I run this in go version 1.23.4

Hey @Tom5521 , I'm not able to reproduce your issue, could you share detailed steps or resource files you're using (translation files) to identify the bug?

Thanks!

I reproduce it as follows:

On Ubuntu 24.04, with go version 1.22 installed.
In an empty directory, create hello3.go with this contents:

package main

import (
	"fmt"
	"github.com/leonelquinteros/gotext"
)

func main () {
	// Specify localedir, locale, domain.
	gotext.Configure ("./locale", "fr_FR", "hello")

	fmt.Println (gotext.Get ("Hello world!"))
	fmt.Println (gotext.Get ("Hello %s", "Dolly"))
}

and go.mod with this contents:

module hello
go 1.11
require github.com/leonelquinteros/gotext v1.7.0

Then

chmod -R u+w ~/go/; rm -rf ~/go/
go get github.com/leonelquinteros/gotext
go run hello3.go
go get github.com/leonelquinteros/gotext/cli/xgotext
go install github.com/leonelquinteros/gotext/cli/xgotext
mkdir -p po
PATH=${GOPATH-$HOME/go}/bin:$PATH xgotext -default hello -in . -out po

Result:

panic: runtime error: invalid memory address or nil pointer dereference [recovered]
        panic: runtime error: invalid memory address or nil pointer dereference
