Alexander Eist

This package can convert LaTeX documents to HTML pages.

It provides a script that can take the name of a LaTeX file stored in a directory as a parameter.

The script can read and process the LaTex document file and generate HTML to display the document contents on a Web page.

The package includes sample LaTeX files to publish scientific documents as an HTML page.

The formatting instructions supported by this script include the LaTeX, MathJax, and a few added formatting roles.

Hello here! Here you will find a simple LaTexP decoding machine (LaTeX MathJax Plus origin formatting rooles) for scientific articles for publication in HTML format. System Requirements - PHP ver 8 or later A complete list of the commands used is given in the LaTexP-file that opens by default. All texts are made using neural networks, whose names you will find in the menu. How to use: Menus and submenus are generated automatically in any language. It is enough to upload to the server into the project directory in the data folder of the categories's folders and into them any documents in LaTexP format (extended latex plus format) text with the extension .tex. Make the file name for publishing according to the following template: < any name in any language > .tex Note: the version of PHP must be 8.x
