CogniCrypt for Visual Studio Code

A minimal Visual Studio Code extension hosting the CogniCrypt language server. Based on the official lsp-sample project discussed in the Language Server Extension Guide.

Getting Started

Language Server Setup

There's two ways for the VS Code extension (the language client) and the CogniCrypt language server to communicate:

• stdio: VS Code starts a new instance of the language server and communicates over standard IO.
• socket: VS Code connects to an already running language server via a socket on port 5007. This is useful for debugging the language server.

The required setup depends on your choice of transport mode:

• stdio: The extension expects a JAR file (crypto-lsp-demo-0.0.1-SNAPSHOT.jar) in the "resources" folder, so you need to run mvn package -DskipTests on the language server to obtain the JAR and copy it to the "resources" folder.
• socket: Run the language server with the -socket argument, either from the command line or your favorite IDE.

Language Client Setup

• Run npm install in the repository's root folder. This installs all necessary npm modules in the "client" folder.
• Open VS Code on the repository's root folder.
• Press Ctrl+Shift+B to compile the client.
• From the Debug viewlet, run the "Launch Client" config. This launches a new VS Code instance "[Extension Development Host]" with the CogniCrypt extension enabled.
• Open a Java file and wait for CogniCrypt to report something.

Under Settings > Extensions > CogniCrypt you can switch between the two transport modes stdio and socket.
