ZigTeX


ZigTeX is a wrapper around [MicroTeX](https://github.com/NanoMichael/MicroTeX/tree/openmath) with a custom SVG renderer. ZigTeX principally gives you one function, which takes some LaTeX code and spits out an SVG:

```zig

const std = @import("std");

const ztex = @import("zigtex");

pub fn main() !void {

    var gpa = std.heap.GeneralPurposeAllocator(.{}){};

    defer _ = gpa.deinit();

    const allocator = gpa.allocator();

    var render = try ztex.TexSvgRender.init(allocator, .{});

    defer render.deinit();

    const tex =

        \\\begin{equation}

        \\    \hat{F}(\nu) = \int_{-\infty}^\infty e^{-i 2\pi t \nu} f(t) \text{d}t

        \\\end{equation}

    ;

    const output = try render.parseRender(allocator, tex, .{});

    defer allocator.free(output);

    var f = try std.fs.cwd().createFile("example.svg", .{});

    defer f.close();

    try f.writeAll(output);

}

```

This produces the title image on a transparent background.

## Usage

To use in your Zig project, add this project as a dependency

```bash

zig fetch --save https://github.com/fjebaker/zigtex/archive/main.tar.gz

```

Then modify your `build.zig` in the usual way:

```zig

const zigtex_dep = b.dependency(

    "zigtex",

    .{.optimize = optimize, .target = target},

);

// ...

exe.root_module.addImport("zigtex", zigtex_dep.module("zigtex"));

```
