I have tried couple of times to share my PS source files like this:
https://try.purescript.org?github=/jarmol/elmSunPosCalc/blob/master/pures/src/test-julian.purs
and this:
https://try.purescript.org/?github=jarmol/elmSunPosCalc/blob/master/pures/src/test-julian.purs
but I got only errors 404.
However, it works Ok if shared with /?code :
https://try.purescript.org/?code=LYewJgrgNgpgBAKWgSwIY......
Here are my codes which I tried to share from repo.
