Fast wikilink and backlink analysis for Obsidian markdown vaults.

nexis <vault-path>               # full report
nexis <vault-path> --backlinks   # missing backlinks only
nexis <vault-path> --orphans     # orphan notes only
nexis <vault-path> --broken      # broken links only
nexis <vault-path> --format json # machine-readable output

• Missing backlinks — A links to B, but B does not link back to A
• Orphan notes — notes with no incoming or outgoing links
• Broken links — [[Target]] where no Target.md exists in the vault

cargo install nexis

~1s for 10,000+ notes on a warm SSD (rayon parallel parsing).

• Case-insensitive filename matching (APFS-safe)
• Wikilinks inside code blocks are ignored
• [[alias|target]] syntax supported
• JSON output is agent-friendly; human output auto-detects TTY for colour
