mech

https://incidentalcomplexity.com/2016/06/10/jan-feb/) Here's a flappy bird game written in that style: https://play.witheve.com/#/examples/flappy.eve It's very declarative, and you have to wrap you brain around the reactivity and working with collections of entities rather than individual objects, so programming this way can be very disorienting for people used to imperative OOP langauges. But the results are that programs are much shorter, and you get the opportunity for really neat tooling like time travel debugging, where you roll the database back to a previous point; "what-if" scenarios, where you ask the system "what would happen if x were y" and you can potentially do that for many values of y; "why not" scenarios, where you ask the system why a value was not generated; value providence, where you trace back how a value was generated... this kind tooling that just doesn't exist with most languages due to how they languages are built to throw away as much information away as possible on each stage of compilation. The kind of tooling I'm describing requires keeping and logging information about your program, and then leveraging it at runtime. Most compilers and runtimes throw away that information as the program goes through the compilation process and as its running. There is a cost to pay in terms of memory and speed, but I think Python shows that interpretation speed is not that much of a barrier to language adoptions. But like I said, that was many years ago and that team has disbanded. I think a lot of what we had in Eve still hasn't reached mainstream programming, although some of what we were researching found its way into Excel eventually. > Loosen Up The Functions... Capabilities... Production-Level Releases... Semi-Dynamic Language... Modular Monoliths I really like where the author's head at, I think we have similar ideas about programming because I've been developing a language called Mech that fits these descriptors to some degree since Eve development was shut down. https://github.com/mech-lang/mech So this language is not supposed to be relational like Eve, but it's more like Matlab + Python + ROS (or Erlang if you want to keep it in the languages domain). I have a short 10 min video about it here: https://www.hytradboi.com/2022/i-tried-rubbing-a-database-on... (brief plug for HYTRADBOI 2025, Jamie also worked on Eve, and if you're interested in the kinds of thing the author is, I'm sure you'll find interesting videos at HYTRADBOI '22 archives and similarly interested people at HYTRADBOI '25), but this video is out of date because the language has changed a lot since then. Mech is really more of a hobby than anything since I'm the only one working on it aside from my students, who I conscript, but if anyone wants to tackle some of these issues with me I'm always looking for collaborators. If you're generally interested in this kind of stuff drop by HYTRADBOI, and there's also the Future Of Coding slack, where likeminded individuals dwell: https://futureofcoding.org. You can also find this community at the LIVE programming workshop which often coincides with SPLASH: https://liveprog.org
