The links-resolve scanner skipped fenced blocks but read inside inline code spans, so a pattern like [2-9](\.\d+) in backticks was reported as a link to a missing file. Each line now has its code spans removed before link extraction, delimited per CommonMark (a run of N backticks closes at the next run of exactly N; an unmatched run stays literal). Adds a CLI test (quoted text passes, the same text unquoted is still checked) and a note in REFERENCE.md.

Closes #287

Summary by CodeRabbit

  • Bug Fixes
    • Links inside Markdown inline code spans are no longer reported as broken links. Backtick spans of matching lengths are recognized; unmatched backticks remain literal.
  • Documentation
    • Clarified that fenced code blocks and inline code spans are excluded from broken-link checks.

📝 Walkthrough

Walkthrough

The Markdown link scanner now skips matched inline code spans before checking reference definitions and inline links. The reference documentation describes this behavior, and a CLI test checks both ignored links inside code spans and reported links outside them.

Changes

Inline code span filtering

Layer / File(s) Summary
Filter inline code before link matching
src/scan.rs, tests/scan_cli.rs, docs/REFERENCE.md
link_targets removes matched inline code spans before applying reference and inline link patterns. Matching requires opening and closing backtick runs of equal length; unmatched runs remain literal. The CLI test checks links inside and outside code spans. The documentation describes the exclusion.

Track code spans across non-fenced lines.

When a valid code span opens on one line and closes after [a](missing.md) on another, the per-line filter leaves the link visible. links-resolve can then report it as a missing target and fail the scan. Match exact-width backtick runs across non-fenced lines before extracting links, while preserving the original line numbers. This is a narrow false-positive case, not a major-impact issue.

Do not treat an escaped backtick as a code-span opener.

When a backtick is preceded by an odd number of backslashes, preserve the escaped backtick and continue scanning. Otherwise, r"\a"`` can lose a` before the link check sees it. This is a narrow missed-link-check case, so classify it as minor.

         let open = rest + offset;

Keep a separator when removing an inline code span.

For [a]code(gone.md), without_code_spans joins the surrounding text into [a](gone.md). link_targets then matches gone.md. If that target does not exist relative to the document, the links-resolve scanner reports it as missing.

…ion in backticks such as [2-9](\.\d+) is no longer reported as a missing file

CommonMark gives a code span precedence over link syntax. The scanner
skipped fenced blocks only, so a generated page printing a pattern in
backticks was refused, and the only remedy was to exclude the file and
lose its real links from the check. Each line now has its code spans
removed before link extraction, delimited as CommonMark does: a run of
N backticks closes at the next run of exactly N, and an unmatched run
stays literal.

Closes #287
