Description Pacho Ramos gentoo-dev 2012-01-18 19:08:21 UTC
I couldn't find a bug for this :-/

Currently, we need to manually DEPEND, for example, on app-arch/xz-utils when our distfiles use .xz. Would be nice if this DEPEND could be added automatically when needed instead of needing to add this DEPEND on a lot of ebuilds

Thanks  a lot

Reproducible: Always

Alas, having a file extension in SRC_URI doesn't mean something will want to extract that using 'unpack'.

I think there's a bug around somewhere for adding a magic/unpack-xz dep so you don't need to hard-code the package name, at least (and so package manglers can use other tools).

i believe you mean bug 399019
Comment 3 Pacho Ramos gentoo-dev 2012-04-28 08:42:17 UTC
Then, should we simply use unpacker.eclass for xz? Looks like this problem is already handled by it :-/
Comment 4 Arfrever Frehtes Taifersar Arahesis 2012-11-26 05:10:14 UTC
Initial implementation of automatic unpack dependencies is now available in Portage:;a=commitdiff;h=44f2b8f9603964abe230cfe8ef75831a82855da5

What syntax in SRC_URI should be used to specify that a file should not be unpacked and dependency on unpacker should not be automatically added?
Maybe "-" after filename?
SRC_URI=" - -> file3.xz -
    doc? ( - )
    examples? ( - )
In the above example, only "${unpacker_for_gz} doc? ( ${unpacker_for_lha} )" would be automatically added to DEPEND.

Is there a reason to keep this one open? I feel like we're not supposed to make PMS reliant on any specific package names.
