WARNING: WORK IN PROGRESS

This project adds support for the pop11 language to the Vim editor. It handles syntax highlighting for *.p files.

We recommend you use Plug or another vim plugin manager.

For example, using Plug you would add the following to your ~/.vimrc:

Plug 'GetPoplog/vim-poplog'

Each part here corresponds to a railroad diagram from "Pop-11: A practical Language for Artificial Intelligence" (R. Barrett, A. Ramsay, A. Sloman). The syntax in this book is out of date, but it is a good starting point.
