Language Servers for AWS

Language servers for integration with IDEs and Editors, which implement the protocol (LSP extensions) defined in the language-server-runtimes repo.

Where things go

• To create a new language capability, see the example hello-world-lsp server and its implementation (using our runtime), and run it.
  • For a more complex (real-world) example, see the Amazon Q language server.
• To create a new protocol feature (LSP extension) for all language servers: contribute to the language-server-runtimes repo.

Monorepo

• app/ - bundled javascript runtime applications for distribution and integration into IDEs
  • aws-lsp-buildspec-runtimes/ - application containing the buildspec language server
  • aws-lsp-cloudformation-runtimes/ - application containing the CloudFormation language server
  • aws-lsp-s3-runtimes/ - application containing the S3 language server
• client/ - Sample LSP integrations for various IDEs. Used to test out the Language Servers
  • jetbrains/ - Minimal JetBrains extension to test the language server
  • visualStudio/ - Minimal Visual Studio extension to test the language server
  • vscode/ - Minimal vscode extension to test the language server
• core/ - contains supporting libraries used by app and server packages
  • aws-lsp-core - core support code
• script - loose scripts used to create npm foo commands in the root folder
• server - packages that contain Language Server implementations
  • aws-lsp-buildspec - Language Server that wraps a JSON Schema for CodeBuild buildspec
  • aws-lsp-cloudformation - Language Server that wraps a JSON Schema for CloudFormation
  • aws-lsp-codewhisperer - Language Server that surfaces CodeWhisperer recommendations.
    • Shows recommendations through completion lists and as ghost text>
  • aws-lsp-s3 - Example language server that provides S3 bucket names as completion items
    • Shows a concept where credentials can be provided from an IDE extension (See vscode and vs client readmes)
