\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

How to update context modules; thank you, write-up, and a couple of questions
by Michael Ash 04 Aug '13

04 Aug '13

> I asked how to update context modules. Thank you very much to Marco for guidance, and I would like to write up how I used his advice to update a module without first-setup.sh. (I use a ubuntu/PPA installation of context and hence don't use first-setup.sh, which would make updating easy). 1. I downloaded the current version of the module (letter; http://modules.contextgarden.net/dl/t-letter-2013.07.31.zip in this case) from http://modules.contextgarden.net/ 2. I already have a personal /home/me/texmf directory (or would have created it). I put the zipped module update in this directory and unzipped it preserving the subdirectory structure. 3. I set the environment variable TEXMFHOME to my personal texmf directory ("export TEXMFHOME=/home/me/texmf") 4. I ran "mtxrun --script update --modules=letter" to tell context where to look for the new version of the letter module. I could now tell from the output that the updated version of the letter module was installed, and I also confirmed from the log file: resolvers > modules > 'letter' is loaded interface > macros > processed mkvi file '/home/me/texmf/tex/context/third/letter/base/s-cor-01.mkvi', delta 36 interface > macros > processed mkvi file '/home/me/texmf/tex/context/third/letter/base/s-cor-01.mkvi', delta 0 (before the update, the lines above read /usr/share/texmf... instead of /home/me/texmf...) I hope that this write-up is helpful to others. Please feel free to comment or amend if I've misunderstood. I have several questions: (1) Is it possible to tell which version of a module is installed, i.e., that I am using the 2013.07.31 version of letter? (The version of context appears in the log file but not the version of the module.) (2) After I update of the entire context installation, how will I tell context to again use the /usr/share/texmf version instead of the personal version? (3) Could I have done this installation into /usr/share/texmf and used "sudo mtxrun..." to make the updated module work on a multi-user system? (4) Where can I put personal files that I would like context to use regularly. For example I have three personal files: "env_letter.tex" which I include with "\environment env_letter"; a pdf file with my logo; and a pdf file with a scan of my signature. Is there a standard directory to hold such files, and how do I let context know where to find them, for example, with mtxrun? (It seems like a waste to copy them to a new location every time I want to write a letter). Thank you very much. Yours, Michael
