setup-lsp-dev.sh helps you to setup an experimentation environment for the Language Server Protocol. The LSP Client and the LSP server are built using the VS Code LSP SDK for node.js and are bundled as a VS Code extension. The SDK comprises 5 different npm modules. To experiment with protocol modifications it is helpful to have these npm modules in source.

Execute setup-lsp-dev.sh from the folder in which you want the environment to be set up. The script creates a lsp-dev folder with the environment.

insiders-lsp-dev.sh opens two VS Code insider windows. One for the LSP client and server, and one for the SDK.
