New file doesn't run

[Firepup650]

Try this:

@UMARismyname

improved: add/change to start of .replit:

onBoot='''/nix/store/fbi9r30p3lqk96lmw5b1v1bpbj62cr2l-inotify-tools-3.20.11.0/bin/inotifywait -rqme create --include='\..+\.py.[0-9]+~' .|while read f
do d=${f#./}
d=${d% CREATE*}
f=${f#.*.}
f=${f%.*~}
sed -i "/^entrypoint/s|\".*\"|\"$d$f\"|" .replit
done'''

And run kill 1 in Shell.
This will map the entrypoint to the last file you edited through the IDE.
Replace .+\.py on line 1 with the ERE of the files you want to be auto-set as entrypoint.
(I tried an option which checks for you just visiting the file in the editor but I found that that’s impossible. Maybe you can do this with an extension)

Do note that you have to edit the file you want it to run, as it just runs the last edited file.
