Verbatim / prettyprinting in mkIV
by Matthijs Kooijman 08 Jun '09

08 Jun '09

Hi all, I've been struggling with verbatim printing in MkIV for a while now and found some confusing things. I did finally get things working, but after quite some effort. I'd like to hear if my conclusions are correct, perhaps I can put them on the wiki then. I was trying to set up some custom pretty printing scripts, using lua (since I'd rather not learn complete tex scripting :-p). Looking at the files in /usr/share/texmf/tex/context/base and the wiki (Verbatim_text talks about verb-foo.tex files), I created a file called verb-foo.lua. I put this beside my document at first, and then in /usr/share/texmf/tex/context/base when it did not work, but neither worked. I tried setting things up as follows: \installprettytype [FOO] [FOO] \definetyping[FOO][option=FOO] \startFOO blub \stopFOO Trying to trace the code, I worked out things should work as follows: \installprettytype sets the "evalue" \??ty\??tyFOO to point at FOO \definetyping call \setupprettiesintypeFOO, which finds looks up the above evalue, finds FOO and then turns that into verb-foo and calls \ctxloadluafile{verb-foo}{}. This sets up the buffers.visualizers.foo value in lua. When actually starting a typing environment, dodotypeA or dodotypeD call buffers.hooks.flush_line, which in turn calls buffers.visualizers.foo.flush_line. The above didn't happen for me, so I tried manually loading the lua file using \ctxloadluafile{verb-foo}{}. After this, things started working for some reason. When looking closer and installing some \writestatus lines in core-ver.mkiv, I found that \setupprettiesintype was never actually called! Closer inspection showed that the entire core-ver.mkiv is never loaded when running "context --make". However, there is a second file, buff-ver.mkiv which closely resembles core-ver.mkiv and which is loaded. An important difference, however, is that buff-ver loads pret-foo instead of verb-foo (or rather, uses the value of \f!prettyprefix, which is set to "pret-" in mult-sys.tex). Renaming my lua file to pret-foo.lua made context find it exactly as it should, also when putting the file next to the main document. So, my main question was, are the verb-*.lua and core-ver.text files still used in any way? I just checked the minimals tree, and found out they have been removed already (but I didn't have -d in my rsync commandline to actually remove them). Looking at the previous version I was running (2009.05.20 beta) it seems that this change was actually pretty recent, so I mostly created this confusing situation by upgrading today (because my verbatim file was not properly loaded). I'm not so sure why it was not working before then, but at least it is working now. Heh, this is what you get when you write an email while you are still trying things out. All this buildup to get to a question, when the question is not even relevant. As for another relevant question: Is my analysis of how things are supposed to work correct? Then I might put something like it on the wiki. Also, it seems that \ctxloadluafile does not give an error when the file was not found. If it would have, things would probably have been a lot easier. Is there any compelling reason to make it fail silently? Gr. Matthijs

TexPaste alpha - my Win application converting Word/HTML to TeX
by Vyatcheslav Yatskovsky 08 Jun '09

08 Jun '09

Hello, I'm glad to report that I made a simple application (sorry, only forWindows at the moment) that coverts text from Ms Word (or other editors) or HTML pages (web sites) into TeX. DOWNLOAD LINK (280 KB): http://ul.to/hmpy60 The app recognizes at the moment only following formats/tags: Bold (<b>), Italic (<i>), Header 1 (<h1>), Header 2 (<h2>), Header 3 (<h3>). It coverts NOBREAK_SPACE (A0) into ~, &nbsp into \enskip, " into ", & into \&, and < > into < >. It is UTF-8 ready. USAGE: copy desired text fragment from Word or web page into clipboard, and click big "Get..." button and see the result in the bottom field. Click "Copy Result" to get TeX-formatted text back into the clipboard, and paste it into your editor. KNOW ISSUES: Some crap from Word formatting like  tags happens to leak, but it is easier at the moment to delete it manually. And sorry... awful interface. It is very-very first alpha, I want to show it just as proof-of-concept and to get some feedback. Actually, I did it for myself to simplyfy conversion from Word into TeX. I have some documents to be converted (e.g., lecture notes), and this happens to be easy task with my tool :). Best, Vyatcheslav

Can't set typescript
by Maurício 07 Jun '09

07 Jun '09

I'm trying this small test: %%%%% \enableregime[utf] \usetypescriptfile[type-xtx] \usetypescript[gentium] \setupbodyfont[gentium] \starttext \showbodyfont \stoptext %%%%% It's supposed to select 'gentium' as typeface, but the chart shown by 'showbodyfont' says I'm using 'modern'. Am I missing something? I'm using minimal install, updated yesterday (although I have this problem for at least two weeks). Thanks, Maurício

labels and new structure code
by Thomas A. Schmitz 07 Jun '09

07 Jun '09

Hi all, Hans, here is a bug that remains with the new structure code after Hans fixed many things two weeks ago. I want a counter that is reset at every odd chapter. This works as expected in mkii (and used to work in mkiv), but complains about a "Missing number, treated as zero" and fails to compile in current beta: \setupcolors[state=start] \setuphead [section] [command={{\determineheadnumber[section]}\ifodd\currentheadnumber \resetSlideNumber\incrementSlideNumber \else\incrementSlideNumber \fi}, expansion=yes] \definelabel[SlideNumber][headstyle=normal,way=bytext] \define\SLN{\color[red]{ [\nextSlideNumber]}} \starttext \section{One} should be 2: \SLN \section{Two} should be 4: \SLN \section{Three} should be 2 again: \SLN \section{Four} should be 4 again: \SLN \stoptext Even if you comment out the command=... line, you'll see that labels in mkiv still don't quite do what they should. All best Thomas

Crop marks and \setuplayout[nx,ny]
by Nicolas Girard 07 Jun '09

07 Jun '09

Hi, the following code, which I ran with context --mode=print shows crop marks in the middle if the sheet, overlapping the pages. It is legitimate to specify dy=0pt in order to minimize paper cuts. It seems to me like, in the case when dy=0pt, the code dealing with crop marks should try not to overlap the pages, or suppress the marks between two columns of pages. What do you think ? Is there currently a solution to this ? Cheers, Nicolas ============ \definepapersize[BC][width=85mm,height=54mm] \definelayer[blocks][width=85mm,height=54mm] \doifmodeelse{print}{ \setuppapersize[BC][A4] \setuplayout[nx=2,ny=5,dx=1cm,dy=0pt] \setuplayout[location=middle,width=fit,height=fit,marking=on] }{ \setuppapersize[BC][BC] \showframe[edge] } \setuppagenumbering[location=,state=stop] \def\ZapfinoMedium{} \def\ZapfinoBig{} \setupbackgrounds[page][background=blocks] \starttext \startstandardmakeup \setlayer[blocks][preset=rightbottom]{% \externalfigure[g-wurf][height=4.7cm]} \setlayer[blocks][preset=middletop,voffset=1mm]% {\ZapfinoMedium Title} \startbuffer \vbox{% \startlines Some Names of Some Cats \vskip-3pt\tfx smaller \vskip-5pt text \stoplines} \stopbuffer \setlayer[blocks][voffset=1.5cm,hoffset=2mm]{\getbuffer} \startbuffer \vbox{% Name and\hfill\break Address }% \stopbuffer \setlayer[blocks][preset=leftbottom,offset=1.5mm,hoffset=0.5mm]{\getbuffer} \setlayer[blocks][preset=rightbottom,offset=1.5mm]{www.samtfeld.de} \stopstandardmakeup \stoptext

3D PDF support (AKA asymptote support)
by Michail Vidiassov 07 Jun '09

07 Jun '09

Dear Hans, Mojca and All, a draft for an analog of LaTeX movie15 package for including Adobe Reader compatible 3d models into PDF files is at http://www.iaas.msu.ru/tmp/movie15context.tgz . Almost no docs/comments inside, but questions are of course welcome. You'd better take a brief look at part 5.2 of movie15 docs http://www.ctan.org/tex-archive/macros/latex/contrib/movie15/doc/movie15.pdf and part 13.6 of ISO/Adobe PDF spec http://www.adobe.com/devnet/acrobat/pdfs/PDF32000_2008.pdf to understand what are the settings. Since I lack understanding of ConTeXt/luatex combo and have to pass data for dictionaries containing other dictionaries to 3D model embedder I had to abuse two existing parameters, "control" and "display" and rely on sane lua code being put there. And even the limited parameter correctness checks do not report problems, they just silently fail to execute. One more option to deal with 3D models is not to embed them as annotations in the main PDF file, but to make a PDF with only 3D model in it and attach it to the main PDF, linking to a clickable 2D image (like attachfile2 LaTeX package). Donno if that functionality is in working condition now and how to use it. Sincerely, Michail

Bug in mkiv math mode: missing \longrightarrow
by Otared Kavian 07 Jun '09

07 Jun '09

Hi Hans, Testing your last night's beta, LuaTeX, Version beta-0.40.1-2009050813 (Web2C 7.5.7) ConTeXt ver: 2009.06.04 22:20 MKIV fmt: 2009.6.4 int: english/ english I noticed that \longrightarrow is missing in mkiv, while everything is correct in mkii. Here is a minimal example: %%% begin example \starttext Consider a continuous function $f : (0,1) \longrightarrow E$, where $E $ is a Banach space, as above. Consider a continuous function $f : (0,1) \rightarrow E$, where $E$ is a Banach space, as above. \stoptext %%% end example In mkiv nothing appears for \longrightarrow, although the typesetting goes through. Thanks for your attention: OK
