AEL does not offer this feature of .conf scripts.<br>
<br>
Practical example. We are using many customer "applications". An application name is also a queue name, among a few other things. Also, there is an optional per-customer set-up macro, invoked like this:<br>
<br>
if (${DIALPLAN_EXISTS("setup-${CUSTAPP}",s,1)}) {<br>
GoSub(setup-${CUSTAPP},s,1);<br>
}<br>
<br>
Now, GoSub() causes a warning when compiling AEL file. Something we could live up to now. But the use of `s' here is relying on undocumented behavior of AEL.<br>
<br>
So, between 1.8.1.1 and 1.8.3.rc2 it changed. Macros are no longer using the `s' extension as their entry point, rather `~~s~~'. That seems like a completely internal affair between AEL compiler and the dialplan, but thinking along these lines means there is no such an optional gosub feature in AEL at all.<br>
<br>
Or I can test for both `s' and `~~s~~' in the script, to maintain the hack compatible both with 1.8.1 and 1.8.3, but obviously I do not like that either.<br>
<br>
There should be a clean and documented way of doing exactly that. Going AEL should not mean self-limiting to fewer features of Asterisk.<br></blockquote><div><br>In the beginning, we implemented macros with macros. But, there is a limit of about 7 levels, and then you crash. So I changed AEL to<br>
implement macros with gosubs instead. Now you can use recursion to your heart's content. My advise: don't mix AEL macro calls with gosubs.<br>Really, there should be little to no need. It'll only complicate things. Need to use routines in extensions.conf? Take a few minutes and rewrite them into AEL.<br>
<br>If you need to do some real low-level tweaks in extensions.conf, then mimic the conventions of AEL there. (Look at the code AEL generates for macros as an example).<br><br> Best of luck!<br><br>murf<br><br></div></div>
