Advanced Usage

Passing Custom Arguments

Clerc allows you to pass a custom array of arguments instead of using the default process.argv / Deno.args. This is useful for testing or specific environments.

Cli().parse(["node", "my-cli", "greet"]); // Pass a custom array of arguments

Alternatively, you can also pass an argument object:

Cli().parse({
  argv: ["greet"],
});

Parse Only Without Execution

Sometimes you may want to parse commands and flags without immediately executing the command handler. Clerc provides an option to achieve this:

const result = Cli().parse({
  run: false, // Parse only, do not execute
});

When you need to run, you can call:

result.run(); // Execute the parsed command
