[gentoo-user] /etc/portage/package.keywords syntax

[Thanasis]

Suppose I want to set the series of  kernel sources:
gentoo-sources-2.6.28*
with the ~x86 keyword.
What should I write in /etc/portage/package.keywords ?

I am certain that is thoroughly covered in the documentation, or most
any google search, so I pray thee, RTFM.

Yes, I know, but sometimes, *obvious* things my escape attention... :-\

I was trying with just
=gentoo-sources-2.6.28* ~x86
...and emerge was complaining.

Thanks. :-)

~sys-kernel/gentoo-sources-2.6.28 ~x86

or, if you are running x86,

~sys-kernel/gentoo-sources-2.6.28

What is the meaning of the "~" in front ?
Is it documented?

same as =...2.6.28*

but I disagree with the second suggestion, because no keyword means any keyword.

Not quite, 2.6.28* could also match 2.6.280-r3.

No it doesn't, it means use the ~arch version of whatever you have in
ACCEPT_KEYWORDS.

You both should read the manual. I have copied some excerpts from relevant
man pages, and even surrounded the most relevant parts with the word
"MYEMPHASIS". Not everyone has this patience.
From man portage:

package.keywords
       Per-package  KEYWORDS.   Useful for mixing unstable pack-
       ages in with a normally  stable  system  or  vice  versa.
       This  will  allow  ACCEPT_KEYWORDS  to be augmented for a
       single package.

       Format:
       - comment lines begin with # (no inline comments)
       - one DEPEND atom per line followed by additional KEYWORDS
<MYEMPHASIS>
       - lines without any KEYWORDS imply unstable host arch
</MYEMPHASIS>
       Example:
       # always use unstable libgd
       media-libs/libgd ~x86
       # only use stable mplayer
       media-video/mplayer -~x86
       # always use unstable netcat
       net-analyzer/netcat

       Note:
       In addition to the  normal  values  from  ACCEPT_KEYWORDS
       package.keywords supports three special tokens:

       *  package is visible if it is stable on any architecture
       ~* package is visible if it is in testing on any architecture
       ** package is always visible (KEYWORDS are ignored completely)

       Additional  Note:  If  you encounter the -* KEYWORD, this
       indicates that the package is known to be broken  on  all
       systems  which are not otherwise listed in KEYWORDS.  For
       example, a binary only package which  is  built  for  x86
       will look like:

       games-fps/quake3-demo-1.11.ebuild:KEYWORDS="-* x86"

       If  you wish to accept this package anyways, then use one
       of the other keywords in your package.keywords like this:

       games-fps/quake3-demo x86

From man 5 ebuild:

DEPEND This  should  contain a list of all packages that are required for the program to com-
   pile.

   DEPEND Atoms
      A depend atom is simply a dependency that is used by portage  when  calculating
      relationships  between  packages.  Please note that if the atom has not already
      been emerged, then the latest version available is matched.

      Atom Bases
         The base atom is just a full  category/packagename.   Hence,  these  are
         base atoms:

         sys-apps/sed
         sys-libs/zlib
         net-misc/dhcp

      Atom Versions
         It  is  nice  to  be more specific and say that only certain versions of
         atoms are acceptable.  Note that versions must be combined with a prefix
         (see  below).   Hence  you  may add a version number as a postfix to the
         base:

         sys-apps/sed-4.0.5
         sys-libs/zlib-1.1.4-r1
         net-misc/dhcp-3.0_p2

         Versions are normally made up of two or three numbers separated by peri-
         ods,  such  as 1.2 or 4.5.2.  This string may be followed by a character
         such as 1.2a or 4.5.2z.  Note that this letter is not meant to  indicate
         alpha,  beta,  etc... status.  For that, use the optional suffix; either
         _alpha, _beta,  _pre  (pre-release),  _rc  (release  candidate),  or  _p
         (patch).  This means for the 3rd pre-release of a package, you would use
         something like 1.2_pre3.  The suffixes here can be  arbitrarily  chained
         without limitation.

      Atom Prefix Operators [> >= = <= <]
         Sometimes  you want to be able to depend on general versions rather than
         specifying exact versions all the time.  Hence we provide standard bool-
         ean operators:

         >media-libs/libgd-1.6
         >=media-libs/libgd-1.6
         =media-libs/libgd-1.6
         <=media-libs/libgd-1.6
         <media-libs/libgd-1.6

      Extended Atom Prefixes [!~] and Postfixes [*]
         Now to get even fancier, we provide the ability to define blocking pack-
         ages and version range matching.  Also note  that  these  extended  pre-
         fixes/postfixes may be combined in any way with the atom classes defined
         above.  Here are some common examples you may find in the portage tree:

         !app-text/dos2unix
         =dev-libs/glib-2*
         !=net-fs/samba-2*
         ~net-libs/libnet-1.0.2a
         !!<sys-apps/portage-2.1.4_rc1

         ! means block packages from being installed at the same time.
         !! means block packages from  being  installed  at  the  same  time  and
         explicitly disallow them from being temporarily installed simultaneously
         during a series of upgrades. This syntax  is  supported  beginning  with
         EAPI 2.
         *  means  match any version of the package so long as the specified base
         is matched.  So with a version of  '2*',  we  can  match  '2.1',  '2.2',
         '2.2.1', etc... and not match version '1.0', '3.0', '4.1', etc...
<MYEMPHASIS>
         ~  means  match  any  revision of the base version specified.  So in the
         above  example,  we  would   match   versions   '1.0.2a',   '1.0.2a-r1',
         '1.0.2a-r2', etc...
</MYEMPHASIS>
      Atom Slots
         Beginning  with  EAPI 1, any atom can be constrained to match a specific
         SLOT. This is accomplished by appending a colon followed by a SLOT:

         x11-libs/qt:3
         ~x11-libs/qt-3.3.8:3
         >=x11-libs/qt-3.3.8:3
         =x11-libs/qt-3.3*:3

      Atom USE
         Beginning with EAPI 2, any atom can be constrained to match specific USE
         flag  settings. When used together with SLOT dependencies, USE dependen-
         cies appear on the right hand side of SLOT dependencies.

         Unconditional USE Dependencies

                Example         Meaning
                -----------------------------------------------------------

                foo[bar]        foo must have bar enabled
                foo[bar,baz]    foo must have both bar and baz enabled
                foo[-bar,baz]   foo must have bar disabled and baz enabled

         Conditional USE Dependencies

                Compact Form   Equivalent Expanded Form
                -----------------------------------------------------

                foo[bar?]      bar? ( foo[bar] ) !bar? ( foo )
                foo[!bar?]     bar? ( foo ) !bar? ( foo[-bar] )
                foo[bar=]      bar? ( foo[bar] ) !bar? ( foo[-bar] )
                foo[!bar=]     bar? ( foo[-bar] ) !bar? ( foo[bar] )
