[parenscript-devel] js-script deprecated
by Wout Perquin 17 Jan '09

17 Jan '09

Hi, I am quite impressed by ParenScript. I installed it last August, but only recently I started playing with it. Some observations/comments : - js-script was in the Aug-2007 release but now it has been deprecated. By what has it been replaced ? - the js-script didn't work with with-html-output of cl-who, so I wrote my own macro js-script to do the script-tag + CDATA stuff which is still required for scripts in the header - the tutorial (Aug-28, 2007 p3) still refers to js-script -Wout

[parenscript-devel] Generating HTML in parenscript
by Gary King 26 Nov '08

26 Nov '08

I've just started playing with Parenscript and feel confused about HTML generation. Since Parenscript already includes (the unexported) process-html-forms, it seems to be able to (almost) handle much of the logic for simple HTML generation. Consider that > (parenscript::process-html-forms > `(:html > (:head (:title "ParenScript tutorial: 1st example")) > (:body (:h1 "ParenScript tutorial: 1st example") > (:p "Please click the link below." :br > ((:a :href "#" :onclick ,(ps-inline > (alert "Hello World"))) > "Hello World"))))) produces > (+ "<html/><head><title>ParenScript tutorial: 1st example</title></ > head><body><h1>ParenScript tutorial: 1st example</h1><p>Please click > the link below.<br/><a href=\"#\" onclick=\"javascript:alert(\"Hello > World\")\">Hello World</a></p></body>") It's easy to refactor process-html-forms to arrive at the (slightly incorrect) HTML in a string: > "<html/><head><title>ParenScript tutorial: 1st example</title></ > head><body><h1>ParenScript tutorial: 1st example</h1><p>Please click > the link below.<br/><a href=\"#\" onclick=\"javascript:alert(\"Hello > World\")\">Hello World</a></p></body>" and probably easy to futz with *js-inline-string-delimiter* and the like to get the correct quotes around the body of the onclick handler. So... since Parenscript doesn't do this, I have to ask "Why not"?! It would be nice to use Parenscript for simple HTML generation without having to get (Portable) AServe or some other more full-featured HTML generator. Am I missing something? thanks, -- Gary Warren King, metabang.com Cell: (413) 559 8738 Fax: (206) 338-4052 gwkkwg on Skype * garethsan on AIM

[parenscript-devel] BUG in css-to-string?
by Stuart Overton 22 May '08

22 May '08

I'm really liking parenscript and just got started with it, so this question might be off base, but here goes... I'm writing a parenscript/cl-who/hunchentoot application, and I'm using some code along the lines of: (css-to-string '(((a.foo) (:color "green" :font-size "25pt")) ((a.foo\:hover) (:color "red")))) which generates the following string: "A.FOO { color:green; font-size:25pt; } ; A.FOO:HOVER { color:red; } " Firefox doesn't seem to like the second rule, since it starts with a semicolon. The code of css-to-string I have is: (defun css-to-string (rules) (string-join (mapcar #'css-rule-to-string rules) "; ")) If I substitute it with (defun css-to-string (rules) (concatenate 'string (mapcar #'css-rule-to-string rules))) That problem goes away and Firefox recognizes the second rule. Am I doing something wrong or is this a bug?
