Great idea. I wanted to use pmd to learn some subtle aspects of Java. Tool-assisted learning. It's either operate on existing code and learn the conventions and techniques, or write hundreds of programs in the language. From a maintenance perspective, it's a superpower.
I thought the idea sounded interesting, but it appears to be very narrowly focused on the problem of "I'd like to write something in [German], but I don't know [German] all that well". I'm more interested in the problem of "I'd like to read something in [German]". The "right way" to solve the problem of knowing how to write something in German is, unfortunately, to read several dozen examples of people writing simila…
I'm what people in the Midwest [1] call "good with languages" in that I have learned a host of them to intermediate level, and then run aground on getting to advanced, which I think of as the ability to express yourself colloquially and elegantly on any random topic. An IDE like we're talking about would be a godsend, not least because it would speed things up between ten and a hundred-fold.
Argh, I'm tempted to quit my fucking job and try to make this exist, though I'm not qualified to build it. Maybe someone else will do something comparable -- definitely a "take my money" example :)
[1] I mention being from the Midwest bc, when I was growing up, average small-town people lacked any real access or exposure to (or motivation to acquire) other languages. When I got old enough to travel (also not a thing generally done in my social setting), running into people fluent in 4 languages just by accident of birth, would always make me so jealous :/
