Question about *escape-char-p*

[Paul Thirumalai]

HI, Hope this is not too dumb a question.

I am trying to run the hunchentoot-test example with the hunchentoot system.
Each time I try to run the easy demo, get demo or post demo I get the error

"Error in KERNEL:%COERCE-TO-FUNCTION: the function CL-WHO:*ESCAPE-CHAR-P*
is undefined."

Could you explain why this occurs. It also happens to me when I try use the
escape-string method in code.
FYI: I changed the *attribute-quote-char* in who.lis from #\' to #\"
Thanks
Paul

Strange. Are you using the newest version of all libraries? Could
you provide a backtrace of the error? Also, we'd need information
about your Lisp implementation and OS.

I assume you mean who.lisp. But of course the idea is that you change
this value in your code and not in the source code of the library.

Cheers,

Thanks so much. Undoing the change to *attribute-quote-char* fixed the
issue.

Now I am using (setf *attribute-quote-char* #\") in my own code where ever
I need to do it.

Good.

As this is a global special variable, you shouldn't set its value but
rather bind it (with LET), see for example Peter's chapter about
variables, and the section about dynamic variables in particular:
