From 2285e85a31da91e8576f0d28494facc49e989d79 Mon Sep 17 00:00:00 2001 From: Ralf Anton Beier Date: Thu, 2 Apr 2026 20:00:49 -0400 Subject: [PATCH 1/2] feat(doc): byte-offset span tracking for [[ID]] refs and headings (Phase 4) DocReference gains col, byte_offset, len fields for precise positioning. Section gains heading_line and heading_byte_offset. validate_documents() now provides column info in diagnostics. 6 new tests: byte offset roundtrip, column not at start, multiple refs on one line, multiline offsets, section heading spans. --- rivet-core/src/document.rs | 135 +++++++++++++++++++++++++++++++++++-- rivet-core/src/validate.rs | 2 +- 2 files changed, 131 insertions(+), 6 deletions(-) diff --git a/rivet-core/src/document.rs b/rivet-core/src/document.rs index 8fb7121..af35fc9 100644 --- a/rivet-core/src/document.rs +++ b/rivet-core/src/document.rs @@ -103,6 +103,10 @@ pub struct Section { pub title: String, /// Artifact IDs referenced within this section (until the next heading). pub artifact_ids: Vec, + /// 1-based line number of the heading in the document body. + pub heading_line: usize, + /// Absolute byte offset of the heading line in the document body. + pub heading_byte_offset: usize, } /// A single `[[ID]]` reference found in the document body. @@ -112,6 +116,12 @@ pub struct DocReference { pub artifact_id: String, /// Line number (1-based) where the reference appears. pub line: usize, + /// 0-based byte offset of `[[` within its line. + pub col: usize, + /// Absolute byte offset of `[[` in the document body. + pub byte_offset: usize, + /// Length in bytes including the `[[` and `]]` delimiters. + pub len: usize, } // --------------------------------------------------------------------------- @@ -237,24 +247,32 @@ fn split_frontmatter(content: &str) -> Result<(String, String), Error> { /// Extract all `[[ID]]` references from the markdown body. fn extract_references(body: &str) -> Vec { let mut refs = Vec::new(); + let mut line_start_offset: usize = 0; for (line_idx, line) in body.lines().enumerate() { - let mut rest = line; - while let Some(start) = rest.find("[[") { - let after = &rest[start + 2..]; + let mut search_offset: usize = 0; + while let Some(rel) = line[search_offset..].find("[[") { + let start = search_offset + rel; + let after = &line[start + 2..]; if let Some(end) = after.find("]]") { let id = after[..end].trim(); if !id.is_empty() { + let len = 2 + end + 2; // [[ + content + ]] refs.push(DocReference { artifact_id: id.to_string(), line: line_idx + 1, + col: start, + byte_offset: line_start_offset + start, + len, }); } - rest = &after[end + 2..]; + search_offset = start + 2 + end + 2; } else { break; } } + // +1 for the '\n' separator (or end of string) + line_start_offset += line.len() + 1; } refs @@ -264,8 +282,9 @@ fn extract_references(body: &str) -> Vec { fn extract_sections(body: &str) -> Vec
