rls support

[alexsaveliev]

addresses #11, I have tested the following LSP requests on https://github.com/RalfJung/rust-101:

• hover
• go to definition
• find references

What is the current status of getting this support merged in?

LGTM

I remember we talked about this one before - either approach seems fine, I just worry about the performance implications of this approach.

__lines and __content will be maps that contain every file and every file -> line mapping for all references simultaneously, which seems like it could blow up memory usage.

That being said, it's easier to debug and reason about, so can understand that approach. And, it's just text.

Have you tried on an example with 100 reference files (some stdlib thing)?

@uforic sorry for this, your commits addressing this were lost by mistake, I have restored them now.

Does anyone have a sec to explain how this works? I tried installing the latest checkout from git and I see this in the console when I try to open a rust file:

2017-03-06 10:26:35,711: 140737142133696: DEBUG: Looking for client for extension rs in /Users/jturner/Source/httparse
2017-03-06 10:26:35,712: 140737142133696: DEBUG: Extension rs is not supported yet

Are there additional steps I need to do for rls support?

@jonathandturner please try to:

• go to "preferences -> Sublime LSP connector -> plugin settings - user"
• add there the following snippet:

{
    "clients": [
        {
            "binary": "/full/path/to/rls/binary",
            "file_exts": ["rs"]
        }
    ]
}

• restart Sublime

@alexsaveliev - great! I had to do a few workarounds to get it to work, but your tip helped me.

In case anyone was curious, I had to make a script:

#!/bin/sh
cargo run --release --manifest-path /Users/jturner/Source/rls/Cargo.toml

And then add this to my "preferences -> Sublime LSP connector -> plugin settings - user":

{
    "clients": [
        {
            "binary": "/Users/jturner/Source/rls/helper",
            "file_exts": ["rs"],
            "path_additions": ["/Users/jturner/.cargo/bin"]
        }
    ]
}
