Ah, good question. By default, slice arguments consume all command line strings from the point that the user wrote -s
to the end of the command line. So in your last example, you will find that Snippets contains two strings: "InsecureRootPw" and "SYSTEM_42123".
One way you can change this default behavior is by putting the tag separate
into the Snippets field:
type systemDeployCmd {
...
Snippets []string `arg:"-s,separate"`
...
}
Then the user will have to put a -s
for each snippet on the command line:
./forester-cli system deploy -s Snippet1 -s Snippet2 -s Snippet3
And in this way you can put the positional argument at the end as in your example and it will work as you expect.
