Re: [asterisk-users] Reasons to use AEL
I think if someone knows well how to make dialplans in regular extensions.conf file, then there is nothing much to learn about AEL. There is a page on voip-info.org on AEL ( http://www.voip-info.org/wiki/view/Asterisk+AEL) and to me it proved to be more than enough to switch to AEL. I used only that one page to learn AEL and have been creating complex dial plans for a while now purely in AEL. You can also test your AEL dialplans by doing "show dialplan and it'll show the dialplan in 'exten => ...' format, which will help you understand if you have programmed it right or not.

Can you recommend a good tutorial or book that covers AEL? I tend to use extensions.conf because most of the examples I come across use it, and it's covered by my first edition of the O'Reilly Asterisk book. Do later editions of the O'Reilly book cover AEL thoroughly?

I'd say control structures (and proper indentation) are one of the
most important reasons to use AEL (conditionals: if .. else, switch
.. case, ..., loops: for, while) because they look so familiar.
Imagine nested "control structures" in extensions.conf with Goto(),
GotoIf(), While(), EndWhile(), ExitWhile(), ContinueWhile() and
priorities - such code is not what I call maintainable.
== extensions.conf:
exten => 30,1,Set(x=5)
exten => 30,n,While($[${x} <= 9])
exten => 30,n,NoOp(x ist ${x})
exten => 30,n,ExecIf($[${x} > 5],ExitWhile)
exten => 30,n,Playback(beep)
exten => 30,n,Set(x=$[${x} + 1])
exten => 30,n,EndWhile()
exten => 30,n,NoOp(done)
== extensions.ael:
30 => {
x=0;
while (${x} <= 9) {
NoOp(x ist ${x});
if (${x} > 5) {
break;
}
Playback(beep);
y=${x} + 1;
}
NoOp(done);
}
In this example, we needed more lines in AEL; if we had added another
command to the if condition in our while loop, ExecIf() would not be
enough anymore and we would be forced to use a more complex construc-
tion with GotoIf(). Our extensions.conf would be a lot longer.
