# Swift LaTeX

![LaTeX_project_logo_bird Medium](https://user-images.githubusercontent.com/91354917/196522108-766c7286-d726-4bca-bbfe-b8ba64774175.png)

Display LaTeX using [MathJax](https://github.com/mathjax/MathJax). The package also provides a custom LaTeX DSL, which enables you write LaTeX the way you write SwiftUI Views.

## LaTeX with SwiftUI

A View called `LaTeXView` is avaiable to display formulas in LaTeX.

```swift
import LaTeX
import SwiftUI

struct ContentView: View {
    
    var body: some View {
        LaTeXView(formula: "\\pi")
    }
    
}
```

---
As a javascript package was used to render LaTeX, the Outgoing network Connections needs to be enabled in Project Sandbox.

## LaTeX DSL

This part was designed with the goal of writing LaTeX the way you write SwiftUI.

$$ \sum\_{x = 1}^{10} {{{\color{3a81f6} x}}^2} $$

```swift
let formula = LaTeXBuilder.build {
    Sum("x", from: 1, to: 10) { x in
        x
            .colored(.blue)
            .squared()
    }
}
```

Note that the `Components` are translated to LaTeX only when `.latexExpression` is called.
```swift
print(formula)
// RangedLargeOperator<...>(...)

print(formula.latexExpression)
// \sum_{x = 1}^{10} {{{\color{3a81f6} x}}^2}

print(formula.evaluated())
// numeric(385.0)
```

$$ {{\nabla\times{\overrightarrow{\mathbf{B}}}}-{{\color{3a81f6} \frac{1}{C}}} \frac{\delta \overrightarrow{\mathbf{E}}}{\delta t}}={4 \pi \rho} $$

```swift
Equals {
    Subtraction {
        Multiplication {
            nabla
        } by: {
            "B".font(.mathbf).overRightArrowed()
        }
    } by: {
        Fraction(1, "C")
            .colored(.blue)
    }
    
    Fraction {
        delta
        "E".font(.mathbf).overRightArrowed()
    } denominator: {
        delta
        "t"
    }
} with: {
    4
    pi
    rho
}
```

$$ \int\_{-N}^N {e^x \\, \mathrm{d}x} $$

```swift
Integral("x", from: "-N", to: "N") { variable in
    Power {
        "e"
    } with: {
        variable
    }
}
```

$$ {R\_\theta}={\begin{bmatrix}\cos\theta & -\sin\theta \\\\ \sin\theta & \cos\theta\end{bmatrix}} $$

```swift
Equals {
    Subscript {
        "R"
    } with: {
        theta
    }
} with: {
    LaTeXMatrix {
        [
            [cos(theta), -sin(theta)],
            [sin(theta),  cos(theta)]
        ]
    }
}
```

## Using Swift LaTeX

If you are working on a Swift Package, use
```swift
// inside Package.swift
dependencies: [
    .package(url: "https://github.com/Vaida12345/Swift-LaTeX.git")
],
```
Otherwise, use the project link to find this package in Xcode.
