From f61f075b1cd4c226d1633abd383565934bea2f0d Mon Sep 17 00:00:00 2001 From: Dave Reisner Date: Sun, 8 Apr 2012 14:51:28 -0400 Subject: pacman-key: adopt parseopts for option parsing This requires an ugly amount of reworking of how pacman-key handles options. The change simply to avoid passing keys, files, and directories as arguments to options, but to leave them as arguments to the overall program. This is reasonable since pacman-key limits the user to essentially one operation per invocation (like pacman). Since we now pass around the positional parameters to the various operations, we can add some better sanity checking. Each operation is responsible for testing input and making sure it can operate properly, otherwise it throws an error and exits. The doc is updated to reflect this, and uses similar verbiage as pacman, describing the non-option arguments now passed to pacman-key as targets. Similar to the doc, --help is reorganized to separate operations and options and remove argument tokens from operations.
