It feels limiting that code inside <%...%> will only be bound to the global
context.
I may have mentioned this before but there's my ML dialect which creates
HTML markup from Rebol words, paths and other values. It makes the
HTML/XHTML look like Rebol script. For example, the Envelope function my
Rebol/Wiki:
Envelope: func [Title [string!] Body [block!]] [
content-type 'text/html
print newline
print ML compose/deep [
<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE html PUBLIC
"-//W3C//DTD XHTML 1.1 plus MathML 2.0 plus SVG 1.1//EN"
"http://www.w3.org/2002/04/xhtml-math-svg/xhtml-math-svg.dtd";>
html [
head [
title (Title)
link/rel/type/href "stylesheet" "text/css" (Stylesheet)
script/type/language/src "text/javascript" "JavaScript"
%Wiki.js ""
]
body/onload/id "SetColumnHeight (HtmlElement)" "HtmlElement"
[(Body)]
]
]
quit
]
The view page function uses the above and looks something like:
Envelope Title compose/deep either file? Page [
[
(Folder_Buttons Page)
div/id "Center_Column" [
(
eText/Wiki/Base read Wiki_Folder/:Page rejoin [
CGI/Script-File #"?"
]
)
]
div/id "Commands" [
(Random_Page/GUI)
(Search/GUI Title)
(Edit_Page/GUI Page)
]
]
And it's done through a nice and simple parser as shown below.
