\startframed and parameters
by Wolfgang Schuster 17 May '12

17 May '12

Hi Hans, \startframed doesn’t accept local settings because \pack_framed_process expects two arguments. Here is only one optional argument \unexpanded\def\startframed {\dosingleempty\pack_framed_start_framed} \def\pack_framed_start_framed[#1]% {\bgroup \advance\framednesting\plusone \expandafter\let\csname\??ol:\the\framednesting\s!parent\endcsname\??ol \pack_framed_process[\??ol:\the\framednesting][#1]% \bgroup} while \framed accepts two \unexpanded\def\framed {\bgroup \advance\framednesting\plusone \expandafter\let\csname\??ol:\the\framednesting\s!parent\endcsname\??ol \dodoubleempty\pack_framed_process[\??ol:\the\framednesting]} and \pack_framed_process checks for the second argument: \unexpanded\def\pack_framed_process[#1][#2]% assumes a \dodoubleempty (slows down), also should have leading \bgroup {\bgroup \pack_framed_initialize{#1}% \ifsecondargument % faster \getparameters[\currentframed][#2]% here ! \fi \pack_framed_process_indeed} Test file: \starttext \secondargumentfalse % was true from a previous command but should be false \startframed[frame=off]text\stopframed \framed[frame=off]{text} \stoptext Wolfgang

It depends on how much support you want. - for basic language support we need an entry in lang-def.mkiv - for labels we need entries in lang-txt.lua - for patterns you need to check with Mojca what file we need to use - if you also want commanda and keywords in esperanto we need to extend mult-def.lua Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | voip: 087 875 68 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------

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.

\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
