|
Reads one value from the merged `cli_input(context)` parameter tree.
|
|
|
|
If the key is missing, or the resolved value is empty, `default_value` is returned.
|
|
|
|
|
|
For commands that need multiple values or typed reads, prefer calling `cli_input(context)` once and reading the returned `DValue` directly.
|
|
|
|
:example
|
|
String name = cli_arg(context, "name", "world");
|
|
print("hello ", name, "\n");
