Hi there,
I am trying out the new v3 APIs and have run across a rough edge when following the documentation
URLs
The documentation says we can just use
cli.StringFlag{
Sources: cli.ValueSourceChain{
Chain: {
EnvVars("APP_LANG"),
Files("/path/to/foo"),
altsrc.JSON("foo", "/path/to/"),
}
},
}but doing that we get errors like
cannot use (altsrc.JSON("foo", "/path/to/")) (value of type cli.ValueSourceChain) as cli.ValueSource value in argument to cli.NewValueSourceChain: cli.ValueSourceChain does not implement cli.ValueSource (method GoString has pointer receiver)
Example Program
package main
import (
"context"
altsrc "github.com/urfave/cli-altsrc/v3"
"github.com/urfave/cli/v3"
"log/slog"
"os"
)
func main() {
app := cli.Command{
Flags: []cli.Flag{
&cli.StringFlag{
Name: "test",
Sources: cli.NewValueSourceChain(
cli.EnvVar("TEST"),
altsrc.JSON("test", "./config.json"),
),
},
},
}
if err := app.Run(context.Background(), os.Args); err != nil {
slog.Error("Error running app", "err", err)
}
}require (
github.com/urfave/cli-altsrc/v3 v3.0.0-alpha2
github.com/urfave/cli/v3 v3.0.0-beta1
)
