Hi,
is it possible to access a structureuservariable before the
heading’s title ?
Using the «before» key does not seem to work.
There are ways but not in a general way because you try to access
the values
before they are known to ConTeXt. To provide a proper solution you
have
to tell what you're trying to achieve.
I’m just trying to output the author’s name above a chapter
heading. Do you need more information?
You can create a custom header for the chapter page and show the value
of the author key
which works without problems because the header is added after to the
finished page
after the value is available.
Another option when the name should appear in the same space as the
chapter title
is a custom layout for the title.
Yes, I’ve tried that in the original MWE:
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\setuphead[chapter][
before={Before: \structureuservariable{author}\blank},
beforesection={Beforesection: \structureuservariable{author}\blank},
insidesection={Insidesection: \structureuservariable{author}\blank},
after={After: \structureuservariable{author}\blank},
]
\def\myChapterCommand#1#2{\structureuservariable{author}\space\blank}
\define[2]\myChapterCommand{\structureuservariable{author}\blank
#1\space#2}
%\def\myChapterCommand#1#2{\structureuservariable{author}\blank
#1\space#2} % does not work
% \starttexdefinition myChapterCommand #1 #2 % doesn't work either,
but at least blanks should work
% \structureuservariable{author}
% Test
% \blank
% #1\space#2
% \stoptexdefinition
\starttext
\myChapterCommand{1}{asdf}
\startchapter[title=First][author=First Author]
\input knuth
\stopchapter
\startchapter[title=Second][author=Second Author]
\input knuth
\stopchapter
\setuphead[chapter]
[
before=,after=,beforesection=,insidesection=,
command=\myChapterCommand,
]
\startchapter[title=Third][author={Third Author}]
\input knuth
\stopchapter
\stoptext
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
Here, I’m getting «Third author» just before «3 Third». So I guess
this goes in the right direction, but \define doesn’t allow for blanks
etc. \starttexdefinition and \def on the other hand gave me erros.
You need a box to get the author on a separate line.
% \define[2]\ChapterCommand
% {\vbox
% {\structureuservariable{author}
% \blank
% #1\space#2}}
\starttexdefinition protected ChapterCommand #1#2
\vbox\bgroup
\structureuservariable{author}
\blank
#1\space#2
\egroup
\stoptexdefinition
\setuphead
[chapter]
[command=\ChapterCommand]
\starttext
\startchapter[title=First][author=First Author]
\input knuth
\stopchapter
\startchapter[title=Second][author=Second Author]
\input knuth
\stopchapter
\startchapter[title=Third][author={Third Author}]
\input knuth
\stopchapter
\stoptext
