Ramses Daemon API

The Ramses Daemon is a local server used by the Ramses Add-ons to get and set data to the client (which in turn communicates with the Ramses Server to store the shared data) and the whole system.

The Ramses Daemon is automatically run by the Ramses client, the native application which is the heart of Ramses.

Connecting to the Daemon

Add-ons can communicate with the Daemon through a standard TCP Socket. The Daemon listens on port 181851 by default (but this can be adjusted in the Ramses Client settings), and is automatically started by the Ramses client. It is terminated when the client quits.

Most of Ramses data can only be accessed if a user is logged-in in the Ramses Client, thus before communicating with the Daemon, a Ramses Add-on must check if the Client (and its Daemon) is running (or start it), and if a user is logged-in.

The initial connection to the Daemon usually follows these steps:

  1. Check if the Daemon is running by sending the ping query.
    1. If the Daemon replies, connection is ready
    2. Else, try to start the client and ping again.
  2. Check the version of the Daemon which is part of the reply to the ping.
  3. Check if the user is logged-in; if not, show an alert and raise the Ramses Client window.

Communicating with the Daemon


Add-ons can post queries which use the form of the attributes part of a standard URL query; they are a single-line string of key=value pairs (the value may be optional) seperated by the & character. They should be encoded in UTF-8, and special characters should use a standard URL percent-encoding. There’s no need to enclose strings in quotes.

Example queries:


setCurrentProject&shortName=PROJ&name=The Project


The Daemon replies with a JSON object (encoded in UTF-8) which contains the following attributes:


Replies are a single-line string, but they’re prettyfied in this documentation for the sake of readabiliy

Example Replies:

    "accepted": true,
    "query": "ping",
    "success": true,
    "message": "Hi, this is the Ramses Daemon.",
    "content": {
        "version": "0.0.1",
        "ramses": "Ramses",
        "userName": "John Doe",
        "userShortName": "J.Doe",
        "logged-in": true
    "accepted": true,
    "query": "setCurrentProject",
    "success": true,
    "message": "Current project set to: The Project.",
    "content": {
        "name": "The Project",
        "shortName": "PROJ",
        "path": "/home/user/Ramses/PROJECTS/The Project",
        "uuid": "12456abc"
