It's the unix way! (at least partially kidding)
Anyways, I think it is quite common to overwrite an existing file in this case because you update your file. But for default.nix
it is probably not such a great choice.
I could
- Follow your suggestion and require an overwrite flag.
- Look for a string like "Generated by crate2nix" and only overwrite if it is there.
- Change the default to
Cargo.nix
so that it is unlikely that it is used already for something else.
What do you think?
from crate2nix.
I would just add a check if the user doesn’t specify anything explicitely; so:
crate2nix generate -o default.nix
=> overwrite file without a warning
crate2nix generate
=> if default.nix
exists, abort with exists error, if not, just write to it.
