This vim plugin adds a command for LaTeX files to extracts the beamer frame that is under the cursor. If editing file spam.tex, the extracted frame is saved to spam-frame.tex that includes:

• the full preamble from spam.tex
• the source code of the current frame
• \end{document}

If the cursor is currently not within a frame, a dummy frame is saved instead.

Note that LaTeX source code is extracted from the saved file and not from the live buffer in order to rely on a content whose consistency is under user's control. Note also that the plugin expects \begin{frame}, \end{frame}, \begin{document}, and \end{document} to be written at the beginning of lines without anything before except possible spaces.

Automation can be performed by asking vim to run the command every time the file is saved:

autocmd BufWritePost,FileWritePost *.tex :BeamerFrameExtract

Then, launch latexmk spam-frame or other automated compiler to get an up-to-date PDF of the frame currently edited. The plugin does not take care of compilation, it just extract and save the relevant source code.

The plugin requires python3 to be available in vim.
