Keeping package.* files sorted and tidy

[printf]

After many years of use on my 2 gentoo machines, sometimes I stumble upon instances of duplicate configurations in packages.* files.
I'm thinking about manually sorting the files periodically using linux commands, but first i was curios, if there is any tool, that does that?
Or anyone has a nice sorting technique, that takes into account special characters too?
Once i tried briefly a GUI based emerge, but I'd rather keep it absolutely bare-bones, if possible.

On a different note, my /etc/portage looks like this:

switching to package.accept_keywords would cancel portage complains.
Do you have any reason for not doing so? package.keywords based scripts maybe?

My personal liking there is directories instead of single file..
package.use & accept_keywords mostly contain package based file, e.g. one for clang, one for gcc and so on...

Remember that latest defined & read atomic package constrain will be taken into account.
So if you want # constraint depending where the ebuild is originated from, it would be advisable to deambiguate with final ::gentoo or ::overlay an the end of the package definition accordingly.
In shown configuration package.keywords will have the final word over package.accept_keywords.


Thks 4 ur attention, interest & support.

printf,

eix has some options to find redundant entries.
That's a good start. Cleaning out the rubbish.

Using directories for package.* is a doubled edged sword. You get can got duplicate entries, sometimes doing different things. That's a mess.
