# LanguageServer.NET

A .NET implementation of [Language Server Protocol](https://github.com/Microsoft/language-server-protocol/blob/master/protocol.md) infrastructure library for VSCode, and hopefully, might also be used with other IDEs that support Language Server Protocol. Still work in progress and API is subject to change.

Based on [CXuesong/JsonRpc.Standard](https://github.com/CXuesong/JsonRpc.Standard), this .NET Standard library intends to provide basic interfaces and data structures so that you can write a language server in C#, build it on .NET Core and, with the help of the client-side code of [Microsoft/vscode-languageserver-node](https://github.com/Microsoft/vscode-languageserver-node), use it in VSCode.

For an actual (WIP) [Wikitext](https://en.wikipedia.org/wiki/Wiki_markup) language server based on this library, please take a look at [CXuesong/MwLanguageServer](https://github.com/CXuesong/MwLanguageServer).

The library is now available on NuGet. To install the package, run the following command in the Package Manager Console

```powershell
Install-Package CXuesong.LanguageServer.VsCode -Pre
```

## To set up the demo

You may need Visual Studio 2017 to build the demo.

1.  Open `DemoLanguageServer` in VS, choose `Debug` profile, and build the project.
2.  Open `Client\VsCode` folder in VSCode.
3.  Run `npm install` in the terminal.
4.  Press F5 and a new VSCode window (Extension Development Host) should show.
5.  Open a folder in the new VSCode window, and create a new file.
6.  Change the file language to `Demo Language`
7.  Then your editor will work as shown in the screenshot. Enter `.net core` in the editor and see what happens.

To debug the server application, you may wish to turn `WAIT_FOR_DEBUGGER` conditional switch on in `DemoLanguageServer/Program.cs`. After starting up the Extension Development Host, and activating the language server, you may attach VS Debugger to `dotnet` process and go on debugging.

You may also set the `default` value of `demoLanguageServer.trace.server` to `"messages"` in `package.json` to make language client show more debugging information.
