Example usage:

# Count characters, like `wc`
echo 'fourteen chars' | pkl eval package://pkg.pkl-lang.org/pkl-pantry/pkl.pipe@<VERSION>#/text.pkl -x 'pipe.length'

# Get Pkl filenames as a JSON array (multiple options for JSON-encoding)
ls | pkl eval package://pkg.pkl-lang.org/pkl-pantry/pkl.pipe@<VERSION>#/text.pkl -x 'pipe.split("\n").filter((n) -> n.endsWith("pkl")) |> asJSON'
ls | pkl eval package://pkg.pkl-lang.org/pkl-pantry/pkl.pipe@<VERSION>#/text.pkl -x 'asJson(pipe.split("\n").filter((n) -> n.endsWith("pkl")))'
ls | pkl eval package://pkg.pkl-lang.org/pkl-pantry/pkl.pipe@<VERSION>#/text.pkl -x 'pipe.split("\n").filter((n) -> n.endsWith("pkl")) |> formatted' -f json

# Get all filenames grouped by extension
ls | pkl eval package://pkg.pkl-lang.org/pkl-pantry/pkl.pipe@<VERSION>#/text.pkl -x 'asYaml(pipe.split("\n").groupBy((element) -> element.split(".").last))'

# Years since the Unix epoch

Methods(show inherited)

link

function

getClass(): Class (pkl.base)Source

Returns the class of this.
link

function

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

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.
link

function

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

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

function

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

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

Returns the value of the property with the given name.

Returns null if a property with this name does not exist.
link

function

toDynamic(): Dynamic (pkl.base)Source

Converts this object to a Dynamic object.
link

function

toMap(): Map<String, unknown> (pkl.base)Source

Converts this object to a Map.
link

function
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)
```
