Blazingly fast Rust library for parsing and analyzing [Obsidian](https://obsidian.md) vaults.
## Features
- ⚡ **High Performance**: Parses 1000+ notes in under 3ms
- 🧠 **Knowledge Graphs**: Built-in integration with [`petgraph`](https://docs.rs/petgraph/latest/petgraph) for advanced analysis
- 🧩 **Flexible API**: Supports both in-memory and on-disk note representations
- 🔍 **Frontmatter Parsing**: Extract YAML properties with [`serde`](https://docs.rs/serde/latest/serde) compatibility
- 🌐 **Link Analysis**: Identify connections between notes
- 👾 **WebAssembly Support**: Add `obsidian-parser` to your Obsidian plugins
## Quick Start
Add to `Cargo.toml`:
```toml
[dependencies]
obsidian-parser = "0.9"
```
### Basic Usage
* Basic Parsing
```rust
use obsidian_parser::prelude::*;
use serde::Deserialize;
let note_hashmap = NoteInMemory::from_file_default("note.md").unwrap();
println!("Content: {}", note_hashmap.content().unwrap());
println!("Properties: {:#?}", note_hashmap.properties().unwrap().unwrap());
#[derive(Clone, Deserialize)]
struct NoteProperties {
created: String,
tags: Vec<String>,
priority: u8,
}
let note_with_serde: NoteInMemory<NoteProperties> = NoteInMemory::from_file("note.md").unwrap();
```
* Vault Analysis
```rust
use obsidian_parser::prelude::*;
let options = VaultOptions::new("/path/to/vault");
let vault: VaultInMemory = VaultBuilder::new(&options)
.into_iter()
.filter_map(Result::ok)
.build_vault(&options)
.unwrap();
if !vault.have_duplicates_notes_by_name() {
eprintln!("Duplicate note names detected!");
}
for note in vault.notes() {
println!("Note: {:?}", note);
}
```
* Graph Analysis (requires [`petgraph`](https://docs.rs/petgraph/latest/petgraph) feature)
```rust
#[cfg(feature = "petgraph")]
{
use obsidian_parser::prelude::*;
use petgraph::dot::{Dot, Config};
let options = VaultOptions::new("/path/to/vault");
let vault: VaultInMemory = VaultBuilder::new(&options)
.into_iter()
.filter_map(Result::ok)
.build_vault(&options)
.unwrap();
let graph = vault.get_digraph().unwrap();
println!("{:?}", Dot::with_config(&graph, &[Config::EdgeNoLabel]));
let most_connected = graph.node_indices()
.max_by_key(|n| graph.edges(*n).count())
.unwrap();
println!("Knowledge hub: {:?}", graph[most_connected]);
}
```
## Example: Analyze Knowledge Connectivity
Included example `analyzer` calculates connected components in your Obsidian vault's knowledge graph:
```bash
cargo run --example analyzer --release --features="petgraph rayon" -- --path="Path to Obsidian vault"
```
