How to prevent moving figure on the next page?
by Dmitriy Tokarev 07 Aug '13

07 Aug '13

Hi list, I need help to undestand this effect: If setuphead[chapter][page=no] and after figure start a new chapter, than figure is moved to the page 2, although on page 1 space is enough. Thanks. \setuppapersize[A5][A5] \setupbodyfont[10pt] \setuphead[chapter][page=no] \showframe \starttext \chapter {One} \dorecurse{2}{\input{knuth}} \placefigure[here][figure]{Description} {\externalfigure[figure][width=5cm,height=2.0cm]} % if setuphead[chapter][page=no] and this comment transform to text, than figure moves to page 1. What do I need to figure always placing on page 1? \chapter {Two} \stoptext -- Dmitriy

kerning with buggy libertine
by Philipp Gesang 07 Aug '13

07 Aug '13

Hi Hans, this is a bug report thanks to Khaled: http://tex.stackexchange.com/a/126650/14066 In short: the font loader applies the kerning of libertine version 5.3.0 even though this appears to be broken in the font. Context translation of the example: \definefontfeature [kerning] [mode=node,smcp=yes,kern=yes] \definefont [libertineserifsmallcaps] [file:LinLibertine_R.otf*kerning] \definefont [libertinesanssmallcaps] [file:LinBiolinum_R.otf*kerning] \def\demotext{Vacillate Vaccine Vapour Vanish Va...} \starttext {\libertineserifsmallcaps \demotext}\par {\libertinesanssmallcaps \demotext}\par \stoptext (Doesn’t occur in base mode.) The technical details are in the thread Khaled references. Best regards, Philipp -- () ascii ribbon campaign - against html e-mail /\ www.asciiribbon.org - against proprietary attachments

Hi all, with LuaTeX, Version beta-0.77.0-2013073017 (rev 4639) and ConTeXt ver: 2013.08.06 15:50 MKIV beta fmt: 2013.8.7 int: english/english Context seems not to be able to typeset Labels anymore. Yesterday, before an Update, all worked as expected. Minimal not working example: \starttext \startMPpage draw fullcircle scaled 5cm withcolor red; label(textext("\CONTEXT"),origin); \stopMPpage \stoptext Or am I missing something happened in the last four weeks? Thanks Greetings Lutz

\completepublications in component creates wrong hyperlinks
by Marco Patzer 06 Aug '13

06 Aug '13

Hi, if a \completepublications call is used in a component, the hyperlink, which is supposed to link to the bibliography, instead links to a (probably non-existing) pdf file named after the component. \startbuffer [sample] @BOOK{Eijkhout1991, title = {\TeX\ by Topic. A \TeX nician's Reference}, publisher = {Addison-Wesley}, year = {1991}, author = {Victor Eijkhout}, address = {London}, keywords = {general}, } \stopbuffer \savebuffer [list=sample, file=bibliography.bib, prefix=no] \startbuffer [component] \startcomponent * \completepublications [criterium=text] \stopcomponent \stopbuffer \savebuffer [list=component, file=bib-component.tex, prefix=no] \setupinteraction [state=start] \setupbibtex [database=bibliography] \starttext Some text. \cite [Eijkhout1991] %% creates a hyperlink to bib-component.pdf \component bib-component %% this one works %% \completepublications [criterium=text] \stoptext Marco

\externalfigure doesn't find mps file in subdirectory
by Sanjoy Mahajan 06 Aug '13

06 Aug '13

\externalfigure won't find a metapost eps file in a subdirectory, if the mps has the numerical (.1) extension. Here's a minimal example (test.tex): \setupexternalfigures[directory={fig}] \starttext \externalfigure[simple.1] \stoptext where fig/simple.1 is from a simple .mp file that fills a 1-cm box (see below). The resulting test.pdf shows the gray box name : simple.1 file : simple.1 state: unknown Only this combination of circumstances triggers the problem. Giving the full path ("\externalfigure[fig/simple.1]") works fine, as does renaming the file to simple.mps (within the fig/ directory), as does using instead simple-1.pdf (made with mptopdf). Thus, I have several workarounds, but it might be useful to figure out what is not working. I've noticed this problem on and off for a while now, but only now made a minimal example. (Is the path-searching code trying to append extensions and directory prefixes at the same time, and thus not finding the file?) This is with MkIV 2013.05.28 from vanilla TL2013. For completeness, here's simple.1, although any file will show the problem equally well: %!PS %%BoundingBox: 0 0 29 29 %%HiResBoundingBox: 0 0 28.34645 28.34645 %%Creator: MetaPost 1.803 %%CreationDate: 2013.08.04:0841 %%Pages: 1 %%BeginProlog %%EndProlog %%Page: 1 1 0 0 0 setrgbcolor newpath 0 0 moveto 28.34645 0 lineto 28.34645 28.34645 lineto 0 28.34645 lineto closepath fill showpage %%EOF -Sanjoy

Hiding \part completely except for in the ToC
by Alexander van Ratingen 06 Aug '13

06 Aug '13

Hi everyone, I'm having a little problem and I'm hoping you can help. For my table of contents, I need to group my sections, but I don't want any heads for this in the text. Now, I've been using \part for this but unfortunately I cannot get rid of the empty space it leaves. The only way I've been able to get rid of the empty space is by setting: \setuphead[part][placehead=empty] But then it's not in the ToC either. Alternatively, when setting placehead to any other value, it still leaves an empty line in the text. Is it possible to have both, ie \part's in the ToC without any space taken by it in the text? Thanks for your time, Alexander

Passing macro parameters to lua
by Matt Gushee 05 Aug '13

05 Aug '13

Hello, good people-- I've encountered what appears to be a bug in either the TeX->Lua interface or the documentation thereof (I have the latest stable ConTeXt standalone from contextgarden.net) I'm trying to create a macro that will insert different text depending on whether one of the arguments is empty or not. My initial test implementation (following the wiki section entitled "Passing arguments and buffers: ConTeXt commands that hook into Lua") looked like this: \startluacode userdata = userdata or {} function userdata.empty_or_not(str) if str == "" or str == nil then context("{\\sc Empty}") else context(str) end end \stopluacode \def\emptyOrNot#1{% \ctxlua{userdata.empty_or_not(#1)}% } \starttext \emptyOrNot{Amazing Text!} \emptyOrNot{} \stoptext This did not work. I determined that even when I passed a non-empty string, the Lua interpreter detected it as nil. It turns out the fix was simple--I had to quote the string, as follows. \def\emptyOrNot#1{% \ctxlua{userdata.empty_or_not("#1")}% } It took me a while to figure that out, though, since the wiki example does not show quotes. -- Matt Gushee

Locating pdf files in the texmf directory structure
by Michael Ash 05 Aug '13

05 Aug '13

I asked: >> (4) Where can I put personal files that I would like context to use regularly. which Marco kindly answered: > In the directory TEXMFHOME points to or texmf-local. This works for my personal file env_letter.tex which is called with \environment env_letter.tex. This file env_letter.tex calls the letter module, sets some correspondenceparameters, etc. But env_letter.tex calls two pdf files with \externalfigure (see below). These two pdf files are also in the directory pointed to by TEXMFHOME but they show up in the finished document as gray "state: unknown" boxes Does this involve "tracking" as discussed in http://wiki.contextgarden.net/Command/externalfigure ? Thank you very much for guidance. best, Michael % Define logo for the first page header \defineletterelement[layer][head][example]{% \framed[background=logohead,frame=off,align=left]{% \externalfigure[UMA_Seal_200_Maroon.pdf][height=3.1cm]} } \setupletter[ signature={\externalfigure[signature-blue.pdf]} ]

[***SPAM***] Simple Context Application to Cards
by d.henman 05 Aug '13

05 Aug '13

This is a trivial appliation for Context, but a useful one. I plan on designed some business cards, but am new to Context. My idea to to have a logo image in the upper left hand corner, with the company name to the right of it. This would be two block elements at the top of the card. In the middle will be the name, and below that the address, tel, etc. -- Regarding the two blocks at the top of the card: Something like the below: logo here Company name here .--------------------------------------. | | | ooooo XYZ Printing Company | | ooooo | This top area is the subject of this mail. | ooooo Card Design & Services | ............................................. | | | | | First_Name Last_Name | All this below the ... line is done. | | | contact information | | | '--------------------------------------' I take this as two blocks aligned horizontally on the 91mm x 55mm card stock. >From my reading the Context options for doing this are: The margins are so small that using \inmarge{\externalfigure[company-logo][width=\marginwidth] } can not work. Which option should I pursue? a.) \startcombination ... \externalfigure + text block \stopcombination a.) \placefigurehere[... force] \startcombination ... \externalfigure + text block \stopcombination c.) \startfiguretext ... \stopfiguretext d.) some other Context mechanism. Any advice is appreciated. Thanks
