Preserve multiline for line ending with \

[ezh]

Hey. I have the next yaml.

What is the best way to preserve multiline for the regex value?

I cannot use > scan_folded_as_literal because there will be spaces between elements.

Hi @ezh thanks for opening an issue.

Do you have retain_line_breaks set with this example? See the docs to see how to set that.

[ezh]

$ cat $HOME/.config/yamlfmt/.yamlfmt
formatter:
  type: basic
  retain_line_breaks: true
  scan_folded_as_literal: true

[ezh]

@braydonk You can reproduce it quickly. Copy'n'paste the above YAML to test.yml and run
yamlfmt -conf ~/.config/yamlfmt/.yamlfmt test.yml with retain_line_breaks.
