johnson version 1.2.0 has been released!

Johnson wraps JavaScript in a loving Ruby embrace. It embeds the
Mozilla SpiderMonkey JavaScript runtime as a C extension. This release
squashes many, many bugs and segfaults.

Changes:

1.2.0 / 2010-01-25

  • Add an API for registering custom conversions.
  • Subclass Runtime, don’t delegate.
  • Make builds a bit more robust, especially on Snow Leopard.
  • Handle UTF-8 conversion better. Also, treat JS strings as UTF-16.
  • Add small bits of API doco.
  • Plug tons of root leaks.
  • Make Function.prototype.apply handle Ruby arrays.
  • Remove Rails EJS support, it was a joke to begin with.
  • Whitespace, formatting, and organization cleanups.

Could you talk about some of the potential use cases for this?

Automated JavaScript testing through existing Ruby interfaces, e.g.
RSpec.

blue-ridge is an example. It’s a packing of a several projects that
provides an rspec-like environment for JS. It currently uses Rhino, the
Java JS interpreter, but there are efforts underway to make it work with
Johnson/SpiderMoneky. That will require the next version of Johnson,
tentatively, 2.0.0, but that’s been under development for quite some
time so there should be a prereleases of it before too long.

I do a lot of JS testing, using Johnson and other dependent gems.
There’s the env-js project and the envjs gem that provide a browser
environment, e.g., a window object, based on Johnson. Then there’s jazrb
which combines the Jasmine (rspec-like) BDD framework with envjs.
jslintrb is a Johnson-based ruby driver for Crockford’s jslint. And I
have a bastardized version of watchr that provides autotest-like
environment for jazrb and jslint … (and haml and sass …)

FWIW, none of this is integrated with Rails at this point …
