S2 LaTeX Renderer

Service for generating nice SVG pictures from LaTeX equations for web. You can try it in action in the Markdown and LaTeX online editor.

Requirements

1. TeX Live. I prefer a full installation and disabling write18 support.
2. nginx web server with ngx_http_lua_module (for example, nginx-extras Debian package).
3. php-fpm. proc_open() function must be enabled. Add the TeX bin directory (e.g. '/home/tex/tl-2016/bin/x86_64-linux') to the PHP PATH environment variable. Otherwise there can be floating bugs with generating font files.
4. Node.js and frontend tools: npm, bower, grunt-cli. Make the following symlink on Debian: root:/usr/bin# ln -s nodejs node.
5. ghostscript (used internally by dvisvgm TeX component).
6. Utilities: rsvg-convert, optipng, pngout. Install them or modify the code to disable PNG support.
