tex.toks & cld -- something weird
by Philipp Gesang 31 Oct '10

31 Oct '10

Hi all, while playing with the new extended cld stuff I encountered this: ----8<----------------------------------------------------------- context.starttext() context("\\toks0 = {Something}") context("\\the\\toks0") -- works --context(tex.toks[0]) -- fails print("·································································") print(tex.toks[0]) -- ‘The key mentioned above can't be used in a’ print("·································································") context.stoptext() ----8<----------------------------------------------------------- After setting ‘\toks0’ it cannot be accessed through ‘tex.toks’. Now, what’s so peculiar about this is that ‘tex.toks[0]’ carries a string from -- ‘thrd-tab.tex’‽ Any explanation? Did I miss something important? Thanks for any help, Philipp -- () ascii ribbon campaign - against html e-mail /\ www.asciiribbon.org - against proprietary attachments

Hi, the "%" is a frequently used character in URL. But \hyphenatedurl{} can deal with it ... Does someone has a fix? \starttext text\footnote{test \hyphenatedurl{www.test%it.com} test.} text. \stoptext Thanks, Steffen

Stop with an error signal
by Aditya Mahajan 31 Oct '10

31 Oct '10

Hi, I want to write a macro that checks for some settings and if the settings are wrong stop the current compilation and terminate with an error message. Right now I have \def\ERROR {\writeline \showmessage\??externalfilter??{forbidden}\getexternalfilterdirectory \batchmode \normalend} This prints the error message on the terminal and exits. However the exit status (the value of $?) is 0, if the tui file has changed the document is compiled a second time anyways. How can I force context (the macro package) to exit with a status of 1 so that context (the program) does not attempt a second compilation? Thanks. Aditya

Grid typesetting
by Andrzej Orłowski-Skoczyk 30 Oct '10

30 Oct '10

Hello Contexters I've been typesetting (mainly books and reports) in LaTeX for ca 15 years now. Recently I got really fed up with various problems related to typesetting on grid in LaTeX, and this is how I learned about ConTeXt. You can't imagine how excited I was when I started reading about it, especially given my recent grid-related LaTeX frustrations. Now I'm past all the ConTeXt manuals available in English, but still with no practical experience. ConTeXt is still a wild animal to be tamed, for me, but with a lot of sex appeal. So - it's grid that attracted me. But I can't get it - the grid - in my test document. I find it hard to understand what the below commands (which are hardly documented) do: - placeongrid, - moveongrid, - start/stop|linecorrection and how is "framed" related to them. I experimented with various settings/combinations of the above, but none seem to actually FORCE my content on the grid. The explanation in the manual is not clear for me, there is no explanation in the Wikia. What I need is a way to FORCE a line of text onto nearest grid line available (so that baselines match), for example: - on page opening a chapter, so that all body text is forced on grid regardless of the amount of space taken by headers etc., - on any page, when the text is being interrupted by figures, tables, formulas or fancy breaks. Is there an easy way to accomplish that? By 'easy' I mean other than manual setting the height of headers/figures/tables/formulas/fancy breaks so that following text sits on the grid (which is more or less also doable in LaTeX). Thank you. -- Andrzej Orłowski-Skoczyk

Default length units - can I change them from pt to bp or dd?
by Andrzej Orłowski-Skoczyk 30 Oct '10

30 Oct '10

Can I [easily] change the output of commands like \showlayout to show dimensions in bp/dd rather than pt? As a traditionalist I try to stick to dd/cc standard. For compatibility with others I sometimes have to use bp standard. I find TeX native standard of pt useless and very confusing. I would be happy to never see those pts around any more. Is that possible with ConTeXt? -- Andrzej Orłowski-Skoczyk

tex @ stackexchange.com
by Taco Hoekwater 30 Oct '10

30 Oct '10

Hi all, If you are bored (it is the weekend, after all) please have a look at and consider joining this new Q&A site: http://tex.stackexchange.com/ A blurb to promote the site itself, not by me: <advert> StackExchange is specialized StackOverflow, which is a social website for programmers. StackExchange sites offer moderated (like digg), tagged (like delicious) questions and answers (like traditional mailing lists and forums). Plus avatars and badges for additional fun. For [him], StackExchange works really well for answering what I can and learning from the experts when I can't. Signing up is easy--you can link to your Facebook, Google, or OpenID account so no need to remember another username and password. The TeX SE site is in public beta now and could benefit from more users, more questions, and more answers. </advert> Why I ask: I think the site is a nice idea. For once, I have absolutely nothing to do with its existence, but I am a regular poster there, as are some other context users (Aditya, Patrick). I think this is a nice a idea for a number of reasons, but two reasons stand out. First, if someone asks a question on Google and finds a link to tex.se, they will see a nice website (as opposed to say a mailing list archive) and that will therefore promote TeX in general. Second, this gives us a nice opportunity to promote ConTeXt in a place that is mostly searched by (beginning) LaTeX users. At the moment, there is not that much content about ConTeXt on tex.se, which I think is a shame. I know people are used to this mailing list and the wiki, but please consider to now and then ask a question or write a context answer on tex.se. Best wishes, Taco

Dear TeXies! The autumn meeting of the NTG will take place on October 27, 2010, from 10:00 until 16:30. We will meet at one of the locations of the Netherlands Defence Academy: complex 'Kasteel van Breda', Kasteelplein 10, 4811 XC Breda. The meeting will take place in building "'t Uiltje". The program is as follows: * John Haltiwanger: typesetting poetry (ConTeXt) * Hans Hagen: Tagged PDF (requirement for archival pdf) * Hans Hagen: Context Lua Documents (cld) * Taco Hoekwater: texlive 2010 / tlcontrib * Taco Hoekwater: Luatex in TeXlive 2010 * Frans Goddijn (+ Willi Egger): Eurotexquotes booklet production * Discussion topic: The rise of e-readers: will this be the end of typesetting or will we manage to survive? There will also be an opportunity to show off your own work, with two hands at the keyboard ... We cordially invite you to join us at this meeting. Please email Willi Egger or me with your personal details (because of NDA rules, we will need to know your passport or ID card number). Regretfully, it is extremely short day now (we apologize that we did not send this message to ntg-context earlier). If you do want to join us, please let us know before Thursday (tomorrow) evening. Best wishes, Taco Hoekwater NTG President

Footnotes in MkIV and MkII
by Matija Šuklje 29 Oct '10

29 Oct '10

Hullo, from what I can understand I'm using \footnote correctly (i.e. as on wiki), but if I generate the document with 'context' every footnote instance is just a direct copy of the first footnote. If I generate it with 'texexec' though, the footnotes are generated as expected. Is that a MkIV bug, feature or just me being stupid?
