Syntax Highlighting



[Edit: The slowdown caused by parsing the main chunk of javascript function was getting out of hand so i temporarily removed formatting from this block. It will now look terribly ugly but i plan to update the formatting mechanism at the weekend to allow collapsed text to be formatted on expansion rather than page-load.



I was recently asked about the code syntax highlighting on my blog. I can't take any credit for it (except for the little time it took me to mash somebody else's code into a single page. The code itself is courtesy of Alex Gorbatchev and is available in it's entirety at
http://code.google.com/p/syntaxhighlighter/ under the terms o the GNU Lesser General Public License.

Please beware (if you haven't noticed already) that highlighting big blocks of code requires a relatively large amount of client-side processing, thus slowing the page when loading and causing a little havoc. This, alas, is the nature of the beast. This syntax highlighter allows for a collapsed mode where textareas can be collapsed, thus making things a little neater. Perhaps a nice addition would be deferring the syntax highlighting for a particular region based on whether it is hidden or not....

A syntax highlighter written in Javascript, it allows keywords to be highlighted by creating a textarea, specifying its CSS class (based on the language you wish to highlight) and popping your code into said textarea as follows:




The zip archive download from the above site includes multiple .js and .css files. Since blogger (and most other blogs) only allow for a single HTML page, it was necessary to mash the code from all of these source files together and insert them into this solitary page. I did so as follows (using version 1.5.1):


  1. Compiled all of the Javascript Functions into one script region, inserted into the <HEAD> of my document.
  2. Compiled all of the CSS attributes etc. into a single style region, also added to the <HEAD> of my document
  3. Created another Javascript area at the very bottom of my document right before the </BODY> tag to call the relevant functions and begin syntax highlighting.


    The result is, as can be seen below, some beautifully highlighted code. Thanks to Alex Gorbatchev for his wonderful work.

Excel - Adding an existing Pivot table to the data model

Image
  I've been working more with, and continue to be amazed by, Power Pivot. I recently ran into an issue where I needed to add the data for an existing Power Pivot report to the Data Model. There is a checkbox that makes this easy when creating a PivotTable: As so often happens, the analysis grew in scope/importance and I found myself needing to add the data to the data model. While it's not obvious how, there is a way to add an existing Pivot table to the data model. There's a More Tables... link in the PivotTable Fields pane.  Clicking on the  More Tables... results in a dialog confirming that you want to Create a New PivotTable .  Doing so will result in the creation of the new PivotTable in a new sheet. By default the data is added to the data model. You'll likely lose some formatting but for anything other than a trivial PivotTable, this should save effort, as it did for me.

Mirth

Image
Introduction Let's talk about Mirth. At it's simplest, Mirth  link is an Open Source HL7 interface engine. HL7 (Health Level 7) is an NPO involved in the development of healthcare standards and the HL7 v2.x and HL7 v3 standards are commonly used in Medical Information for data interchange - including but not limited to clinical, financial, logistical and administrative messaging. I first ran across Mirth over a year ago on a personal quest to find an alternative to our client's legacy HL7 application. Academically, I wrote a number of lexical analysis tools using lexx, yacc, bison and JavaCC and knew the challenges of writing and maintaining complex parsers. I was simply looking for something that could parse HL7 for us, and perhaps log messages and provide a little more transparency than our application currently allowed.  A year later and our legacy application is still going strong (read: my proposal was declined), but Mirth is being used in production, far away from th

Getting Started with Mirth (Part 1)

Image
This is the first post in a 2 part series. The second post is here Recently I posted about my positive experience when using Mirth by Webreach as an open source communication layer between one of our in-house applications and a third party and proprietary web service interface. That post received a large amount of attention (relative to my other posts :o) ) so now I will post a quickstart guide to creating a similar setup. In this post I will go over the very basics of using Mirth (please dig in and play around with some more advanced options/configurations), specifically I will demonstrate how to use Mirth to read data from a database, package the data up in a SOAP envelope, send the data to a web service and process the SOAP response. I'll also show you how easy it is to monitor channels once deployed. Once you've installed and opened Mirth for the first time you'll be presented with an empty dashboard - but it wont stay empty for long. This is where you'll s
