# wmap-parser-rust

A parser for `wmap` formatted Wardley Map files built in rust.

## Features

* No dependencies.
* Free software.
* Reasonably fast.

## Installation

Add it to your project with cargo add

```bash
cargo add wmap-parser
```

## Usage

```rust
use wmap_parser::parse;

fn main() {
    let wmap_source = r#"
[I] 0.25
[II] 0.5
[III] 0.75
[IV] 1.0

Tea (0.9, 0.5) [Circle]
Cup (0.8, 0.4)
Hot Water (0.6, 0.2)

Tea -> Cup
Cup -> Hot Water

[Note] (0.5, 0.5) Supply chain for tea
[Group] Tea, Cup
[Inertia] Cup
[Evolution] Tea + 0.1
"#;

    let map = parse(wmap_source);

    println!("{:?}", map.components);
    // [
    //   Component { label: "Tea", coordinates: (0.9, 0.5), shape: Circle },
    //   Component { label: "Cup", coordinates: (0.8, 0.4), shape: Circle },
    //   ...
    // ]

    println!("{:?}", map.dependencies);
    // [
    //   Dependency { from: "Tea", to: "Cup", is_directed: true },
    //   ...
    // ]
}
```

## API

### `parse(source: &str) -> Map`

Parses a wmap formatted string and returns a Map object.

**Parameters:**

- `source` (&str): The wmap source code to parse

**Returns:**

- `Map`: A Map struct containing the parsed components, dependencies, notes,
    stages, groups, inertias, and evolutions

## Format Specification

See [The map website](https://map.tranquil.systems) for more information on the
format.

## Reasonably Fast

Benchmarked on an M1 Pro mac. A map with around 120 entities parses in 7µs.
While a larger map with slightly under 2000 entities does so in 215µs.

You can run the benchmarks by using:

```bash
make benchmark
```

## Development

This project uses a Makefile to run all commands. This is to keep the
commands uniform with the other wmap-parser projects.

### Running Tests

```bash
make test
```

Or to see coverage

```bash
make coverage
```
