🐛Mixed EOL files created on WinOS

[rivy]

I'm running into files created by bindgen for WinOS platforms that have mixed line endings (both CRLF and LF).
For example, bindings/i686-pc-windows-msvc.rs is a mixed EOL file with \r\n\n ending the starting comment.

It looks like this code is the cause...

rust-bindgen/bindgen/lib.rs

Lines 925 to 934 in d71972a

	const NL: &str = if cfg!(windows) { "\r\n" } else { "\n" };
	if !self.options.disable_header_comment {
	let version =
	option_env!("CARGO_PKG_VERSION").unwrap_or("(unknown version)");
	writeln!(
	writer,
	"/* automatically generated by rust-bindgen {version} */{NL}",
	)?;
	}

NL is set per-platform, but writeln! always ends with LF, no matter the platform (see https://doc.rust-lang.org/std/macro.write.html).

I think that the code you likely want for the write would be:

write!( 
     writer, 
     "/* automatically generated by rust-bindgen {version} */{NL}{NL}", 
)?;
