I would argue that Forth doesn't have any grammar to speak of. It's just a string of words strewn together.
Would stream-of-consciousness language* be an appropriate name?

Extensible languages, bell-bottoms and polka dots were a thing in the 60-es. They didn't age too well 
For your reading pleasure check this SPG language.

There are all kinds of ways to skin that cat though, and the 1960s you had some severe limitations in terms of compilers due to the limited RAM and speed of computers in that era.

I say, stop bloating the languages. Do the basics well, and use libraries for everything else. If you keep doing the same thing repeatedly, libraries are well suited for that purpose - do it once, wrap it up, and re-use it.
Otherwise you're just extending the language to suit your own needs, and everybody's needs are different - and that's what leads to bloat. Not only that, but you end up spending more time tinkering with the language extensions than the actual code and business logic. And not everybody can work at that level.

Seems like C# got bloated without really doing any of this.
is it really such a bad idea for example to do
public component Foo { // implements IComponent, IPropertyNotify, IDisposable etc
public Bar { get; set; } // generates OnBarChanged/BarChanged, etc
};
and save all of that code? You can't really make that into a library. At best you're using a C# Source Generator and some sort of input document.
or even
public entity Contact { // implements all of the data bound stuff
};
And if that's too much, what about simply the ability to extend the grammar via Source Generators so you could create or install these (as nuget packages) to extend the language as the project requires?

What you describe is exactly why I think MSFT is on point with the "targetted models" approach to AI-assist in code.

Now that's interesting. It occurred to me that AI might be able to insert itself here with some benefit to the developer but I wouldn't know enough about it - having not even used CoPilot for example - to really say so this is news to me.

The product is expensive, but I haven't seen anything to compete with it, and I need the ability to sniff MODBUS commands and responses on a RS-485 bus, interpret them correctly, and save them to a log. This item looks like it will do the job, but it needs to be connected to a PC to perform. I'm thinking I can build or buy a single board computer small enough to be deployed in the field inside a weather-proof box for a week or two to search for missing commands or spurious ones. It would be very helpful to hear from previous users, though, before I embark on this course.

I haven't, but they do have a forum which might be a good place to duplicate this request?

Interesting, but as with most MODBUS products, it wants to be either a Master or a Slave. I just need to log everything on the bus.

Nice system! If I was working on developing devices it would be very helpful. But I need something I can hang in a cabinet in the field and let it run. I have a solar array (840 kW) connected to a battery (1 MW / 2 MWh), both controlled by a Site Controller. There have been some anomalous events over the past few months, and I suspect communications issues. With 14 inverters, three diesel generators and one big battery, it's hard to isolate which unit is having problems, especially when I can't get confirmation that the controller even sent the proper commands! Seriously, who would build a system controller that has no logging capability? I expected better of Tesla!

You *could* in theory make one of these. I'm not sure what it costs, but if it's expensive and you're not sure you could produce one yourself with some work.
I made something similar, but it was simply for a basic serial UART, not RS-485.

You could adapt code like that using code like this:
GitHub - zivillian/esp32-modbus-gateway: ESP32 Modbus RTU/TCP Gateway[^]
Just a thought, even though it may not be realistic for you. I'd do it, but then I'm a bit crazy.

I was thinking something like passing it through a pi kind of akin to a proxy. Just echo the traffic out the other side.
A simple device to do only that might have market because splitting it means you could have the traffic sent to logging and the device, or maybe to a 'real device' and also a device under development/testing.
They build something like this in a pizza box rack mount style, though I don't recall what it was called. PC feeds all serial to it and it then feeds the serial wherever you configure/connect it.

I would use a realtime MCU rather than a Pi for that. I just don't trust what is essentially a tiny PC to have the regular latency to keep a clean, uninterrupted signal. It probably will, I'm just paranoid. Part of it too is I think an RPI would be overkill when a cheapo ESP32 could easily handle it.

Yeah, it'd definitely fail from what I get about all this. But temp diagnostic tool vs production component maybe?
Sounds like it'd be just plug it in and capture the broadcast packets and throw them on disk. At least that way failure just means losing the logging you had it doing.

There is no need to pass data through it at all. All that does is unnecessarily add another potential point of failure. This is RS-485 which is inherently multi-drop so it would be much better to have a listen-only device.

Ahh... broadcast to all on subnet... I hear.

If I had the time, I'd do it, too! There's never enough hours in the day...
