# wmap-parser-swift
A parser for `wmap` formatted Wardley Map files built in Swift.
## Features
* No dependencies.
* Free software.
* Reasonably fast.
## Installation
Add it to your project using Swift Package Manager by adding the following to your `Package.swift`:
```swift
dependencies: [
.package(url: "https://git.sr.ht/~rbdr/wmap-parser-swift", from: "1.0.0")
]
```
Or add it directly in Xcode using File > Add Packages...
## Usage
```swift
import WmapParser
let wmapSource = """
[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(wmapSource)
print(map.components)
// [
// Component(label: "Tea", coordinates: (0.9, 0.5), shape: .circle),
// Component(label: "Cup", coordinates: (0.8, 0.4), shape: .circle),
// ...
// ]
print(map.dependencies)
// [
// Dependency(from: "Tea", to: "Cup", isDirected: true),
// ...
// ]
```
## API
### `parse(_ source: String) -> Map`
Parses a wmap formatted string and returns a Map object.
**Parameters:**
- `source` (String): 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 14µs.
While a larger map with slightly under 2000 entities does so in 230µs.
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
```
