\definemathfence commands
by Otared Kavian 10 Sep '17

10 Sep '17

Hi everyone, With the command \definemathfence it is possible to define for instance the following command \definemathfence[duality][angle][command=yes,factor=auto] so that $\duality{T,\phi}$ results in $\langle T,\phi \rangle$ and the \langle and \rangle are appropriately scaled when necessary. How can one create a command called \bracparenth in order to get a left bracket on the left and a right parenthesis on the right, that is $\bracparenth{a,b} = [a,b)$ and so that when necessary it scales automatically. Below is the example for \duality. Thanks in advance: OK %%% begin mathfence-example.tex \definemathfence[duality][angle][command=yes,factor=auto] \definemathfence[parenth][parenthesis][command=yes,factor=auto] \starttext The action of $T$ on a smooth function $\phi$ is denoted by \startformula \duality{T,\phi} \stopformula while the scalar product of two functions $f$ and $g$ is denoted $\parenth{f|g}$. \stoptext %%% end mathfence-example.tex

But it is resolved now by doing the following according to the suggestions: run mtxrun —generate and luatools —generate May be, “ luatools —generate" is OK. I am using TeXshop in OS X. So I am not sure this works in Linux system. I hope that it may help. Good luck! Best regards, Dalyoung

mathalignment vs mathmatrix
by Henri 08 Sep '17

08 Sep '17

Dear devs, In the latest beta the interaction between mathalignment and mathmatrix is broken. The biggest problem is that documents containing this pattern do not typeset anymore at all! (That makes 100 errors; please try again.) Please fix. Cheers, Henri --- \define\Up{\mathord\Uparrow} \define\Dn{\mathord\Downarrow} \starttext \placeformula \startformula \startmathalignment \NC \psi_{+,\Up} ... \startmathmatrix \stopmathmatrix \NR \NC \psi_{+,\Dn} ... \NR \stopmathalignment \stopformula \stoptext

Expandable \doifelse tests
by Henri Menke 08 Sep '17

08 Sep '17

Dear list, Motivated by this question on TeX.SX https://tex.stackexchange.com/questions/370868 I was fiddling around with the \doifelse conditionals. I noticed that most of them are not expandable, which makes it very difficult to concatenate them. Here a simple example \starttext \doifelse{a}{% \doifelse{x}{x}{a}{b}% <- evaluates to "a" but not expandable }{yes}{no} \stoptext This outputs "no" even though "a" is equal to "a". Would it be possible to substitute these conditionals by expandable ones? I would volunteer to help make them expandable. Cheers, Henri

Thank you! I recommend to include this as a patch in ConTeXt. However: Testing never stops ;-) I have the following MWE: \definemathmatrix[pmatrix][left={\left(},right={\right)}] \math{ \startpmatrix \NC A \NC B \NR \NC C \NC D \NR \stoppmatrix} This (including your suggested fix) results in the following structure tree: <document> |-<math> | '-<mrow> | '-<mrow> | '-<mfenced> | '-<mrow> '-<math> '-<mtable> |-<mtr> | |-<mtd> | | '-<math> | | '-<mrow> | | '-<mi> | | '-"A" | '-<mtd> | '-<math> | '-<mrow> | '-<mi> | '-"B" '-<mtr> |-<mtd> | '-<math> | '-<mrow> | '-<mi> | '-"C" '-<mtd> '-<math> '-<mrow> '-<mi> '-"D" I think that the <mtable> should be located within the <mfenced>, shouldn't it? Cheers, Christoph

Substituting Greek characters in math mode
by Alan Bowen 07 Sep '17

07 Sep '17

I should like to have the Brill font substitute for the Greek alphabet (upper and lower cases) as well for the numerals in Tex Gyre Termes Math. So far, I have been able to get the Brill numerals (oldstyle) but nothing more: the Greek letters in math mode are from Termes Math. Here is what I have: \definefontfamily[mainface][serif][Brill] [protrusion=quality, expansion=quality, mode=node, force=yes, ] \definefallbackfamily[mainface][mm][Brill][range={0030-0039, 0391-03A9, 03B1-03C9}, scale=1] \definefallbackfamily [mainface] [mm] [Brill] [preset=math:lowercasegreeknormal] \definefallbackfamily [mainface] [mm] [BrillItalic] [preset=math:lowercasegreekitalic] \definefallbackfamily [mainface] [mm] [Brill] [preset=math:uppercasegreeknormal] \definefallbackfamily [mainface] [mm] [BrillItalic] [preset=math:uppercasegreekitalic] \definefontfamily[mainface][mm][TeX Gyre Termes Math][scale=0.94] \setupmathematics[autopunctuation={all}, ucgreek=normal, lcgreek=italic] \setupbodyfont[mainface,10pt] \starttext A~B~C~a~b~c \emph{A~B~C~a~b~c}\quad math: \m{A~B~C~a~b~c} 0123456789\quad math: \m{0123456789} δ \emph{δ}\quad math: \m{δ} π \emph{π}\quad math: \m{π} Π \emph{ Π}\quad math: \m{Π} \stoptext Any suggestions or pointers will be most welcome.

issues with \scitebuffer and \sciteinlinebuffer
by Pablo Rodriguez 06 Sep '17

06 Sep '17

Hans, after updating to latest beta (from 2017.09.05 15:10) to enjoy the new none method in the scite buffers, I have the following sample: \setupindenting[yes, always, big] \usemodule[scite] \setuptyping[margin=2cm] \startbuffer[typebuffer] | \ConTeXt\ \ConteXt \par \stopbuffer \starttext \scitebuffer[typebuffer] \scitebuffer[none][typebuffer] \letterbar a \sciteinlinebuffer[typebuffer]. b \stoptext And I’m experiencing the following issues: 1. "|" breaks compilation when method is set to "none". 2. "\sciteinlinebuffer" adds always an extra blank space after it. 3. Method "none" treats spaces as linebreaks and removes "\". 4. \setuptyping and \setuptype don’t work with the scite buffers. What am I doing wrong? Many thanks for your help, Pablo -- http://www.ousia.tk
