You have to change this on syst-aux.mkiv:
\unexpanded\def\checkparameters[#1]%
- {\syst_helpers_get_empty_parameters#1=@@\_e_o_s_}
+ {\syst_helpers_check_parameters#1=@@\_e_o_s_}
You can also use \doifassignmentelse to check the content of your macro.
\def\mycommand[#1]%
{\doifassignmentelse{#1}
{\getrawparameters[mycommand][one=1,two=2,#1]%
\mycommandone\ \mycommandtwo}
{#1}}
When you want to use \if… \else … \fi in your command you can use this:
\def\mycommand[#1]%
{\doifassignmentelse{#1}\donetrue\donefalse
\ifdone
\getrawparameters[mycommand][one=1,two=2,#1]%
\mycommandone\ \mycommandtwo
\else
#1%
\fi}
