Dear gurus,
This question concerns both MKII and MKIV (I need the functionality in
both, even though I will try to rewrite the MKIV part as soon as I
have time).
I have a command:
\mycommand[a][newparam=value]
with more or less the following definition:
\def\mycommand[#1][#2]{%
\getparameters[@@mycommand@#1@][#2]
% ... some extra code ...
}
However I used to use
\mycommand[a][oldparam=value]
and now I would like to switch the syntax to
\mycommand[a][newparam=value]
but I would like the oldparam to keep working normally.
I will read the value with \@@mycommand@a@newparam.
My question: what is the most elegant value to do that?
I can imagine something like
\def\mycommand[#1][#2]{%
\undefinecommand\@@mycommand@a@oldparam % pseudocode
\getparameters[@@mycommand@#1@][#2]
\doifdefined{\@@mycommand@a@oldparam}
\let\@@mycommand@a@newparam\@@mycommand@a@oldparam
% ... some extra code ...
}
but there is most probably some more elegant solution to that?
Thank you,
Mojca

MkIV:
\definenamespace
[mojca]
[type=module,
name=mojca,
command=yes,
setup=yes,
parent=mojca]
\starttext
\setupmojca
[oldkey=OLD,
newkey=\mojcaparameter{oldkey}]
\starttabulate
\NC Old \EQ \mojcaparameter{oldkey} \NC\NR
\NC New \EQ \mojcaparameter{newkey} \NC\NR
\stoptabulate
\setupmojca
[newkey=NEW]
\starttabulate
\NC Old \EQ \mojcaparameter{oldkey} \NC\NR
\NC New \EQ \mojcaparameter{newkey} \NC\NR
\stoptabulate
\stoptext
