px.el is an Emacs Lisp library that provides functions to preview LaTeX codes like $x^2$ in any buffer/mode.

Most of this code comes from weechat-latex.el which in turn uses org-mode previewer.

Installation

Place px.el somewhere on your load-path and load it.

Usage

Use px-preview-region to preview LaTeX codes delimited by $ pairs in the region.
Use px-preview to process the whole buffer.
Use px-remove to remove all images and restore the text back.
Use px-toggle to toggle between images and text on the whole buffer.
