Function createCoreTransform

Create a core transform.

Caution: This transform mutates the input AST.

This transform is intended to be used as a common pre-processing step. Other, more configurable transforms can be applied afterward, where they can leverage the consistent output from this transform.

This transform handles:

• Line splitting — Each line's content is wrapped with <div class="imp-l">
• Trimming/collapsing empty lines
• Trimming trailing whitespace from lines
• Annotation parsing
• Section parsing
• Whitespace wrapping — Spaces are wrapped with <span class="imp-s">, and tabs are wrapped with <span class="imp-t">
• Redaction of sensitive information - Redactions are wrapped with <span class="imp-rd" data-imp-rd="<type>">
