papandreoos,
| Code: | * app-editors/emacs
Available versions:
(18) [M]18.59-r11
(23) 23.4-r17
(24) 24.5-r5
(25) 25.3-r1 25.3-r4
(26) (~)26.1_rc1 |
app-editors/emacs-26.1_rc1 in in the testing branch. As you have it installed now, you must have unmasked it temporarily.
Read about mixing testing packages into a stable install.

You can post emerge output when you update with -t option?

yes, first i removed again emacs:25 (i also removed virtual/emacs-25. i thought it would help but it didnt) and here is the output of emerge world with -t option:
| Code: |

The problem is that virtual/emacs-26 not exists (this cause probably because emacs 26 is only in release candidate and not already stable) and app-emacs/emacs-common-gentoo depend by it.
As workaround you can uninstall app-emacs/emacs-common-gentoo

papandreoos,
emacs can be supplied to things that depend on it by several different packages.
These packages depend on virtual/emacs and virtual/emacs ensures that something that satisfies the requirement is installed.
The key part of virtual/emacs-25 is
| Code: | RDEPEND="|| ( app-editors/emacs:25
>=app-editors/emacs-vcs-25.1 )" |
so anything that depends on emacs will pull in app-editors/emacs:25 unless >=app-editors/emacs-vcs-25.1 is already installed.

don't understand your answer 
i do not have emacs-vcs-25.1 installed.
i also can't emerge app-editors/emacs-vcs-25.1 becuase it has no ebuild for this package.
also there is emacs-vcs-26 so i tried to merge it:
| Code: |
sudo emerge emacs-vcs
Calculating dependencies... done!
[ebuild N ] app-emacs/emacs-common-gentoo-1.6-r1 USE="X -games"
[ebuild N ] app-editors/emacs-vcs-26.0.91 USE="X acl alsa dbus gif gpm gtk gtk3 inotify jpeg png ssl svg systemd threads tiff xpm zlib -Xaw3d (-aqua) -athena (-cairo) -dynamic-loading -games -gconf -gfile -gsettings -gzip-el -imagemagick -kerberos -libxml2 -livecd -m17n-lib -mailutils -motif (-selinux) -sound -source -toolkit-scroll-bars -wide-int -xft -xwidgets"
[ebuild N ] virtual/emacs-25
[blocks B ] <app-editors/emacs-vcs-26.1_rc1 ("<app-editors/emacs-vcs-26.1_rc1" is blocking app-editors/emacs-26.1_rc1)

You right because app-editors/emacs has app-emacs/emacs-common-gentoo as direct dependency.
You can try to create virtual/emacs-26 in your local overlay

# Distributed under the terms of the GNU General Public License v2
EAPI=6
DESCRIPTION="Virtual for GNU Emacs"

RDEPEND="|| ( app-editors/emacs:26

papandreoos,
Gentoos virtual packages do not install any code themselves.
They are used in ebuilds when the same functionality can be provided in two or more ways.
In your example, an ebuild that requires emacs will depend on the virtual.
The virtual lists all the packages that can provide emacs.
The virtual is a logical or list, so it is satisfied if any package it lists is installed.
When the virtual is not satisfied, the first listed package in the logical or list is selected.

thanks for the explanation.
i didn't succeed with the ebuild process (local overlay) so i'll wait till it be "fixed" in gentoo.
i still can use (and do it) emacs 26 with the eselect emacs 26 so i'll ignore 25 is also installed for now . |
