(a) old_top_macros first (with their leading comments),
(b) then non-macro lines,
(c) then new_top_macros. build_top_block_for_no_imports_line Builds the final snippet for the “has_imports_line=false” scenario:
(a) snippet lines first,
(b) then old_top_macros,
(c) then new_top_macros. collect_existing_mod_macro_stems collect_existing_x_macros create_top_block_text Builds a string with one line per TopBlockMacro, preserving each macro’s leading comments
and ensuring each macro ends up on its own line (with no trailing newline). determine_top_block_insertion_offset existing_macros_to_top_block_macros extract_non_macro_lines extract_stem file_has_imports_line filter_new_macros_for_duplicates Removes from new_macros any macro whose stem is already in old_macros. find_earliest_non_macro_item_offset find_last_import_end_before_offset find_top_block_insertion_offset gather_deduplicated_macro_stems gather_leading_comments A helper that walks backward from item.syntax() to pick up line-comments,
similarly to what we do for old macros. If no separate tokens are found,
but the item’s own text starts with //, we parse those lines directly from
full_text as a fallback. gather_old_top_block_macros is_imports_line is_x_macro make_top_block_macro_lines maybe_ensure_newline If there is content in buffer and it does not end with a newline,
push exactly one \n. maybe_push_newline A small helper that ensures if the buffer is non-empty and doesn’t
end with \n, we push exactly one newline. parse_new_macros_with_comments A version of parse_new_macros_with_comments that does NOT do fallback
merging snippet lines into the macro. parse_new_top_block_snippet push_macro_with_comments A small helper for pushing a TopBlockMacro (leading comments + x!{stem}),
ensuring each part ends in exactly one \n if needed. rebuild_librs_with_new_top_block remove_trailing_newlines Removes trailing newlines from the provided buffer string (in-place). snap_offset_to_newline Rounds an offset up to the next newline if it’s in the middle of a line,
without exceeding earliest_offset. splice_top_block_into_source Rebuilds the final text by copying old_text except for old macros,
and inserting the final_top_block at insertion_offset.
This version ensures:
