can I remove default text when a flag's value is set

It seems that when I set a flag's value, the help info will show a default text , even if I do not try to set a default text hint.
for example, if I create a IntFlag, then its value is 0 as default, which is initialize by golang itself. then the default text is shown as (default: 0). But I didn't set the value as 0, and the default text was not supposed to show

I have a similar issue I'm not sure how to handle. If I set an env var for a flag, say for a sensitive value like an api token, I don't want the help outputing that token as a "default" value if it's set in the environment at the time. How do I use the EnvVars flags without effecting the default help text?

@Toady00 One thing I found you can do is set DefaultText: "" on the flag.

@valorl's suggestion isn't working for me with a BoolFlag:

--help, -h                       Show help (default: false)

@lorensr Can you check if this problem exists with latest release as well ? We've made some changes to default handling

[lorensr]

@dearchap I'm getting the same behavior on latest v2.23.7

[dearchap]

@lorensr can you post a code snippet ?

[lorensr]

cli.HelpFlag = &cli.BoolFlag{
	Name:    "help",
	Aliases: []string{"h"},
	Usage:   "Show help",
	DefaultText: "",
}

Setting DefaultText: "" does not remove the (default: false) output below:

--help, -h                       Show help (default: false)

Can you set DefaultText to " " or a non empty string?

[lorensr]

Here is " ":

   --help, -h     Show help (default:  )

[dearchap]

Okay I see the issue now. So would you like to hide the default text only for bool flags or for all flags ?

[lorensr]

Only for these two flags:

GLOBAL OPTIONS:
   --help, -h     show help (default: false)
   --version, -v  print the version (default: false)

and not for other bool flags or flags of other types.

@lorensr Can you try the PR and see if it works for you ? Thanks

@dearchap I'm on v2.25.7, and now by default I don't see (default: false). However, if I change show help to Show help with this, (default: false) comes back:

cli.HelpFlag = &cli.BoolFlag{
	Name:    "help",
	Aliases: []string{"h"},
	Usage:   "Show help",
	DefaultText: "",
}
