The context version of \medskip is \blank[medium]. Thanks Wolfgang. “\thinspace” works perfectly for my purpose. Oddly enough, \, gives no comma and a normal space, \. gives no period and no space with mkiv, and a superscript period with mkii. Could these forms for \thinspace perhaps be obsolete?

Update text variables inside metapost

Why the metapost not updated the value of text variables that are generated inside luacode environment? In the code below, If I have \startitemize[columns,two] then metapost draw: 1. \Bolha[size=6cm]{text1}{text2}{text3}, 2. and four \Bolha[size=4cm]{text1}{text2}{text3}, but text1, text2 and text3 is not updated in every call; If I omit the itemize environment or with \startitemize metapost only draw: 1. the first call of Bolha that is: \Bolha[size=6cm]{text1}{text2}{text3} 2. and four call of \Bolha[size=6cm]{text1}{text2}{text3} %% all new information is omited Jorge %%%%% code \def\Bolha[#1]#2#3#4% {\setupMPvariables[bolha][#1]% \setMPtext{labelcima}{#3}% \setMPtext{labelesquerda}{#2}% \setMPtext{labeldireita}{#4}% \useMPgraphic{bolha}} \startuniqueMPgraphic{bolha} path p, q, cima, esquerda, direita, vertical; pair A, B, C; p:=fullcircle scaled \MPvar{size}; A:= (point 4 of p); B:= (point 8 of p); C:= (point 6 of p); q:=A--B; vertical := .5[A,B]--C; cima := buildcycle(q, subpath(4,8) of reverse p); esquerda := buildcycle(subpath(4,6) of p, vertical, subpath(0,.5) of q); direita := buildcycle(subpath(6,8) of p, subpath(0,.5) of reverse q, vertical); draw p; draw q; draw vertical; label(textext( \MPstring{labelcima} ), center cima); label(textext( \MPstring{labelesquerda} ), center esquerda); label(textext( \MPstring{labeldireita} ), center direita); \stopuniqueMPgraphic \starttext \placefigure[center, nonumber]{}{ \Bolha[size=6cm]{$C_m$ (g/dm\high{3})}{mass (g)}{V\low{s} (dm\high{3})} } \startitemize[columns,two] %% try only \startitemize \startluacode flasks={20,25,50,100,200,250,500,1000} k=1 repeat Cm=math.random(1,10)/10 Vs=flasks[math.random(1,8)]/1000 mass=Cm*Vs --incognita=math.random(1,3) incognita=1 context.item() if incognita==1 then context("\\Bolha[size=4cm]{$C_m$}{%.2f g}{%.1f dm\\high{3}} mass=%.2f g", mass, Vs, mass) elseif incognita==2 then context("\\Bolha[size=5cm]{%.1f g/dm\\high{3}}{m}{%.1f dm\\high{3}} mass= hidde", Cm, Vs, mass) elseif incognita==3 then context("\\Bolha[size=5cm]{%.1f g/dm\\high{3}}{%.2f g}{V\\low{s}} mass=%.2f g", Cm ,mass, mass) end k=k+1 until k==5 \stopluacode \stopitemize \stoptext %%% stop code

page breaks before titles
by mf 07 Mar '15

07 Mar '15

Hello, I'm trying to typeset a book made of letters with ConTeXt. Every letter has a title a subtitle and a date, before it starts with "Dear ..." Like this: --------------------------------- Title subtitle where, when Dear ..., the rest of the letter ... --------------------------------- The letters are very different in length -- some are long, some are made of a couple of lines --, so I'd like to typeset them continuously, without skipping to a new page every new letter (\setuphead[LetterTitle][page=no]). This way a letter could finish beyond the half of a page, and the next one could have no space left to get the part from Title to the first lines of the body on the same page. That's why I disabled page breaks from Title to the first paragraph after "Dear ...": it would be ugly having only the title in one page and the rest in the next ones. But there's a side effect: the title of the new letter "pulls" the last two lines (the penalties are set to avoid one-line widows) of the previous letter to the new page, even when there's room for them on the previous page. In this case I would like ConTeXt to break the page at the end of the previous letter, before the next letter title. That's why I've set before={\blank[2*line]\page[preference]} in LetterTitle. But it does not work. Example: --------------------- --------------------- text of the previous text of the previous letter with room to be letter with room to be all typeset here all typeset here page 11 last two lines of the [room for >2 lines] the previous letter page break------------------- ==> ------------------- last two lines of the Title the previous letter subtitle ... page 12 Title subtitle ... -------------------- -------------------- Is there a way to know the vertical location where the previous letter ends, to decide whether to skip to a new page? Thanks in advance, Massi

To add labels to a grid, Hans wrote a macro hlintext (Min, Max, Step, Lenght , Format). I do not know what to put in "Format".

Using the standalone ConTeXt, how do I add access to my texmf-local tree
by Gerben Wierda 06 Mar '15

06 Mar '15

I’m trying to migrate to mkiv and I’m running into a host of troubles. Here is one: publications > wrote a new auxiliary file 'prd_book.aux' This is BibTeX, Version 0.99d (TeX Live 2014) The top-level auxiliary file: prd_book.aux The style file: cont-no.bst I couldn't open database file gwierda.bib ---line 3 of file prd_book.aux : \bibdata{gwierda : } The reason is that by using this command (. /usr/local/src/ConTeXt/tex/setuptex && context test.tex) I may have the latest ConTeXt compiling test.tex (it just adds that to te front of PATH), but I’ve lost access to additions I keep in /usr/local/texlive/texmf-local and ~/Library/texmf) How do I make sure the standalone ConTeXt gets access to these?

Dear list, I have the following sample: \setuppapersize[A5] \definemakeup[colophon][page={yes, blank, right}] \starttext \dorecurse{6}{\input zapf} \startmakeup[colophon] This is the colophon \stopmakeup I need to have the colophon in an odd page. I thought that the option page would do the work, but it doesn’t seem to work. Which is the right way to get a makeup on an odd page? Many thanks for your help, Pablo -- http://www.ousia.tk

Get rid of caption on an intermezzo.
by John Culleton 04 Mar '15

04 Mar '15

I managed after many trips to the Wiki to get a text frame pretty much as I want it, with text wrapping around and so on. But the technique requires using an intermezzo as a wrapper. This feature always puts a title like "intermezzo 1" at the bottom. How do I get rid of this title? For the curious here is my code segment to date: \setupframed[framecorner=round, frameradius=1em, background=screen, backgroundscreen=0.70, backgroundcorner=round, backgroundradius=1em, corner=round, radius=1em] \definefloat[intermezzo]{ } \kern 5em\placeintermezzo[right]{} \startframedtext[width=3.2in] \centerline{\ss\tfb Life Before Specialty} \centerline{\ss\tfb Food Marketing} \tfx What food entrepeneurs did before starting a specialty food firm (in order of prevalence): \startitemize[1] \item Other business non-food-related (52\%) \item food-related business (14\%) \item Medical profession (11\%) \item Education (8\%) \item Nonprofit Charity (8\%) \item Entertainment (3.6\%) \stopitemize ---{\bf\it Food Entrepeneur Magazine 2014 pool responses} \stopframedtext -- John Culleton Wexford Press Free list of books for self-publishers: http://wexfordpress.net/shortlist.html Updated PDF e-book: "Create Book Covers with Scribus 1.4.5" coming soon at http://www.booklocker.com/!

BachoTeX 2015: Various faces of typography
by Mojca Miklavec 04 Mar '15

04 Mar '15

---------- Forwarded message ---------- From: Jerzy Ludwichowski BachoTeX 2015: Various faces of typography ========================================== Since several years we are trying not to forget what TeX/MetaFont and their variants and combinations are for. Remember why Prof. Knuth set out to create TeX? We will continue in this spirit also during the forthcoming BachoTeX conference. Here is Andrzej Tomaszewski's rationale: Texts formed into direct or abstract writings and pictures are inseparable elements of the visual presentation of thought. During the millennia of our civilization this method of peoples communication reached the ability to record precisely scientific, social and artistic statements. Typography is an art of organizing text and in a broader context - publications as a whole. Text structures receive different shapes: from a sequence of simple sentences through futuristic poetry, statisticians tables, mathematicians formulas linguists dictionaries and even programmers listings. Sequences of alphanumeric signs require proper treatment – for once as a material for data processing and second, as a communique created for human readers consumption. This is what we will be talking about during BachoTeX. Papers/presentations ==================== Of course we look forward to the normal mix of TeX, MetaPost, ConTeXt, LaTeX, and friends related presentations. Please not not forget fonts! Please note the “Call for TeX Pearls” further down. The normal channel of offering papers is emailing proposals to the Program Committee, but before rushing off to the mailer, please consult the info for authors (http://www.gust.org.pl/bachotex/2015-en/submissions) Workshops and tutorials ======================= Especially welcome are proposals for TeX-related tutorials or introductions. If you have suggestions for tutorials or workshops by others than yourself or about specific topics, please let us know. The following are in initial planning: * calligraphy * book binding Poster sessions =============== Participants will be given the opportunity to present their TeX and typographic results in the form of posters for which we provide exhibition space. TeX Pearls ========== We continue the tradition of the “Pearls of TeX Programming”. MetaFont/MetaPost do also fall into that category. Details and previously collected pearls can be found at http://www.gust.org.pl/projects/pearls/. Deadlines and addresses ======================= The deadline for “regular” abstracts and other proposals is March 28th 2015. The deadline for final papers to appear in the conference materials is April 11th. Contributions should be send by email to the Program Committee: prog-2015 at gust dot org dot pl. The PC is chaired by Bogusław Jackowski (b underscore jackowski at gust dot org dot pl). For the Organizing Committee --Jerzy Ludwichowski (http://www.gust.org.pl/bachotex/2015-en)

siunitx feature in unit module
by Andrea De Michele 03 Mar '15

03 Mar '15

Hi, with siunitx LaTeX package its possible to obtain physics units like m/s printed in different way changing one option: e.g. \si{\metre\per\second} produce ms^{-1} \si[per-mode=symbol]{\metre\per\second} produce m/s \si[per-mode=fraction]{\metre\per\second} produce \frac{m}{s} have the unit module the same feature? If yes how can obtain the effect (I didn't find nothing on the manual)? Thank you for help -- Andrea De Michele
