Yesterday I was doing some training and my student asked me to explain the logic behind this code:
<cfif 1> <cfdump var="#dharma#"> </cfif>
It was something so obvious to me that it never occurred to me that it may be confusing, and looking at it with a fresh eye I can definitely see it doesn't make much sense. Here is the method behind my madness...
Laziness. We've all had cases where we are working on a page and we need to quickly add some debug code to a page. Typically we just type it in like so:
Then if we want to hide it, but we know we aren't quite done yet, we replace it with this:
<!--- <cfdump var="#dharma#"> --->
So now to go back and forth we can add and remove the CFML comments. Well I'm lazy. I pride myself on my laziness. I don't want to have to add/remove CFML comments. Plus I tend to typo that particular set of code. So I will often use the cfif 1 code instead. When I want to hide it, I switch to:
<cfif 0> <cfdump var="#dharma#"> </cfif>
In case folks don't get what the 1 and 0 means, they are shorthand for true and false. ColdFusion considers any non-zero number to be true.
