Changing font for math function

I don't get it, is there something that I missed with that \mathupright? (And I'm not managing to download the new beta of yesterday so I don't have access to the new code yet). Appart from that story of \text or not \text, what do you think about the suggestion that I gave in the conclusion of my previous post? Do you plan to still use version 1 or to implement version 2 after the freeze for TeXLive 2015? My conclusion was: CONCLUSION. — It all comes down to the choice of the best user interface for math functions and math texts (usually used as subscripts of variables). Their styles and colors is handled with \setupmathematics. There are two choices of user interface: 1. $\normalmathop{\mfunction{Arsinh}}\nolimits x\ \text{and}\ n_{\mtext{air}}$. 2. $\mfunction{Arsinh} x\ \text{and}\ n_{\mtext{air}}$. First, the default functionstyle and textstyle in \setupmathematics should be \rm\tf (the text mode equivalent of \mathupright, as we are always in text mode thanks to the \text hardcoded in \mfunction and \mtext). Then, in the 1st solution \normalmathop is used instead of \mathop because the latter is modified by ConTeXt to convert \rm to \mf, which makes \setupmathematics[functionstyle=\rm] without effect. The 2nd solution is obviously way cleaner, that is why I think it should be preferred. The implementation is given in my '2nd DEFINITION of \mfunction' for replacing the existing definition in math-ini.mkiv: ——————————————————————— \unexpanded\def\mfunction{\dosingleempty\domfunction} \def\domfunction[#1]#2% {\iffirstargument \doifelse{#1}{op}{\normalmathop{\text{\usemathematicsstyleandcolor\c!functionstyle\c!functioncolor#2}}}{\doifelse{#1}{limop}{\normalmathop{\text{\usemathematicsstyleandcolor\c!functionstyle\c!functioncolor#2}}}{\normalmathop{\text{\usemathematicsstyleandcolor\c!functionstyle\c!functioncolor#2}}\nolimits}} \else \normalmathop{\text{\usemathematicsstyleandcolor\c!functionstyle\c!functioncolor#2}}\nolimits \fi} ——————————————————————— We also saw that \mfunctionlabeltext is inconsistent with ConTeXt \labeltext because the former has a style attached to it, so \mfunctionlabeltext should be removed from math-ini.mkiv and \mfunction{\mathlabeltext } should be used instead when needed. To go even further in userfriendlyness, we the new macro \definemathcommand should be added in math-ini.mkiv: ——————————————————————— \unexpanded\def\definemathfunction{\dodoubleempty\dodefinemathfunction} \def\dodefinemathfunction[#1][#2]#3% {\ifsecondargument \definemathcommand[#1]{\mfunction[#2]{#3}} \else \definemathcommand[#1]{\mfunction{#3}} \fi} ——————————————————————— Finally, with this new \mfunction definition and the removal of the misleading \mfunctionlabeltext, the functions defined in math-def.mkiv should be rewrite as: ——————————————————————— \definemathcommand[cos]{\mfunction{\mathlabeltext{cos}}} % Or \definemathcommand[cos]{\mfunction[nolop]{\mathlabeltext{cos}}}, it is the same. \definemathcommand[det]{\mfunction[limop]{\mathlabeltext{det}}} \definemathcommand[diff]{\normalmathop{\text{\mathfunctionstyle d}}\mathopen{}} %etc. ——————————————————————— or ——————————————————————— \definemathfunction[cos]{\mathlabeltext{cos}} % Or \definemathfunction[cos][nolop]{\mathlabeltext{cos}}, it is the same. \definemathfunction[det][limop]{\mathlabeltext{det}} \definemathcommand[diff]{\normalmathop{\text{\mathfunctionstyle d}}\mathopen{}} % It is a special function so it should still be treated with the more general \definemathcommand. %etc. ——————————————————————— ConTeXt users are now provided, if Hans agrees to implement the code given in this conclusion, with three extremely useful macros: — \mtext (that should be used for all math texts such as subscripts of variables): $n_{\mtext{air}}$; — \mfunction (the equivalent of LaTeX \operatorname macro of the amsopn package): $\mfunction{Arsinh} x$ $\mfunction[op]{Arsinh} x$ or equivalently $\mfunction[limop]{Arsinh} x$; — \definemathfunction (the equivalent of LaTeX \DeclareMathOperator macro of the amsopn package): \definemathfunction[arsinh]{Arsinh} $\arsinh x$ \definemathfunction[arsinh][op]{Arsinh} $\arsinh x$ or equivalently \definemathfunction[arsinh][limop]{Arsinh} $\arsinh x$.

before= and after= for \setuphighlight
by Kate F 15 May '15

15 May '15

Hi, I'm looking for something like \definehighlight which I can use to markup various things in inline body text. I want different environments to be able to have their own setups to configure how these appear, just as \setuphighlight would provide. However there's one situation which I can't think how to handle; I'd like to have a setup append and prepend some text, just like before= and after= for various other setups. If \setuphighlight had before= and after=, this would suit me perfectly. But it doesn't. Is there something similar to \setuphighlight which has before= and after=? Or any other ideas? Thank you, -- Kate

vim module: modify line wrapping
by Andreas Schneider 15 May '15

15 May '15

Hi, vimtyping already offers line wrapping by specifying "lines=split". However, some /lines/with/very/long/sequences/of/somehow/breakable/chars do not break at all. In that given example, I would like to also allow vimtyping to break lines at "/". Is something like that possible? And if so: how? Best regards, Andreas

bug in latest beta?
by Pablo Rodriguez 15 May '15

15 May '15

Hans, after upgrading to beta from 2015.05.13 23:52, the compilation of most of my documents crashes. I get two different errors depending on the document: error: .../ctxbeta/tex/texmf-context/tex/context/base/typo-itc.lua:148: attempt to call global 'setfield' (a nil value) error: .../ctxbeta/tex/texmf-context/tex/context/base/typo-itc.lua:159: attempt to call global 'setfield' (a nil value) I cannot provide a minimal sample now. I wonder whether the error itself might be enough to fix the issue. Many thanks for your help, Pablo -- http://www.ousia.tk

Setup narrower body text for sections
by Kate F 14 May '15

14 May '15

Hi, I'm typesetting unix manpages, where I want each section heading to be outset slightly relative to the body text of that section. In other words, I want the body text to have a left margin which is narrower than the page width. I know I can do this with something like: \startsection[title=Synopsis] \startnarrower blah blah blah \stopnarrower \stopsection But I'd much rather set the left margin (or achieving the effect of \startnarrower by some other means) using the setups for \startsection instead. That way I won't need to have \startnarrower .. \stopnarrower all over my document. I tried \setuphead[section][margin=3cm] but the margin applies to the heading, not to the body text of the section. Of course I could set margin=-3cm and make the entire page narrower, but then I'd also need to adjust the headers and footers to match. I thought I could perhaps use before= and after=, but those are of course before and after the heading, not before and after the body text. Is there a setup to wrap some commands around the body text? Or must I define my own \startxyz .. \stopxyz thingy, or is there a better way? Thanks, -- Kate

\placeongrid command
by Csikos Bela 14 May '15

14 May '15

Hello list members: Based on co-pagedesign.pdf document I'm experimenting with grids. I followed the examples mentioned on page 9-10 (Section 1.5) and used the code below: %begin code \setuplayout[grid=yes] \showgrid \starttext This is a line. This is another line in another paragraph. Third line, new paragraph again. \placeongrid{\framed{This is a framed line placed on grid, default setup.}} Some text. \placeongrid[bottom]{\framed{This is a framed line placed on grid bottom.}} Some text. \placeongrid[top]{\framed{This is a framed line placed on grid top.}} Some text. \placeongrid[both]{\framed{This is a framed line placed on grid both.}} Some text. \stoptext %end code All \placeongrid commands with different options give the same output. See the attached pdf file. What do I do wrong? I have context ConTeXt ver: 2014.01.03 00:40 MKIV current fmt: 2015.4.1 int: english/english I have another question related to grids. When grids are shown in the pdf file (as a result of \showgrid), Adobe Reader 9.5 (linux version) always gives the following error message when opening the file: "An error exists on this page. Acrobat may not display the page correctly. Please contact the person who created the PDF document to correct the problem." Despite of the message the file is shown correctly. Why is this message shown? Thanks, bcsikos

ConTeXt-defined colours broken in TikZ in MkIV with latest betas
by Mojca Miklavec 14 May '15

14 May '15

Hi, The following example works in MkII and it works in TeX Live 2014, but it fails with the latest beta (it draws a black rectangle instead of using the defined colour): \usemodule[tikz] \starttext \definecolor[mycol][r=0.9,g=0.8,b=0.8] \starttikzpicture \fill[mycol] (0, 0) rectangle (2,4); \stoptikzpicture \stoptext It would be really nice to fix this in time for TeX Live 2015. Thank you, Mojca

Prefix for figure number lost in unnumbered subsection
by Mojca Miklavec 13 May '15

13 May '15

Hi, Consider the following example where I wanted to remove subsubsection numbers (as one ends with way too many numbers otherwise). The figure numbering is screwed up, I get: - Figure 1.1 - Figure 2 - Figure 1.3 \setuphead [subsubsection] [number=no] \starttext \chapter{Chapter A} \section{Section B} \subsection{Subsection C} \placefigure[force]{correct prefix}{test} \subsubsection{Subsubsection D} \placefigure[force]{no prefix number}{test} \subsection{Subsection E} \placefigure[force]{correct prefix}{test} \stoptext How to fix that? (I know that I can used something else than subsubsection, but it would be nice to get a proper fix.) Thank you, Mojca
