A WASM module-based Server and a full Client API combination.
This project is geared towards other MSFS developers/coders who need a convenient way to remotely access parts of the Simulator which are normally inaccessible via SimConnect, such as some variable types and 'H' events, and running RPN "calculator code" directly on the sim.
The Client API can be utilized natively from C++, or via .NET managed assembly from C#, Python, or other languages.
The system also provides direct access to functions from within the Simulator environment and in many cases could be used as a simpler alternative to SimConnect for basic functionality like reading/setting Simulation Variables or triggering Key Events. SimConnect is still used as the network "transport" layer, but this usage is abstracted into, essentially, an implementation detail.
One of the motivations for this project was seeing multiple MSFS tool authors and casual hackers creating their own WASM modules and protocols just to support their own product or need. There is nothing wrong with this, of course, but for the Sim user it can be a disadvantage on several levels. They may end up running multiple versions of modules which all do essentially the same thing, and it may be confusing which WASM module they need to support which tool, just to name two obvious issues. For the developer, programming the WASM modules comes with its own quirks, too, not to mention the time involved. And regardless of the supposed isolated environment a WASM module is supposed to run in, it's still very easy to take down the whole Simulator with some errant code... ;-)
Since MS/Asobo have been, ahem, "slow" to add further remote access features to SimConnect (or come up with some other method), this project is an attempt at establishing a "standard" or "common" way of doing so. At the least I hope it motivates some kind of standards adoption.
On a more practical note, I am using it with the MSFS Touch Portal Plugin which I'm currently maintaining.
format_calculator_string() using RPN String FormattingSimConnect_MapClientEventToSimEvent(id, "event_name") and SimConnect_TransmitClientEvent(id).. (period) as per SimConnect convention), or derive from the connected Client's name (to ensure uniqueness).SimConnect_TransmitClientEvent_EX1()).
Over in the Releases there are 3 packages provided. (The actual file names have version numbers appended.)
WASimCommander_SDK - All header files, pre-built static and dynamic libs, packaged WASM module, pre-build GUI, reference documentation, and other tools/examples.WASimModule - Just the WASM module component, ready to be dropped into a MSFS Community folder.WASimUI - Just the GUI application, which is very handy in combination with the WASM module for exploring the system.Watch -> Custom -> Releases this repo (button at top) or subscribe to the ATOM feed for release notifications.
Update announcements are also posted on my Discord server's WASimCommander release announcement channel.
The SDK and updates are published on Flightsim.to where one could "subscribe" to release notifications (account required).
There are three basic console-style tests/examples included for C++, C#, and Python in the src/Testing folder. If you like reading code, this is the place to start.
API documentation generated from source comments is published here: https://wasimcommander.max.paperno.us/
A good place to start with the docs is probably the WASimClient page.
The GUI is written in C++ (using Qt library for UI), and while not the simplest example, is a full implementation of almost all the available API features. The main WASimClient interactions all happen in the MainWindow::Private class at the top of the WASimUi.cpp file.
More to come... or Just Read The Source :-)
To check status of the WASM module, enable Developer Mode in MSFS, show the "WASM Debug" window (Options -> WASM) and check if the module shows up in the list in that window. If not, then it's not installed. If it does and any of the text is RED, it is installed but crashed for some reason (let me know!). If the text is green then everything is good on that side.
Also in Dev Mode, check the Console for messages. It may show MSFS errors related to the module, and the module itself logs to the console as well. There should be 2 console log messages from the module when it starts up, the latter showing the version number.
The module also logs to a file, though it's a bit tricky to find. On my edition (from MS store) the "working directory" for the modules is
D:\WpSystem\S-1-5-21-611220451-769921231-644967174-1000\AppData\Local\Packages\Microsoft.FlightSimulator_8wekyb3d8bbwe\LocalState\packages\wasimcommander-module\work
To enable more verbose logging on the module at startup, edit the server_conf.ini file which is found in the module's install folder (Community\wasimcommander-module\modules). There are comments in there indicating the options.
Keep in mind that the server logging level can also be changed remotely at runtime, but of course that only works if you can establish a connection to the module in the first place.
Basically the log is the primary source of information here. By default it logs at the "Info" level to: 1) The current console window, assuming there is one (the host app is started from a console). So if using WASimUI, for example, just start it from a command prompt. 2) A file in whatever current directory it is running in (so, for the UI, that would be the UI's install folder).
Of course if you're using WASimUI, it also provides a full logging interface and you can set all the log levels from there, for both client and server sides.
There should also be a client_conf.ini file alongside whatever is using the Client where initial logging location, levels and network configuration (timeout and SimConnect.cfg index) is set. The config file has comments indicating the available options.
The GitHub repository is the primary source of all these things. You know what to do...
Use the Issues feature for bug reports and concise feature suggestions.
Use Discussions for any other topic.
There is also a Discord support forum on my server, along with release announcement and general chat channels.
Most flight simulator forums seem fairly strict about not using their site to provide product support. So please use GitHub, unless you're absolutely sure no rules would be broken or toes stepped upon otherwise.
