Tramp support

[juergenhoetzel]

Would you accept a PR to add Tramp support for remote editing? Requires:

1. Use start-file-process instead of start-process
2. Handle multiple completion processes
3. Dissect buffer-file-name before passing commands to the completion process
4. Convert filenames back to tramp filenames when receiving responses from the completion process

Wow that would be pretty cool. Wouldn't it require bringing all the files in the project over locally though so that fsautocomplete can find them?

[juergenhoetzel]

The fsautocomplete process will be started on the remote host by start-file-process which is already tramp-aware. fsharp-mode would have to keep track of relation between fsharp-mode buffers and their corresponding fsautocomplete process.

I thought of makeing fsharp-ac-completion-process an alist instead of a single value containing the fsautocomplete process.

For example, when having a local and a remote/tramp fsautocomplete process:

((nil . #<process fsharp-complete>) ("/ssh:juergen@myhost.domain:" . #<process fsharp-complete-2>))

This is inspired by rtags, a nice c++ indexer, which is already tramp-aware.

Wow! I didn't know there was support for that. It does assume that you have mono on the remote host. Do you also copy over fsautocomplete? It sounds plausible. I would definitely accept a working patch as long as the local mode isn't affected negatively.

[juergenhoetzel]

I assumed trampUsers would adjust tramp-remote-path and setup fsautocomplete for themselves. A hint (if it's not found on the remote host) would be a sufficient advice for a typical Emacs user.

To copy over fsautocompletewould be a option but will make the code more complicated/error-prone.

[rneatherway]

OK, with documentation sounds fine to me.

[juergenhoetzel]

Thanks for your feedback. I will setup a tramp branch in the coming days.

[rneatherway]

Wonderful, I look forward to the feature!

Jason started the "screecast thing" 😄

You can now edit multiple projects on multiple hosts.

This looks amazing! A gif is worth a thousand words etc :)

Sorry I lost track of this one. It seems it conflicts now, but hopefully trivially. Would you mind merging/rebasing and I'll get it in and release?

[juergenhoetzel]

No worries. I will rebase.

[juergenhoetzel]

I just rebased. #66

[rneatherway]

Great, merged.
