--diff
is disabled in #311 (IIUC becausetokio
does not compile on wasm at that time?) But now I think it does compile, so I propose adding--diff
back.For reference if needed: my use case
My use case is in the CI of a node project, which needs
--diff
so that people can know exactly which lines to change. Without this feature in wasm I have to download a separate taplo binary (it's fine but slighly more complex), instead of putting it in dev dependencies and install along with all other packages.
