Welcome to Sorcerer's Isle, a weblog covering a multitude of topics, ranging from programming to 3D graphics; photography to gadgets; tutorials to tinkering. ColdFusion

<p>I've just encountered a very annoying bug with the expandPath function in CF8.</p> <p>Take the following code:</p> <code class="block">&lt;cfset MyDir = "."/> &lt;cfloop index="i" from="1" to="5"> &lt;cfset MyDir = expandPath(MyDir)/> &lt;cfoutput>&lt;br/>#MyDir#&lt;/cfoutput> &lt;/cfloop></code> <p>Run the code through Railo and you will get exactly the right behaviour, with the current directory output five times:</p> <code class="block">C:\dev\scratch C:\dev\scratch C:\dev\scratch C:\dev\scratch C:\dev\scratch</code> <p>Now go run the same code with CF8 - and this is what you get:</p> <code class="block">F:\ColdFusion8\wwwroot\scratch F:\ColdFusion8\wwwroot\scratch\F:\ColdFusion8\wwwroot\scratch F:\ColdFusion8\wwwroot\scratch\F:\ColdFusion8\wwwroot\scratch\F:\ColdFusion8\wwwroot\scratch F:\ColdFusion8\wwwroot\scratch\F:\ColdFusion8\wwwroot\scratch\F:\ColdFusion8\wwwroot\scratch\F:\ColdFusion8\wwwroot\scratch F:\ColdFusion8\wwwroot\scratch\F:\ColdFusion8\wwwroot\scratch\F:\ColdFusion8\wwwroot\scratch\F:\ColdFusion8\wwwroot\scratch\F:\ColdFusion8\wwwroot\scratch</code> <p>It simply stacks the current directory onto the front each time. Very frustrating.</p> <br/> <p>In order to get round this, I created a regular expression to pull off the last value of any directory containing more than one colon - this will work for Windows machines, but may need to be changed for Linux or MacOSX machines (if the bug affects these).</p> <code class="block">&lt;cfif isDefined('Server.ColdFusion.ProductName') AND Server.ColdFusion.ProductName EQ 'ColdFusion Server' AND ListLen( MyDir ,':') GT 2> &lt;cfset MyDir = REreplace( MyDir , "^.*([A-Z]:[^:]+)$" , "\1" )/> &lt;/cfif></code>

<p>I have just published the <a href="http://www.cfml-engines.info">CFML Engine Wiki</a>, a website to compare and detail the features and differences of the top CFML engines.</p> <p>There is still a lot of work to be done with it, but with it being a wiki I decided it better to release the URL and allow others to help with doing that.</p> <a class="c" href="http://www.cfml-engines.info">www.cfml-engines.info</a>
