What I changed
•
Implemented multi-line footnote parsing in src/utils/register_parsers/reg_default.ts.
•
Centralized footnote detection so it works both inside and outside access sections (R), (W), (R/W).
•
Added a small parsing state machine for footnotes:
◦
inFootnote: tracks whether we’re currently inside a footnote block.
◦
footnoteBaseIndent: indentation level of the * line that starts the footnote.
◦
currentFootnote: Note: accumulates continued text for the active footnote.
•
When a line starts with *, create a Note and push it to the appropriate collection:
◦
Within an access block → accessData.notes.
◦
Outside an access block → reg.notes.
•
Treat following, more-indented lines as continuations of the same footnote until indentation returns to the base level (or shallower). Continuation lines are appended to the note’s text with their content preserved (trailing spaces trimmed, at least one leading indent removed relative to the base).
•
Ensured any active footnote is closed if EOF is reached.
•
Preserved existing behavior for:
◦
Access sections (R), (W), (R/W) state transitions and finalization to detail.
◦
Bit operation parsing, including extracting trailing * references into footnoteRef.
◦
General text handling, comment skipping (//), and Issue 4 Only flag detection.
•
Minor cleanup: safe optional chaining when computing spaces_at_start.
Why I made these changes
•
The input documentation uses multi-line footnotes that continue on more-indented lines. Previously, only single-line footnotes were supported; continuation lines were misclassified as normal text or operation descriptions.
•
Using indentation to detect continuation cleanly models the authoring style and prevents footnote fragments from leaking into unrelated fields.
•
Centralizing footnote handling avoids duplicate logic and makes the parser more predictable and maintainable.
Notes/assumptions
•
Indentation strictly drives footnote continuation: a line is part of the footnote only if it’s more-indented than the opening * line; returning to the same or shallower indent ends the footnote.
•
Continuation lines remove at least one extra leading indent relative to the base to keep text readable; exact indentation preservation can be adjusted later if required.
•
Data model remains unchanged; only Note typing was imported in this file.
Impact and compatibility
•
No breaking API changes.
•
Behavior is unchanged for non-footnote content.
•
Other parsers unchanged.
Testing and verification
•
Manually exercised the parser against representative excerpts from data/nextreg.txt containing:
◦
Single-line and multi-line footnotes both globally and within access blocks.
◦
Footnote continuation lines with varying indentation.
◦
Bit operation lines with trailing * references.
•
Verified that:
◦
Footnotes aggregate expected text lines.
◦
Access block boundaries and operation parsing remain intact.
◦
Dangling footnotes at EOF are closed without error.
Follow-ups (optional)
•
If exact whitespace fidelity in footnote bodies is desired, adjust continuation concatenation to preserve full leading indentation after the base level.
•
Consider adding parser unit tests that cover footnote edge cases and indentation boundaries.
