Wrong structure numbers in margin
by Marco 16 May '12

16 May '12

Hi Hans, could you check the definition of \placeheadmarginalternative in strc-ren.mkiv? The current solution fails when structure number are set to “margin” in a doublesided layout because of the hard-coded \leftmargindistance. The “maybe better” solution actually seems to work better. \setuplayout [backspace=8cm, width=5cm, leftmargindistance=2cm] \setuppagenumbering [alternative=doublesided] \setupheads [alternative=margin] \unexpanded\def\placeheadmarginalternative#1#2% {\vbox {\localheadsetup \begstrut % use one \strut here! \dontleavehmode % in case there is no strut, else side effects with llap \ifconditional\headshownumber % this gives a wrong result on the second page %\llap{\hbox{\hfill{#1}\hskip\localheadskip\hskip\leftmargindistance}}% introduces whitespace % maybe better: \inleftmargin{\hbox{\hss{#1}\hskip\localheadskip}}% \fi {#2}}} \showframe \starttext \chapter{Chapter} \null\page \section{Section} \subsection{Subsection} \subsubsection{Subsubsection} \stoptext Regards Marco Patzer

Streams: compensation not happening correctly.
by Sietse Brouwer 12 May '12

12 May '12

Hi all, I was trying to work out the streams mechanism, and found the following bug (I call my streams [left] and [right]): * An unwanted extra compensating line is inserted after the first block of the [left] stream that is as tall as, or shorter than, its corresponding block in the [right] stream. * If that extra line has not yet been inserted, then when two blocks have the same height the one on the [left] is wrongly measured as being shorter. (For a single line containing a capital A, it's 561512 vs 932551.) * This happens only once: subsequent identical-content blocks will indeed have identical heights. This is just a bug report; for me, at least, a fix is not required. Minimal example and relevant bit from its output log below.

Hi Hans, can you add this to page-brk.mkvi \installpagebreakmethod \v!left {\page_otr_flush_all_floats \page_otr_command_next_page_and_inserts \doifbothsidesoverruled{}{\resetcurrentstructuremarkswithpage\page_otr_insert_dummy_page}{}} There is a comment in the file % \installpagebreakmethod \v!left {} % defined in page-txt.mkiv to look at page-txt.mkvi for the method but it isn’t defined there.

\setuppapersize: mirrored, negative, rotated, etc. not working in mkiv
by Sietse Brouwer 25 Apr '12

25 Apr '12

Hi, While working on the wiki I discovered that mkiv fails on a few \setuppapersizes keys. Minimal example below. I'm using mkiv, 2012.04.19 23:18. mkii does it all with no problems. I discovered this while working out what the various keys do; I myself don't need a fix. --Sietse % negative causes an 'undefined control sequence' error. % So do mirrored, 90, 180, and 270. % rotated causes no error, but does nothing % \setuppapersize[A6][A5] % works \setuppapersize[A6,negative][A5] %fails \starttext asdf \stoptext

Bug in pgfplots module

Storing and retrieving two-pass data
by Marco 22 Apr '12

22 Apr '12

Hi, I am trying to save a string to the .tuc file and to retrieve it in the next run. My attempt: \starttext \startluacode local collected = utilities.storage.allocate() local tobesaved = utilities.storage.allocate() job.register("job.userdata", tobesaved) tobesaved["foo"] = "value_foo" tobesaved["bar"] = "value_bar" \stopluacode \stoptext This leads to the following entry in the .tuc file: utilitydata.job.userdata={ ["bar"]="value_bar", ["foo"]="value_foo", } I expected to be able to retrieve the data with e.g. collected["foo"], but the collected table is empty. What is the interface to retrieve the values from the .tuc file? Aditya mentioned that there will be a new interface in this (or the upcoming) beta. Marco

Spacebefore and spaceafter in strc-mat
by Aditya Mahajan 18 Apr '12

18 Apr '12

Hi, strc-mat sets: \def\beforedisplayspace {\doifnot{\formulaparameter\c!spacebefore}\v!none{\blank[\formulaparameter\c!spacebefore]}} \def\afterdisplayspace {\doifnot{\formulaparameter\c!spaceafter}\v!none{\blank[\formulaparameter\c!spaceafter ]}} Other environments that provide spacebefore and spaceafter keys (delimiters, floats), do not check if the key is none. I don't really understand why this check is done. Can we delete this check? Aditya

strc-ref.lua
by Wolfgang Schuster 13 Apr '12

13 Apr '12

Hi Hans, can you add the following filters to strc-ref.lua and I would remove “filters.text.number” because it’s nonsense when \getreference[number][…] delivers a string and not a number. filters.text = { } function filters.text.title(data) helpers.title(data.entries.text or "?",data.metadata) end -function filters.text.number(data) - helpers.title(data.entries.text or "?",data.metadata) -end function filters.text.page(data,prefixspec,pagespec) helpers.prefixpage(data,prefixspec,pagespec) end +filters.full = { } +filters.full.title = filters.text.title +filters.full.page = filters.text.page Wolfgang

\setuphead and conversion key

Hi Hans, shouldn’t the name of the “conversion” key be changed to “sectionconversion” because the other structure key have the names “sectionset”, “sectionstarter” etc. \setuphead[section][conversion=Characters] %\setuphead[section][sectionconversion=Characters] \starttext \section{The letter A} \stoptext Wolfgang
