* Usage messages: show possible option valuesEd Santiago2020-01-08
| | | | | | | | | | | | | | | | | ...in a consistent manner: ("a"|"b"|"c") This makes it possible (and easy) for zsh completion to pick those out of the --help messages and offer them as values when user hits TAB. I chose this format because it's an already-existing convention in cmd/podman/common.go. Also: removed two duplicate "default: x" messages (Cobra displays those automatically where a non-null default is specified). Signed-off-by: Ed Santiago <santiago@redhat.com>
* zsh completion: ignore multi-line output in FlagsEd Santiago2019-12-23
| | | | | | | | | | | | | PR #4475 introduced an interesting twist on --help: a help string that spans multiple lines. This broke zsh completion. I'm not keen on that multi-line output, but it shouldn't break completion. Fix is simple: look only for flag lines beginning with '-', filter out anything else.

* zsh completionEd Santiago2019-03-13
Weekend hack by someone who doesn't grok zsh completion but who finds it deeply offensive that most completion files have an unmaintainable duplication of options and arguments. The idea behind this one is to discover the command line using --help, with a few hardcoded helpers for discovering containers, images, pods, and figuring out which args take files/dirs as args. Working remarkably well. I am using this in my daily routine and wondering how I ever managed without it. It's not perfect -- a future version can perhaps show only stopped containers for podman rm, only running ones for podman stop -- but ROI seems low on that given my limited zsh completion skills. Sadly, I can't figure out how to write a regression test suite for this. It would be lovely to have a list if partial command lines and expected completions, because the history of this change is that (seemingly) minor tweaks in one place cause breakage in another. Does anyone know of such a framework? Still... working well enough to ship, IMO. Signed-off-by: Ed Santiago <santiago@redhat.com>
