Hello,
I’m using the AST functions, and I’m getting this error:
{“message”:“undefined tag [cfmail]; Failed at [path removed]”,“detail”:“”,“type”:“Error”}
I’m also not seeing the Mail setting in Services in the Server Admin UI. Am I missing something or is this a bug?
Thanks!
It’s flagged as -ALPHA for a reason! 
it’s very, very bleeding edge
7.1 is in the early move and fast and break stuff phase
stick to the 7.0 for now
Mail (and other stuff) are being moved out extensions, Lucee is going on a diet
Understood, thanks!
how are you finding the AST stuff?
So far so good!
Only complaint is that it doesn’t process comments, but I already have a workaround for re-printing those.
I’m also noticing just now that attributes for cffunction and cfargument tags aren’t appearing in the tree. Now I’m running v 7.0.0.395
use the RC!!! it has some important AST fixes
Switch to that version. Attributes are still empty:
the code is in place to do that… digging…
<cfscript>
// Test AST captures function attributes
code = 'function zac() output=false { return 1; }';
ast = astFromString( code, "script" );
systemOutput( serializeJSON( var=ast, compact=false ), true );
</cfscript>
it’s under body?

I’m using tag syntax if that makes a difference.

ahhh, indeed there’s a bug with the tag syntax
I believe I found another one:
AST loses the method name: ensureCapacity does not appear anywhere.
astFromString = astFromString( '<cfset buf.ensureCapacity(JavaCast("int", len+20))>' );

ok., keep em coming!
found a few more…
LDEV-5969 AST does not capture cffunction/cfargument tag attributes
LDEV-5975 AST dump loses method name in chained method calls
LDEV-5977 AST Ternary expression alternate value duplicates consequent
LDEV-5978 AST queryExecute adds extra variable name argument
LDEV-5979 AST isDefined adds extra scope argument
LDEV-5980 AST BIF calls keep adding internal metadata
NVM, I see the chained methods is already found by you
Hello again! Wondering if this is a bug or intended behavior. In example 1, the end offset is 65. In example 2, I add comments in the lines above each line, and the end offset becomes 46.
Example 1 - test.cfm:
Nothing but text here
Literally Nothing
No really
