handling key=value sets with lua

handling key=value sets with lua

hi list,

skip to the many %%% if you just want to help me ;)

i need to make a macro which consists of ten optional arguments. it wouldn’t
be too ugly to require to write the following to use it, since it outputs a
3×3 matrix with an adjacent tenth item, but tex can’t handle ten arguments
afaik.


syntax idea:
empty:
\bigcrafting%
{}{}{}%
{}{}{}{}%
{}{}{}%

partly filled:
\bigcrafting%
{}{}{}%
{planks}{planks}{}{workbench}%
{planks}{planks}{}%

how it should look:

ok, since using empty “required” arguments aren’t elegent, either, i wanted
to get into key=value sets, but ran into the next problem:

i wanted to instead define bigcrafting to work like this:
\bigcrafting
  [21=planks, 22=planks,
   31=planks, 32=planks]
  [workbench]

but \getparameters<http://wiki.contextgarden.net/Commands_with_KeyVal_arguments>can’t
handle numerical values.

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

and while points of the compass like NE, S and C (for center) would work, it
sprang to my mind that a parser written in lua, whitch uses lua’s internal
hashtables would meet my furter needs better (like looping over the matrix
and testing if parameters are set) can somebody tell my how to access (and
test if they exist) the arguments (#1,[#2],…) of a command definition in
lua?

Why now?

\getparameters[MyNameSpace][1=a,2=b]

\getvalue{MyNameSpace1}

works ok.

ok, i just knew of \MyNameSpaceKey, which doesn’t work if the key consists
numbers. thanks again!
ConTeXt seems to be your personal baby, isn’t it? ;)

column and "c" for cell
i.e
\def\BigCrafting[#1]%
{\getparameters[Ph][c11={},c12={},c13={},
c21={},c22={},c23={},c24={},
c31={},c32={},c33={},#1]
\bTABLE
\bTR\bTD\getvalue{Phc11}\eTD\bTD\getvalue{Phc12}\eTD\bTD\getvalue{Phc13}\eTD\eTR
\bTR\bTD\getvalue{Phc21}\eTD\bTD\getvalue{Phc22}\eTD\bTD\getvalue{Phc23}\eTD\bTD\getvalue{Phc24}\eTD\eTR
\bTR\bTD\getvalue{Phc31}\eTD\bTD\getvalue{Phc32}\eTD\bTD\getvalue{Phc33}\eTD\eTR
\eTABLE
}
\starttext
\BigCrafting[c11=FOO,c33=GOO,c22=BOO,c24=Zoo]
\BigCrafting[c11=FOO,c24=GOO]
\stoptext

You can also use a better namespace
\def\BigCrafting[#1]%
\unprotect
\getparameters[flying-sheep@web.de:][c11={},c12={},c13={},
c21={},c22={},c23={},c24={},
c31={},c32={},c33={},#1]
\getvalue{flying-sheep@web.de:c11}%%
\getvalue{flying-sheep@web.de:c12}%% and so on
\protect
}
