[Asterisk-Dev] Oh what could the if-then-else syntax in AEL be?

[Brian Capouch]

The parser doesn't like the example in README.ael:

if (${DIALSTATUS} = "BUSY") {
                         Voicemail(${EXTEN}|b);
		} else
                         Voicemail(${EXTEN}|u);
         };

***************

Maybe it should be like C, with an open brace ahead of the else clause:

  if (${DIALSTATUS} = "BUSY") {
                          Voicemail(${EXTEN}|b);
                 } else {
                  Voicemail(${EXTEN}|u)
	};

Parser doesn't like that one, either:
Jul  6 03:12:12 WARNING[4125]: pbx_ael.c:129 __grab_token: Syntax error 
at line 33 of 'extensions.ael', too many closing braces!
******************

So, I can get the parser to shut up if I put a semicolon after the if() 
part statement:
  if (${DIALSTATUS} = "BUSY") {
                          Voicemail(${EXTEN}|b);
                 }; else {
                  Voicemail(${EXTEN}|u);
                 };

(Ahhhh.)

Only problem is, now the parser things the if() statement ends after the 
if() part, so at runtime Asterisk wonders what application "else" might be:
Jul  6 03:14:40 WARNING[4269]: pbx.c:1648 pbx_extension_helper: No 
application 'else' for extension (macro-std-exten-ael, s, 9)

********************

Something is borked, I fear. . . I'm pounding on it, but so far several 
hours of changing things around in extensions.ael still yield me no joy.
