tabulate inside itemize
by Mike Cooper 29 Jul '20

29 Jul '20

I would normally use tab stops and line breaks to achieve the following in a numbered list: 1. DC = 3.20 bbl = 420 ft HWDP = 3.90 bbl = 450 ft DP = 34.63 bbl = 2,037 ft Totals = 41.73 bbl = 2,907 ft 2. [next step …] This is what I tried, but the output has a blank line at the number. I can’t find anything about tabulate inside itemize. \starttext \startitemize[n] \startitem \starttabulate[|l|l|r|l|r|] \NC DC \NC = \NC 3.20 bbl \NC = \NC 420 ft \NC \NR \NC HWDP \NC = \NC 3.90 bbl \NC = \NC 450 ft \NC \NR \NC DP \NC = \NC 34.63 bbl \NC = \NC 2,037 ft \NC \NR \NC DC \NC = \NC 41.73 bbl \NC = \NC 2,907 ft \NC \NR \stoptabulate \stopitem \startitem Convert 2,907 to TVD: \\TVD = 2,907 × cosine 45° = 2,907 × 0.707 = 2,056 ft \stopitem \startitem ΔP = 2,056 ft × 0.052 × (15 - 7.2) = 834 psi \stopitemize \stoptext Is there some way to stop the blank line or should I use an entirely different approach?

no reference output for \namedstructurevariable
by Damien Thiriet 29 Jul '20

29 Jul '20

Hello, I am facing some issue with \usernamedvariable. Consider this MWE \starttext \startsection[title={Mammals and eggs},reference={mammals}] \namedstructurevariable{section}{title} \namedstructurevariable{section}{reference} and \currentstructurereference \stopsection \stoptext \namedstructurevariable{section}{reference} doesn't give any output, while \currentstructurereference does. Is this a bug or something I miss? I get also no output when I define custom key/value with startsection and call them with namedstructurevariable. Best regards, Damien Thiriet ----- End forwarded message -----

Height of parentheses in a matrix with lmtx

Hi Hans, With the upgraded version of lmtx, the parentheses of the matrix are no longer adjusted to the content. Thank you. Fabrice \definemathmatrix [pmatrix][matrix:parentheses][simplecommand=MATRIX] \starttext \math{\MATRIX{\MPcode{draw (0,0) -- (1cm,0);} ;\MPcode{draw (0,0) -- (1cm,0);} }} \stoptext

upload

Hi, Normally we don't report on successive loe level improvements in the engine or the core of context (we do so in articles and wrapups), and much goes unnoticed anyway (which is good). But ... the last couple of weeks we have been playing with some adapted functionality in lmtx and some of the experimental low level code has now made it in core. Normally users will not notice this but who knows. There are already features in lmtx that are not (and are unlikely to be) in mkiv (most significant in the metapost related part). When possible new macros and additions to mechanism will be in both mkiv and lmtx, but lmtx users will be better off in the end. We're mostly talking of the more tricky mechanisms here, those that currently have limitations due to all kind of possible interferences. To summarize: mkii : frozen (seldom patches) lmtx : cutting edge mkiv : when possible following lmtx, otherwise frozen Because we develop lmtx and luametatex alongside it is no problem if we have experimental (and even temporary imperfect) code in the engine: context knows about it and especially with experiments, we try to make sure it doesn't hit users (who we don't expect to use those, often undocumented, new tricks anyway). It's sometimes the only way to go forward (stepwise testing). So, here is an example of where lmtx can do better than mkiv: \placefigure[left]{}{} \input ward \par \placefigure[left]{}{} {\bf \input ward} \par Another area is in using footnotes. As a first step to more robust handling of deeply nested notes, lmtx now defaults to (the more than a decade optional in mkiv) \automigrateinserts, but with less overhead (for performance reasons, it was never enabled in mkiv, apart from occasional side effects). It is features like these that will stepwise be improved, at least that is what we hope for. So, the current upload has some new stuff, hopefully without too many side effects, but if so, we'll deal with it as usual. As a result, the latest lmtx could be a little slower, but I wonder if someone will notice it in practice.

question on page transitions
by Pablo Rodriguez 25 Jul '20

25 Jul '20

Dear list, I have a question about page transitions (lines 297-304 from scrn-pag.mkvi): \def\scrn_transitions_set_indeed {\begingroup \edef\currentinteractionscreendelay{\interactionscreenparameter\c!delay}% \clf_setpagetransition n {\scrn_transitions_list}% delay \ifx\currentinteractionscreendelay\v!none \zerocount\else\currentinteractionscreendelay\fi \relax \endgroup} I wonder whether the "delay" option in \setupinteractionscreen defines the number of seconds for the page or for the transition. From what I read in the code above, I would say that the duration is defined for the transition itself. Inspecting the output PDF code in generated documents, the duration is set for the page. In PDF code. /Page <</Duration 5>> sets the number of seconds for the page (https://www.adobe.com/content/dam/acom/en/devnet/pdf/PDF32000_2008.pdf#sear…) /Page <</Trans <</D 5>> >> sets the number of seconds for the transition (https://www.adobe.com/content/dam/acom/en/devnet/pdf/PDF32000_2008.pdf#name…) With the followling sample: \setuppapersize[A9,landscape] \setupinteraction[state=start] \setupinteractionscreen[option=max, delay=5] \setuppagetransitions[random] \setupbodyfont[50pt] \starttext \dorecurse{2}{% \startmakeup[page][style=\bf\ss, align=center] \recurselevel \stopmakeup% } \stoptext The output PDF document may contain a /Page object such as: 6 0 obj << /Contents 4 0 R /Dur 5 /Trans << /Di 90 /M /O /S /Fly >> /Type /Page >> endobj This forces the viewer to advance the page after 5s. To have a transition duration of 5s, it should read: 6 0 obj << /Contents 4 0 R /Trans << /D 5 /Di 90 /M /O /S /Fly >> /Type /Page >> endobj https://www.adobe.com/content/dam/acom/en/devnet/pdf/PDF32000_2008.pdf#name… shows the difference between /Dur and /D. Could anyone confirm whether this should be fixed (or I’m missing something)? Many thanks for your help, Pablo -- http://www.ousia.tk

Dear ConTeXt users, I have been trying to get the presentation effects listed here to work: https://wiki.contextgarden.net/Presentation_effects But I am unable to build the example. I am using the Debian ConTeXt (version 2020.03.10.20200331-1). Please let me know if I am missing something. Thanks. Kumar -- Kumar Appaiah

\documentvariable (used in environment)
by Alan Braslau 25 Jul '20

25 Jul '20

Hello, I have put the following in an environment \startenvironment MYENVIRONMENT \setupdocument [metadata:title={\documentvariable{title}}, metadata:subtitle={\documentvariable{subtitle}}, metadata:author={\documentvariable{author}}, metadata:keywords={\documentvariable{keywords}}] \stopenvironment and correct use would be \environment MYENVIRONMENT \startdocument [title={My title}] \stopdocument because, of course, the environment contains more than \setupdocument such as font loading that should be done before the \startdocument. The metadata does not get set properly, having to do with expansion or other notions of TeX that I never seem to get right. What might be the proper way of handling this? Thank you Alan

indentnext option for \setuplanguage?
by Pablo Rodriguez 23 Jul '20

23 Jul '20

Hans, as Garulfo mentioned in a previous message (https://mailman.ntg.nl’t /pipermail/ntg-context/2020/098826.html), French may require that all paragraphs are indented (no matter what comes before the paragraph). Spanish also requires that. How about a key for "indentnext" in \setuplanguage? That makes it easier to have documents that require all "indentnext" keys set to "yes". I don’t mean changing the default behaviour for any language. Could the "indentext" option be added to \setuplanguage? Pablo -- http://www.ousia.tk
