Unexpected Argument Problem

[nobozo]

(go version go1.24.0 linux/amd64, Fedora 41)

Consider the following trivial cutdown example program:

package main

import (
	"fmt"
	"os"

	"github.com/fred1268/go-clap/clap"
)

type TestParams struct {
	Binary string `clap:"-b,--binary,help='Binary path'"`
}

func main() {
	var results *clap.Results
	var err error
	_ = results

	testParams := TestParams{}
	results, err = clap.Parse(os.Args[2:], &testParams)
	if err != nil {
		fmt.Println("Error parsing test command:", err)
		os.Exit(1)
	}
	fmt.Printf("Test parameters: %+v\n", testParams)
}

---

Running this produces the following:

% go run t.go test -b mybinary Error parsing test command: field 'Binary': invalid tag (got '-b,--binary,help='Binary path'', expected a single char value)

This is such a trivial program, and error, that I suspect something bizarre is happening.

What am I doing wrong?

Thanks, Jon

I might have figured this out. I got this program from Google AI, and I think there's a bug. The line that says

Binary string clap:"-b,--binary,help='Binary path'"

should be

Binary string clap:"--binary,-b,help='Binary path'"

since the documentation says:

"A clap struct tag has the following structure:

Name        Type    `clap:"longName[,shortName][,mandatory]"`"

It's too late for me to try this tonight.

I've discovered other issues. The sample program always shows the output (e.g.

{false false} { false}

no matter what I enter.

I'd love to use your package but I'm wondering what its current status is.
