i just did a little poc of how to spawn another program from a roc app, so i needed a little test case. i don't know why, but for some rease a program building itself gives me some goosebumbs. ^^
Ayaz Hafiz (Apr 13 2023 at 19:43):very cool! the first bootstrapping Roc program!
Brendan Hansknecht (Apr 13 2023 at 22:45):Haha, love it
Rene Mailaender (Apr 14 2023 at 21:05):Well i couldn't resist:

and yes , it really gets into an infinite loop. so i had to ctrl^c
funny though. when building first and then running the executable, it crashes:

Richard Feldman (Apr 15 2023 at 01:20):could we give a nicer error for that?

makes sense i gues. but why does it not happen when i roc run ... ?
Brendan Hansknecht (Apr 15 2023 at 15:25):That runs from memory and just happens to also flush to disk rather than flushing to disks and then running from disk
Rene Mailaender (Apr 15 2023 at 15:25):makes sense. thx
