Space between lines with mathematical writings
by Fabrice Couvreur 17 Mar '18

17 Mar '18

Hello, When I write text with mathematics, I find that the space between two lines is not enough because the formulas overflow one over the other. How to correct this ? Thank you Fabrice \switchtobodyfont[asana,12pt] \definemixedcolumns [Mycolumns] [ n=2, separator=rule, rulecolor=, balance=, grid=strut, ] \setupalign[verytolerant,stretch,hanging] \starttext \startMycolumns \startitemize[n] \item Le taux d'évolution du prix du menu entre l'été 2012 et l'été 2015 est égal à \math{t_g=\frac{13,80-9,80}{9,80}\approx 0,4082}. On a alors \math{(1+t_m)^3=(1+t_g)}, soit \math{(1+t_m)^3 \approx 1,4082}. On en déduit que \math{1+t_m \approx 1,4082^{\frac{1}{3}}}. Finalement, \math{t_m\approx 1,4082^{\frac{1}{3}}-1\approx 0,1209}. Le taux d'évolution annuel moyen, arrondi à 0,01\,\%, du prix du menu entre l'été 2012 et l'été 2015 est 12,09\,\%. \item \math{13,80 \times 1,1209^2\approx 17,34}. Le prix en 2017 sera approximativement de 17,34 euros. \stopitemize \column \input knuth \stopMycolumns \stoptext

Custom sorting of "pseudo-language" in a register
by John Grasty 16 Mar '18

16 Mar '18

Hello all, I’m just getting acquainted with ConTeXt, and I am finding it so much more suitable for my work and needs. Thanks for the great software. Here’s my situation. I write in Slovene and in English, and I need to make numerous references to biblical passages. I want to create an index of these citations, but I want them in the order they appear in the Bible rather than alphabetical order. Henri Menke provided a perfectly workable solution on TeX StackExchange[^1], but because this is a multi-year project, I wanted to find a bit more permanent solution. I discovered I can use Lua LPEG to parse and normalize my citations so they are referenced in a uniform style. My problem comes in the register sorting. Hans, I saw where in the paste you have recommended a “pseudo-language” to implement a custom sort in such a situation. I have almost figured out how to accomplish this. (See the MWE below.) I have no problem with single word sections (Genesis, Exodus, etc.). I can turn off indicators, do the custom sort (see below), and I get the intended result. If I have a multiple word title (Evangelij po Janezu), that technique doesn’t work. The replacement for more than one word (or if a number is involved, like 1John) doesn’t seem to work. I have no doubt there is a good reason; I’m just a newbie! It seems my options are to: 1. Figure out how to do a replacement for a phrase or a book with a number in its name. Then this technique seems to work ok. 2. Or to add an entries and figure out some way to not print the first level in the index. So the indicator will be the book name, and underneath the chapter and verses will be listed with out the book name being repeated. Are there any ideas to point me in the right direction? Thanks so much for your help, John Grasty [1]: https://tex.stackexchange.com/questions/418575/custom-ordering-for-a-index-… - - - - \startluacode local utfchar, utfbyte = utf.char, utf.byte local sorters = sorters local definitions = sorters.definitions local replacementoffset = sorters.constants.replacementoffset local variables = interfaces.variables local gen = utfchar(replacementoffset + 1), utfchar(replacementoffset + 11) local exo = utfchar(replacementoffset + 2), utfchar(replacementoffset + 220) local jn = utfchar(replacementoffset + 4), utfchar(replacementoffset + 27) sorters.definitions['bbt'] = { replacements = { { "Geneza", gen }, { "Eksodus", exo }, { "Janez", jn }, }, orders = { gen, exo, jn } } \stopluacode \mainlanguage[sl] \defineregister[booksort] \setupregister[booksort] [language=bbt, n=1, indicator=yes, ] \starttext \booksort{Janez+5.2}One \booksort{Eksodus+2}Two \booksort{Geneza+45}Three \page \placeregister[booksort][language=bbt] \stoptext

Kerning/italic correction problem with TeX Gyre Bonum font
by Mikael P. Sundqvist 15 Mar '18

15 Mar '18

Hi Hans and others! I don't know if this is a problem with the font itself or if it is ConTeXt. In any case, the test file below gives strange output (attached). In particular the space/kerning after $f$ seems to be off. Ulrike Fischer reminded me in the StackExchange chat that not so long time ago there was some similar issue with \mathcal P discussed on this list. Is it the same problem? (The input $f \tracinglostchars=0 \Uchar"EEEFF$) indeed makes it look better between the $f$ and the parenthesis.) /Mikael %%% \setupbodyfont[bonum] \starttext \startTEXpage[offset=3bp] (Look at this $f$) and this $f$? (see also $k$?, $x$? and $z$?) There might be more problems (like between $t$ and the parenthesis in $e^t$) is too small. The space between $dx$ and the bar is too small: \startformula \Bigl|\int_0^\pi\sin x\,dx\Bigr|, \stopformula Look at the $f$ and the bar: \startformula \Bigl|\int f\Bigr| \stopformula The $x$ seems to be outside the fraction: \startformula \frac{a^2}{1-x} \stopformula We add another one (in fact two) including $f$: \startformula f\Bigl(\frac{a+b}{2}\Bigr) \stopformula Also look at $\xi_0$ and $\xi_1$, the subscripts are too far away from $\xi$. Compare with $f_0$ and $f_1$, $g_0$ and $g_1$. With $\delta_f$ and $\delta_g$, I think it looks like the space is too big, in particular between $\delta$ and $f$, but maybe that is a matter of taste. \stopTEXpage \stoptext %%%

12th International ConTeXt Meeting: Announcement and Call for submissions
by Taco Hoekwater 07 Mar '18

07 Mar '18

== Announcement == The ConTeXt Group and Pragma ADE are looking forward to welcoming you at the 12th International ConTeXt Meeting that will take place on September 2-8, 2018 in Prague–Sibřina, Czech Republic. The meeting will host ConTeXt and LuaTeX developers and users and gives you the opportunity to present your results, experiences and ideas on future development. The presentations will be accompanied by tutorials on different ConTeXt and LuaTeX techniques. Registration will open on May 1. Future updates to this announcement will be made once we set the fees and finalise the registration form. == Call for submissions == We always set a theme for the meeting, and the theme for this meeting is: Unusual usage of ConTeXt While ConTeXt is mainly intended to be used for typesetting documents, these days with the addition of Lua as an embedded programming language, many other possibilities exist. We trust there are quite some ConTeXt users that treat ConTeXt like the proverbial hammer on anything resembling a long (or short) digit. As usual, anything at all related to ConTeXt that you would like to share is an acceptable subject really. Bet it for a presentation, tutorial, discussion, Q&A session, demonstration, workshop, recital, sketch, or sermon. Please consider doing a short presentation at the meeting! The programme committee is Hans Hagen and Taco Hoekwater, feel free to email them with hints and ideas. == website == For the meeting: http://meeting.contextgarden.net For the Context Group: http://group.contextgarden.net Taco Hoekwater Elvenkind BV

Fourier and utopia
by Mikael P. Sundqvist 06 Mar '18

06 Mar '18

Dear Hans and dear list, I try to use the fourier/utopia combination in mkiv (I used that combination for my PhD thesis in mkii 10 years ago). First of all, I have downloaded the fourier fonts from ctan at https://ctan.org/tex-archive/fonts/fourier-GUT . The fonts are found by mtxrun. I have one folder containing type-fourier.mkiv, fourier-math.lfg and testfile.tex. Everything seems to be found by the system, so the problem is probably in my files somewhere. The resulting pdf after compiling testfile.text is attached. Any ideas of what I am missing? Additionally, the fourier fonts come with fourier-bb.tfm (probably with blackboard bold), fourier-mcl (probably so that one can use mathcal). Any ideas on how to use them in the fourier-math.lfg file? If more information is needed, then please tell me. /Mikael %%% type-fourier.mkiv: %%% \starttypescriptcollection[fourier] \starttypescript [serif] [fourier] \definefontsynonym [Utopia-Regular] [file:putr8a.afm] \definefontsynonym [Utopia-Italic] [file:putri8a.afm] \definefontsynonym [Utopia-Bold] [file:putb8a.afm] \definefontsynonym [Utopia-BoldItalic] [file:putbi8a.afm] \stoptypescript \starttypescript [serif] [fourier] [name] \setups[font:fallback:serif] \definefontsynonym [Serif] [Utopia-Regular] \definefontsynonym [SerifItalic] [Utopia-Italic] \definefontsynonym [SerifBold] [Utopia-Bold] \definefontsynonym [SerifBoldItalic] [Utopia-BoldItalic] \stoptypescript \starttypescript [math] [fourier] [all] \loadfontgoodies[fourier-math] \definefontsynonym [MathRoman] [fourierrm@fourier-rm] \stoptypescript \starttypescript [fourier] \definetypeface [\typescriptone] [rm] [serif] [fourier] [default] \definetypeface [\typescriptone] [ss] [sans] [modern] [default] \definetypeface [\typescriptone] [tt] [mono] [modern] [default] \definetypeface [\typescriptone] [mm] [math] [fourier] [default] \quittypescriptscanning \stoptypescript \stoptypescriptcollection %%% fourier-math.lfg: %%% return { name = "fourier-math", version = "1.00", comment = "Math font Fourier for Utopia.", mathematics = { mapfiles = { "fourier.map", "mkiv-base.map", }, virtuals = { ["fourier-rm"] = { { name = "putr8a", features = "virtualmath", main = true }, { name = "fourier-ml.tfm", vector = "tex-mr", skewchar=0x7F }, { name = "fourier-mlit.tfm", vector = "tex-mi", skewchar=0x7F }, { name = "fourier-mlit.tfm", vector = "tex-it", skewchar=0x7F }, { name = "fourier-mlb.tfm", vector = "tex-bf", skewchar=0x7F }, { name = "fourier-mlitb.tfm", vector = "tex-bi", skewchar=0x7F }, { name = "fourier-ms.tfm", vector = "tex-sy", skewchar=0x30, parameters = true }, { name = "fourier-mex.tfm", vector = "tex-ex", extension = true }, msam, msbm, }, } } } %%% testfile.tex: %%% \loadtypescriptfile[type-fourier] \setupbodyfont[fourier,12pt] \starttext \startTEXpage[offset=3bp] Some math: $y''=(y')'$.

option for printing range
by Pablo Rodriguez 06 Mar '18

06 Mar '18

Hans, would it be possible to add an key to \setupinteractionscreen that implements the /PrintPageRange key in the /ViewerPreferences dictionary (https://www.adobe.com/content/dam/acom/en/devnet/acrobat/pdfs/PDF32000_2008… For example, "\setupinteractionscreen[range={2, 4-7, 10}]" should add the "/PrintPageRange [1 1 3 6 9 9]" in /ViewerPreferences. (BTW, the key name is the first one that came to my mind.) This is extremely useful to help the user to print only the required pages and not the whole document (which may be required only for viewing purposes). Many thanks for your help, Pablo -- http://www.ousia.tk
