Description

Having a multiline strin causes the formatter to insert blank lines above an below each line on each an every file format.

Example

Given the following example:

let s = `
  1
  2
  3
`

On the first format call, this becomes:

let s = `

  1
  
  2
  
  3
  
`

On the second:

let s = `


  1



  2



  3

...etc

Version

• OS: Windows 11
• Rescript: 11.0.0-rc.7

Additional Context

As I was writing this issue, I noticed this does not happen with npx rescript format, only when issuing a format call from the IDE, VS Code in my case with the official rescript plugin.

This has to do with the editor line ending settings. Try changing that.

@zth Switching from CRLF to LF did seem to fix it, although this probably should still be marked as a bug?
