Init input source from toml, but got empty field

[asaarashi]

I have

package main

import (
    "os"
    "gopkg.in/urfave/cli.v1"
    "github.com/urfave/cli/altsrc"
    "log"
)

func main() {
    app := cli.NewApp()
    app.Name = "pusher"
    app.Description = "tbuploather pusher"

    flags := []cli.Flag{
        cli.BoolFlag{Name: "debug, d", Usage: "debug"},
        altsrc.NewStringFlag(cli.StringFlag{Name: "dsn, D", Usage: "MySQL DSN"}),
        altsrc.NewStringSliceFlag(cli.StringSliceFlag{Name: "broker-list, b", Usage: "Kafka brokers"}),
        cli.StringFlag{Name: "log-path, l", Value: "/var/log/tbuploather/pusher.log", Usage: "File log path"},
        cli.StringFlag{Name: "config-file, c", Value: "pusher.toml", Usage: "Config file path"},
    }
    app.Action = DefaultAction
    app.Before = altsrc.InitInputSourceWithContext(flags, altsrc.NewTomlSourceFromFlagFunc("config-file"))
    app.Flags = flags

    err := app.Run(os.Args)
    if err != nil {
        log.Println(err)
    }
}

but

ctx.String("dsn")

is always empty.

This is my toml file

debug = false
broker-list = ["192.168.30.169:9092,33333"]
log-path = "/var/log/tbuploather/pusher.log"
dsn = "root:asdf@tcp(192.168.30.169:3306)/tbuploather"

what's the possible reason? Thx!

I would try switching to urfave/cli.v2 and also removing the aliases for your cli arguments: e.g. dsn, D => dsn to start

Hiya! There's a known issue with the current implementation of the CLI, where altsrc is generally clunky and poorly documented. My current idea is that I'm going to move all of the altsrc functionality into the main package in some way, and that's how all of the "altsrc is weird and different???" issues people are having will get resolved. I'm tracking that work here => #833

Does altsrc work then? Having the same issues

[prestonvanloon]

This doesn't work with v2 either.

Many things with altsrc are known broken in v2
