I have been playing around with my tweeked methodology of Fusebox and
cfObjects, and recently built a very rough prototype assertion checker
that uses the existing fusedocs for the information.
The way it works is:
1. Reads the file as text
2. Retrieves only the <in> elements
3. Loops through the elements checking to see if the required variables
are there, non-required have a default value and setting the values.
4. After this it includes the file requested.
I have pasted the code below here for the checker and some code for the
test.
------- Interface Node code (ide.cfm) ----------
<cfsilent>
<cfif Not ParameterExists(attributes.action)>
<cfset attributes.action ="test">
</cfif>
<cffile action="READ"
file="#GetDirectoryFromPath(GetBaseTemplatePath())##attributes.action#.cfm"
variable="Assertion">
<cfset testIt = Trim(Mid(Assertion,
FindNoCase('<in>',Assertion)+Len('<in>'),
FindNoCase('</in>',Assertion)-(FindNoCase('<in>',Assertion)+Len('<in>'))))>
<cfset r = 0>
<cfset n = 0>
</cfsilent>
<cfloop condition="Len(testIt)">
<!--- <string name="attributes.Userpass" required="No" default="nopass"
/> --->
<cfset test = Left(testIt, FindNoCase(' />', testIt)+3)>
<cfset type = Mid(test,2,FindNoCase(' ',test)-2)>
<cfset nme = Mid(test, (FindNoCase('name="', test) + 6), Len(test))>
<cfset nme = Trim(Left(nme, FindNoCase('"', nme)-1))>
<cfif FindNoCase('required="Yes"',test)>
<cfset r = r + 1>
<cfif Not Evaluate("ParameterExists(" & nme & ")")>
<cfabort showerror="Required #nme# was not present!">
</cfif>
<cfset dft="">
<cfelse>
<cfset n = n + 1>
<cfif Not FindNoCase('default="', test)>
<cfabort showerror="#nme# is listed as a non-required
variable, but
has no default value!">
</cfif>
<cfset dft = Mid(test, (FindNoCase('default="', test) +
Len('default="')), Len(test))>
<cfset dft = Trim(Left(dft, FindNoCase('"', dft)-1))>
<cfparam name="#nme#" default="#dft#" type="#type#">
</cfif>
<cfset testIt = Trim(ReplaceNoCase(testIt, test, ""))>
</cfloop>
<cfinclude template="#attributes.action#.cfm">
------- Test file ----------
<!---
<fusedoc fuse="test.cfm">

they log in to the system. I am there home screen and default screen

This is a test, I repeat this is only a test.
