# Number option

Learn how to define numeric options for templates.

Number options accept a numeric value, such as a port, a count, or a limit.

## Example

The following template repeats a greeting a given number of times:

**template.json5**

```json5
{
  "$schema": "https://schema.croct.com/json/v1/template.json",
  "title": "Repeat greeting",
  "description": "Prints a greeting a given number of times.",
  "options": {
    "times": {
      "type": "number",
      "description": "How many times to greet.",
      "default": 1
    }
  },
  "actions": [
    {
      "name": "print",
      "semantics": "info",
      "message": "${'Hello!\\n'.repeat(options.times)}"
    }
  ]
}
```

You can pass the option directly as a flag:

```sh
croct use template.json5 --times 3
```

This prints `Hello!` three times.
