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
by Oliver Heins 17 Jan '11

17 Jan '11

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. It should read: fi ff ffi ffl 1234567890 Using latex, one would use \input glyphtounicode.tex \pdfgentounicode=1, but this doesn't seem to work with context. Context used pdfr-def, but this seems to be mkii-only.

continious entries in table of contents?
by Oliver Heins 17 Jan '11

17 Jan '11

Is it possible to set up the table of contents in a way that entries of some level get typeset continiously? I want the entries of the subsubsection level (level 4) to appear in a single block, not as individual lines: [...] 3 Das Autobiografische in den Filmen der Nouvelle Vague 3.1 Film als Kunstwerk 61 3.1.1 Das Autorenkino 61 3.2 Autobiografie als Kunstwerk 68 3.2.1 Autobiografie-Theorie in Frankreich und Deutschland im historischen Vergleich 81 Frankreich 81 Exkurs: Existenziell reflektierende Autobiografie 83 Deutschland 94 3.2.2 Das Autor-Subjekt: Nouvelle Vague – Nouveau Roman 87 3.3 Film und Autobiografie werden Kunst 96 [...] This is my code so far, which works fine except the consecutive lines: \setupcombinedlist[content][level=4,alternative=a,distance=1em, pagecommand={\hskip1em }] \setuplist[chapter][width=0mm,style=\sc,pagestyle=normal] \setuplist[section][width=0mm,margin=1em] \setuplist[subsection][width=0mm,margin=2em] \setuplist[subsubsection][width=0mm,style=slanted, pagestyle=normal,margin=3em] TIA, olli -- Oliver Heins heins(a)sopos.org http://www.sopos.org/olli GPG: F27A BA8C 1CFB B905 65A8 2544 0F07 B675 9A00 D827 1024D/9A00D827 2004-09-24 -- gpg --recv-keys 0x9A00D827 Please avoid sending me Word or PowerPoint attachments: http://www.gnu.org/philosophy/no-word-attachments.html

Hi Aditya, Up to now I was using the context version shipped from ubuntu repo. Namely, it is the 2009.11.26-2 context version (maverick distribution). I upgraded, as you suggest, to latest version and everything is going right. Huge thanks.

This is definitely a bug and I will look into it. Which version of ConTeXt are you running? \div works correctly with 2011.01.06.

\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 16 Jan '11

16 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
