Printing self help about cli HOT 5 CLOSED

Same question when-using/for child-command: https://github.com/mkideal/cli#example-8-child-command

from cli.

You can print help message directly:

if argv.Port < 1024 {
    ctx.String("Print yourself help information\n")
}

from cli.

yeah, but I want to print a self help,
"where the self help is the output of running the program with -h"

not construction it again myself.

from cli.

You can print help message as below:

if argv.Port < 1024 {
    ctx.WriteUsage()
}

from cli.

Oh,

Thought it was https://godoc.org/github.com/mkideal/cli#Context.Usage, but it's actually https://godoc.org/github.com/mkideal/cli#Context.WriteUsage

Thanks

from cli.
