I've written a set of functions for interfacing CMUCL
application programs to the CGI server, so that the CMUCL
application programs can be run as WebServer/CGI applications.

For reading in the encoded HTML FORM contents and converting to assoc-list:
(defun read-anything-waiting ()
(defun cl-sleep (n) ;Workaround for bug in SLEEP function in CMUCL
(defun read-anything-within-times (nsec)
(defun combine-reverse-strings-to-big-string (revstrs)
(defun read-all-input-until-nomore ()
(defun decode-single-plus-string (str)
(defun decode-single-percent-string (str)
(defun decode-single-percent-plus-string (str)
(defun decode-equal-pair (pr)
(defun decode-html-form (form)
;Everythng above are bottom-up parts of the following one useful function:
(defun cgi-read-decode-form ()

For transmitting various HTML syntax primitives back to the client/browser.
(defun emit-cgi-header-html ()
(defun emit-form-start (filnam)
(defun emit-form-hidden (name value)
(defun emit-form-edittext-oneline (size maxlength name value)
(defun emit-form-textarea (name rows cols virwrap inittext)
(defun emit-form-checkbox (name value debflg text)
(defun emit-form-radio (name value chkflg text)
(defun emit-select-start (name)
(defun emit-select-option (nam1 val1 nam2 val2 text)
(defun emit-select-end ()
(defun emit-form-submit-button (label)
(defun emit-form-end (seenflg)
(defun emit-href (url text)

;For managing temporary disk files based on the PID (Process
;IDentification number), so that several users can each run
;(different copies of) the same application without
;interference between them - Written but not yet included in
;this library.

;For setting and checking cookies to establish login
;sessions i.e. contexts that last over more than one
;client/server exchange - Not yet written, and I would like
;to use existing code rather than figure it all myslef.
;Anybody know of any that exists and which I could use for
;free?
