LyX on Twig

LyX-on-Twig is a simple PHP library combining LyX and Twig to create beautiful generated documents in LaTeX. User/programmer creates template in LyX using Twig constructs, this template is compiled to LaTeX source code with Twig constructs, and finally LaTeX template is populated with data, replacing Twig constructs in the process.

Example

While editing in LyX:

Features

• Use LyX, a graphical WYSIWYM editor, to create template.
• Use Twig to populate the template with data.
• Everything in simple and easy-to-use package.

Requirements

• Texlive installed on server.
• LyX installed on developper's computer.
• Optional: LyX on server if templates should be compiled from LyX to LaTeX on server.

Usage

1. Create LyX document using lyx/twig.article.layout as a layout file. You may want to symlink this file next to your document.

2. Use LyX to export tex template: lyx -batch -e pdf5 template.twig.lyx.

3. Compile the template template.twig.tex to PDF:

   $lyxtwig = new LyxOnTwig('./', array('cache' => './cache/'));
   $output_file = tempnam(tempnam(sys_get_temp_dir(), 'output.');
   if ($lyxtwig->render('template.twig.tex', 'template.twig.pdf', array('some' => 'data'))) {
       // Do something with PDF in $output_file
   }
   

PDF Properties

Fortunately LyX does not escape PDF options (in document settings, PDF properties), so it is possible to use \noexpand\Twig{expression} to insert expression into PDF title or any other field. The \noexpand is required to stop LaTeX from expanding the \Twig macro which is not defined yet.
