Startup on random port, use `.psc-ide-port`

[natefaubion]

Other psc-ide plugins startup on a random port, and tag the port in a .psc-ide-port file. A global config means you can only have one instance running at a time.

I've been thinking about it for a while, and we are really missing that feature. For the moment I have an autocommand which changes the port number:

    au BufRead $HOME/repos/gravicus/ospreyui/** let psc_ide_server_port = 4343

You can have local .vimrc in project directory with let g:psc_ide_server_port = PORT_NUMBER which I'm using extensively. I think that random port can be used, but only when psc_ide_server_port is not defined.

Yes, that's a good point.

Oh, my, I'm an idiot. I have this working since December 2016 (on a fork at https://github.com/kika/psc-ide-vim) and I never submitted a PR. I'll merge the upstream and submit.

[coot]

Great, then it's battle tested :)

I've merged my changes but can't get through testing phase yet. I'm seeing a strange bug, which seems to be not related to port selection. Sometimes (typically when I hit TAB to get the completion) vim rescans the imports and suddenly reformats all my import lists. I've made a few 2-line changes to my sources which caused 20+ line commits, because of the changed import lists (they just got rearranged, nothing changes semantically). Any ideas?

[coot]

That's not a bug, that's a feature of purs ide. It formats imports when one is adding ones and we run it in CompleDone autocommand to import the identifier. You can turn it off though.

Hm, but I'm not adding anything, I just write some code.
