If you read the code, you find the two most important functions are `regexp-hits-find-hit' and `search-regexp-in-files'. regexp means regexps! That there are examples - which work - applied on Lisp files don't change that. Now, it doesn't say *one word* about re-parsing or otherwise analyzing the code with respect imbecile, ten million times accursed computer science theory. If you want to do that - just do it! See if I will come and have 42 degrees of expedition fever and purposely misunderstand and be all negativistic. Of course, I will not - and why do you think that is? -- underground experts united http://user.it.uu.se/~embe8573
