Functions ¶
func Convert ¶
Convert converts specified type to a type which contains only basic types. e.g. (MyInt is defined by "type MyInt int")
[]MyInt -> []int <-chan MyInt -> <-chan int map[MyInt]MyInt -> map[int]int
if ptrElem is true, Convert converts a pointer type to its elem type. e.g. *string -> string
Example ¶
package main
import (
"fmt"
"go/ast"
"go/importer"
"go/parser"
"go/token"
"go/types"
"github.com/tenntenn/underlying"
)
func main() {
const src = `package main
type MyInt int
type Example struct {
N MyInt
S *string
}
func main() {}`
fset := token.NewFileSet()
f, err := parser.ParseFile(fset, "main.go", src, 0)
if err != nil {
panic(err)
}
info := &types.Info{
Defs: map[*ast.Ident]types.Object{},
}
config := &types.Config{
Importer: importer.Default(),
}
pkg, err := config.Check("main", fset, []*ast.File{f}, info)
if err != nil {
panic(err)
}
typ := pkg.Scope().Lookup("Example").Type()
fmt.Println(underlying.Convert(typ, true))
}
Output: struct{N int; S string}
Types ¶
type Converter ¶
type Converter struct {
PtrElem bool
}
Converter converts specified type to a type which contains only basic types.
func (*Converter) Convert ¶
Convert converts specified type to a type which contains only basic types. e.g. (MyInt is defined by "type MyInt int")
[]MyInt -> []int <-chan MyInt -> <-chan int map[MyInt]MyInt -> map[int]int
if ptrElem is true, Convert converts a pointer type to its elem type. e.g. *string -> string
