Working with variables in MkIV (\ setvariables, \getparameters etc)

[Jaroslav Hajtmar <hajtmar@gyza.cz>]

Hello ConTeXist,

Is it possible go through  all the keys of \setvariables (getvariable) 
macro and create the appropriate macros, as in the case of 
\getparameters macro?

I mean macro like \getallvariablesfrom[myfirstnamespace], which return 
contents of brackets macro \setvariables[myfirstnamespace] (it mean list 
of all assignments key=value ...)

In addition, you can assign all the variables one namespace to another 
namespace (or to create a loop which all variables passed and placed 
into the other namespace.)?

Thanx Jaroslav Hajtmar

Here is my inspiration of example :


\setvariables[myfirstnamespace][id=1, value={text}]

\starttext

% \getparameters[myfirstnamespace][\getallvariablesfrom[myfirstnamespace]]

% Now would be defined  macros \myfirstnamespaceid  (1) and 
\myfirstnamespacevalue  (text)


% Assign all the variables of [myfirstnamespace] namespace to 
[myotherspace] namespace?
%\setvariable[myotherspace][\getallvariablesfrom[myfirstnamespace]]

\stoptext
