I've found it is a general problem with the centering the last line when hanging alignment is set. Here is the similar thread, but with no response: https://www.mail-archive.com/ntg-context@ntg.nl/msg32884.html This is quite old thread. Are there any new possibilities in the Context from that era? Thanks, Jan

It has given me exactly what I needed. In fact one "\startmakeup[standard] - \stopmakeup"-pair, with is dedication-text, was sufficient for my doublesided document. I did not know of this command and its workings. Best regards, Robert

Additional unnumbered pages behind a title page
by Robert Blackstone 07 Feb '14

07 Feb '14

Dear list, For a Thesis, doublesided, I need three unnumbered pages behind the Title-page, the second of which contains only a dedication "To the memory of A". For the Title-page I use standardmakeup but ConTeXt apparently does not like me to add a second .tex-file with standardmakeup. How can I manage to accomplish this in a way worthy of ConTeXt? Thanks in advance for any advice Best regards, Robert Blackstone (I did find a hack, consisting of introducing between the Title-page and the FrontMatter a .tex-file, beginning with \setuppagenumber[state=stop], of which the second page is filled with stack of empty framed textboxes with their frames off. It does work somehow but I cannot believe that it is the right method.)

another question on simplefonts
by Pablo Rodriguez 05 Feb '14

05 Feb '14

Hi Wolfgang, I have the following code: \definefontfeature[fakeslanted][slant=.25] \definefontfamily[mainface][serif][TeX Gyre Pagella][slantedfont={* Regular},sl=features:fakeslanted] \setupbodyfont[mainface] \starttext This is {\em slanted}. \stoptext But I don’t know how to define "slantedfont={* Regular}" with the new syntax. "sl=style:tf" or "sl=style:regular" don’t work (the italic font is the slanted one). Which is the right way to do it in the new version of simplefonts? BTW, I think I should update the simplefonts article in the wiki to add the new syntax. After reading the font-sel.mkvi file, I have two questions: Which are the option keys that come before a colon? I mean, taking tf=style:bf as a sample, they would be style, file, features? Which ones am I missing? How about a new range preset for Hebrew? Many thanks for your help, Pablo -- http://www.ousia.tk

Hat with \widehat is not satisfactory

Dear list, I think the symbol of the angles is too close to the letters. Is it possible to change this ? \enablemode[pxmath] \setupbodyfont[palatino,12pt] \starttext \startformula \sin\widehat{PAM} =\frac{AM}{PA}=\frac{\frac{\sqrt{2}}{4}}{\frac{\sqrt{6}}{2}}=\frac{\sqrt{2}}{4}\times\frac{2}{\sqrt{6}}=\frac{\sqrt{2}}{2}\times\frac{1}{\sqrt{6}}=\frac{\sqrt{3}}{2}. \stopformula \stoptext Thank you.

Problem with matematics (derivative and brackets combinations) + wrong pagenumbering
by Jaroslav Hajtmar 05 Feb '14

05 Feb '14

Hello ConTeXist. I type some math now. When I use the symbol derivative in combination with symbols brackets, so the result does not look too good. Compared to the result in LaTeX output is almost unusable. It is possible to achieve a better result? In addition, I noticed that the page numbering starts from number 2. Is it a bug or I wrong? Thanx Jaroslav Hajtmar Here is my example: % This is LuaTeX, Version beta-0.78.2 (TeX Live 2013/W32TeX) (rev 4771) % ConTeXt ver: 2014.01.30 22:19 MKIV beta fmt: 2014.1.30 int: english/english \starttext $\left(f\pm g\right)'= f'\pm g'$ \blank[big] $\left(f\cdot g\right)'= f'\cdot g + f\cdot g'$ \blank[big] \mathematics{\left(\frac{f}{g}\right)'=\frac{f'\cdot g - f\cdot g'}{g^2}}, $g\neq0$ \blank[big] \startformula \left(\frac{f}{g}\right)'=\frac{f'\cdot g - f\cdot g'}{g^2} \stopformula \blank[big] $\left(c\cdot f\right)'=c\cdot f'$ \blank[big] $\left[f\left(g\right)\right]'=f'(g)\cdot g'$ \blank[big] \stoptext

Bookmarks with the specified label on
by Lei WANG 05 Feb '14

05 Feb '14

I have specified the headnumber of chapter to be "the Number chpt". By using \setuplist and \placelist with the attributes "label=yes", I could get a content with the label as what I want. But the headnumber of chapter label on bookmarks is still using "Number" intead of "the Number chpt". What should I do to enable this feature? A minimal example: \setuplabeltext[en][chapter={the , chpt}] \setupinteraction[state=start] \placebookmarks[chapter,section] \setupinteractionscreen[option=bookmark] \setuplist[chapter,section,subsection][alternative=c] \setuplist[chapter][distance=3em] \setuplist[section][margin=2em] \setuplist[subsection][margin=4em] \starttext \placelist[chapter,section,subsection][label=yes] \chapter{first} \input knuth \chapter{second} \input knuth \section{second2} \input knuth \subsection{second3} \input knuth \stoptext

draw random branched hydrocarbons
by DesdeChaves 04 Feb '14

04 Feb '14

I wrote this code to randomly draw organic branched structures. Since the organic structures have different dimensions I'm using the scale function to normalize the width. The result is a rather ugly because the structures are displayed with fonts with different sizes. Is there a way to normalize the structures width only when it exceeds a certain size? Thanks a lot Jorge \usemodule[chemie] \usemodule[fullpage][style={margin,empty},margin=15mm] \starttext \startluacode context.bTABLE() beginchemical="{\\scale[width=.40\\textwidth]{\\startchemical[height=fit,width=fit,frame=off]" endchemical="\\stopchemical}}" firstC="\\chemical[ONE, Z0, SAVE][H_3C]" -- go and branch below skeletonforBELOW={"\\chemical[RESTORE,MOV1,Z0,SB153,SAVE][CH]", "\\chemical[RESTORE,MOV1,Z0,SB5][CH_2]\\chemical[MOV1,Z0,SB153,SAVE][CH]"} -- "\\chemical[RESTORE,MOV1,Z0][CH_2]\\chemical[MOV1,Z0,SB5][CH_2]\\chemical[MOV1,Z0,SB153,SAVE][CH]"} -- go and branch above skeletonforABOVE={"\\chemical[RESTORE,MOV1,Z0,SB517,SAVE][CH]", "\\chemical[RESTORE,MOV1,Z0,SB5][CH_2]\\chemical[MOV1,Z0,SB517,SAVE][CH]"} -- go and not branch skeletonnobranched={"\\chemical[RESTORE,MOV1,Z0,SB5,SAVE][CH_2]", "\\chemical[RESTORE, MOV1,Z0,SB5][CH_2]\\chemical[MOV1,Z0,SB5,SAVE][CH_2]"} -- last C: two ways lastC={"\\chemical[RESTORE,MOV1, Z0, SB5][CH_3]", "\\chemical[RESTORE,MOV1,Z0,SB5][CH_2]\\chemical[MOV1, Z0, SB5][CH_3]"} -- branch below branchedBELOW={"\\chemical[MOV3, Z0, SB7][CH_3]", "\\chemical[MOV3,Z0,SB7][CH_2]\\chemical[MOV3,Z0,SB7][CH_3]", "\\chemical[MOV3,Z0,SB7][CH_2]\\chemical[MOV3,Z0,SB7][CH_2]\\chemical[MOV3,Z0,SB7][CH_3]", "\\chemical[MOV3,Z0][Cl]", "\\chemical[MOV3,Z0][F]","\\chemical[MOV3,Z0][I]"} -- branch above branchedABOVE={"\\chemical[MOV7, Z0, SB3][CH_3]", "\\chemical[MOV7,Z0,SB3][CH_2]\\chemical[MOV7,Z0,SB3][CH_3]", "\\chemical[MOV7, Z0,SB3][CH_2]\\chemical[MOV7,Z0,SB3][CH_2]\\chemical[MOV7,Z0,SB3][CH_3]", "\\chemical[MOV7,Z0][Cl]", "\\chemical[MOV7,Z0][F]","\\chemical[MOV7,Z0][I]"} -- rows for j=1,5 do context.bTR() -- columns for i=1,2 do context.bTD() -- begin chemical context(beginchemical) -- draw the first CH3 context(firstC) -- define the maximum for branches for k=1,3 do -- linear or branched branched=math.random(1,100)>30 if branched then -- below or above branchedBA=math.random(1,100)>30 if branchedBA then branch=branchedBELOW[math.random(1,6)]; skeleton=skeletonforBELOW[math.random(1,2)] else branch=branchedABOVE[math.random(1,6)]; skeleton=skeletonforABOVE[math.random(1,2)] end context(skeleton) context(branch) else -- no branch context(skeletonnobranched[math.random(1,2)]) end end -- draw the last CH3 last=lastC[math.random(1,2)] context(last) -- end chemical context(endchemical) context.eTD() end context.eTR() end context.eTABLE() \stopluacode \stoptext

two question on ConTeXt terminology
by Pablo Rodriguez 04 Feb '14

04 Feb '14

Dear list, I’m writing a document on ConTeXt and I have two questions on terminology. As I have been using LaTeX over a decade, I don’t know whether my descriptions are accurate in ConTeXt. Don’t worry, My questions are extremely basic ;-). What is the name for the part of the document that comes before \starttext? The ConTeXt manual seems to use preamble, but I would like to confirm this use. The other question is more tricky. Or at least I don’t find an obvious answer. Which is the correct expression to name any \start...-\stop....structure? Environment would be the LaTeX term, but this is reserved in ConTeXt. Many thanks for your help, Pablo -- http://www.ousia.tk
