2. A command to access the keys and labels of a assignment list at
user level, e.g.
\def\myassignmentlist[#1]%
{\def\dosomethingwithkeyandvalue##1##2##3{... ##2 ... ##3}% ##1 =
namespace (not used here)
\dogetparameter\dosomethingwithkeyandvalue[...][#1]}
\myassignmentlist[..,..=..,..=..]
is this the best name? maybe
\getmyparameters[a=1,b=]\handler
Looks good but in the form
\processassignmentlist[a=1,b=2,...]\docommand
and (as equivalent to \processcommacommand)
\processassignmentcommand[\mylist]\docommand
where \docommand is defined as
\def\docommand#1#2{...} % #1 = key, #2 = value
i added
\def\processassignmentlist[#1]#2% #2 == \command{key}{value]
{\def\doprocessassignmententry##1{#2}% {##2}{##3} % namespace is ignored
\dogetparameters\doprocessassignmententry[][#1]}
\def\processassignmentcommand[#1]%
{\normalexpanded{\noexpand\processassignmentlist[][#1]}}
test case:
\def\showpair#1#2{key:#1, value:#2\par}
\processassignmentlist[a=1,b=2]\showpair
