\placelist summary alternative solution

\placelist summary alternative solution

[Felix Ingram]

I've ended up delving into the dark art that is Lua for this solution:

\define[0]\SummaryTable{%
\placetable[force, none]{}{%
\setupTABLE[frame=off]
\bTABLE
\bTABLEhead
\bTR\bTH Reference\eTH\bTH Title\eTH\bTH Page\eTH\eTR
\eTABLEhead
\bTABLEbody
\startluacode
    for k, v in ipairs(structures.lists.collected) do
        if v.metadata.kind == "section" and v.metadata.name == "section" then
            context.bTR()
                context.bTD()
                    context("REFREF")
                context.eTD()
                context.bTD()
                    context(v.titledata.title)
                context.eTD()
                context.bTD()
                    context(v.references.realpage)
                context.eTD()
            context.eTR()
        end
    end
\stopluacode%
\eTABLEbody
\eTABLE
}%
}%
\starttext
\section{Test}
\input{knuth}
\section{Test}
\input{knuth}
\section{Test}
\input{knuth}
\section{Test}
\input{knuth}
\section{Test}
\input{knuth}
\section{Test}
\input{knuth}
\section{Test}
\input{knuth}
\SummaryTable
\stoptext

This works to some degree though I have the following questions about it:

1. Is there a way to access a document global variable from Lua? I
will use this to replace the REFREF text.

2. v.references.realpage isn't the actual page of the title. How can I
access the page number that would have appeared in the ToC? (I've
restarted the page numbering in my master doc, the above example works
fine)

3. Is there a way to store some metadata along with my title? I'd like
something similar to this:
\myheader[author=me, date=2011-12-14]{This is my header with meta-data}
and then be able to access it from Lua again.

Thanks for any help you can give with this.

Felix

\startluacode

document.myvariables = { }

document.myvariables.whatever = "SOME TEXT"

\stopluacode

...

context(document.myvariables.whatever)

as you're looking into the code ... search for helpers like

lists.prefixedpage

keep in mind that this is not yet an official api (although it will 
probably stay this way)

it's called userdata (third argument to \startchapter etc) .. it travels 
with the rest
