# LSP Multi Root Example
A language server example that demonstrates how to handle configuration settings in a workspace that uses multi root folders. Since settings in VS Code in this setup are typically scoped to a resource, the example reads the resource settings from the client using the new proposed API getConfiguration. This is analogous to reading settings in a multi-root folder setup directly in the extension host.
The example uses proposed Language Server protocol. So the code demoed here might change when the final version of the configuration and workspace folder protocol is released.
## Compile and Run
- run `npm install` in this folder. This installs all necessary npm modules in both the client and server folder
- open VS Code on this folder.
- Press Ctrl+Shift+B to compile the client and server
- Switch to the Debug viewlet
- Select `Launch Client` from the drop down
- Run the lauch config
- If you want to debug the server as well use the launch configuration `Attach to Server`
- In the [Extension Development Host] instance of VSCode, open a document in 'plain text' language mode.
Enter text content such as `AAA aaa BBB`. The extension will emit diagnostics for all words in all-uppercase.

# README
## This is the README for the "languageprovider-sample"
-------------------
# LSP Multi Root Example
This folder contains a sample VS code extension that demonstrates an extension that runs a language server
A language server example that demonstrates how to handle configuration settings in a workspace that uses multi root folders. Since settings in VS Code in this setup are typically scoped to a resource, the example reads the resource settings from the client using the new proposed API getConfiguration. This is analogous to reading settings in a multi-root folder setup directly in the extension host.
The extension observes all 'plaintext' documents (documents from all editors not associated with a language)
and uses the server to provide validation and completion proposals.
The example uses proposed Language Server protocol. So the code demoed here might change when the final version of the configuration and workspace folder protocol is released.
The code for the extension is in the 'client' folder. It uses the 'vscode-languageclient' node module to launch the language server.
## Compile and Run
The language server is located in the 'server' folder.
- run `npm install` in this folder. This installs all necessary npm modules in both the client and server folder
- open VS Code on this folder.
- Press Ctrl+Shift+B to compile the client and server
- Switch to the Debug viewlet
- Select `Launch Client` from the drop down
- Run the lauch config
- If you want to debug the server as well use the launch configuration `Attach to Server`
- In the [Extension Development Host] instance of VSCode, open a document in 'plain text' language mode.
Enter text content such as `AAA aaa BBB`. The extension will emit diagnostics for all words in all-uppercase.
# How to run locally
* `npm install` to initialize the extension and the server
* `npm run compile` to compile the extension and the server
* open the `lsp-sample` folder in VS Code. In the Debug viewlet, run 'Launch Client' from drop-down to launch the extension and attach to the extension.
* create a file `test.txt`, and type `typescript`. You should see a validation error.
* to debug the server use the 'Attach to Server' launch config.
* set breakpoints in the client or the server.
