*packages.Package

Sorted returns packages in sorted order
