About

The robust-lsp server provides a universal LSP interface to improve the experience of working with a project using Robust Toolbox.

Inspired by Robust YAML. However, the disadvantage of the latter is that it works exclusively in VS Code. The idea behind robust-lsp is that once you install it, you can use it wherever there is support for the LSP protocol. From VS Code and Raider to Emacs and Zed.

Capabilities

It is open to suggestion for extensions/improvements to the functionality.

Code completion:
- Prototypes
  - Fields
  - Parents (I forgot to parse interfaces in the C# codebase, so the parent field will not be prompted, sorry :3)
- Components
  - Fields
  - Icon and Sprite components have code completion for rsi in the sprite and state fields.
- Field types:
  - ProtoId
  - EntProtoId
  - bool
Moving on to the definition:
- Prototype in C# code
- Prototype parent in yaml files
Inlay hints

[!NOTE] The server is under development, so features are subject to change.

Installation

VS Code

If you're a happy VS Code user, there's an extension Robust LSP for you that can automatically load the server, after which you can get straight to work.

[!NOTE] The extension has not been tested as I am lazy, so if it refuses to load the plugin - do not throw slippers at me, I warned you.

Other editors

First, you'll need to install the server.

Windows

iwr 'https://raw.githubusercontent.com/Ertanic/robust-lsp/refs/heads/main/scripts/install.ps1' | iex

Linux

Linux hackers, you'll figure it out on your own.

MacOS

You will have to build the server from the source files.

Connect to the server

Next, you need to find out if the editor has built-in LSP support. Let's examine the example of Rider. It doesn't have built-in support through settings, unless you create an extension (and I'm too lazy to do that). That's why we are looking for any plugin that will allow us to connect the server without any fuss. A good option is to use lsp4ij.

Once you've installed lsp4ij, go to File > Settings... > Languages & Frameworks > Language Servers. Here you need to create a new server profile, to do this click on +.

Name the profile whatever you want, mine is Robust LSP. In the Command field you need to type robust-lsp. Now go to the Mapping tab, where in File type or Language you need to enter the following YAML. When you open the yaml files, the server will try to start. You can also add C# files to the triggers, it's up to your discretion.

[!NOTE] I don't know if it's the server going buggy, but it's working crookedly for me in RustRover.

Build

To build from the source files you only need rust toolchain, you can download it on the official website. The compiled binary will be in target/[release|debug]/robust-lsp(.exe).

cargo build [--release]

You will need Node.js and npm to build the VS Code plugin. The output files will be in clients/code/out/.

npm i
npm run compile

If you want to build the extension into a vsix file, you will need the vsce manager. The output will be the file robust-lsp-{version}.vsix.

npm install -g @vscode/vsce
vsce package

But I frankly don't know why you'd want to do that, so forget it.
