Hello,

I am trying to transpile junegunn/fzf, a really really good fuzzy-finder written in Golang.

My main-Function looks like this:

package main

import (
	"github.com/gopherjs/gopherjs/js"
	"github.com/junegunn/fzf/src/algo"
	"github.com/junegunn/fzf/src/util"
)

func main() {
	js.Global.Set("fzf", map[string]interface{}{
		"FuzzyMatchV2": algo.FuzzyMatchV2,
	})
}

Calling fzf.FuzzyMatchV2(true, false, false, "Hello World", "aW", true, null) leads to an error:

..js:1419 Uncaught Error: runtime error: cannot internalize util.Chars

The util.Chars-Struct looks like this:

type Chars struct {
	slice           []byte // or []rune
	inBytes         bool
	trimLengthKnown bool
	trimLength      uint16

	// XXX Piggybacking item index here is a horrible idea. But I'm trying to
	// minimize the memory footprint by not wasting padded spaces.
	Index int32
}

If you want to try it, use my fork of fzf, branch "gopherjs". There is a small change, which takes out some unix syscall dependencies, to make the build happen.

I cannot find out what is leading to this error. Any help is appreciated.

Thanks in advance.
