caption alignment with floats in the margin
by Brian R. Landy 27 Apr '15

27 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

> \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

> 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

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.

Problem with margin figures and whitespace in text
by Rik Kabel 26 Apr '15

26 Apr '15

I have two problems with figures placed into the left or right margin. When the figure is in a group, extra whitespace is inserted between the paragraphs that precede and follow the placefigure command. This happens for figures placed by startplacefigure/stopplacefigure and tradiitonal placefigure commands, and paragraphs placed by startparagraph/stopparagraph or marked by par or newlines. When the figure is not in a group, whitespace called for by \setupwhitespace is lost, except when the paragraphs are marked by traditional means. That is, whitespace is lost when startparagraph/stopparagraph is used. Interestingly, when that is changed to bpar/epar, the problem for ungrouped figures disappears, but as I understand it, bpar/epar is not a real substitute for startparagraph/stopparagraph. There is probably a simple explanation, but it eludes me. I prefer to be able to use startparagraph/stopparagraph, and it is sometimes desirable to place a figure into a group in order to prevent unique settings from leaking out. The following should demonstrate the problem. Turning on grid setting makes it worse. I get the same result with current betas and older versions. \useMPlibrary [dum] %\showgrid \setuplayout [%grid=yes, backspace=151pt,leftmargin=117pt] \setupwhitespace[big] \define\Paragraph{\startparagraph\input khatt-en\stopparagraph} \starttext { \subject{Start/stop paragraphs and figures} \subsubject{Group, extra whitespace} \Paragraph \Paragraph \begingroup \startplacefigure[location={leftmargin,none}] \externalfigure[A] \stopplacefigure \endgroup \Paragraph \Paragraph \subsubject{No group, no whitespace} \Paragraph \Paragraph \startplacefigure[location={leftmargin,none}] \externalfigure[A] \stopplacefigure \Paragraph \Paragraph \Paragraph } \page { \subject{Start/stop paragraphs, traditional figures} \subsubject{Group, extra whitespace} \Paragraph \Paragraph {\placefigure[leftmargin,none]{}{\externalfigure[A]}} \Paragraph \Paragraph \subsubject{No group, no whitespace} \Paragraph \Paragraph \placefigure[leftmargin,none]{}{\externalfigure[A]} \Paragraph \Paragraph \Paragraph } \page { \subject{Traditional paragraphs, start/stop figures} \subsubject{Group, extra whitespace} \input khatt-en\par \input khatt-en\par \begingroup% or \bgroup or { \startplacefigure[location={leftmargin,none}] \externalfigure[A] \stopplacefigure \endgroup% or \egroup or } \input khatt-en\par \input khatt-en\par \subsubject{Okay} \input khatt-en\par \input khatt-en\par \startplacefigure[location={leftmargin,none}] \externalfigure[A] \stopplacefigure \input khatt-en\par \input khatt-en\par \input khatt-en\par } \page { \subject{Traditional paragraphs, traditional figures} \subsubject{Group, extra whitespace} \input khatt-en\par \input khatt-en\par {\placefigure[leftmargin,none]{}{\externalfigure[A]}} \input khatt-en\par \input khatt-en\par \subsubject{Okay} \input khatt-en\par \input khatt-en\par \placefigure[leftmargin,none]{}{\externalfigure[A]} \input khatt-en\par \input khatt-en\par \input khatt-en\par } \stoptext -- Rik

adding extra space before section blocks in the TOC
by Pablo Rodriguez 26 Apr '15

26 Apr '15

Dear list, I have the following sample: \starttext \completecontent \startfrontmatter \chapter{Foreword} \chapter{Introduction} \stopfrontmatter \startbodymatter \chapter{First Chapter} \chapter{Second Chapter} \chapter{Third Chapter} \stopbodymatter \startbackmatter \chapter{Conclusions} \chapter{Notes} \stopbackmatter \startappendices \chapter{Appendix One} \chapter{Appendix Two} \stopappendices \stoptext How could I add some extra space in the TOC before each section block? I mean, a visual separation before “First Chapter”, “Conclusions” and “Appendix One” in \completecontent. Many thanks for your help, Pablo -- http://www.ousia.tk
