Scriptlets in CF Anyone?

By barneyb on June 14, 2008

My last post about Comparators via CF Groovy was simplistic in nature, but the underlying concept is incredibly powerful.  Here's a similar snippet (from the demo app), this time using a Comparator class:
<g:script>
Collections.sort(variables.a, new ReverseDateKeyComparator())
</g:script>
So what do we have here?  Why it's a snippet of Java embedded directly in your CFML page, and it gets [...]

FB3 Lite Updates

By barneyb on May 26, 2008

After 6 months of use in the wild, I decided to consolidate and republish a couple mods I've made to the framework. The core functionality is unchanged, so for background, check my original post from last year. The enhancements, in no particular order, are as follows:

Changed the config at the top of index.cfm [...]

Checkbox Range Selection Update

By barneyb on May 12, 2008

Just a little update to my checkbox range selection jQuery plugin to allow chaining.  I'd forgotten to return 'this' at the end of the function.  Here's the full source, including the mod:
(function($) {
$.fn.enableCheckboxRangeSelection = function() {
var lastCheckbox = null;
var $spec = this;

Prototype's Array.any/all with jQuery

By barneyb on May 8, 2008

I needed to convert a couple Array.any() and Array.all() calls (from Prototype) to jQuery syntax. Since jQuery doesn't extend the built-in objects with nice functionality like this, you have to fake it. Here's what I came up with. Old version ('images' is an array):
images.all(function(o){return o.status == "ready";})
and the new version:
jQuery.inArray(false,
jQuery.map(images, [...]

Prototype and jQuery

By barneyb on May 7, 2008

Since I discovered it a few years ago, I've been a big Prototype fan.  It's simple, and gets the job done with a minimum of fuss.  It's not without warts, of course.  I still occasionally forget to put 'new' in front of Ajax.Request, and some of the Ruby-like methods share their lineage's arcane naming.  When [...]

IndentXml CF UDF

By barneyb on May 1, 2008

I had a need to fix indentation of some XML today, and a quick Googling didn't turn up much help. So I wrote a little UDF that will take an XML string and return it with all the tags nicely indented:

FlexChart Updates

By barneyb on April 29, 2008

The past month or so has seen quite a few improvements and bug fixes to FlexChart, though I haven't blogged about any of them.  Most notably, there was a weird NPE that manifested itself when loading a Pie chart via FlashVars.  For some unknown reason, Flex/Flash didn't give any indication the error was occurring, it just silently [...]

Data Mining With Weka

By barneyb on April 24, 2008

I've a large application that has a as a major component rank-based prioritization of assets. Users rank the assets on a one-to-five scale, and then that rank data is used to select other assets of interest for the user. If you've seen Amazon's "Recommended for you" or Netflix's recommended titles, you get the [...]

Read-Only and Read-Write SVN Repositories

By barneyb on February 28, 2008

Just got a comment on one of my posts from a while back about public SVN access wondering how to get it configured.  The basic idea is to have a single repository with anonymous read-only access, and have the same repository allow read-write access to authenticated users.  Further, you want to configure that on a [...]

Barney and the Holy Grail

By barneyb on February 11, 2008

Yes, I know it's Lent, but I'm not talking about that Grail – I'm talking about Grails, the web framework for Groovy (the dynamic layer for Java).
I've been looking for a way to ditch CFML for a while now, but nothing has really hit the mark. I keep hoping that Adobe is going [...]
