tex 0.0.1

Tiny TeX to SVG engine by Andreas Schwenk

tex is a tiny TeX engine that creates SVG images from TeX strings. Currently, only the math environment (e.g. $ f(x) = x^2 $) is supported. Compared to other TeX renderers, this package does NOT rely on JavaScript or any other dependencies.

You will find a playground at https://andreas-schwenk.github.io/tex. Alternatively, open file /docs/index.html in your browser. A local web server is not required.

Warning: this package is under development. Many TeX macros, e.g. \frac{1}{2}, will be supported soon

Features

• Rendering of SVG images from TeX sources
• All data is packed into code. There is no need to load any data at runtime.

Getting started

Add the package into your package's pubspec.yaml file:

dependencies:
  tex: ^0.0.1

Make sure to use the latest version!

Usage

import 'package:tex';

void main() {
  var tex = TeX();
  var svgImageData = tex.tex2svg("f(x,y) = x^2 + y^2");
  if (svgImageData.isEmpty) {
    print('Errors occurred: ${tex.error}');
  } else {
    print(svgImageData);
  }
}

Output SVG:

[img/example.svg]

Additional information

For building the fonts, Python and node must be installed. This is only required for developers of this package.

./build.sh

File meta/glyphs.csv specifies the glyphs.
