It's been almost four years since the previous release, so I'm happy to
announce that Ritex [1] 0.2 has been released today. This version features
many bugfixes an improvements, most notably:

* Array options are now supported. (Necessary to get   the @eqnarray@-style
equation alignment in this   post [2]
* Unary minus heuristics are much improved.

Here's a quick demo of the unary minus:

table{margin-left: auto; margin-right: auto;}. | @-x@                |
$$-x$$                | | @x-x@               | $$x-x$$
          | | @x--x@              | $$x--x$$              | |
@\alpha-x@          | $$\alpha - x$$        | | @\alpha\,-x@        |
$$\alpha\, - x$$      |

Sadly, just as with LaTeX itself, there are still times where you have to hint
to get the right behavior:

table{margin-left: auto; margin-right: auto;}. | @\sin-x@            |
$$\sin-x$$            | | @\sin{-x}@          | $$\sin{-x}$$
 |

 Over the years since the last release it looks like there are two new options
for generating MathML in Ruby. Itex2MML [3] has developed Ruby bindings, and
there's some other project just called MathML [4]. The big win for Ritex over
these packages, of course, is macro support:

table{margin-left: auto; margin-right: auto;}. |
@\define{\onion}{\hat{\theta}}@     | $$\define{\onion}{\hat{\theta}}$$ _-_     | |
@\define{\potato}[1]{E_\theta[#1]}@ | $$\define{\potato}[1]{E_\theta[#1]}$$ _-_ | |
@\potato{\onion}@                   | $$\potato{\onion}$$
      |

A quick @gem install ritex@ should get it for you, and you can see some more
example input/output pairs here [5].
