The Apache 2.0 licenced source code covers the major overhaul for WebOS that was in development at Enyo around the time that HP bought, and months later abandoned, support for the operating system.
WebOS is now owned by LG, which uses it to power its smart TVs, with HP retaining underlying patents. Work on Mochi had been ongoing until the LG buyout, but with the Enyo team now working on projects for LG, the decision was taken to open it to community development.
Last week, HP settled out of court after investors filed a class action lawsuit for lost earnings after HP had abandoned WebOS, agreeing to pay $57m.
The Mochi code is interesting both as an opportunity for open source development and as a glimpse of an alternative view of the future, with its flat linear graphics design predating the iOS 7 or Android Holo user interfaces.
Before its release, the Enyo team spent time preparing it for its open source future by "lining up community members to act as maintainers, fixing font licensing issues, and gathering up the internal design documents that would let our community developers understand the ideas behind the UI and see what's yet to be implemented from the original vision".
LG said it hasn't ruled out using WebOS on a device in the future, and in the meantime, the code is available now on Github with advisory support available from the Enyo team. µ
