Thanks Allan - I (wrongly) assumed that it was good practice to avoid reopening the connection each time. Things do work fine with your suggested solution then.. now moving on to grammars and scopes :-)
Best, m

I am not sure why you want to reuse the socket.

The server will run and keep listening on port 7099.

Each time you run the command, it will have to create a new connection to the server, but the server can keep state, as it will not terminate between connections/command invocations.

You can use TM_DOCUMENT_UUID or TM_PROJECT_UUID as client ID for the server, so that the server can maintain a “session” per document/project.

Creating a new connection to the server per request is not uncommon or expensive when server is running on localhost.
