@tamird, I'm experiencing the same. It seems to be that taplo formats the toml file with LF line endings, while the original is with CRLF. Thus, it will always differ in whitespaces.

Have you tried crlf setting? https://taplo.tamasfe.dev/configuration/formatter-options.html

Tried this in a .taplo.toml file:

[formatting]
crlf = true

But still failing. Enabling verbose logging does not give any hints.

After some back and forth, I didn't noticed that taplo converted my files to LF first, thus continued failing. After transforming the .toml files from LF to CRLF, taplo run worked!

Thanks! This is indeed an improvement. Still, I think this should be automatic. For instance, git can be configured to checkout local but commit LF, which may cause pipelines to fail. Same for other CVS.

Would you consider this issue as a feature request to add automatic line-ending detection?
