Hello everyone,
I am trying to use golang.org/x/tools/go/ssa to get the methods list of
each struct type when doing static analysis on Kubernetes.
This is the code I wrote to print out the method sets for each struct or
interface type.
cfg := packages.Config{Mode: packages.LoadAllSyntax}
initial, err := packages.Load(&cfg, pattern)
if err != nil {
log.Fatal(err)
}
prog, _ := ssautil.AllPackages(initial, 0)
prog.Build()
for _, pkg := range prog.AllPackages() {
if pkg.Pkg.Path() == pattern {
for _, member := range pkg.Members {
fmt.Println(member)
if m, ok := member.(*ssa.Type); ok {
fmt.Println(prog.MethodSets.MethodSet(m.Type()))
}
}
}
}
I checked everything printed by fmt.Println(member) but it only contains
the pkg-level functions instead of struct methods.
I also checked everything printed by fmt.Println(prog.MethodSets.MethodSet(m
.Type())) and the method set for each struct/interface only contains the
abstract methods and their implementations. Many other methods (which are
not the implementation of some abstract methods) are missing here.
*In one word, I am able to get all the pkg-level functions in the program
but I am NOT able the get the complete method list of any struct type in
the program.*
*Here is what I want:*
I want to get the complete method list (a list of *ssa.Function pointing to
the method) by calling some API with the struct type (or name)
I googled around and read the related documents here:
https://pkg.go.dev/golang.org/x/tools/go/ssa?tab=doc but didn't find any
clue to solve the problem.
I also read the golang.org/x/tools/go/ssa code but failed to find any API
to do so.
Could anyone help to let me know how to do solve it in
golang.org/x/tools/go/ssa?
Thank you so much!
