Args
Use the args shortcode to generates a table of structured arguments.
Use the args shortcode to generates a table of structured arguments. The argument definitions are expected to be defined in a data file identified by a provided structure name.
| Name | Type | Required | Default | Comment |
|---|---|---|---|---|
| group | string | Name of the group filter. This is typically used when a shortcode and partial have common arguments. The group filter binds a specific argument to a particular group. By default, an argument belongs to all groups. | ||
| parent | bool | Flag to filter only arguments that have a parent attribute (either cascade or merge). |
||
| structure | string | yes | Name of the data file that contains argument definitions. Supported data formats include JSON, TOML, YAML, and XML. You can omit the file extension. The file should reside in the data/structures folder. |

Define a file in the data/structures folder that contains the argument specifications.
The format supports the following attributes:
| Name | Required | Description |
|---|---|---|
| name | yes | Argument name. |
| type | yes | Data type of the argument, either a primitive or complex type. |
| optional | Flag to indicate if the argument is optional, defaults to false. | |
| default | Default value when no value is provided. | |
| parent | Defines if the argument inherits a value from its parent, either cascade or merge. |
|
| release | Points to the version in which the argument was released. See the Release shortcode for more details. | |
| deprecated | Points to the version in which the argument was deprecated. See the Release shortcode for more details. | |
| comment | Documentation about the argument. | |
| options | Conditional value requirements, pending data type. |
Several primitives are supported. The validation function uses these to test if the provided argument value conforms to the expected data type.
| Primitive | Description |
|---|---|
| bool | Boolean, either true or false. The validation supports both quoted and unquoted values. Maps to the Hugo type bool. |
| string | Free format plain text. Maps to the Hugo type string. |
| int | A whole number, including negative values. Optionally, specify the allowed value range using options.min and options.max. Maps to the Hugo type int. |
| float | A fractional number, including negative values. Optionally, specify the allowed value range using options.min and options.max. Maps to the Hugo type float64. |
| select | A single string value from a set of options. Specify the allowed values in options.values. Maps to the Hugo type string. |
| datetime | A date with optional time value. |
| url | A web address to a particular file or page. The address should include the protocol, hostname, and optional file name. Maps to the Hugo type string. |
| path | Path to a local file or directory. By convention, paths that start with / are relative to the repository root. When used as source argument, the base directory may be mapped to one of Hugo’s mount folders (e.g. assets, data, content, static). Windows paths are mapped to Unix-style paths using forward slashes. Maps to the Hugo type string. |
Any provided type not matching a primitive is considered a complex type. Type confirmation is tested with printf "%T". For example, to validate if the page context is of the correct type, use *hugolib.pageState.
