columnsets
by Hans Hagen 09 Feb '16

09 Feb '16

Hi, I'm currently reimplementing columnsets and I'm wondering how many users there are of this mechanism. How bad is it if the more obscure features go away and others show up.

Hello, the following code: ---- \usemodule[pgfplots] \starttext aaa \stoptext ---- fails with: " close source > 1 > 16 > d:/Ctx-Beta/tex/texmf-context/tex/context/base/mkiv/cont-yes.mkiv tex error > tex error on line 0 in file : !

Lost in letter module
by Jan U. Hasecke 09 Feb '16

09 Feb '16

Hi all, I am completely lost in the letter module. I started with the tutorial "Correspondence with ConTEXt Version: 2010.08.27" but reference line does not show up at all. So I read a little further: http://wiki.contextgarden.net/Letter And the PDFs that are linked under "Further information" But I fear that I am now completely lost as some commands seems to be old or deprecated or whatever, but they simply does not work. And there are references to new commands in the text. What I am trying to get is a letter with first and second page style, where on the first page I need a special foot with accounting infos etc. Including a background file (uncommented in the mwe) works fine. I need a references line for customer id, invoice id and date just above the subject. I don't understand the setupletterlayer command as you can see in the mwe where I use a negative value for x to push it to the right position. I have no idea how x and y are working and what position is for. The same is true for \setupletterframe. I am using: Version beta-0.89.0 (TeX Live 2016/dev Here is my mwe: \mainlanguage[de] \usemodule[letter] \useletterstyle{dinb} \setupletteroptions [%backgroundimage=/home/juh/Bilder/Diverses/Hintergrund.png, language=german] \defineletterelement[layer][reference][rechnung] {Kundennummer: \correspondenceparameter{kd} \| Rechnungnummer: \correspondenceparameter{id}} \setupletterlayer[reference] [ alternative=rechnung, style=\tfx\sans,y=10pt, x=-63mm, y=100mm, position=topleft] \setupletterframe[reference][align=left] \setupletter [toname={Mustermann GmbH\\Peter Mustermann}, toaddress={Haubenweg 3\\12345 Musterstadt}, signature={Jan Ulrich Hasecke}, date=\currentdate, kd={077}, id={2016002}] \starttext \startletter [opening={Sehr geehrte Damen und Herren}, closing={Mit freundlichen Grüßen}, subject={Imagebroschüre Mustermann GmbH}] Hiermit berechne ich Ihnen 100 € für Leistungen. \stopletter \stoptext

numbering problem
by dr. Hans van der Meer 09 Feb '16

09 Feb '16

The following problem in the numbering of equations, figures, tables has arisen. For the subdivison of the document is wanted the numbering scheme chapter (numbered) section (numbered) subsection (numbered} subsubsection (not numbered) Doing this with \setuphead[subsubsection][number=no], because I find 3 levels of numbering enough. However, the number=no on the last \setuphead has as sideeffect that the chapternumber is missing on equations, figures, tables. Thus for example instead of "table 1.4" I am seeing "Table 4". How can I keep the numbering at 3 levels instead of 4 in still have tables inside subsubsections numbered as "Table 1.4"? Hans van der Meer

Primitive angle (Metapost)

Hello, I want to reproduce this figure. In the example below, it seemed to me that he had to write dir(180-angle(1,0.5)), but not. \starttext \startMPcode path p ; p := (3.5cm,-1.5cm)--(0cm,0.25cm)--1.2cm*dir(180-angle(1,0.5)) ; draw p dashed evenly withcolor 0.625white; draw p reflectedabout ((3.75cm,-1.5cm),(3.75cm,1.5cm)) dashed evenly withcolor 0.625white ; draw (-1cm,-1.5cm)--(8.5cm,-1.5cm)--(8.5cm,0.9cm)--(-1cm,0.9cm)--cycle withcolor 0.625white ; for i=0 upto 14 : draw unitsquare scaled 0.5cm shifted(i/2*cm,0*cm) ; endfor ; for i=0 upto 10 : draw unitsquare scaled 0.5cm shifted((i+2)/2*cm,-1/2*cm) ; endfor ; for i=0 upto 6 : draw unitsquare scaled 0.5cm shifted((i+4)/2*cm,-1*cm) ; endfor ; for i=0 upto 2 : draw unitsquare scaled 0.5cm shifted((i+6)/2*cm,-3/2*cm) ; endfor ; \stopMPcode \stoptext Thank you.

macro expansion inside a block
by Andrea De Michele 08 Feb '16

08 Feb '16

Hi all, I want to expand a macro inside a block when the block is written and not when it is used. Here a simple example: \defineblock[myblock] \hideblocks[myblock] \starttext \define\mynumber{1} Some text: mynumber is :\mynumber \beginmyblock This is mynumber inside the first myblock, I want 1 and I obtain: \mynumber \endmyblock \define\mynumber{2} Some text: mynumber now is :\mynumber \beginmyblock This is mynumber inside the second myblock, I want 2 and I obtain: \mynumber \endmyblock \useblocks[myblock] \stoptext This produce: Some text: mynumber is :1 Some text: mynumber now is :2 This is mynumber inside the first myblock, I want 1 and I obtain: 2 This is mynumber inside the second myblock, I want 2 and I obtain: 2 instead I want: Some text: mynumber is :1 Some text: mynumber now is :2 This is mynumber inside the first myblock, I want 1 and I obtain: 1 This is mynumber inside the second myblock, I want 2 and I obtain: 2 It is possible in some way? -- Andrea De Michele

Hyphenation of chemical names
by Alan BRASLAU 07 Feb '16

07 Feb '16

ConTeXt has troubles hyphenating chemical names, which in organic chemistry can be funny things such as N-(4-n-alkoxybenzylidene)-4’-alkylaniline. The names can get much worse... The rules for hyphenating in chemistry are well defined. Without putting specific hyphenating hints into the names themselves, I do not know how to go about adding these rules into ConTeXt. Of course, they can differ slightly by language, but the system is pretty much the same. Does anyone know how to deal with this? Maybe we need special rules that get applied within \chemical{}? Alan

06 Feb '16

============================================================== Luatex Release 0.89.0 was released 2016020500 ============================================================== No fundamental changes, just some fixes / improvements (and of course new bugglets). - New backend things: \pdfvariable pkfixeddpi = integer % > 0 : use only default dpi (so one can do with one high res instance) \pdfvariable ignoreunknownimages = integer % > 0 : ignore missing and inject something empty (to be used with care) and one can do this: \edef\foo{\pdfvariable foo} \def \oof{foo} \ifx\foo\oof don't fool me\fi (side effect of no longer aborting on missing, so one implement a catch) As usual, the archives can be downloaded from supelec: https://foundry.supelec.fr/projects/luatex/ You could also check out the sources via anonymous svn: svn co --username anonsvn --password anonsvn \ https://foundry.supelec.fr/svn/luatex/tags/beta-0.87.0 Bugs and feature requests can be added to the issue tracker at http://tracker.luatex.org When you use context or latex you need an updated format. The latest version of context can be fetched from the context garden, latex from ctan. For latex you can contact David and Joseph as they are dealing with the update. Have fun, Hans, Luigi, Taco

Supported architectures for minimals (any ppc users out there?)
by Mojca Miklavec 06 Feb '16

06 Feb '16

Hi, I would suggest dropping support for linux-ppc for the ConTeXt distribution unless somebody objects. I'm surprised about the number of ppc users on Mac (and would be curious to get more off-list feedback from those still using it). TeX Live planned to drop support this year, but it seems that it's staying for now. We are currently cross-compiling the binaries, but at the moment both luajittex and metapost compilations seem to be broken. We also don't seem to have any kfreebsd or sparc-solaris users, but as long as their builders enjoy supplying the binaries, that's fine by me ;) On the other hand I need to sit down one day and fix support for cygwin. I'm sorry that this didn't happen yet. Mojca

box'es do not spread out
by Meer, Hans van der 05 Feb '16

05 Feb '16

I am struggling with the following problem: Collect a number of boxes with: \global\setbox\placexcontent=\hbox{% \box\placexcontent % collection of previous boxes \box\placexbox % next box affixed to previous onse \hskip\placexdistanceskip % spearation, replacing by \hfill does not solve problem }% Thus the incoming \placexbox'es are strung together separated by a skip. Later they are typeset centered as a whole with: \hbox to\textwidth{% % will be wider than the sum of the original box collection \hss \box\placexcontent % or \unhbox, doesn't look different \unskip % unskip removes the last (extra) \hskip \hss % should succumb to \hskip 0pt plus1fill }% The problem is the following: (1) \placexdistanceskip=10pt boxes are separated neatly (2) \placexdistanceskip=0pt plus1fill BOXES DO NOT SPREAD OUT AS I EXPECTED THEM TO DO The flexible component does sadly not carry over to the final box, apparently. Clearly my misunderstanding of working with boxes. Can this be solved easily? Hans van der Meer
