varScoper
Project Homepage:
http://www.schierberl.com/varscoper


Installation Instructions:
	Extract all files to a publicly accesible directory on your CFMX 6 or 7 server.  
	Navigate to index.cfm or varscoper.cfm and enter the absolute or relative 
	path to the template or directory that you would like to check. 

History
	-v1.3
		-CF Builder Extension Support
		-Recognizes var statements anywhere in a function (CF9)
		-Issues (13,14,15,16,17,18,19,20,21,23,25,26,27,28,30,31,32) Fixed
		-Open BD/Railo Supported
		-CFScript comments parsed correctly
	-v1.2
		-Significant improvements to cfscript parsing engine
		-Issues (6,7,8,9,10,11) fixed
		-Ability to exclude files/folders using properties.xml (only when parsing a folder)
		-Ability to identify tags with "multiple personalities" i.e. cffeed/cfprocparam that can have different behaviors for output variables based on params
		-More agressive var scope checking (newly identified scenarios that were missed before)
		-Addition of unit testing suite
	-v1.12
		-added new tags to the parsing engine
		-added XML output support
		-fixed some bugs related to directory parsing in CF6
	-v1.1
		-added support for cfscript
	-v1.0
		-initial release
		-cf tag support
		-Find unscoped variables created with a cfset within a cffunction
		-Find unscoped variables created with cftags (cfloop, cfquery, etc)
		-Report line numbers and link directly to the line in the file
		-Output to screen or csv






Features:
	-Identifies unscoped variables within cffunctions
	-can return line numbers of functions/variables

Known Limitations:
	
	-(fixed 1.13) Returns false positive when variables are set within a comments block 
	-(fixed 1.13) If you don't scope an argument value, and then reference that value it 
	 will "technically" return a false positive...
		<cfargument name="foo">
		<cfset foo.foo2 = bar /> 
	instead of...
		<cfset arguments.foo.foo2 />

Future TODOs:
	-(fixed 1.13) create a library of all cf tags that can create variables
	-(fixed 1.13) cfscript
	-(fixed 1.13) ignore things in comments (May need to use lookbehind?  Not supported in CF as far as I know)
	-Integration with cfeclipse

How can I help?
	-I need help extending the testCaseCFC file.  If you come across false positives (or negatives)
	 within your code, please send me a snippet so I can add it to the testCaseCFC
	-I need help finding all cftags that create variables (cfloop, cfquery, etc)
	 I'm sure there are some corner cases out there, I'd like to compile a comprehensive list.
