Nice little hack. My favorite find of that sort came from a verse-finder in Python run over the text of The Lord of the Rings -- it was looking for scansion, not rhyme -- i.e., blank verse like Paradise Lost:
One turned to stone. A brief vision he had
Of swirling cloud, and in the midst of it
Towers and battlements, tall as hills,
Founded upon a mighty mountain-throne
Above immeasurable pits; great courts
And dungeons, eyeless prisons sheer as cliffs,
And gaping gates of steel and adamant:
And then all passed.
I suppose it's not a coincidence the longest passage the program found came at the climactic moment of the story.
This is off topic, but the code highlighting with slight background noise seems like a good idea in general. Has anyone tried this in their editor of choice?
Clicked expecting a poem that is also valid Ruby, like what people used to do with Perl. Was somewhat disappointed, but LOL'd at the Eurozone Bailout poem.
