What is WebOS Ports?
Basically, it is the (Open) webOS "Community Edition" project. You will see some old references to WOCE for that reason.
Read about the supported devices here.
What is Open webOS?
When HP pulled the plug on what was left of Palm, it produced an open source version of the webOS that ran on the HP Touchpad. That is Open webOS. LG, who bought the Palm division off HP, sponsor it now.
We have some cool material on it here.
What is LuneOS?
LuneOS is the name of WebOS Ports' Open webOS. Lune refers to the user interface in legacy webOS, LunaSysMgr.
What is LunaCE?
Luna Community Edition. It is a Touchpad thing.
rwhitby August 2012:
LunaCE (formerly UberLunah) is a collection of all the best LunaSysMgr improvements for the HP TouchPad, rolled into a single installation package.

Build and Install LuneOS
For an easy life, develop on Linux. Ubuntu 12.04 LTS 64-bit works well.
Instructions for building (or just downloading) and installing an image can be reached by selecting a target device from the Devices page. Notice that there is a LuneOS VirtualBox Emulator which you can use instead of a target device.
Build System Overview
I assume that the build system is based on the Open webOS one.
Set-up is automated
$ wget https://raw.github.com/webOS-ports/webos-ports-setup/testing/Makefile $ make setup-webos-ports
(but do follow the proper instructions for your device).
You bitbake a "recipe". This is a simple text file of metadata with the extension .bb indicating how to fetch, build and install something. The system is very modular. One recipe depends on another and there are hundreds of recipes involved in our build.
The particularly interesting recipes for our purposes, such as
webos-ports-dev-package, are in
Repository Layout might make some sense to you now!
The Porting Guide sheds quite a lot of light on this too.
So let's say you have built
webos-ports-dev-package, installed it on a device and had a play around with it. How can you change it?
Start with a browse around the
meta-webos-ports layer folder (on your build machine). Its
conf/layer.conf is interesting. This is where we pick up Open webOS from LG and then customise it. The luneos "distro platform codename" gets set in the file
webos.inc for example.
webos-repositories.inc looks pretty interesting too.
You could change something in there and bitbake again to see what happens. (Will your change be incorporated or overwritten?)
If you have made a worthwhile change, our Submitting Contributions instructions tell you how to get it pulled into the main line.
