I wrote a patch for euse (current revision from SVN (398)). The patch adds an option (-I/--info-installed) which is similar to --info/-i but gives some information about the installed packages matching the passed USE flag(s). On global USE flags all packages matching the USE flag that are printed will be displayed additionally. The USE flag is even displayed if there was no installed package found. On local USE flags only descriptions for installed packages will be printed. I think this option is very useful if one wants to check the impact of some USE flags on the current system, i.e. if they could be enabled or disabled globally. Example: arandes@T22 ~ $ euse -i gnutls nodrm global use flags (searching: gnutls nodrm) ************************************************************ [- ] gnutls - Adds support for net-libs/gnutls (TLS 1.0 and SSL 3.0 support) local use flags (searching: gnutls nodrm) ************************************************************ [- ] nodrm (app-text/pdftk): Decrypt a document with the user_pw even if it has an owner_pw set [- ] nodrm (app-text/xpdf): Disable the drm feature decoder. arandes@T22 ~ $ euse-modified -I gnutls nodrm global use flags (searching: gnutls nodrm) ************************************************************ [- ] gnutls - Adds support for net-libs/gnutls (TLS 1.0 and SSL 3.0 support) Installed packages matching this USE flag: net-libs/libetpan net-wireless/wpa_supplicant mail-mta/msmtp net-misc/curl local use flags (searching: gnutls nodrm) ************************************************************ [- ] nodrm (app-text/xpdf): Disable the drm feature decoder.

Created attachment 145472 [details, diff] The patch described.
Created attachment 145496 [details, diff] euse-info-installed-2.patch Altogether attachment #145472 [details, diff] is good work in keeping with the style of euse. Nevertheless, here are some improvements: 1) Use equery list instead of eix so as not to draw in unnecessary dependencies. 2) Replaced some bare word loops with whitespace-friendly list handling mechanisms. 3) Replaced a lot of subshells and pipes with more terse/lower overhead options. Trivial changes: - Added the -I option to --help and made some whitespace changes for readability (please confirm whether or not I described the new option adequately). - Changed the copyright date. TODO: - Do we want to increase the version number? - Update the man page
