A Python3 based Backus-Naur poetry generator.
This program works on the basis that every word in the English language is either "positive" or "negative." For instance "lovely" is positive and "thorn" is negative. A "poem" is a group of sentences that are structured in a way to have +1, -1 or 0 in terms of the positivity/negativity. A "mushy poem" is strictly positive.
All the syntax and word choices are in the poem.bnf file. The main program is in poem.py and for web applications use the poem.php script to automatically generate a poem onload!
