Peter Norvig showed that it's incredibly easy to write a probabilistic spelling corrector in a very small number of lines of code. His readers, which means virtually every hacker on the planet, have ported or re-implemented his demo in a staggering number of languages.
Meanwhile, I added this to my bash profile:
I could probably re-implement Norvig's solution without even re-reading it; I read one of his AI books years ago and built an entire breakbeat improviser around probability. But where I want that probabilistic spelling corrector is in the shell. And I have no idea how you would add that to the shell, although I think some shells might already even have it.
A) Do you know which shells those are?
B) Do you know how hard it would be to add this to bash?
