Go 1.18 Type Parameters Support

[buddy-sandidge]

Running pkger 1.17.1 will error when running on Go 1.18 code that uses type parameters/generics. An example can be found in this gist.

$ pkger
2022/03/30 13:10:19 /tmp/pkger-test/main.go:10:13: expected '(', found '[' (and 5 more errors): ParseDir failed /tmp/pkger-test: /tmp/pkger-test

An example of Go code that will cause the error.

package main

import (
	"io"
	"os"

	"github.com/markbates/pkger"
)

func Example[T any]() {}

func main() {
	f, err := pkger.Open("/file.txt")
	if err != nil {
		panic(err)
	}
	defer func() { _ = f.Close() }()

	if _, err := io.Copy(os.Stdout, f); err != nil {
		panic(err)
	}
}
