Suggestion for bibtex: command to switch between upper and lower case for title
by Xenia 25 Mar '13

25 Mar '13

Dear context folks, I would like to have the possibility to change between upper and lower case in titles for bibliography items, e.g. for English and German items. This is controlled by the bst-files as described in [1]. But changing these files after an update is rather annoying. Is there maybe even such a function that I do not know? Thanks, Xenia [1] http://www.ntg.nl/pipermail/ntg-context/2011/059359.html

setups in the latest Context release
by Devendra Ghate 25 Mar '13

25 Mar '13

Hello Everyone I have been using the following setup (provided by Wolfgang on this list) to format my chapter headings till now. However, it does not work since I upgraded by context installation today. If the entire *\startlinealignment .... \stoplinealignment* block is copied outside the setups then it works fine. So the change must have been in the interface for *setups*. Please let me know if there has been a change OR I have made some kind of mistake. Thank you, Devendra Ghate ----------------------------- \startsetups[head:margin] \startlinealignment[left] \startframed [width=1cm, height=3cm, frame=on, align={flushleft,nothyphenated,verytolerant,low}] \headtextcontent \stopframed % \inmargin[location=outer,align={right}]{% \framed[% width=3cm, height=3cm, align={bottom,middle}, frame=on]{\headnumbercontent} } \stoplinealignment \stopsetups \defineheadalternative[margin][renderingsetup=head:margin] \definehead[dchapter][chapter] \setuphead[dchapter][alternative=margin] \starttext \dchapter{Inexpensive Monte Carlo} \stoptext -------------------------------- -- Cheers, Devendra.

structure: project, product, structureresetset, ...
by Alan BRASLAU 25 Mar '13

25 Mar '13

Hello, I have a *project* that consists of a book in 3 volumes. Each volume is a *part*. Each volume or part has a (recto-verso) title page. Each volume or part also has front and back matter: table of contents, bibliography, index, ... Each volume or part also has *appendices* Thus, I have 3 *products* corresponding to the three volumes. Each product has *components*: chapters, appendices, ... Now, I would like the second volume to know that it is Part II and the third volume to know that it is Part III. I would also like to continue the chapter numbering in succession in each volume: i.e. 1, 2, 3 in Part I; 4, 5, 6 in Part II; 7, 8, 9 in Part III. Furthermore, I would like the appendices to do likewise: i.e. A, B in Part I; C, D, and E in Part II; F in Part III. Of course, I need to specify in my *environment* \definestructureresetset [default] [0,0] [1] \setuphead [part] [sectionresetset=default,conversion=Romannumerals] But... how do I propagate the numbering from product to product, that is part to part? Everything was just fine when all of the parts were collected into a single product having a unique front and back matter and all of the appendices at the end... It should be simple, but sometimes I fail to see the obvious! :) Alan

upto current
by Hans Hagen 25 Mar '13

25 Mar '13

Hi, One these days there will be a first iteration of this years 'current' release. This has to do with the texlive code freeze. As usual the current is paired with a version of luatex and mplib, of which there also will be a frozen version soon. This year we also have luajittex. Among the biggest differences between this and the previous current are: - More low level tex code has been made mkiv compliant. This had a side effect of introducing bugs. As expected more flexibility an potential for extensions has not resulted in slower runs. - Some mechanisms have been rewritten, some even from scratch (a new table mechanism, multi columns). We tried to remain compatible but where possible inconsistencies have been removed. - Of course bugs have been removed also thanks to Wolfgang and others. Like before users have been very patient and willing to test. The updated wiki and good examples that show up on sites are an indication that mkiv has mostly replaced mkii. - There is some new math magic under the hood. We switched to tex gyre and latin modern open math as defaults. - Lua code has been optimized: leaner, meaner, less dependent, version 5.2 etc. There is more helper code available pending future extensions to mkiv. Basic code can be used in stock Lua. - The 2013 current performs significantly faster than previous versions and (certainly) on complex jobs mkiv outperforms mkii. Lots of time went into identifying and removing bottlenecks. - When luajittex is used, thanks to the faster virtual machine, mkiv benefits a lot: 20-490% faster runs are possible. I usually test with manuals I'm working on, but a nice base test is \dorecurse {1000} {test\page} which now runs 20% faster with stock luatex and 50% faster with luajittex. - The font database generator is made more efficient and unless you do a full reload take hardly any time to regenerate after an update. This means that updating betas is more convenient. In general all logging to the terminal and log file is faster due to several optimizations. - Some mtx scripts have been extended, some more will show up. - We ship a set of advanced scite lexers (tex, lua, cld, mp, w, xml, etc. plus a context setup) that can serve as benchmark for syntax highlighting context code. To some extent this also determines the way mkiv is coded. I probably forgot a lot. After the current is done, we can start thinking of what to do next. Here are some thoughts: - Improving the output routines. This is non-trivial. Maybe I'll rewrite the columnsets code. The mixed column figure placement can be improved too. - Some mechanism will get support for setups alongside commands, like sections and list related mechanisms already has. - Parts of the xml handling can be cleaned up, although the current code performs rather well already. - Support for sql might get more integrated into the core (a side effect of projects I'm working on). - I might pickup the metatex thread: a generic base with special purpose subsets of code. It might not be worth the trouble, but it's good to have a proper dependency tree. - I will continue making some of the Lua code more generic (maybe by introducing some additional namespaces). - I need to cleanup all the s-* files: namespaces, mkii->mkiv, etc. A tedious job. Clean up all mkiv presentation styles. (Something for rainy days or cold winter nights with stacks of new cd's to make that effort bearable.) - Play with a partial css simulator (relates to export), but only when I'm really bored or need it (getting css itself right is already enough of a challenge). - Pick up on ideas with respect to math dictionaries. Add some support for breaking large math formulas. Kick out more old code. - Play with alternative par builders, i.e. finally add the mkiv Lua parbuilder that I have around for years into the distribution. This relates to a drastic cleanup of expansion code in the luatex front- and backend. - Include some third party modules into the core distribution. - Remove bottlenecks in mkiv where possible (user input is needed for this). Then there are the documents: - Update the xml descriptions (Wolfgang has been working on this, and there is the wiki). - Finish the 'cld' manual (mostly done). - Update the 'xml' mkiv manual (doable, maybe users have examples too). - Finish the updated 'mathml' manual (done but needs checking but then I might overhaul the whole lot again). - Finish the more technical 'mkiv font' manual (tedious job but okay). - Pickup the 'stylistics' manual (also nice to do but a bit tedious). - Turn 'hybrid' into a more finished document (the second part of the history of mkiv/luatex). - Add more to the 'about' series (the third part). Of course this is too ambitious but it's good to remind myself that some work needs to be done. And ... users might have ideas of what needs to be done as well.

Nabla operator appears italic in formula
by Xenia 24 Mar '13

Dear context list, using the nabla symbol ∇ in formulas, I wondered why it looks italic and not upright as for example in [1]. I attach an example. Thanks, Xenia [1] https://en.wikipedia.org/wiki/Nabla_symbol

setupinterlinespace in \startquotation\stopquotation
by Alan BRASLAU 24 Mar '13

24 Mar '13

Hello, It can be quite common to typeset long quotations in a smaller typeface. The following minimal example is somewhat problematic: ------------------------------------------------------ \setupquotation [style=\tfx\setupinterlinespace] \starttext \startquotation \input tufte \input tufte \input tufte \stopquotation \stoptext ------------------------------------------------------ The interline spacing is wrong for the last paragraph. Adding a \par in the input before \stopquotation puts the right quotation closing mark on a newline. I suppose that the common practice is *not* to use explicit quotation marks when typesetting such long quotations in smaller typeface. In this case, setting left=,right= and explicitly putting a \par would work. However, if one wants to have quotation marks, this is no good. And placing an explicit \par is not very elegant, either. Nor does it seem that \switchtobodyfont[] does any better. Maybe the solution is simple but I have not found it... Alan

setupquotation and setupquote
by Alan BRASLAU 24 Mar '13

24 Mar '13

Hello, quotation is linked to quote. Indeed, we have in typo-del.mkiv \definedelimitedtext [\v!quote][\v!quotation] However, when the user then changes options using \setupquotation, \startquote\stopquote also gets modified. In the minimal example below, it is necessary to uncomment \setupquote in order to restore normal quote text. I believe that this to be a bug (and not a feature). \setupquotation [style=slanted] %\setupquote [style=normal] \starttext Tufte: \startquotation \input tufte \stopquotation Ward: \startquote \input ward \stopquote \stoptext

different page background for chapter title page
by Thomas A. Schmitz 23 Mar '13

23 Mar '13

Hi all, I'm sure there must be a solution for this, but I haven't been able to find it yet: I want my chapter titles typeset in a sort of frame which will span the entire page, not only the text area, so I guess the easiest way to do that would be a page background. How can I set up a background that will appear only on the title page, in addition to the regular background? Bonus question: I also want the color schemes of both backgrounds to be different in every chapter, so the solution should make this possible. The example is a bit silly, but it shows what I'm looking for, I hope. Thanks, and all best Thomas \setuplayout [header=0cm, topspace=1.625cm, footer=0cm, width=fit, height=fit] \definecolor [color:background] [r=0.86,g=0.61,b=0.54] \definecolor [color:title] [r=0.91,g=0.75,b=0.7] \startuseMPgraphic{background:normal} StartPage ; numeric h ; h = 10mm ; z[1] = ulcorner Page ; z[2] = urcorner Page ; z[3] = z[2] shifted (0, -h) ; z[4] = z[1] shifted (0, -h) ; path p ; p = z[1] -- z[2] -- z[3] -- z[4] -- cycle ; fill p withcolor \MPcolor{color:background} ; StopPage ; \stopuseMPgraphic \defineoverlay [background:normal] [\useMPgraphic{background:normal}] \startuseMPgraphic{background:title} StartPage ; numeric h ; h = 10mm ; z[1] = ulcorner Page shifted (0, -1.5*h) ; z[2] = urcorner Page shifted (0, -1.5*h); z[3] = z[2] shifted (0, -h) ; z[4] = z[1] shifted (0, -h) ; path p ; p = z[1] -- z[2] -- z[3] -- z[4] -- cycle ; fill p withcolor \MPcolor{color:title}; StopPage ; \stopuseMPgraphic \defineoverlay [background:title] [\useMPgraphic{background:title}] \setupbackgrounds[page][background={background:normal,background:title}] \starttext \startchapter[title=One] \input tufte \page \input knuth \stopchapter \startchapter[title=Two] \definecolor [color:background] [r=0.82,g=0.85,b=0.68] \definecolor [color:title] [r=0.86,g=0.88,b=0.76] \input tufte \page \input knuth \stopchapter \stoptext
