Unusual command line interface about smlfmt HOT 3 CLOSED

Oh, indeed smlfmt < a.sml > b.sml works but using smlfmt > b.sml and pasting doesn't, that's why I thought it doesn't work in general.

It just seemed a bit strange to me, but if you don't think it should be changed this issue can be closed.

smlfmt does accept stdin/stdout:

cat a.sml | smlfmt > b.sml

# or, alternatively:
smlfmt < a.sml > b.sml

One nice thing about the in-place-by-default behavior is that it's consistent between .sml and .mlb input. And, in-place updates seem like they would be the common case for a tool like smlfmt. (This is certainly the case for me, but not sure about other people.)

Honestly I don't have a super strong preference either way, but I'm a bit wary of changing things.

Okay sounds good! For now, I think I'd prefer not to change it, just in case someone is relying on the existing interface.

I'll keep in it mind though; if we need to make a backwards-incompatible change in the future anyway, then perhaps this can be changed then too.
