equery uses gives back special flags in the use-flag list: # equery u dev-php/xdebug [ Legend : U - final flag setting for installation] [ : I - package is installed with flag ] [ Colors : set, unset ] * Found these USE flags for dev-php/xdebug-2.2.1: U I - - php_targets_php5-3 : Build against PHP 5.3 + + php_targets_php5-4 : Build against PHP 5.4 However, we cannot search for them: # equery h php_targets_php5-4 * Searching for USE flag php_targets_php5-4 ... # It would be nice, if we could do that too. Possibly not by default, but with an extra option which could be useful even when it would take much longer to perform.
You can use equery's "has" module to find them. It is just a generalized string search that I took from the hasuse code. It searches the specified environment variable for the string. equery has USE php_targets_php5-4

It does not work, neither this (the way it's told in the ebuild): # equery a USE_PHP php5-4 * Searching for USE_PHP php5-4 ... # nor this (the way we need to specify in make.conf): # equery a PHP_TARGETS php5-4 * Searching for PHP_TARGETS php5-4 ... # According to the documentation, "has" searches in /var/db/pkg, isn't that the place for the installed ebuilds?
Never mind what I just wrote, I'm dumb. Hasuse actually searches for installed packages only too (and it would be cool to be able to search for non-installed packages too (for the existence of the flag), but that's offtopic)
Meh, this whole bug is invalid then, it simply works as it is intended. Sorry. Close it as INVALID.

But they all have the option to search the entire tree and/or overlays. big_daddy brian # equery has -h List all installed packages that match for a given ENVIRONMENT variable Usage: has [options] env_var [expr] options -h, --help display this help message -I, --exclude-installed exclude installed packages from search path -o, --overlay-tree include overlays in search path -p, --portage-tree include entire portage tree in search path -F, --format=TMPL specify a custom output format TMPL a format template using (see man page): big_daddy brian # equery hasuse -h USE python_targets_python2_7 List all installed packages that have a given USE flag Usage: hasuse [options] USE-flag options -h, --help display this help message -I, --exclude-installed exclude installed packages from search path -o, --overlay-tree include overlays in search path -p, --portage-tree include entire portage tree in search path -F, --format=TMPL specify a custom output format TMPL a format template using (see man page): $location, $mask, $mask2, $cp, $cpv, $category, $name, $version, $revision, $fullversion, $slot, $repo, $keywords big_daddy brian # The "has" module can not search for USE in the portage tree, it does not exist, it is only in the installed pkgs. The other thing to remember is that in IUSE the variables are not yet use expanded, so a string search there needs to be tailored for the un-expanded USE flag. To use "hasuse" or "has" to search for use_expanded flags in the installed pkgs. They have to be in the fully expanded form. Just like I posted in the example I gave in comment #1. search installed pkgs only: equery hasuse php_targets_php5-4 search the whole tree: equery hasuse -p php_targets_php5-4 ^NOTE in the 2nd example that you need to specify the fully expanded use_exapnd flag ex: big_daddy brian # equery hasuse -p php_targets_php5-4 * Searching for USE flag php_targets_php5-4 ...

(In reply to comment #5) > equery hasuse -p php_targets_php5-4 That was exactly what I was looking for. Thank you Brian for pointing this out. equery works perfectly. Sorry for the noise.
