I've been toying with a program I want to try in Lisp, the input side
should read in plain text, emitting it as a series of strings.

So I need to make a fairly simple parser.  Putting aside the obvious
read a character, classify it and do stuff accordingly approach, is it
possible (or feasible or desirable) to fiddle with the readtable so
the reader itself can suck in the text stream and emit the words as
strings?  If yes, what would be a good direction to look in for more
info about setting up such a readtable?

Thanks,

Gregm

If you're using Common Lisp, you should read Henry Baker's excellent
article on "Pragmatic Parsing in Common Lisp". His papers have been
somewhat difficult to find since the host for his archive was shut down,
but a mirror can be found here:

ftp://samaris.tunes.org/pub/food/papers/people/Henry.Baker/

the paper on parsing is at

Cool, thanks.  Now I just have to figure it out... ;)

You can try ZEBU, a common-lisp parser.
The author always posts some update messages in this newsgroup...

And, the latest known version is available (temporarily) from my sourceforge
page:

  http://sourceforge.net/projects/lisa

I've augmented Zebu 3.5.5 to support CMUCL and added an MK:DEFSYSTEM-compatible
system definition file. Hopefully the CLOCC project with pick up ownership of
Zebu, since the software is GPL'd.
