[dev-context] \structurevariable

[Wolfgang Schuster]

Hi Hans,

the \structurevariable command which can be used the access the value in the headings don’t show any text because context looks into the wrong table.

In strc-doc.lua something like this has to be changed (use the title data subtable):

function sections.structuredata(depth,key,default,honorcatcodetable) -- todo: spec table and then also depth
    if depth then
        depth = levelmap[depth] or tonumber(depth)
    end
    if not depth or depth == 0 then
        depth = data.depth
    end
    local data = data.status[depth]
--  local d = data
    local d = data.titledata
    …
end

Example:

\setupheadertexts[chapter]

\define[2]\ChapterCommand
  {\vbox\bgroup\starttabulate
   \NC Title   \EQ \structurevariable{title}   \NC\NR
   \NC Marking \EQ \structurevariable{marking} \NC\NR
   \stoptabulate\egroup}

\setuphead[chapter][command=\ChapterCommand]

\starttext

\startchapter[title={Hello World},marking={A}]

\starttabulate
\NC Title   \EQ \namedstructurevariable{chapter}{title}   \NC\NR
\NC Marking \EQ \namedstructurevariable{chapter}{marking} \NC\NR
\stoptabulate

\stopchapter

\stoptext
