Ren-C

Ren-C is a deeply redesigned branch of the Rebol language, developed at github.com/metaeducation/ren-c.

This site is the beginning of its reference documentation. It is small for now, but it is built so that it can be trusted: every example is tested.

Tested Examples

When the site is built, each console example is pulled out of the page and run by a current Ren-C interpreter. The result has to match what the page shows, or the site doesn’t deploy.

>> reduce [1 + 2 3 + 4]
== [3 7]

That includes the examples that are supposed to fail. An example showing an error has to produce that error:

>> reduce [null]
** PANIC: Invalid use of ~null~ antiform

So when a page says something doesn’t work, that’s checked too.
