Mixxx CLI arguments error handling and autocompletion

[Dale]

Request:

If you launch Mixxx from the CLI there are a number of arguments you can start it with. At least on Linux the behaviour here is non-standard though. If you enter the incorrect syntax or misspell the argument then Mixxx will still load as normal. It should fail to load and tell the user the argument was invalid.

An addition to this which would be really nice (especially as Mixxx uses fairly long argument strings) would be to have Tab Autocompletion working on this. I wouldn't say this is quite standard in Linux but the core GNU utils do it as does some other software so I'm sure it should be possible.

Yeah, auto-complete would be nice! Or some minimal man page that lists available options.
I rarely use controller debug or different ressource path, but if I do I have to look it up in the wiki to checck the correct spelling.

mixxx --help

That works for giving you a list of the options and their basic description (at least on Linux.)

Still it should fail if typed wrong, stating "invalid argument" or similar. The autocomplete would be nice but really is just a bit of sugar coating I'm less expecting to see....

``mixxx --h`` works with all supported platforms.
On linux, ``man mixxx` should work with the (outdated) man page available @https://github.com/mixxxdj/mixxx/blob/master/build/debian/mixxx.sgml

`

man mixxx doesn't work here.

"$ man mixxx
No manual entry for mixxx
See 'man 7 undocumented' for help when manual pages are not available."

Thanks for testing.
Iirc, this should work if installed via *.deb package, if not this is a regression. Im not on linux, so cant test.

Other ways to test are listed here lp:1159150

Mixxx is installed via your Ubuntu beat ppa here:

https://launchpad.net/~mixxx/+archive/ubuntu/mixxxbetas

The methods mentioned on the linked bug report don't work either.

"$ docbook-to-man mixxx.sgml > mixxx.1
/usr/bin/nsgmls:E: cannot find "mixxx.sgml"; tried "mixxx.sgml", "/usr/local/share/sgml/mixxx.sgml", "/usr/share/sgml/mixxx.sgml"

for auto-completion we can install a file here:

/etc/bash_completion.d
