Hello, fellow devs!
As you might know, the Gentoo KDE project provides an overlay with KDE4
live ebuilds ("kde" in layman) and some of their dependencies.For quite some time now, our progress has been impaired by the absence of features like USE dependencies, ranged dependencies and suggested dependencies. Most of us who are working on the overlay have been using alternative package managers (PM) for quite some time now. Thus, the idea arose to go a step further and actually make good use of the capabilities they offer us. In the end, we chose to use Paludis and discussed the possibilities of a new, stable EAPI for our overlay with Ciaran McCreesh who kindly agreed to help us with that. (Thank you, Ciaran!) Ciaran will submit a patch for PMS that enables the ability to *optionally* build it with kdebuild-1 documented. Thus, we will support any package manager that implements this EAPI. This new EAPI, "kdebuild-1", consists of the following features (in addition to EAPI 1): - "-scm" support (GLEP 54) - new .kdebuild-1 suffix (basically GLEP 55) - USE dependencies, including some special operators - ranged dependencies - :* and := slot dependencies - src_uri arrows - src_test is now mandatory (unless RESTRICT'ed) - no implicit mkdir for doins - no dohtml, dohard and dosed. - no old-style virtuals (i. e. no "PROVIDE") - pkg_info on not installed packages - src_uri labels - PDEPEND "suggested:" label You'll find all the details in the following local copy of PMS with the kdebuild-1 patch applied: http://www.mailstation.de/pms.pdf For starters, we'll be using the new EAPI for live ebuilds (${PV}=-scm) only, so that users of other PMs will be able to use the rest of the overlay as before. That's exactly what the kdebuild-1 EAPI was designed to allow for. For users of the KDE overlay's live ebuilds the new EAPI currently means they will have to use Paludis but there are rumours ;) other PMs are interested as well. That's the main reason to optionally include it in PMS. For those of us working on the overlay this means we will be able to use exciting new features and hopefully make our lives easier. For Gentoo as a whole this means there's plenty of opportunity to try new stuff and learn from the experiences. -- Best regards, Wulf (Gentoo KDE Project lead)
