latex

latex is a package holding Go tools for LaTeX.

latex is supposed to provide features akin to MathJax or matplotlib's TeX capabilities. ie: it is supposed to be able to draw mathematical equations, in pure-Go.

latex is NOT SUPPOSED to be a complete typesetting system like LaTeX or TeX.

For this, please take look at:

• Star-TeX
• Star-TeX (git repo)

Eventually, go-latex/latex might just use star-tex.org/... to provide the MathJax-like capabilities. (once star-tex.org/... is ready and exports a nice Go API.)

Installation

$> go get github.com/go-latex/latex/...

Documentation

Documentation is served by godoc, here:

• godoc.org/github.com/go-latex/latex

The main use case for go-latex/latex is to draw a mathematical equation. This is typically achieved via the latex/mtex.Render function that knows how to render mathematical TeX equations to a renderer interface.

Example

package main

import (
	"os"

	"github.com/go-latex/latex/drawtex/drawimg"
	"github.com/go-latex/latex/mtex"
)

func main() {
	f, err := os.Create("output.png")
	if err != nil {
		panic(err)
	}
	defer f.Close()

	dst := drawimg.NewRenderer(f)
	err = mtex.Render(dst, `$f(x) = \frac{\sqrt{x +20}}{2\pi} +\hbar \sum y\partial y$`, 12, 72, nil)
	if err != nil {
		panic(err)
	}

	err = f.Close()
	if err != nil {
		panic(err)
	}
}
