Does anyone have a good non-gaming use case for Haxe? It feels very nice to have multiple compilation targets and the language is great, but I never found an excuse to use it.
The creator of http://haxeui.org/ makes a lot of (closed) projects for the health sector.
I personally like to use to make some wxwidgets utilities apps with it. (And being able the html5 js target and android/ios (with openfl) target.
Internal frameworks seem to be a popular scenario for Haxe. Something where you are the vendor for the platform abstraction, not the consumer. Or you have a codebase that needs some incremental migration between targets.
This is stuff that is incredibly hard to justify as a hobby project but definitely in the realm of what Haxe does well.
same here, it's a forever top of mind but never to be practically used. The thought of having one language but can dish out frontend in JS, backend in python, jobs in C has been a dream of mine.
https://github.com/c-blake/cron might interest you. This uses "job" from GP in the sense of "cron jobs", although GP meant something much more broad by "jobs in C". ;-)
The key idea is portable to any prog.lang. you might like, although many will not be as run-time efficient as Nim, C, etc. and many may not be as safe as Nim.
