by Jaroslav Hajtmar 05 Dec '11

05 Dec '11

Hello ConTeXist. Sorry for the beginner question, more for Lua(TeX) experts. Can somehow be achieved that the parameter of TeX macro get to luafunction unchanged? In the debug.txt file is the result obtained. Thanx Jaroslav \startluacode debug=io.open("debug.txt","w+") function testfun(param) debug:write(param) -- tex.print(param) end \stopluacode \def\testmac#1{\directlua{testfun('#1')}} \starttext $\frac{x_\alpha+y_\beta}{z_\gamma}$ \testmac{\frac{x_\alpha+y_\beta}{z_\gamma}} \stoptext

Bad linebreak in ToC
by Markus Finke 05 Dec '11

05 Dec '11

Hello, I don’t understand the behaviour in the second line – this line is not really filled, but there is a linebreak (in case of some hyphenations quite ugly too) Any solution?

Re: [NTG-context] Interlinespace in layers
by Jan Heinen 05 Dec '11

05 Dec '11

I solved the problem myself: First I used \showstruts to se struts - and only before and after the first line there were struts. Then I added the following argument into the \setlayerframed: strut=no \setlayerframed [Kontaktdaten] [ width=80mm, height=180mm, hoffset=50mm, voffset=50mm, frame=on, align=right, strut=no] {\FontKlein\setupinterlinespace[8pt] Ich bin Blindtext ...} I don't understand this problem with the strut but I solved it :-) Regards Jannis

Interlinespace in layers
by Jan Heinen 04 Dec '11

04 Dec '11

Hello, I am struggling with interlinespace and layers. With the help of this mailinglist I managed to use layers and to format the text in the layers. There is only one error I can't get rid of: before and after the first line of my text in a layer there ist a bigger space. In all the other lines of the text the interlinespace is ok. You can see the result here: http://www.imagebanana.com/view/gvv2twwv/paragraphinlayersetupinterlinespac… And this is my soucecode: \usemodule[simplefonts] \setmainfont[latinmodernsans] \definefont[FontKlein][Serif at 8pt] \definelayer [Kontaktdaten] [ x=0mm, y=0mm, width=\paperwidth, height=\paperheight, state=start ]% size is ignored! \setupbackgrounds [paper] [ background=Kontaktdaten, state=start ]% \starttext \setlayerframed [Kontaktdaten] [ width=80mm, height=180mm, hoffset=50mm, voffset=50mm, frame=on, align=right] {\FontKlein\setupinterlinespace[8pt]Ich bin Blindtext.

Saving module data in tuc file
by Aditya Mahajan 04 Dec '11

04 Dec '11

Hi, How does one save and read third-party data in tuc file at the lua end? I am trying to write a module t-ifchanged that defines a \doiffilechanged macro that provides the functionality of mtxrun --ifchanged without calling an external program (This is meant to be a support module for t-vim, where the external calls to mtxrun are too time consuming). I can successfully write additional data to the tuc file, but cannot figure out how to initialize the data from tuc file. (See attached file). Any hints are welcome. Aditya

Fractions and binomial inlined in text ($n \choose \frac{n}2$): Parentheses not scaled
by Paul Menzel 04 Dec '11

04 Dec '11

Dear ConTeXt folks, using the following minimal example \starttext Using \type{\choose} in text $n \choose \frac{n}2$. \startformula n \choose \frac{n}2 \stopformula \CONTEXT\ \contextmark\ \contextversion\ with \texenginename\ \texengineversion \stoptext the parentheses of the binomial in the text or too short. I guess this is because the parentheses are not scaled when inlined and that this is also a TeX limitation and therefore expected? ConTEXt MKIV 2011.11.25 21:29 with LuaTeX 0.70.1 Thanks, Paul

issue with logo and aalt
by Pablo Rodríguez 04 Dec '11

04 Dec '11

Hi there, the following minimal sample shows one problem I have when using all small caps (all lowercase and small caps) in titles. \setuppapersize[A4,landscape] \setuppagenumbering[location=] \usemodule[simplefonts][size=200pt] \setmainfont[TeX Gyre Pagella] \definefontfeature[allcaps][default][aalt=yes] \starttext \TeX \addfs{allcaps} \TeX \stoptext The logo in small caps has the letter E than in the all caps. My question is how should I redefine the TeX logo so that the all small caps version, i.e. that both logos have the letter E at the same height? (Otherwise, the all small caps logo seems weird.) Thanks for your help, Pablo -- http://www.ousia.tk

Title page for diploma thesis
by Paul Menzel 04 Dec '11

04 Dec '11

Dear ConTeXt folks, I am trying to format the title page for a diploma thesis. Looking at the Wiki most of the title or cover pages just have the title centered and maybe a subtitle right below [1]. \starttext \definemakeup[titlepage][align=middle] \starttitlepagemakeup {\definedfont[Serif at 20pt]University} \blank[big] {\definedfont[Serif at 20pt]\sc Institute} \vfill {\definedfont[Serif at 20pt]Diploma thesis} \blank[big] {\definedfont[Serif at 30pt] \setstrut \strut Interesting topic} \vfill by John Doe \stoptitlepagemakeup \stoptext 1. Is using `\blank` the recommended way to format the page? Or is using boxes and placing them manually “better”? 2. Looking at the output it is not centered exactly and a little bit to the left. Why is this the default? Does anyone know? Looking at the manual [2] in chapter page design (p. 29, screen version) this seems to be the backspace value. Is there an easy way to center it according to the whole paper width? Additionally I would have guessed it to be more on the right when glueing or trussing up(?) (German binden) the pages. Thanks and I am sorry for the sleight off-topic second question, Paul [1] http://wiki.contextgarden.net/Simple_Cover_Page [2] http://www.pragma-ade.com/general/manuals/cont-eni.pdf
