Windows console message from utf-8 source
by Pablo Rodriguez 28 Apr '15

28 Apr '15

Dear list, I have the following minimal example: \starttext \message{En español usamos acentuación} \stoptext Saved as utf-8, Linux displays the message fine. (I guess MacOS X would do the same.) The problem is the standard console in Windows. It requires IBM codepage 850 exclusively. (Or at least, I don’t know how to display utf-8 strings.) Is there any way to display the content of the \message above as cp850 from a utf-8 source? Many thanks for your help, Pablo -- http://www.ousia.tk

System fonts not loading
by Mica Semrick 28 Apr '15

28 Apr '15

Hello, I seem to be having some trouble getting the system fonts to load from my Debian Jessie system. I'm using: mica@box:~/Working$ context -version mtx-context | ConTeXt Process Management 0.61 mtx-context | mtx-context | main context file: /home/mica/.context/tex/texmf-context/tex/context/base/context.mkiv mtx-context | current version: 2015.04.18 14:41 and OSFONTDIR is set and all the fonts I want to use are in ~/.fonts: mica@box:~/Working$ echo $OSFONTDIR /home/mica/.fonts/ Usually when I run into font problems or add a new font, I run: fc-cache -fv mtxrun --generate context --make This has worked for some time, however now it will not. Consider the following: \definefontfamily [junction] [rm] [Junction Regular] \definefontfamily [junction] [mm] [Latin Modern Math] \setupbodyfont[junction] \starttext \input ward \bf \input ward \tf \input ward \bf \input ward \stoptext which results in a pdf with Latin Modern. mtxrun --script fonts --list --all doesn't seem to be seeing the OS fonts, but sees all of ConTeXt's fonts. However, fc-list : family (which will list all the system fonts known by fc-cache) shows all the fonts as available. Thank you for any help. Best, Mica

caption alignment with floats in the margin
by Brian R. Landy 28 Apr '15

28 Apr '15

Hi, I am trying to place some floats in the margin and noticed that the caption gets centered instead of following my specification to flushleft. If the float is in the main body it is ok. . I have a small example below. I tested with 2015.04.18 14:41. Is there a way to fix the alignment? Thanks, Brian \setuppapersize[letter,portrait][letter,portrait] \setupcaption[figure][location=top,align={flushleft}] \showframe \starttext \setuplayout[backspace=2.75in,leftmargin=2.25in,rightmargin=0.5in,cutspace=0.5in,location=middle,width=middle,margindistance=0.00in] \placefigure[inleft,hanging]{My Title}{\framed[width=2.75in,height=1.0in]{!}} \placefigure[here,hanging]{My Title}{\framed[width=2.75in,height=1.0in]{!}} \placefigure[inright,hanging]{My Title}{\framed[width=2.75in,height=1.0in]{!}} \stoptext

\lfloor, \rfloor, \lceil, \rceil vanish with \big, \Big, \bigg, \Bigg and their left and right variants

Mr Hagen, is it the expected behaviour? \starttext The delimiters are correctly displayed: \startformula \left\lfloor \frac{x}{y}\right\rfloor \stopformula The delimiters vanish: \startformula \Bigl\lfloor \frac{x}{y}\Bigr\rfloor \stopformula \stoptext Maggyero

ConTeXt equivalent of \newmcodes@
by Maggyero 27 Apr '15

27 Apr '15

> \definemathcommand[xyz][nolop]{\text{fancy-function-name'*.:}} The problem with this solution is that the font of the operator becomes the normal text font whereas I want to use the standard math upright font (so \mfunction + \kern\zeropoint + \newmathcodes is the way to go). For instance with \setupbodyfont[sansserif] the operator name becomes sans serif, which I don't want. I only need to make this code compile: \begingroup \catcode`\"=12 \gdef\newmcodes@{\mathcode`\'39\mathcode`\*42\mathcode`\."613A% \ifnum\mathcode`\-=45 \else \mathchardef\std at minus\mathcode`\-\relax \fi \mathcode`\-45\mathcode`\/47\mathcode`\:"603A\relax} \endgroup \definemathcommand[xyz][nolop]{\newmcodes@ \kern\zeropoint\mfunction{fancy-function-name'*.:}} \starttext \xyz \stoptext How can I do that? The compilation fails at the \ifnum condition. Isn't \ifnum a ConTeXt macro? Maggyero

ConTeXt equivalent of \newmcodes@
by Maggyero 27 Apr '15

27 Apr '15

> Does \definemathcommand [xyz] [nolop] {xyz} do what you want? Not really if, instead of xyz, I want a name with hyphens, quotes, stars or colons. Compare the output of \definemathcommand[xyz][nolop]{fancy-function-name'*.:} in ConTeXt with the output of \DeclareMathOperator{\xyz}{fancy-function-name'*.:} in LaTeX. What I can do is \definemathcommand[xyz][nolop]{\kern\zeropoint\mfunction{fancy-function-name'*.:}} which gives the same result as \DeclareMathOperator, except for the hyphens and the star are converted into binary operators and the colon which is preceded by a space, since I didn't use \newmcodes@, that is why I asked how to implement the macro \newmcodes@ in ConTeXt, which is defined in LaTeX as \begingroup \catcode`\"=12 \gdef\newmcodes@{\mathcode`\'39\mathcode`\*42\mathcode`\."613A% \ifnum\mathcode`\-=45 \else \mathchardef\std at minus\mathcode`\-\relax \fi \mathcode`\-45\mathcode`\/47\mathcode`\:"603A\relax} \endgroup so that the following code can compile in ConTeXt: \definemathcommand[xyz][nolop]{\newmcodes@ \kern\zeropoint\mfunction{fancy-function-name'*.:}} Maggyero

ConTeXt equivalent of \newmcodes@
by Maggyero 27 Apr '15

27 Apr '15

> do you have an example of usage Yes, I am trying to create the command \operatorname in ConTeXt. I know that in LaTeX \operatorname{xyz} is equivalent to \mathop{\newmcodes@\kern\z@\operator@font xyz}\csname nolimits@\endcsname} according to the AMSopn package ( http://www.bakoma-tex.com/doc/latex/amsmath/amsopn.pdf) and I am trying to translates that in ConTeXt: \mathop{\newmcodes@\kern\zeropoint\mfunction{xyz}}\nolimits but \newmcodes@ produces an error. In LaTeX, \newmcodes@ is defined as \begingroup \catcode`\"=12 \gdef\newmcodes@{\mathcode`\'39\mathcode`\*42\mathcode`\."613A% \ifnum\mathcode`\-=45 \else \mathchardef\std@minus\mathcode`\-\relax \fi \mathcode`\-45\mathcode`\/47\mathcode`\:"603A\relax} \endgroup according to the AMSopn package, so I have copied the code in my document (I only removed the @ so that I don't have to convert its catcode) but the if condition gives an error (however it compiles fine without the if condition). I also know that there is the ConTeXt command \definemathcommand[nolop]{xyz} which I thought stands as an equivalent to the \operatorname wrapper \DeclareMathOperator, but apparently not since it doe not use the 3 commands 1. \newmcodes@ 2. \kern\z@ 3. \operator@font in it, so I wonder the point of such a wrapper since all it seems it does is translates to \mathop{xyz}\nolimits To sum up, I would like to have a \DeclareMathOperator in ConTeXt, so here are my 2 questions: 1. What is the ConTeXt equivalent of \newmcodes@? 2. What is the point of \definemathcommand? Maggyero

Changing coversion of formulas
by Aditya Mahajan 27 Apr '15

Hi, How does one change the numberconversion for math formulas? The old method: \setupformulas[numberconversion=set 1] \starttext \placeformula \startformula E = mc^2 \stopformula \stoptext does not appear to work. Thanks, Aditya

ConTeXt equivalent of \newmcodes@
by Maggyero 27 Apr '15

27 Apr '15

Dear list members, What is the ConTeXt equivalent of the LaTeX function \newmcodes@ defined in the AMSopn package (this function is used inside \DeclareMathOperator and \operatorname and has the effect of resetting text-mode punctuation characters such as *, -, /, :, and ’ in operator names)? Thank you in advance.
