Vertical rules in multiple column mode
by Procházka Lukáš Ing. - Pontex s. r. o. 24 Jan '11

24 Jan '11

Hello, the following code generates 3column pages: --- \starttext \startcolumns[n=3,rule=on] \dorecurse{5}{\section{\recurselevel}\input knuth} \stopcolumns \stoptext --- You can see that the vertical bars on the page 1 don't reach the "real" bottom of the "text height", whilst they do on the next page. It seems that the length (or "range") of the vertical bar is given by the height of the FIRST column. It seems to me that the rule height should rather be given as (or related to): 1) MAXIMUM of height of all columns 2) or height of i-th rule as maximum of height of i- and (i+1)-th column (each two ADJACENT columns). Is there a way how to effect this? Best regards, Lukas -- Ing. Lukáš Procházka [mailto:LPr@pontex.cz] Pontex s. r. o.

Downloading long urls
by Aditya Mahajan 24 Jan '11

24 Jan '11

Hi, While downloading urls, context santizes the filename but does not check the length of the url. So, one can end up with a situation where the filename is too long for the operating system to handle. For example, the following fails on 32bit linux. \enabletrackers[resolvers.schemes] \startluacode local report_webfilter = logs.new("thirddata.webfilter") local url = "http://www.bing.com/search?q=Areallyreallylongstringjusttoseehowthingsworko…" local specification = resolvers.splitmethod(url) local file = resolvers.finders['http'](specification) or "" if file and file ~= "" then report_webfilter("saving file %s", file) else report_webfilter("download failed") end \stopluacode \normalend Is there a robust way to avoid this problem? One possibility is that in data-sch.lua instead of local cleanname = gsub(original,"[^%a%d%.]+","-") use local cleanname = md5sum(original) What do you think? Aditya

Forming paragraphs
by Procházka Lukáš 23 Jan '11

23 Jan '11

Hello, I would need to form paragraphs to such a shape: Abc defhi jklm nop qrst uvw xyz. ABCDE FGHIJKL MNOPQR STUW XYZ. Abc defhi jklm nop qrst uvw xyz. ABCDE FGHIJKL MNOPQR STUW XYZ. Abc defhi jklm nop qrst uvw xyz. ABCDE FGHIJKL MNOPQR STUW XYZ. <-- \textwidth ---------->| I.e. paragraphs whose first lines are always \textwidth in width and whose next lines are always somehow indented. I achieved the desired shape by the following combination of \setupnarrower and \setupindenting: --- \starttext \setupnarrower[left=2em] \startnarrower[1*left,0*right] \setupindenting[yes,-2em] \input knuth \stopnarrower \stoptext --- But I would like to ask whether this way is "clean" enough and/or there is a better way, especially via a kind of \setup<something> command, e.g. something like: \setupparagraph[MySpecialParagraph][first=0pt,next=2em] ... \startparagraph[MySpecialParagraph] Abc defhi jklm nop qrst uvw xyz. ABCDE FGHIJKL MNOPQR STUW XYZ. \stopparagraph % or: \startMySpecialParagraph Abc defhi jklm nop qrst uvw xyz. ABCDE FGHIJKL MNOPQR STUW XYZ. \stopMySpecialParagraph Kind regards, Lukas

Endnote-problem
by Robert Blackstone 22 Jan '11

22 Jan '11

Dear list, While preparing a contribution for a conference proceedings I encountered a weird problem that I don't know how to tackle: First, the editor wants endnotes, no footnotes. So I collected all "footnotes" in a separate section at the end (\subject{Notes} \placefootnotes). That works in principle. The paper contains several longish quotations in both the original language and in English translation. The editor wants the original text in the endnotes. So I put them there, in blockquotes. Works too, in principle. However, this results in more than one page of notes. But here ConTeXt, neither mkii nor mkiv, does not insert a page break. Instead it tries to place everything on one page, ignoring the layoout below the header. The result is that only half of the notes turn up in the pdf. The rest is cut off. After the truncated list of notes there follows an empty page. What can I do about it? Thanks in advance for any help. Regards, Robert Blackstone

escape in verbatim text eats line breaks
by Stefan Müller 21 Jan '11

21 Jan '11

Hi list, there seems to be something wrong with the "escape" mechanism in verbatim. Line breaks before escaped code are ignored. Consider the following example from the wiki [1] (e.g. the second line is printed right behind the first with no line break): \starttext \setuptyping[TEX][escape=yes] \startTEX /BTEX\em sometex/ETEX /BTEX\em sometex/ETEX \after \before /BTEX\em sometex/ETEX \before /BTEX\em sometex/ETEX \after \before /BTEX\em sometex/ETEX \inbetween /BTEX\em sometex/ETEX \after \before \after \stopTEX \setuptyping[TEX][escape={[[,]]}] \startTEX [[\em sometex]] [[\em sometex]] \after \before [[\em sometex]] \before [[\em sometex]] \after \before [[\em sometex]] \inbetween [[\em sometex]] \after \before \after \stopTEX \setuptyping[TEX][escape=//] \startTEX //\em sometex \before //\em sometex \stopTEX \stoptext Is this a bug or am I missing something here? Also "\setuptyping[TEX][escape=//]" seems to have no effect at all, "//" is printed just like normal chars. Best regards, Stefan Müller.

Re: [NTG-context] \getscaledglyph

Hi Thomas, I had to do some work with regard to this issue recently. What was mentioned on this list, is, that \fontchar is a command which will stay. \setupbodyfont[Myfont,rm,12pt] \definesymbol[Q.alt] [\fontchar{Q.alt}] \def\Qa{\symbol[Q.alt]} The easiest way to get a stable environment is to use the char-names from the font. You can extract a table with all char-names with \usemodule[fnt-10] \setupbodyfont[Myfont,rm,12pt] \starttext \ShowCompleteFont{Myfont.otf}{10pt}{1} % fontname, size,columns % \ShowAllGlyphs {Myfont}{48pt}{4} % fontname, size,columns \stoptext Kind regards Willi On 20 Jan 2011, at 08:51, Thomas Floeren wrote: > Hi, > > I did a rather huge update step from my working context 2010.09.29 to the actual beta.

Translating PDF-files
by Cecil Westerhof 20 Jan '11

20 Jan '11

Properly not really a ConTeXt question, but maybe nows the answer. Someone asked me how to convert a PDF to XML and back. The reasons is that he has a PDF in English, but he likes to have it also in Russian. His idea is to convert the PDF file to XML, translate the XML file with GoogleTranslate and convert the translated XML file to PDF. He asked me how to do this. Of-course it does not have to be a XML file, if GoogleTranslate can work with a TEX file, there is no reason not to do it. Does anyone know how to do this, or has pointers about how to do this? -- Cecil Westerhof

\hangaround in xml mkiv
by R. Ermers 19 Jan '11

19 Jan '11

Dear All, I am processing a docbook xml file, which works great (thanks to Wolfgang's introduction to TEI). I have some images and I want the text before and after them to wrap around. This can be achieved through the command \starthangaround .. \stoparound. Since the text that is to wrap around must be put between commands, I cannot attach the image to the figure/graphic tags that are within that text. The figure tag does not allow the para tag to be inserted, nor do other approprate media tags. Instead I attached them to the attribute 'role' of the para tag: <para role="dolce1">abcdef abcef</para> In the environment file I specified this: \xmlsetsetup{#1}{//para[@role]}{xml:chapter:para:role} The hangaround environment is put in the accompanying startxmlsetups: \startxmlsetups xml:chapter:para:role \starthangaround{\externalfigure[\xmlatt{#1}{role}]} \xmlflush{#1} \stophangaround \stopxmlsetups I also added an \xmlflush, assuming that the text itself is processed there. In a rough sense this works. There is a white angle in the text for the image. However, the image itself slides away. I am not sure what is going wrong. Has anybody got a clue? Thanks! Regards, Robert

new tikz terminal for gnuplot
by Mojca Miklavec 19 Jan '11

19 Jan '11

Dear gnuplot lovers, Peter Hedwig is soon going to submit a patch to gnuplot that fully supports ConTeXt via TikZ output. Its advantage over ConTeXt terminal is that one won't need to recompile gnuplot in order to be able to use it (the gnuplot team at least accepted TikZ terminal if they didn't accept the one for ConTeXt) which is great news. I need to fix some tiny bits before I upload a new version to ConTeXt modules (however the files are here: https://github.com/mojca/context-gnuplot) I can also commit changes done by Peter to https://github.com/mojca/gnuplot if they won't be added any time soon (but if anyone else wants to test it, feel free to ask for the files). An example of usage follows below. Here's his message (the comment about TeX Live is related to the long-standing bug in TikZ for ConTeXt; I'm just thinking about uploading a patch for TikZ to TLContrib ...): I am sorry, that it stalled a bit, but I worked on it secretly ;) But now I think it is time to release what is done so far to anyone who is willing to test it. Here is a brief list of changes to the gnuplot CVS version: * support for ConTeXt and plain TeX * removed dependencies for LaTeX packages other than TikZ * needs TikZ Version >= 2.0 * better support for saving terminal options with gnuplot 'save' command * fixed "overflow" on negative coordinates that are outside of the crop box * merged all recent patched from murphy-md and Ethan Unfortunately it is the Context output that does not compile with the most recent Context version I installed from TeXLive 2010 and the http://tlcontrib.metatex.org/2010/ repository. But I remember it working with an older version so I hope this can be fixed easily ...

Conditional cross references to floats
by Robert Blackstone 17 Jan '11

17 Jan '11

Hi all, I wonder if it is already possible to perform the following task: I have to typeset documents that contain many pictures of various sizes. Due to lack of space, some may pictures may not appear on the page on which they are discussed. And also in the course of revising the document, adding text may push them to another page. Therefore I always refer to every picture with \in and \at. On the other hand, changing or deleting text may unexpectedly land them on the correct page. So sometimes it may happen that the reader, for instance on page 23, will be referred to a figure on page 23, which looks rather silly. Is there a trick to let ConTeXt automatically omit the reference when the picture happens to appear on the correct page (or change the reference to « on this page »). In other words, can one make a sort of conditional reference that only mentions the page if it is not the present page? Would this perhaps be something that can be coded in Lua? (I saw a similar question on this list in june 2010, and the provisional solution that was suggested, but apparently did not work.) Incidentally, the address for the archive seems not to be correct (and untrusted). (Message: The requested URL https://foundry.supelec.fr/projects/contextrev/ was not found on this server.) If it is no longer in use wouldn't it perhaps be better not to mention it anymore at the bottom of each ntg-context Digest? Thanks in advance. Robert Blackstone

searchable PDF with MinionPro under mkiv

How can I generate a searchable PDF with mkiv, using a non standard font like MinionPro? \definefontfeature [default] [default] [mode=node,script=latn,onum=yes] \usemodule[simplefonts] \setmainfont[minionpro] \starttext fi ff ffi ffl 1234567890 \stoptext Using pdftotext, I get this: ﬁ ﬀ ﬃ ﬄ  However, using Adobe Reader this things won't be found.

\startquotation, grid and footnote
by Oliver Heins 17 Jan '11

17 Jan '11

Hello, I have to typeset paragraphed quotations in a smaller font (and maybe a smaller baselineskip, but this is not necessary) and with larger margins. However, after the quotation, the main text has to be on the grid again. Main Text Main Text Main Text (on grid) Main Text Main Text Main Text (on grid) Main Text Main Text quotation text (need not to be on grid, in a smaller font) quotation text Main Text Main Text Main Text (on grid) Main Text Main Text Main Text (on grid) Main Text Main Text I tried to use contexts quotation-mechanism, but it puts quotationmarks around the quotation, which is not only unnecessary (as the smaller font size marks the paragraph as a quotation already), but a problem, because footnotemarks appear right in front of the ending quotation mark (»quot¹« instead of »quot«¹, which would be right). Footnotes seem to be a bigger problem. When using the linecorrection mechanism (either with \start|\stoplinecorrection and with \placeongrid), the footnotetexts don't get typeset at all. They seem to get lost within the linecorrection environment.

catcode problems (mkiv)
by Peter Rolf 17 Jan '11

17 Jan '11

Hi, I have some problems with catcode handling in lua and tex. Source of the problem is (aside from my limited knowledge) a XML based line of text that can contain any printable character. From this source line I create one modified text line for the tex side (named 'textext') and one unmodified text line for the lua side (named 'luatext'). The tex side actually prints the text and the lua side is used to create some bitmap based background graphics. The XSLT output is something like this (saved in a *.tex file) ... \ctxlua{myluacode.foo{ luatext = [[Test |%_^~$#{}±©®¶°<>& 123]], textext = [[Test \textbar \%\_\textcircumflex \texttilde \$\#\textbraceleft \textbraceright \textpm \copyright \registered ¶\textdegree <>\& 123]], ... }} Two problems still occur. The "%"-sign in (ctx)lua (text is ignored afterwords) and the significant spaces in the tex part (which are eaten up when printed). I tried it with a modified catcodetable, but no success (ugly sideeffects). So my question is: What is the best way to 1. deal with the "%" character in ctxlua? 2. print significant spaces? My current 'solution' for 2. is writing to a tex buffer instead and then using \bgroup\obeyspaces\getbuffer[textext]\egroup If I try to use \obeyspaces in combination with the lua variable 'textext' I can no longer access the variable, as the variable is indexed by a tex macro (lets call it \FOO), which then is interpreted as whatever.["\FOO "].textext ). No solution for 1. yet. As always... any help welcome :-) Peter

Imposition with signatures (pdfpages/psbook emulation -- kind of announce)
by Marco Pessotto 16 Jan '11

16 Jan '11

Hello there. I deal very often with imposition, useful for zinesters and to create home-made booklets. ConTeXt by itself seems not to manage signatures, i.e., given a text long 200 pages, it should be imposed in smaller booklets of 50 pages each. (Or at least I didn't find anything about it) At the beginning I was using psbook. But this requires a slow processing (pdf -> ps; psbook ; ps -> pdf). Then I found out that pdfpages does the same thing (and better), and started using that. Now that I switched to ConTeXt, I found that I cannot use pdfpages without a latex installation. So I wrote a script and a module to do the same thing without having to install texlive. It uses MkIV and lua. The code is stored at http://gitorious.org/the-anarchist-library-tools/the-anarchist-library-tool… A minimal example and (minimal) documentation is provided. The code does basically 2 things: 1) the module, using the \alibraryflushpages commands, fills the output pdf (not imposed) with white pages, until it reach a “good” number, multiple of 4. The signature is calculated at runtime, so you can specify a minimum or a maximum (depends on your staple, if you can trim the paper, and so on). E.g., if the original pages are 128, no problem, the signature is 64 (16 sheets) and you can impose it without problems. But, if the original pages are 129, the optimal signature is 44, so the module will add 3 pages during the PDF compiling. 2) the perl script (which uses only standard perl libraries) creates a temporary context file, gets the number of signatures provided by the module (or passed as option if only the imposition is required against a pdf without tex sources), and does the actual imposing (the algorithm is taken from the psbook sources (the same used by pdfpages), including the pages in the right order. I'm not a real programmer, so it's a piece of spaghetti code. But seems to work. I'm posting this here because it's aimed to people that use the Minimals only, as TeXLive already ships pdfpages, psbook and pdfpages to do the same thing. (Well, the signature is not calculated on the fly by these tools). *If* there are people interested, I'd like to clean it up, improve it, document it a bit better and so on. If not, well, sorry for the noise. Bests -- Marco

\setupinterlinespace questions
by Florian Wobbe 16 Jan '11

16 Jan '11

Hi, a) this minimal example does not work as expected. The first column is not justified correctly on top. This does not change, even when swapping small, big, medium (e.g. make 1st col medium and 2nd small). The offset stays the same regardless of the linespacing. \starttext \startcolumns[n=3] \setupinterlinespace[small] \input knuth \column \setupinterlinespace[medium] \input knuth \column \setupinterlinespace[big] \input knuth \stopcolumns \stoptext b) Is there a possibility to use relative sizes like \setupinterlinespace[2*big] (which does not work)?

Bad interaction between new interpretation of underscore and modules
by Mathieu Boespflug 14 Jan '11

14 Jan '11

Hi all, today's beta introduced a really strange problem. Consider two source files: definitions.tex: \startmodule[definitions] \def\lambdax{\lambda_x} \stopmodule[definitions] main.tex: \usemodule[definitions] \starttext blah $\lambdax$ blah. \stoptext This results in the following compile error: ! Undefined control sequence. \lambdax ->\lambda_x l.5 blah $\lambdax $ blah. ? However, if you change "\usemodule[definitions]" into "\input definitions" instead, then there is no compile error! My understanding is that the underscore is a valid character for macro names now outside of math mode, which is what is causing the problem. But I really don't understand what magic is going on in the modules code to trigger this. I would be very interested in an explanation of what is going on. Many thanks, Mathieu
