[asterisk-users] Passing literals with commas to subroutine
Hi,
Let's say I do:
Set(data=xxx,yyy)
Gosub(my-sub,s,1(${data}))
My subroutine will only receive "xxx" for ARG1. How can I pass a
literal
with a comma to a single argument in a subroutine?
(The point is: when calling the subroutine I do not know if the variable
has a comma or not.)
Thanks,
Daniel

You can escape characters with a backslash, I've not tried it in this case but it may help you. Another idea is you could encode your data with the BASE64_ENCODE or URIENCODE * functions and decode it in your subroutine. https://wiki.asterisk.org/wiki/display/AST/Function_BASE64_ENCODE https://wiki.asterisk.org/wiki/display/AST/Function_URIENCODE * I'm not certain if URIENCODE will escape the comma, it sounds like it should reading the RFC.

I've managed to set myself up a temporary Asterisk box, so I was able to do some testing without risking bringing down a production server :) And I have managed to put together a solution, if you can call it that. If you put speech marks around the argument, like so: Gosub(my-sub,s,1("${data}")) then what actually comes through in ${ARG1} is "xxx,yyy" (complete with the speech marks). But at least that comma is protected. So then within my-sub, you just need to evaluate ${ARG1:1:-1}, ${ARG2:1:-1} &c. to strip off the first and last characters (skip one, show all but one). It's a bit ugly -- but so is a lot of stuff written in the Dialplan. Just because a language is Turing-complete, doesn't mean any code written in it is going to be pretty. But you might be able to mitigate some of the ugliness with comments (introduced with a semicolon in Dialplan, because the comment mark is a valid "digit"). -- AJS Note: Originating address only accepts e-mail from list!

The easiest way is to escape the commas is with a \ (backslash). -----Original Message----- From: asterisk-users-bounces at lists.digium.com [mailto:asterisk-users-bounces at lists.digium.com] On Behalf Of A J Stiles Sent: Thursday, December 11, 2014 7:41 AM To: Asterisk Users Mailing List - Non-Commercial Discussion Subject: Re: [asterisk-users] Passing literals with commas to subroutine [SOLVED] On Tuesday 09 Dec 2014, Daniel Gonzalez wrote:> Hi, > > Let's say I do: > > Set(data=xxx,yyy) > Gosub(my-sub,s,1(${data})) > > My subroutine will only receive "xxx" for ARG1.
