started converting to use optparse-applicative This is a work in progress. It compiles and is able to do basic command dispatch, including git autocorrection, while using optparse-applicative for the core commandline parsing. * Many commands are temporarily disabled before conversion. * Options are not wired in yet. * cmdnorepo actions don't work yet. Also, removed the [Command] list, which was only used in one place. 2015-07-08 16:33:27 +00:00			`cmd :: Command`

fix inversion of control in CommandSeek (no behavior changes) I've been disliking how the command seek actions were written for some time, with their inversion of control and ugly workarounds. The last straw to fix it was sync --content, which didn't fit the Annex [CommandStart] interface well at all. I have not yet made it take advantage of the changed interface though. The crucial change, and probably why I didn't do it this way from the beginning, is to make each CommandStart action be run with exceptions caught, and if it fails, increment a failure counter in annex state. So I finally remove the very first code I wrote for git-annex, which was before I had exception handling in the Annex monad, and so ran outside that monad, passing state explicitly as it ran each CommandStart action. This was a real slog from 1 to 5 am. Test suite passes. Memory usage is lower than before, sometimes by a couple of megabytes, and remains constant, even when running in a large repo, and even when repeatedly failing and incrementing the error counter. So no accidental laziness space leaks. Wall clock speed is identical, even in large repos. This commit was sponsored by an anonymous bitcoiner. 2014-01-20 08:11:42 +00:00			`seek = withWords start`

remove command type definitions These were a mistake, they make the type signatures harder to read and less flexible. The CommandSeek, CommandStart, CommandPerform, and CommandCleanup types were a good idea, but composing them with the parameters expected is going too far. 2011-09-15 20:50:49 +00:00			`start :: [String] -> CommandStart`
better multiword parameter handling This way, individual words as entered on the command line are available to commands. 2011-05-16 16:25:54 +00:00			`start ws = do`

update for git-annex branch stop changing gitattributes on init create git-annex branch on init ugly special case for init in a bare repository goes away, yay! git annex init is also faster, at least in a large existing repo, as it does not need to run the slow 'git add' 2011-06-22 20:03:26 +00:00			`next $ return True`
