Enable stop early. If enabled, all arguments starting from the first non option argument will be passed as arguments with type string to the command action handler.
For example:
command --debug-level warning server --port 80
Will result in:
- options: { debugLevel: 'warning' }
- args: ['server', '--port', '80']
Handle error. If throwErrors is enabled the error will be thrown,
otherwise a formatted error message will be printed and Deno.exit(1)
will be called. This will also trigger registered error handlers.
Throw validation errors instead of calling Deno.exit() to handle
validation errors manually.
A validation error is thrown when the command is wrongly used by the user. For example: If the user passes some invalid options or arguments to the command.
This has no effect for parent commands. Only for the command on which this method was called and all child commands.
Example:
import { Command, ValidationError } from "./mod.ts";
const cmd = new Command();
// ...
try {
cmd.parse();
} catch(error) {
if (error instanceof ValidationError) {
cmd.showHelp();
Deno.exit(1);
}
throw error;
}
Register custom type.
Set the command usage. Defaults to arguments.
Disable parsing arguments. If enabled the raw arguments will be passed to the action handler. This has no effect for parent or child commands. Only for the command on which this method was called.
