Details

In pacman.conf it would be useful to add a NoExtractWhitelist= or NoExtractException= directive.

i.e.
NoExtract = usr/share/locale/*
NoExtractException = usr/share/locale/en_US/*

The use case I have in mind for this is the /usr/share/locale/ directory.
On my laptop I have no problem with this directory, but I install arch to usb keys frequently and
it would be good to be able to blacklist the the 100MB+ and ~2500 files that I don't use w/o having to add every locale
other than my own to the NoExtract line.
This task depends upon

I recommend using localepurge: https://aur.archlinux.org/packages.php?ID=11975
It does exactly what you want.

Thanks for the link Greg, unfortunately it doesn't do what I need.

I want to prevent the locale files for other languages from ever being written.
I want to save write cycles and wasted time on my flash drives. Localepurge, according
to what I've read, waits until after your package manager finishes and then cleans up.
I could add an inotify watch to do that, but it would actually write to the drive even
more.

Also, my proposed solution would be generally useful. I can't think of any other case right now
but I'm sure it would prove itself in other use cases.

A better alternative might be to enable (Perl) regular expressions for NoExtract. Your use-case might be solved with negative look-aheads then:

NoExtract = usr/share/locale/(?!en_US)*

The attached patch adds the possibility to use extended Perl regular expressions for NoExtract.
