ktx

ktx is a command-line interface for the math rendering library KaTeX, packaged as a zero-dependency executable file.

Type this:

$ ktx "\sum_{n=0}^\infty{\frac{(-1)^nx^{2n+1}}{(2n+1)!}}"

and get this:

Installation

ktx supports macOS 10.13 (High Sierra) and later.

1. Head over to Releases and download the latest version
2. Move it to a folder that's included in your $PATH (for example, /usr/local/bin)

Usage

# Save the result to a temporary file and open it
ktx "x^2"

# Make the font small and use inline layout mode
ktx "x^2" --size 12 --inline

# Save the result to a particular destination
ktx "x^2" output.tiff

# Save the result to a particular destination and open it
ktx "x^2" output.tiff --open

Development

Make sure you have a recent version of Xcode and Node.js. Then run these commands in a terminal:

$ git clone https://github.com/ryanbloom/ktx
$ cd ktx/JavaScript
$ npm install
$ ./node_modules/.bin/webpack --config=webpack.config.js

This will create a bundle of all the KaTeX source code and fonts at ktx/JavaScript/dist/index.html. You'll have to repeat the last command whenever you edit the JavaScript or HTML files.

Now, open Ktx.xcodeproj and build the project.
