Wren is a lightweight, object-oriented programming language designed to be an easily-embeddable scripting language.

It is under development on GitHub and is fully documented here.

The CLI tool (Wren CLI) has its own repository and is the main focus of examples written for RC. The latest version 0.4.0 is available as a pre-built standalone executable for 64-bit Linux, MacOS and Windows and can be downloaded from here.

As a language mainly designed for embedding, Wren's standard library is (of necessity) quite small and I (PureFox) have therefore decided to create some additional modules to assist with writing Rosetta Code tasks so the same code does not have to be written or copy/pasted time and time again thereby bloating a task's script code unnecessarily. The ones written so far are listed below:

No.	Module name	No.	Module name
1	fmt	2	str
3	sort	4	math
5	trait	6	seq
7	date	8	rat
9	pattern	10	big
11	upc	12	matrix
13	set	14	llist
15	queue	16	complex
17	dynamic	18	ioutil
19	long	20	crypto
21	sound	22	polygon
23	srandom	24	lsystem
25	turtle	26	ellipse
27	check	28	array
29	gmp	30	ecm
31	sql	32	event
33	i64	34	perm
35	linear	36	regex
37	maputil	38	plot
39	debug	40	table
41	iterate	42	money
43	vector	44	ordered
45	psieve

To use a class or classes from a module (say fmt), you need to import them into your script with Wren code such as the following. To use more than one class separate their names with commas:

import "./fmt" for Conv, Fmt

These modules are subject to the same license as any other code submitted to Rosetta Code though contributors' user pages should be checked to see whether more permissive terms are available. If anyone wishes to add further modules, please do so using a similar model and append them to the list.

Please note that when creating a category for a new module its name should be prefixed with 'Wren-' as in 'Wren-fmt' and the library header for a task which uses the module should therefore use this name. Modules will normally have generic names and this convention allows Rosetta Code users to easily distinguish Wren modules from similarly named modules/libraries written for other languages.

There are also a number of third-party modules available for Wren of which the following have been used to write solutions for Rosetta Code tasks:

No.	Module name	No.	Module name
1	DOME	2	Raylib-wren
3	SpiderWren	4	Wren-assert
5	Wren-json	6	Wren-test
7	WrenGo	8	Wren-xsequence

For further information and licensing requirements, please consult their individual pages.
