FCKEditor for the Radiant CMS
In my experience customizing and deploying CMSs for clients, 99% of folks want a WYSIWYG editor, for good or ill. Usually good.
I’ve customized the FCKEditor for various projects, and I like:- the way it uses “connectors” to allow for the integration of the WYSIWYG with in-site assets / resources and file uploads,
- that it generates clean HTML for the flexibility the WYSIWYG provides,
- and it’s good at not molesting any custom HTML you throw in.
So I’ve made a Radiant FCKEditor extension and put it on github.
See the readme for install instructions, requirements and other crap.

Features
- In-WYSIWYG file uploads and image placement,
- Spellchecking – provided aspell is installed,
- Radius-tag awareness – I did my best to tell FCKEditor to leave radius tags alone, even customizing the tags it should ignore at the PageType level,
- Works everywhere FCKEditor does,
- Implemented as a “filter”, allowing you to manage arbitrary numbers of page parts with it,
- You can dynamically add / remove it from page parts as you see fit.
The Future
- Create an admin tab to allow for editor toolbar customization,
- Integrate the link browser to allow for dirt-simple in-site linking,
- Offer optional integration with the page_attachments plugin for more logical file organization.

"Flexmenu" style menus in the Radiant CMS
I have no idea if there’s a term to describe this kind of navigation, but I’ll use “flexmenu” as it’s what the excellent WebGUI CMS calls them, implemented via nested ul / li tags.
I like this method of site navigation as it gives a user the ability to see the entirety of the site along with the ability to zoom in / out easily and bounce between sub-sections.
As you drill down into the page hierarchy, the siblings of each page stay open. I’ll try to illustrate:
At the root, where “1” is the root.
1.1
1.2 <-- User clicks this
1.3
1.4
Next:
1.1
1.2
1.2.1
1.2.2
1.2.3 <-- User clicks this
1.2.4
1.2.5
1.3
1.4
That opens up.
1.1
1.2
1.2.1
1.2.2
1.2.3
1.2.3.1 <-- leaf node
1.2.3.2 <-- leaf node
1.2.3.3 <-- leaf node
1.2.4
1.2.5
1.3
1.4
User clicks a completely separate part of the tree, and the 1.2 branch closes.
1.1
1.2
1.3 <-- User clicks here
1.3.1
1.3.2
1.3.3
1.4
This is implemented via two snippets- a container and a recursive snippet for each node:
Container Snippet
<r:if_parent>
<div id="left-column-nav">
<r:find url="/">
<ul>
<r:snippet name="menu-line" />
</ul>
</r:find>
</div>
</r:if_parent>
Recursive Snippet, named “menu-line”
<r:children:each>
<li<r:if_self> class="active"</r:if_self>><r:link />
<r:if_ancestor_or_self>
<r:if_children>
<ul>
<r:snippet name="menu-line" />
</ul>
</r:if_children>
</r:if_ancestor_or_self>
</li>
</r:children:each>
To use an example from a real site, when at the page ”/about/people/”, this navigation menu will yield HTML similar to:
<div id="left-column-nav">
<ul>
<li><a href="/about/">About</a>
<ul>
<li><a href="/about/goals/">Goals</a></li>
<li><a href="/about/history/">History</a></li>
<li><a href="/about/mission/">Mission</a></li>
<li class="active"><a href="/about/people/">People</a>
<ul>
<li><a href="/about/people/executive-committee-members/">Executive Committee Members</a></li>
<li><a href="/about/people/other-committees/">Other Committees</a></li>
</ul>
</li>
</ul>
</li>
<li><a href="/news/">News</a></li>
<li><a href="/programs/">Programs</a></li>
<li><a href="/publications/">Publications</a></li>
<li><a href="/resources/">Resources</a></li>
<li><a href="/morville-house/">Morville House</a></li>
</ul>
</div>
Nicely nested and easily styled via CSS.
Creating image buttons with Ruby and RMagick
Below is a simple script that saved me some time – for various reasons I had to replace horrid image buttons used on a web site with more compliant-looking image buttons. You could get buttons that look exactly like this via CSS, but in this case swapping out the images was the easiest fix.
In comes RMagick , the ruby interface to the venerable ImageMagick graphics library.
First you create the canvas, then you create the Magick::Draw object that you draw onto the canvas. On linux/unix machines you can directly display the image, too via canvas.display.
The script:
#!/usr/bin/env ruby
require 'RMagick'
[
['add to basket','buy.gif',100],
['change','change.gif',60],
['checkout','checkout.gif',75],
['continue','continue.gif',75],
['continue shopping','continue_shopping.gif',130],
['go','go.gif',30],
['next','next.gif',45],
['place order','place_order.gif',90],
['previous','previous.gif',70],
['product list','product_list.gif',90],
['update','recalculate.gif',60],
['submit','submit.gif',60],
['update','update.gif',60],
['please wait','wait.gif',90]
].each{|button|
canvas=Magick::Image.new(button[2],25){
self.background_color='#BED8F1'
}
d=Magick::Draw.new
d.stroke('transparent')
d.fill('black')
d.font='/var/lib/defoma/x-ttcidfont-conf.d/dirs/TrueType/Verdana_Bold.ttf'
d.pointsize=11
d.font_weight=Magick::BoldWeight
d.text(0,0,button[0])
d.text_antialias(false)
d.font_style=Magick::NormalStyle
d.gravity=Magick::CenterGravity
d.draw(canvas)
canvas=canvas.raise(3,3)
# canvas.display
canvas.write(button[1])
}
The result:

Saved me some time, and I learned a bit out Rmagick in the process.
