\structurevariable
by Wolfgang Schuster 05 Mar '12

05 Mar '12

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 Wolfgang

problems with xtable and export xhtml

It seems that xtable doesn't export @rows and @columns This patch to tabl-xtb.mkvi works, not sure if it is a good style. \unexpanded\def\tabl_x_start_cell_construct_yes[#settings]% {\dostarttagged\t!tablecell\empty % can't we just tag the box \setbox\b_tabl_x\hbox\bgroup \setupcurrentxtable[#settings] \letxtableparameter\c!width \d_tabl_x_width % overloads given width \letxtableparameter\c!height\d_tabl_x_height % overloads given height \ctxcommand{x_table_init_construct()}% \inheritedxtableframed\bgroup \tabl_x_begin_of_cell \def\tablecellcolumns{% \ifnum\csname \m_mult_interfaces_namespace nx\endcsname>\csname \m_mult_interfaces_namespace nc\endcsname% \csname \m_mult_interfaces_namespace nx\endcsname% \else \csname \m_mult_interfaces_namespace nc\endcsname% \fi}% \def\tablecellrows{% \ifnum\csname \m_mult_interfaces_namespace ny\endcsname>\csname \m_mult_interfaces_namespace nr\endcsname% \csname \m_mult_interfaces_namespace ny\endcsname% \else \csname \m_mult_interfaces_namespace nr\endcsname% \fi} \dotagxtablecell} -- luigi

Customized list alternative with hyperlinks
by Wolfgang Schuster 23 Feb '12

23 Feb '12

Hi Hans, can you add the following list alternative to strc-lst.mkvi \def\v!interactive{interactive} \definelistalternative [\v!interactive] [\c!renderingsetup=\??listrenderings:interactive] \startsetups[\??listrenderings:interactive] \edef\p_command{\listalternativeparameter\c!command}% \ifx\p_command\empty [\currentlist: \currentlistentrynumber\space -- \currentlistentrytitle\space -- \currentlistentrypagenumber]% \else \listparameter\c!before \hbox \strc_lists_get_reference_attribute\v!all \strc_lists_get_destination_attribute { \p_command\currentlistentrynumber\currentlistentrytitle\currentlistentrypagenumber } \listparameter\c!after \fi \stopsetups This is “alternative=command” with hyperlink functionality, I know “horizontal” and “vertical” do the same when a command is applied but I think this variant is better when no command is set.

Bugs: align[outer] requires setuppagenumbering, and fails on odd pages
by Sietse Brouwer 20 Feb '12

20 Feb '12

Dear devs, When I try to use \startalignment[outer], it fails when one of the following is true: * the command is invoked on an odd-numbered page, or * \setuppagenumbering[alternative=doublesided] was not called first. Regarding the second point, the bug is that I believe \setuplayout[location=doublesided] also ought to work, but doesn't. I get the same "! undefined control sequence" error message in all cases; the error message and a minimal *working* example are reproduced below, with comments showing how to break the working example.
