The article discusses the importance of 'doc comments' in Go, which must precede top-level declarations without any line breaks. It highlights that every exported entity requires a doc comment. The author describes their approach to modifying the comment removal process by implementing Go-style comments using regex patterns that accommodate the syntax's unique characteristics. A test case is created to ensure that the code correctly preserves doc comments while stripping away non-doc comments, focusing on implementing negative lookaheads in regex for this purpose.
"Doc comments are critical in Go as they provide necessary documentation for exported names. Every exported (capitalized) name should have a corresponding doc comment for clarity and usability."
"Implementing Go-style comments requires a careful selection of regex patterns to ensure that doc comments are preserved while non-doc comments are removed effectively."
