# nexis
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
```
## What it reports
- **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
## Install
```bash
cargo install nexis
```
## Performance
~1s for 10,000+ notes on a warm SSD (rayon parallel parsing).
## Notes
- 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
