checkparameters and current beta (20120802)

[Daniel Schopper]

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}
