Version of VSCode: 1.11.2
Version of the extension: 0.3.14
OS: Windows 10

Description:

When there is a space in path, racer crashes.

Output of the "Rust logging" channel:

WARNING: Legacy Mode Manager: CompletionManager: restart
DEBUG: Legacy Mode Manager: CompletionManager: stop
DEBUG: Legacy Mode Manager: CompletionManager: start: enter
DEBUG: Legacy Mode Manager: CompletionManager: start: racerPath=C:\Users\user name\.cargo\bin\racer.EXE

Related issue: nodejs/node#7367
There is no workaround currently, because path always gets stripped by FileSystem.findExecutablePath.

@BusyJay,
If you use Windows 10, you can make a symbolic link: https://www.howtogeek.com/howto/16226/complete-guide-to-symbolic-links-symlinks-on-windows-or-linux/

Sorry not making my point clear. What I mean is that we can't quote the path in configuration to make it recognized when spawning the racer process. I did get it working by specified a new path without any space in it.

I got your point.
I showed you a workaround.

This issue happens with a fresh install of vscode-rust while letting it install all related tools through VSCode, if the user path on Windows has a space in it.

I've tried to manually set rust.rustLangSrcPath and rust.racerPath to symlinks without spaces, but it seems they have no effect. What configuration am I supposed to change so that I can change what paths are used when invoking racer?

@TheRealHnefi,
You changed the correct parameters.
It should work.
