Major progress has been made towards Eclipse’s web-tooling home Orion, as they prepare for 1.0

We’ve been following the progress of Eclipse’s web-tooling
platform Orion with eagle eyes, since it first surfaced last year,
and it seems that the 30-strong developer team is well on their way
towards a projected Autumn major release.

Eclipse Orion 0.5.1 M1 gives a glimpse at some of the ideas
planned for the platform trying to build a thriving hub for open
web tool development, in its own right. Billed as a ‘tooling

as well as visiting the impressive site behind it all for
a demo. Visiting OrionHub is
also a good move to get started.

Plans are afoot to provide at least support for Python according
to Arthorne as well, nicely complementing the main options of
JavaScript, CSS and HTML tooling. Even if you aren’t particularly
interested in building web applications, you should definitely
monitor the progress of this exciting project as it goes for the
big-time later this year.
