Hi,

I was interested on implementing the Burke-Fisher error

correction(http://portal.acm.org/citation.cfm?doid=22719.22720) method

in Bison. I want to know that is there any parser generators

implemented this feature? The one I only know is the ML-Yacc,

mentioned in the book "Modern Compiler Implementation in ML".If there

weren't much parser generators implemented it, is it means that this

feature is not useful or some other reasons?

Thanks.

[Back when we punched our programs on cards, handed the decks to the

operator, and got printouts back an hour later, error correction was

very popular since it offered the chance to find more bugs per run and

decrease the number of runs until your program worked. Now that we do

everything interactively, I don't see much point in the compiler

guessing what you wanted to do rather than just point out where the

error is and letting you fix it. -John]
