Nope, I don't agree. > (maybe eix more than emerge) > Just like "emerge -vv" will print information about the ebuild > maintainers in future release, if i got that right. Lifted from metadata.xml . Jamming a 'built-in list of use flags' into ebuilds/metadata.xml first of all is vague, second of all is going to jack up the tree's size, third of all will lead to a buttload of redundant information across the tree. So... nail it down, instead of the vague "eix/emerge should do this".

Portage does you mean, since eix is just a tool that read directly from portage underlying files (and is going to get boned by portage changes to the underlying cache at some point).

What you're not groking here is that people work on A) what they find interesting B) what they think *needs* to be done. Via that ordering, the subjective bit you're throwing out is nulled; use flag display is minor compared to fixing portage's screwups from where I sit.

You've got the unix principle slightly wrong there- implicit is that if no alternative exists, the person persuing the alternative *implements* it themselves rather then riding others to do it. > also, i agree that emerge may not be the right tool for that. may be > "eix" or a new one. > what this is about, is including additional information (only one link > that will not hurt you) in the ebuilds or metadata.xml Guessing you're not aware of the cache, nor the dtd for metadata.xml Slapping stuff into the cache requires portage modifications, both for the package and for the rsync cache generation. It can be done, but the question before doing it is exactly what this is going to yield, is it really the right route, and what is going to be broken by this (since tools *do* read directly from cache entries even if it's daft to do so). > >Do you think we're all sadists? > > No, but hard to believe that you are not ignorant against people > - that like to have features you personally find useless > - that may be not using linux since 1992 and need more good > documentation to install and maintain their system > - that (therefore) do not know the linux/gentoo/portage file structure > by heart > > >Sorry, but such statements don't help your argumentation. > > Did you think the statements in Jasons first reply were all helping the > discussion? Play nice, or go play somewhere else, bluntly. You're not convincing anybody that *your* personal opinion of how it should be done is the correct way, further you're *not* going to pull that off if you're being agressive/insulting about it (I'll give you the benfit of the doubt and assume you're not intentionally trying to insult people). Others pissing you off is no reason to respond in kind, nor any way to get anything productive out of this discussion beyond it descending to a flamewar. > >>BTW, if "This is out of the domain of a package in any package > >>management system", then why do some packages print additional > >>information after emerging, like what files should be updated manually? > > > >For the user's convenience of course. > > This sounds like they are needless.

Additionally... you're proposing a retrofit of metadata into the entire tree, which is a *lot* of work (that's fact), leaving the question of what really is gained, if there was a better way, etc. Not trying to be overly harsh here, but people have pointed out why there are issues with it. Address the issues, don't fall back to rhetoric or "it should be". Check the code, look into it rather then telling others they should do it. my slightly flamey 2 cents. ~harring
