in reply to CFML Parser - testing. Design/Implementation suggestions.

I was playing with your test page and was confused at first about what the Template Variables field was for. Then I read your post more carefully and found the bit about 'global' variables.

After seeing a couple of examples of templates elsewhere, I modified your default template to look so: 

Hello World!
Welcome, <cfoutput query='bar'>#foo_name#</cfoutput>!

<cfoutput>Math result = #res#</cfoutput>

For those who haven't seen the default template, I removed the first two lines that initialize the template variables foo_name and res. I then used the following in the Template Variables field: foo_name="Jim",res=5**3 I noticed that the res value was not calculated in the Parser Output window: 
Hello World!
Welcome, "Jim"!

Math result = 5**3

What function or syntax would be necessary necessary in the template to cause it to interpolate the expression? Apologies if this is a silly question, but I don't know anything about Cold Fusion though I found your post interesting and as a nutty but wise monk once chided me:
"testers" can't hurt ;)(and usually, they learn something)
Touché.

    Thanks for your question ;-). There's nothing wrong with your quest, and I deeply appreciate your curiosity. ;D.

    The probelm with my current template parser is that the I use standard Perl eval() for expressions at the moment and _only_ if you set a variable via <CFSET> tag. Setting a variable via parameter list (the test page) is equivalent to this assignment in perl: 
    $foo_var = 'foobar';

    If done via CFSET however, the expression should be evaluated, since that's how CFSET handler class was coded to perform.
    Whilst Perl eval()'s enough for testing, there'll have to be a CFML compatible eval() in place in order for this to work well. In many respects Perl eval() would be similar to CFML eval.
