update the readme

revert the readline workaround

drop REG_BASIC It doesn't seem to be widely available (at least musl doesn't have it) and it's the default anyway.

restructure project and switch build system use by default the OpenBSD mk infrastructure to build and test all the kamid components.

remove comment

improve draw_bar cache tty_width to avoid calling ioctl in a loop and handle cases when stdout is not a tty.

adjust get to use walk_path

make sure we don't draw a bar larger than the screen if p->done goes up, way over p->max, we end up with perc being > 100. in this case, reporting the correct percentage is fine, but drawing a bar larger than the screen is not. The bar could still "overflow" and occupy a second line, but only if the percentage number takes more then 4 digits, so it's unlikely.

fix cd Walk can be successful in various conditions where cd has to fail. For instance, we may have reached a file or we couldn't walk all the required components. In these "soft-fail" cases, the walk has mutated the fids, so to abort the cd we have to do a walk using a second fid and then clunk the old or new one depending on if it was _completely_ successful or not. Another option may be to track the number of walked path and attempt to walk '..' the right amount of times, this would saves a Tclunk in the case the walk succeeded and require a slightly bigger 9P packet to be sent in the failure case. It would complicate the walk_path API though, so I've not chosen this option.

make pwdfid a variable

fix two bugs in expect - looking for Terror doesn't make sense, it's Rerror - consume the tag before reading the error string

simplify walk_path interface

ftp: draft `cd' command

implement barebone get to implement the get command: - implement do_stat and do_read - implement a simple progress bar

add tstat
