Request for help. My product manager has requested to preserve line breaks in SQL expressions, but the content I obtained through parser.sqlify no longer contains any line breaks.

Original requirement: The product manager wants users to input custom expressions, and the frontend performs formatting validation, field validation, and provides shortcuts for syntax input. I have successfully addressed these requirements using this library. For example, when performing field validation, I return the fields in the form of [xx] and later dynamically replace these [xx] with <span title="xx does not exist">xx</span> using regular expressions. Of course, I have taken into account the risk of HTML injection.

Now the problem is, when users input line breaks, for example, some users may input very long expressions and expect to preserve some basic formatting. However, when using sqlify, the line breaks and content indentation are lost. Can you please advise on how to proceed?"
