Hi!
I'd like to follow up on a problem that Denis came across recently with the
titles argument in tabulate. (It's more a solution than a question, but any
hints to improve the answer are welcome.) I wanted to use this argument for an
easy specification of, well, a title for a "recipe". The advantage is that all
information is held together and it's easy to use for people who are not (too)
familiar with ConTeXt.
So, in one file I can define all styles (which the end-user would not need to
see):
\definetabulate[recipe][|l|l|p|l|]
\setuptabulate
[recipe]
[
bodyfont=small,
distance=medium,
before={\blank[back, small]},
header=text,
headstyle=\bi, % this formats the "\BC" cells
headcolor=red, % this formats the "\BC" cells
]
\starttext
And then use:
\startrecipe[title={Whatever mixture 1}]
\FL
\NC Absolute \BC Stock \NC Ingredient \NC Final \NR
\HL
\NC 1 \NR
\LL
\stoprecipe
\startrecipe[title={Whatever mixture 2}]
\FL
\BC Absolute \BC Stock \BC Ingredient \BC Final \NR
\HL
\NC 1 \NR
\LL
\stoprecipe
\stoptext
etc.
However, I cannot change the way the title is styled (or spaced from the table)
unless I do "title={\bi Some text.}". However, blank commands are also stripped
off at this place. (I also don't get a clue from the source if there is any
argument to spike-in some formatting.)
So, if there is no easy way to access this one, we can work around:
\definetabulate[recipetab][|l|l|p|l|]
\setuptabulate
[recipetab]
[
bodyfont=small,
distance=medium,
before={\blank[back, small]},
% header=text, % THIS MUST NOT BE "text"
headstyle=bold,
headcolor=red,
]
\define\startrecipe{\dodoubleempty\dostartrecipe}
\long\def\dostartrecipe[#1][#2]#3\stoprecipe{%
\iffirstargument
{\bi #1}\blank[medium]
\fi
\ifsecondargument
\startrecipetab[#2]
#3
\stoprecipetab
\else
\startrecipetab
#3
\stoprecipetab
\fi
}
\startrecipe[Head 1]
\FL
\BC Absolute \BC Stock \BC Ingredient \BC Final \NR
\HL
\NC 1 \NR
\LL
\stoprecipe
\startrecipe[Head 2][headcolor=blue] % pass on arguments to tabulate
\FL
\BC Absolute \BC Stock \BC Ingredient \BC Final \NR
\HL
\NC 1 \NR
\LL
\stoprecipe
Small question though: Is there a ConTeXt way to "\long\def" or a simple way
("user interface") to filter a list of arguments for a specific key=val pair,
e.g. to make a single optional argument with headertitle={Some header.}?
Best
Benjamin
