# Swift LaTeX
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.
