This is expected and won't be changed. It does not make sense to continue processing if there is nothing to process.

Sorry I haven't given enough informations on the bug, I forget the most important things !
Igir stop/crash when one of the given input is empty.

mkdir empty
mkdir not_empty
touch not_empty/stub.rom
igir copy --dat "*.dat" --input "not_empty" --input "./empty/" --output "./bug_input_output/"

Thanks for your work !

[emmercm]

I'm still tempted to leave the behavior as-is, but I'm curious what your use case for this is?

[Djabal]

I use igir mostly in scripts, so some time there's an empty input folder.
Example : --input "roms_gg" --input "roms_gg_to_import" --output "roms_gg"
But I haven't any roms the first time, so "roms_gg" is empty !

I ask igir to copy all roms it found in the inputs. Not to check if one of the folder is empty. And the folder is not empty, it just have zero roms inside, so why stop ?

Ty !
