[OpenSIPS-Users] [OpenSIPS Public Meeting] Follow-up: Scripting variables in OpenSIPS 3.x

[Liviu Chircu]

Hello!

The conclusions of yesterday's Public Meeting can be found here [1]

Here is a quick summary of the decided upon changes for variable 
restructuring in OpenSIPS 3.x:

* variable referencing will now mandate an *explicit scope*(local, msg 
(read/write into the SIP msg), tm, dlg, global)
* variables will still be *dynamically typed*
* improvements to *explicit casting*(from a couple of transformations to 
int(), str(), list() and json())
* *new data types*: list and json, along with contructors and specific 
operators ("+" for concat, [] for indexing)
* *AVPs dropped*
* *NULL *special value to be kept
* find the best way of adapting the multi-index pseudo-vars, e.g. 
$(hdr(Contact)[1])

This is still an ongoing effort, any feature is subject to change as we 
go along with the development of OpenSIPS 3.0, so this is the ideal time 
to reply to this thread and suggest improvements!
