Since Chris only mentioned use.local.desc, I'm assuming he only meant local flags rather than use.desc also. In that case, asking what the "foo" local flag does doesn't make sense, because it does something different depending on the package you're curious about. Centralizing what feels like inherently local data seems odd to me. USE flag editors would still need to generate a complete list, though, so this would make more work for them. Chris, I'm not entirely clear what you meant by your suggestion of also dropping metadata.xml ; where would we describe local flags? Thanks, Donnie -- gentoo-dev@lists.gentoo.org mailing list

One could argue that you can't do that currently for DEPEND strings and such, so that seems like a possibly weak argument to me. Just because you can do something right now doesn't mean it was meant to be that way, or shouldn't be changed to make things better :) Either way, I would prefer (and I'm sure others will as well since it will cut down on confusion) if we pick either use.local.desc or to move them into metadata.xml. Having it possibly be in both places just seems silly. -- Mark Loeser email - halcy0n AT gentoo DOT org email - mark AT halcy0n DOT com web - http://www.halcy0n.com pgpKNKGoZLuMg.pgp Description: PGP signature

The global use.* files are convenient because it means we don't need to generate or push a cache for the data (like for metadata). If it was per package or per-ebuild we would need to generate a cache to answer queries like 'what does the "foo" flag do'. > > -- > Chris Gianelloni > Release Engineering Strategic Lead > Games Developer > > -- gentoo-dev@lists.gentoo.org mailing list

Putting paragraphs in there doesn't seem right. A single long line still fills this "requirement" for us. However, it does bring up the point. Why even have use.local.desc (or metadata.xml's tag) at all? Is there really a need for a *global* list of flags that are ebuild-specific?

Ryan Hill wrote: What do people think of this? a) Keep use.desc as it is: a list of common flags and a short general description of their meaning. Good. b) Keep use.local.desc as it is: a list of per-package flags that are specific to one to a few ebuilds (i think 5 is the number though i think 10 is more appropriate, but that's not relevant to this discussion). Again, each has a short description. c) Allow flags from use.desc to also exist in use.local.desc. In the case that a flag for a package exists in both, the use.local.desc description overrides the use.desc one. This allows a more specific per-package description of global flags. Good. d) Allow long descriptions in a package's metadata.xml, as some have begun to do already, for cases where more info is needed. For example I'd like to explain exactly what the bindist flag on freetype does and what legal implications disabling it can have. Right. Also why not also add short descriptions there, and deprecate use.local.desc when tools are converted? Placing package-local info to global files (when not needed to distinguish profiles as with package.use.mask etc) is icky. Note that the metadata.xml should be able to record per-version differences somehow. On the other hand, if there are any far-reaching changes we need made to the USE flag system - any features we wish we had or misfeatures we wish we didn't - now would be a good time to address them. I wish for use deps :P Well, addressing conflicts and implications between flags at ebuild/PM level would be also nice, but really shouldn't affect the way documentation is handled, IMHO.
