On Windows, the program name seems to always be the absolute path to the executable like so:
Perhaps this is intentional, but it makes the help message unnecessarily long. Could the program name be just the filename of the command rather than the path? Or perhaps could it be manually overridden? Perhaps like this:
app := cli.New("myapp", "here is the description...")
Support required options.
This issue is a feature request
Both Arg
and Option
don't support default value now. In order to do that, I can write something like below:
installCommand := cli.NewCommand("install", "Install a package").
WithOption(
cli.NewOption("retry", "maximal retry times (default: 3)").WithType(cli.TypeInt),
).
WithArg(
cli.NewArg("package", "package name").WithType(cli.TypeString),
).
WithAction(func(args []string, options map[string]string) int {
if _, ok := options["retry"]; !ok {
options["retry"] = "3"
}
// do something
})
With WithDefault
method, I can write the default value 3
for only one time and avert a conflict between the actual code and the doc.
