[gentoo-dev] Ebuilds for packages without a homepage?

What's the right thing to do with an ebuild's HOMEPAGE variable if there
is not any homepage? Different packages have different approaches for
this; some don't have any HOMEPAGE line (dev-util/cdecl), some set
HOMEPAGE to the empty string (app-i18n/kon2), possibly with a comment
following it (app-i18n/kcc), and some set HOMEPAGE to some string that's
obviously not a URL such as "none" (app-doc/xmltoman) or "I HAVE NO HOME
:(" (app-text/dos2unix). There don't seem to be any guidelines in the
docs, either official or unofficial, other than to put a link to the
freshmeat page or something similar, which isn't possible in my case
because there is no freshmeat page or anything similar that I know of,
so what should I do?

I think "none" could be the better workaround imho.

I vote for "none" too :) It clearly states, that HOMEPAGE is missing.
Blank HOMEPAGE is misleading.

Page is unknown, too lazy to search, what does empty HOMEPAGE exactly mean?

Then any automated tools will need to be told explicitly that "none" is
something special. With all HOMEPAGE entries being fully qualified URIs,
you can just do something like for h in HOMEPAGE ; do firefox "$h" & ;
done , which works just fine in multiple and blank homepage cases...

That there is no HOMEPAGE, in the same way that an empty DEPEND means
there are no dependencies, an empty IUSE means there are no used USE
flags and an empty SRC_URI means there are no download components.

For "unknown" or "too lazy" cases, the package shouldn't be in the tree.

I agree with Ciaran here.  exporting the explicitly empty variable is a
good thing.  If, however the variable is unset completely, then we have
an issue of laziness on a developers part.

Why?

portage substitutes "" when metadata keys are unset during depends 
export.  Seems kind of pointless requiring an empty var- yes it could 
be used for typo checks where the dev does a 

HOMEPAGe="blah"

but no other var has an actual check of that sort- to do the check 
would require mangling ebuild.sh also, which I think is kind of daft.

Repoman complains if the var is unset/empty, works for me personally.

Too bad reality doesn't match.

As an aside, when I put xsnap in the tree long ago, I just 
duplicated the SRC_URI in HOMEPAGE.  I don't know that it's any better a
solution than HOMEPAGE="", but at least it gives people something to
click on who use packages.g.o.

Hrm. KEYWORDS.missing, LICENSE.missing, DESCRIPTION.missing and
SLOT.missing are listed in 'man repoman'.

Re-read the chunks of my original email above.

The suggestion is requiring

HOMEPAGE=''

in ebuilds, which is daft due to the fact that ebuild.sh does not 
discern between an unset and empty var for exporting.  All stable 
portage (python side) sees is empty, no special flagging of unset.

The repoman checks I commented on, due to ebuild.sh not discerning 
between an unset env var and an empty one, are testing to see if it's 
empty not unset/missing.  It's pointless requiring the var to be set 
empty in the ebuild because portage (by extension repoman) doesn't
know the difference between unset and empty.

Making it aware of the difference is a bit daft also imo; a package 
that lacks a homepage I tend to think should be flagged as a warning, 
regardless if the author set the HOMEPAGE var or not.

The list of ebuilds without homepage is indeed quite shocking. When you look 
at our ebuild howto¹, the variables SLOT, LICENSE, KEYWORDS, DESCRIPTION, 
SRC_URI, HOMEPAGE and IUSE are mandatory, so all these ~3000 ebuilds do not 
adhere to our minimum quality standard. Some light on our pretty much 
non-existing QA team, please...

Please forget my earlier email. After having a closer look almost all of those 
ebuilds get the hompage set via the eclass they inherit, so Simons statement 
is pretty much void.
