do not write formatted string to file at all if overwrite==false

Closes #363

bin/format.jl hasn't been updated in a while, IMO it should be deleted.

Doesn't https://github.com/julia-actions/julia-format/blob/master/workflows/format_check.yml#L34-L42 do the same thing?

Sounds good to me.

Yes but it only works for CI systems that use Github Actions. I think a generic tool that can be called from any CI system would be useful.

ic - well that snippet could be copied over, GHA is not a requirement for it.

That snippet depends on calling format(".", verbose=true) on L32 which modifies the files in-place. My goal here is to be able to call format(".", overwrite=false) to check whether the files are formatted correctly without modifying the files.

Ok that makes sense - the current overwrite functionality is not useful anyway so this looks good.

Can you update the docs here

JuliaFormatter.jl/src/JuliaFormatter.jl

Lines 386 to 388 in acf788c

	If `overwrite` is `true` the file will be reformatted in place, overwriting
	the existing file; if it is `false`, the formatted version of `foo.jl` will
	not be written anywhere.

nvm brain fell asleep lol
