2013-01-03parseopts: remove superfluous continue/shift statementsDave Reisner
Fun fact about bash: the below is valid and will only ever print 'a'! fn() { continue 2 } for x in {1..5}; do for y in {a..e}; do echo "$y" fn done done Signed-off-by: Dave Reisner <dreisner@archlinux.org> Signed-off-by: Allan McRae <allan@archlinux.org>
2012-04-24scripts/library: introduce parseoptsDave Reisner
This will replace our current options parser used in pacman-key, makepkg, and ideally elsewhere. It follows heuristics closer to that of GNU getopt long (and thus pacman itself), with the exception that it does not allow for options with optional arguments. Due to the way this parser will be used, this sort of functionality will not be needed. Instead of relying on eval+set, options are normalized into an array, OPTRET, which callers should expect to be populated after returning from parseopts. This avoids problems with quotes and spaces in arguments, assuming that the user quotes properly when passing into the application. A new test harness for parseopts is added in test/scripts.
