2. biome errors :

Expected result

Biome proceed :) and probably skip the endofline config?

We don't support that option https://biomejs.dev/reference/configuration/#formatterlineending, and it's voluntary. I suggest you to open a discussion, or look for opened discussions around this topic

my bad, i looked for endOfLine in GH, and nothing came back ...
Would you be open to "just" make something to not define the endOfLine or something? so that the migration can proceed anyway ?

[ematipico]

Sorry, I didn't understand what you're suggesting 😅

[eMerzh]

Oupsi ..
i'll try again
currently, the migrate command fails because of this option.

I totally get that you don't want to support "auto" in biome.
But i "suggest", to either ignore the "auto" value, or convert it forcibly to the preferred option.
(i would say we shouldn't leave the ending as default)

That way, the migration can proceed instead of erroring

clearer?

[eMerzh]

I'll try a pr or smth to discuss it
