Missing whitespace in completion menu

[Valloric]

Look at the first 4 entries in the completion menu. The name of the fields of the struct are right next to the type of the field, without any whitespace in between. Kinda hard to read.

In case the screenshot is not enough to figure out the root cause of the issue, you can repro like so:

1. Set up ycmd with ./install --racer-completer so that it has Rust support.
2. Open this file (after cloning the repo) and scroll to line 100. Type node. above it. That will produce the above picture.

I tried to reproduce the error, however I can't get rust completion to work:
I have this error:

Any ideas?

I am on Arch Linux with Rust 1.11.0, latest ycmd

That looks like we need a better error message somewhere. Seems like a 500 response from racerd. @jwilm Thoughts? The debugging experience here could be better.

@ptrv I think you'll need to set up the rust source path var.

[Valloric]

For reference, here's how I set up emacs-ycmd.

[ptrv]

I am getting these errors with having set up the rust source path var.

The error log:

ERROR:iron::iron: Error handling:

}
Error was: Error { repr: Custom(Custom { kind: Other, error: NotSupported }) }

[jwilm]

There's a bug in one of racerd's dependencies where it refuses to cooperate for certain terminals (or lack of terminal). Really need to publish an update for that...

[jwilm]

I just pushed a branch to racerd called without-logger which should make that error go away. A little more work needs to be done to publish a new version (actually want some form of logging), but this should allow you to get some completions @ptrv.

@jwilm Thanks for the without-logger branch. I checked it out and was able to get completions and reproduce the issue mentioned by @Valloric.
