C

Perl

Perl's propensity for data manipulation and quick scripting make it a very popular choice for AGI scripting. To make Perl AGI programming even easier, James Golovich created Asterisk::AGI, a module designed for simplifying AGI interaction. Asterisk::AGI is available from the author's web page at http://asterisk.gnuinter.net/.

Without using Asterisk::AGI, this is what a simple AGI script to tell a user their phone number would look like. 


			#!/usr/bin/perl -w
			
			use strict;

			$|=1;
			
			#Get the initial data
			my %input;
			while(<STDIN>) {  
			        chomp;
			        last unless length($_);
			        if (/^agi_(\w+)\:\s+(.*)$/) {
		                	$input{$1} = $2;
		        	}
			}

			print "stream file the-number-is";
			print "say digits $input{callerid}";
			print "exec WaitMusicOnHold 2";
			print "hangup";
Note the $| set to force a buffer flush after each print.

Using Asterisk::AGI, we can simplify the previous script a bit: 


			#!/usr/bin/perl -w

			use strict;
			use Asterisk::AGI;
			
			$AGI = new Asterisk::AGI;
			my %input = $AGI->ReadParse();  #Read in the initial data
			
			$AGI->stream_file('the-number-is');
			$AGI->say_digits($input{callerid});
			$AGI->exec('WaitMusicOnHold','2');
			$AGI->hangup();
