\placeinitial after a heading
by Alexey Kryukov 25 Jan '14

25 Jan '14

Hi, If I attempt to insert a drop cap after a heading while the paragraph indentation is enabled, I get the following effect: all lines the drop cap spans except the first one (e. g. second and third in case of n=3) get an additional indent, equal to the \parindent. For example: \setupinitial[font=Bold sa 4,n=3] \setupindenting[yes,1em] \starttext \section{Knuth} \placeinitial \input knuth \stoptext I suppose this is not the intended behavior :) The problem doesn't occur if I enable indenting also for the first paragraph after the heading, but in this case, of course, the drop cap itself is indented together with its adjacent lines. So the following workaround is possible: \setupinitial[font=Bold sa 4,n=3, hoffset=\parindent,distance=-\parindent] \setuphead[section][indentnext=yes] Nevertheless it would be nice if this issue could be fixed. Also, is it possible to explicitly apply case conversion commands to a drop cap? Setting the 'style' option to \WORD or \word currently seems to have no effect. -- Regards, Alexey Kryukov <anagnost at yandex dot ru> Moscow State University Faculty of History

\placeinital special case
by Alan Braslau 25 Jan '14

25 Jan '14

Hello, I came across a special case where \placeinital would need some tuning. (It was found in Eglinton, G. and Calvin, M. (1966) "Chemical Fossils", Scientific American 216, 32-43.) In the following minimal example, the period following the capital W should be dropped as well, being kept associated with the initial. \starttext \placeinitial W. H. Bradley of the U.S. Geological Survey has sought a contemporary counterpart of the richly organic ooze that presumably gave rise to the Green River shale. So far he has located only four lakes, two in the U.S. and two in Africa, that seem to be reasonable candidates. \stoptext This curiosity is by no means an important problem, and perhaps one can identify other such cases (but I have not thought much about it!). Fixing this is probably trivial or it might be a challenge depending on how \placeinitial is implemented (I have not looked into fixing it either). I only report this to help ConTeXt continue to evolve towards the highest quality computer typesetting available. Alan

Tabulator in database file not passed to Lua
by Joshua Krämer 25 Jan '14

25 Jan '14

Dear list, I use the database module to load the lines of a file with some data. The lines are then separated with a lua script. I use lua, because I need to do some other things with the data (rounding numbers, combining some fields etc.) Please consider the following minimal working example: \usemodule[database] \defineseparatedlist [Data] [ before=, after=, separator={}, commentchar=\letterpercent, command=\Tabrow, ] \startluacode function explode(sep,str) if (sep=="") then return false end local pos,arr = 0,{} -- for each separator found for st,sp in function() return string.find(str,sep,pos,true) end do -- Attach chars left of current separator table.insert(arr,string.sub(str,pos,st-1)) -- Jump past current separator pos = sp + 1 end -- Attach chars right of last separator table.insert(arr,string.sub(str,pos)) return arr end function tabrow(fileline) local tabarray = explode(";",fileline) local tabline = "" for index,value in ipairs(tabarray) do tabline = tabline .. " / " .. value end return tabline end \stopluacode \define[1]\Tabrow{\ctxlua{context(tabrow("#1"))}} \starttext \processseparatedfile[Data][Test.dat] \stoptext This is the content of the file Test.dat: Eins;zwei;drei;vier Of course the line separation could be done easier with the database module. However, I thought this way I could use the tabulator as the separator in my file. But when I change the separator from ";" to "\\t", it doesn't work. I suppose this is because the tabulators are passed to Lua as spaces. Or is "\\t" the wrong code? Would it be possible to use tabulators as separators, if I load the file with lua and not with the database module? Kind regards, Joshua Krämer

setupalign and flushbottom
by Alexey Kryukov 24 Jan '14

24 Jan '14

Dear list, according to the wiki and the ConTeXt manual, the ConTeXt equivalent for the LaTeX \flushbottom command is \setupalign[line]. However in my tests this setting doesn't have the desired effect. For example: \setuplayout[height=720pt] \setuphead[subject][before={\vskip4pt plus 1fil},after={\blank[small]}] \setupalign[line] \showgrid \starttext \dorecurse{3}{\input knuth} \subject{My Subject} \dorecurse{8}{\input knuth} \stoptext Here at the first page there is a small gap between the last line and the page border, although the glue above the heading can safely be expanded to make the page filled. However I do get the desired result if I replace \setupalign [line] with a low-level command (\alignbottom). So what is the correct way to get pages bottom-aligned in MKIV? -- Regards, Alexey Kryukov <anagnost at yandex dot ru> Moscow State University Faculty of History

Misplaced \widehat and \widetilde in mkiv?
by Otared Kavian 24 Jan '14

24 Jan '14

Hi Hans, It seems that with the latest beta mkiv, version ConTeXt ver: 2014.01.23 01:55 MKIV beta fmt: 2014.1.23 \widetilde and \widehat in mathmode are misplaced (and this is so in any of the fonts I tried). Please compare the result of the following in mkii (where everything is correct) and in mkiv: %%%% begin tilde-hat.tex \starttext We set ${\widetilde n}(t) := n(1 - t)$, and ${\widehat u}(\xi) := \int_{{\Bbb R}}\exp(-{\rm i}x\xi)f(x)dx$. \stoptext %%%% end tilde-hat.tex The attached PDF is obtained with mkiv. Best regards: OK

[OT] pdf2htmlEX

Hi, Just some information: if you want to pass from pdf to html5, there is an amazing project I discovered: https://github.com/coolwanglu/pdf2htmlEX The "bad" things is that it does not preserve structures: each line is a structure in html5 generated document. Cheers, Xan.

\startnarrower[left, right] \completecontent[pageboundaries={0.1.1.5}] \stopnarrower
by Rudolf Bahr 23 Jan '14

23 Jan '14

Hello listmembers, ConTeXt ver: 2013.05.28 00:36 MKIV current fmt: 2014.1.6 I'm typesetting a book in A4 landscape and would like to indent the TOC at both sides. I tried two solutions which both didn't work as expected. 1. attempt with "\startnarrower[left,right] \completecontent[pageboundaries={0.1.1.5}] \stopnarrower": The output of the following minimalistic example is partly attached as .pdf file. I shortened there the textheight to 80mm. a.) I would expect the TOC to be midaligned. But it isn't. It is leftaligned. b.) I would expect the TOC stopped after the 5th subsection row at page bottom and to be continued at the next page due to "[pageboundaries={0.1.1.5}]". But it isn't. 2. attempt with "\line{\hfill\vbox{\hsize=.75\hsize\completecontent[pageboundaries={0.1.1.5}]}\hfill}", outcommented in the following example. The TOC is really indented at both sides, but it doesn't stop at all at page bottom. Something must be wrong here. But what?

New header

Hello, Thank you for your reply. I do not understand all of the code, even if I use MetaPost but with Asymptote. I would also fit the dimensions of my papers as I used to do (\usepackage [ a4paper, hmargin = 1.5cm, vmargin =1.5cm] {geometry}) Thank you.
