[Users] unified pseudo-variables in avpops and xlog

Hello, the avpops and xlog module are using now same format for specifiers to print formatted strings. avpops has a new function avp_printf(dest, format) which stores in the AVP 'dest' the string resulted after substitution of the specifiers from "format" parameter. The old marker for specifiers '%' has been replaced by '$' which is more common for variables. To specify a header or an AVP you have to use now $hdr(header_name[index]) or $avp(avp_id[index]). The list with all available pseudo-variables in OpenSER is posted at: http://openser.org/docs/pseudo-variables.html avp_printf() allow to compose a value from many parts of a SIP message, other avps and many other values taken from system. For example: avp_printf("i:20", "the time is $Tf, the request is a $rm and has the from header $hdr(from)"); The documentation for avpops and xlog module has been updated on CVS, too. Note that these features are available only on CVS head (development version - http://openser.org/index.php#download). Online documentation site for modules (http://openser.org/docs/) has been split in 0.9x (stable) and 0.10.x (devel) directories. Follows the integration of same format for pseudo-variables in textops, acc and tm. We will appreciate any feedback. Daniel
