Module.output: ModuleOutput (pkl.base)Source

The output of this module.

Defaults to all module properties rendered as either Pcf or the format specified on the command line.

Schema.type: ("string"|"number"|"integer"|"boolean"|"object"|"array")? (org.openapis.v3.Schema)Source

The basic type of the value represented by this schema.

If this property is not defined, the value may be of any type.

link

An additional descriptor for the value represented by this schema.

OAS uses several known formats to define in fine detail the data type being used.

However, to support documentation needs, the format property is an open string-valued property, and can have any value. Formats such as "email", "uuid", and so on, may be used even though undefined by this specification. Types that are not accompanied by a format property follow the type definition in the JSON Schema. Tools that do not recognize a specific format may default to the type alone, as if the format is not specified.

The formats defined by the OAS are:

Common Name	`type`	`format`	Comments
integer	`integer`	`int32`	signed 32 bits
long	`integer`	`int64`	signed 64 bits
float	`number`	`float`
double	`number`	`double`
string	`string`
byte	`string`	`byte`	base64 encoded characters
binary	`string`	`binary`	any sequence of octets
boolean	`boolean`
date	`string`	`date`	As defined by `full-date` - RFC3339
dateTime	`string`	`date-time`	As defined by `date-time` - RFC3339
password	`string`	`password`	A hint to UIs to obscure input.

link

Schema.description: String? (org.openapis.v3.Schema)Source

A long descriptor of this schema. Maybe written in Markdown.

Schema.default: Any? (org.openapis.v3.Schema)Source

Specifies a default value.

This value is not used to fill in missing values during the validation process. Non-validation tools such as documentation generators or form generators may use this value to give hints to users about how to use a value. However, default is typically used to express that if a value is missing, then the value is semantically the same as if the value was present with the default value. The value of default should validate against the schema in which it resides, but that isn't required.

Schema.enum: Listing<Any>(!isEmpty && isDistinct)? (org.openapis.v3.Schema)Source

Schema.discriminator: Discriminator? (org.openapis.v3.Schema)Source

Helps inform of alternative schemas.

When request bodies or response payloads may be one of a number of different schemas, a discriminator object can be used to aid in serialization, deserialization, and validation. The discriminator is a specific object in a schema which is used to inform the consumer of the specification of an alternative schema based on the value associated with it.

When using the discriminator, inline schemas will not be considered.

link

Schema.readOnly: Boolean? (org.openapis.v3.Schema)Source

Declares the property as "read only".

Relevant only for Schema properties definitions. This means that it may be sent as part of a response but should not be sent as part of the request. If the property is marked as readOnly and is in the required list, required only effects the response. A property may not be marked as both readOnly and writeOnly.

Default value is false.

https://github.com/OAI/OpenAPI-Specification/blob/main/versions/3.0.3.md#fixed-fields-20
link

Schema.writeOnly: Boolean(implies(readOnly != true))? (org.openapis.v3.Schema)Source

Declares the property as "write only".

This is relevant only for Schema properties definitions. Therefore, it it may be sent as part of a response but should not be sent as part If the property is marked as writeOnly being true and is in the required list, the required will take effect on the request only. A property may not be marked as both readOnly and writeOnly being true.

Default value is false.

Schema.example: Any? (org.openapis.v3.Schema)Source

To represent examples that cannot be naturally represented in JSON or YAML, a string value can be used to contain the example with escaping where necessary.
link

hidden

Schema.extensions: Mapping<Key, Any>? (org.openapis.v3.Schema)Source

Custom properties starting with x- extend OpenAPI with additional information or functionality.

This is a child property because Pkl modules cannot express both known names and arbitrary names.

link

xml: Xml?Source

Adds additional metadata to describe the XML representation of this property.

This may be used only on properties schemas. It has no effect on root schemas.

Methods(show inherited)

link

function

Any.getClass(): Class (pkl.base)Source

Returns the class of this.
link

function

Any.toString(): String (pkl.base)Source

Returns a string representation of this.

This method is used to convert the values of string interpolation expressions to strings.
link

function

Any.ifNonNull<Result>(transform: (NonNull) -> Result): Result? (pkl.base)Source

Returns this |> transform if this is non-null, and null otherwise.

This method is the complement of the ?? operator and the equivalent of an Option type's map and flatMap methods.

Typed.hasProperty(name: String): Boolean (pkl.base)Source

Tells if this object has a property with the given name.
link

function

Typed.getProperty(name: String): unknown (pkl.base)Source

Returns the value of the property with the given name.

Throws if a property with this name does not exist.
link

function

Typed.getPropertyOrNull(name: String): unknown? (pkl.base)Source

link

function

Typed.toDynamic(): Dynamic (pkl.base)Source

link

function
Module.relativePathTo(other: Module): List<String> (pkl.base)Source

Returns the relative, descendent directory path between this module and other.
Throws if no such path exists.

For example, if module mod1 has path /dir1/mod1.pkl, and module mod2 has path /dir1/dir2/dir3/mod2.pkl, then mod1.relativePathTo(mod2) will return List("dir2", "dir3").

A common use case is to compute the directory path between a template located at the root of a hierarchy (say rootModule.pkl) and the currently evaluated module (accessible via the module keyword):
```
import "rootModule.pkl" // self-import
path = rootModule.relativePathTo(module)
```
