Flags in commands

[marksteve]

app.Commands = []cli.Command{
  {
    Name: "command",
    Action: func(c *cli.Context) {
      println("command")
    },
  },
}

I expected appending --help with only show usage but:

$ ./app command --help
Usage of command:
command

[marksteve]

Oops. It was the flag library that was doing it. Not cli's fault.

Oh. I've been up for too long. It is an issue. Flags aren't working properly with commands:

package main

import (
    "os"

    "github.com/codegangsta/cli"
)

func main() {
    app := cli.NewApp()
    app.Name = "app"
    app.Commands = []cli.Command{
        {
            Name: "command",
            Action: func(c *cli.Context) {
                println("command")
            },
            Flags: []cli.Flag{
                cli.BoolFlag{"flag,f", "just a flag"},
            },
        },
    }
    app.Run(os.Args)
}

Running this produces:

$ ./app command --flag
flag provided but not defined: -flag
Usage of command:
  -flag,f=false: just a flag
command

hm. this does seem like a bug. I will look into it soon

@marksteve I am not able to reproduce this on latest master of cli. By the look of that output it looks like you are running an older version that doesn't support the "flag,f" support

Did a go get -u and yeah it works now. Sorry about that. I was sure that it was my first time go get-ting the library but apparently I did before. Thanks for checking it out 😄

[codegangsta]

No problem!
