Having issues in sending configuration data to python language server.

[sreetej1998]

Hi, I am trying to send the configuration from the monaco-language-client to the python language server. This is how I tried to do it via the middleware key.

new MonacoLanguageClient({
  name: "Your Name",
  clientOptions: {
    documentSelector: ['python'],
    middleware: {
      workspace: {
        configuration: (params, token, configuration) => {
          return [ {     pylsp: { plugins: { pylint: { enabled: true } } } } ];
        },
      },
    },
  },
  connectionProvider: {
    get: (errorHandler, closeHandler) =>
      Promise.resolve(
        createConnection(connection, errorHandler, closeHandler)
      ),
  },
})

The configuration was not reflected in the editor. I found that the code I wrote in the configuration callback above is not called at all. Despite being sent to the vscode-languageserver-node, and called here.

This Thread might be useful on getting more context.

I am not sure If I am missing anything, would be grateful for any help, Thanks!!

Hello,

I'm not sure how the python language server behave, but there is 2 ways to send configuration to the server:

• When the server asks for it, using the workspace/configuration (it was introduced on the v3.6 of the protocol
• The client can push the workspace/didChangeConfiguration notification to update the config on the server

The first one doesn't require any additional code from the client, while the second requires to set the synchronize.configurationSection on the language client

Also, it requires the configuration features to be enabled on the language client by calling registerConfigurationFeatures on the language client object
