Hi,
\checkparameters seems broken in the current beta. The following example
used to work at least with version 2012.06.13
---------------------------------------------------------------------------------
\def\myCom[#1]{%
\checkparameters[#1]
\ifparameters
\getparameters[do][one=1,two=2,#1]
\doone\ \dotwo
\else
#1
\fi
}
\starttext
\myCom[one]
\myCom[one=one,two=two]
\stoptext
---------------------------------------------------------------------------------
… while with the current beta (2012.08.02) it results in:
system > tex > error on line 11 in file
testcheckparameters.tex: Undefined control sequence ...
1 \def\myCom[#1]{%
2 \checkparameters[#1]
3 \ifparameters
4 \getparameters[do][one=1,two=2,#1]
5 \doone\ \dotwo
6 \else
7 #1
8 \fi
9 }
10 \starttext
11 >> \myCom[one]
12
13 \myCom[one=one,two=two]
14 \stoptext
\checkparameters ..._helpers_get_empty_parameters
#1=@@\_e_o_s_
\myCom [#1]->\checkparameters [#1]
\ifparameters \getparameters
[do][one=1,t...
l.11 \myCom[one]
Thanks in advance,
Daniel

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}
