Library to generate DAP protocol code for gen_dap.
For DAP code generation:
elixir -e 'Mix.install([{:dap_codegen, github: "elixir-lsp/dap_codegen"}]); DAPCodegen.generate(System.argv())' -- --path ./path/for/filesTo update the debugAdapterProtocol.json, you can run the following:
curl --location 'https://microsoft.github.io/debug-adapter-protocol/debugAdapterProtocol.json' | jq . > priv/debugAdapterProtocol.json
A request in the Debug Adapter Protocol (DAP) is a message sent from the client (IDE) to the debug adapter. It typically includes the following features: Type: The type of message, which is always "request". Seq: A sequence number to identify the message. Command: The specific command being requested (e.g., "initialize", "launch"). Arguments: A set of parameters required for the command.

}An event is a notification sent from the debug adapter to the client, indicating a change in state or an occurrence of interest.

},

}A response is sent from the debug adapter back to the client in reply to a request.

},

}An error response indicates that a request could not be processed successfully.
