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

I now I could use a table to do this but I should also be able to do this with \framed and \startcombination[ cos * rows ]] But no matter what order I give to [ n x c ] the result is always a vertical split and not a horizontal one.

testing 32bit and 64bit versions in Win7 64bit

26 Apr '15

Dear list, I have the following sample: \starttext \dorecurse{10}{ \dorecurse{10}{ \dorecurse{10}{ \dorecurse{10}{ \input zapf\par}}}} \stoptext I used it to test compilation speed from both 32bit and 64bit. The machine has an Intel(R) Core(TM) i5-4440 CPU @ 3.10GHz processor with 8GB RAM running Win7 64bit. Compiling both with luajittex and --purgeall (more than once), sample results are: 2015.04.16 15:14 (32bit) - 153.959 seconds 2015.04.16 15:14 (64bit) - 154.908 seconds Shouldn’t the 64bit version be much faster or am I missing something?

Feature request for export: Interactive Notes
by Idris Samawi Hamid ادريس سماوي حامد 25 Apr '15

25 Apr '15

Dear gang, I've spent a considerable amount of time over the past month trying to master the art of xhtml output. We are close to being able to use ConTeXt as a replacement for markdown in, e.g., WordPress. Indeed, I plan to present the results of this experiment (porting an entire academic article to xhtml and WP) in a future article for one of the TeX journals... There is at least one crucial feature that's still needed. Perhaps it is already supported: If so, it would be much appreciated if someone kindly explained how to do it. In a web post (or epub), one wants to be able to interact back and forth with notes. Here is how markdown (extra) does it: ========Input======== That's some text with a footnote.[^1] [^1]: And that's the footnote. That's the second paragraph of the note. More main text ========Output======== <p>That's some text with a footnote.<sup id="fnref:1"><a href="#fn:1" rel="footnote">1</a></sup></p> <p>More main text</p> <div class="footnotes"> <hr /> <ol> <li id="fn:1"> <p>And that's the footnote.</p> <p>That's the second paragraph of the note. <a href="#fnref:1" rev="footnote">↩</a></p> </li> </ol> </div> ===================== The resulting html file is attached. '↩' corresponds to U+21A9 (↩). See also https://michelf.ca/projects/php-markdown/extra/#footnotes Now we can of course already export xhtml footnotes from ConTeXt but there will be no interactive links. In the current project, there are 77 footnotes; I had to add the links manually to get the output to do what we wanted. [Also note that it makes much more sense to export the footnotes as endnotes, particularly for long blog posts.] Is there already a way to get done automatically? In any case: This feature is a must-do in my humble opinion. Aside from a few other export bugs, this is one of the few features still needed so that ConTeXt can completely replace markdown for (advanced) web posts. Thanks is advance and Best wishes Idris -- Idris Samawi Hamid, Professor Department of Philosophy Colorado State University Fort Collins, CO 80523

Unable to resave float
by Aditya Mahajan 25 Apr '15

25 Apr '15

I have a complex document, where I use \startbackground .... \startplacefigure[location={always,none}] ... \stopplacefigure ... \stopbackground (This is for exam solutions and the background is supposed to be a frame around the solution; the figure is a figure included in the solution). Occasionally, some of the floats are not placed in the output. For example $grep float filename.log gives: floatblocks > '1' placed floatblocks > '2' placed floatblocks > '3' placed floatblocks > order disturbed structure > floats > unable to resave float floatblocks > '5' placed floatblocks > '6' placed floatblocks > order disturbed structure > floats > unable to resave float floatblocks > '8' placed So, float 4 and 7 were not saved. It is bit tricky to create a minimal example, but any idea how I can prevent this. I am using version 2015.04.03 Thanks, Aditya

Export bugs

Dear gang, Here are two export bugs, full test suite attached: ==========sh_ahmad-qajar-xml-test-highlight.tex=========== \setupexport[cssfile=sh_ahmad-qajar.css] \setupbackend[export=yes] \definehighlight[emphasis][style=\em] \definehighlight[important][style=bold] \starttext \startparagraph Some \emph{emphasis} and \important{important}. \emph{Emphasis} and \important{important}. \stopparagraph \stoptext ==========sh_ahmad-qajar-xml-test-highlight-div.xhtml========== <div> <div class="paragraph">Some emphasis and <div class="highlight important">important</div>. <div class="break"></div> Emphasis <div class="break"></div> and <div class="highlight important">important</div>.</div> </div> ========== The exported formatting of \emph vanishes in each instance, as well as misbehaves in the second case; \important behaves just fine. It seems the export doesn't like \em. Can this be fixed? Thanks and Best wishes Idris -- Idris Samawi Hamid, Professor Department of Philosophy Colorado State University Fort Collins, CO 80523

\lfloor, \rfloor, \lceil, \rceil vanish with \big, \Big, \bigg, \Bigg and their left and right variants
by Maggyero 25 Apr '15

25 Apr '15

Dear NTG-ConTeXt members, The math delimiters for floor and ceiling functions (\lfloor, \rfloor, \lceil, \rceil) work with the automatic scaling commands (\left and \right) but vanish with the manual scaling commands (\big, \Big, \bigg, \Bigg, \bigl, \Bigl, \biggl, \Biggl, \bigr, \Bigr, \biggr, \Biggr). Do I use the right commands? Or could the developers fix that? Thank you in advance. Maggyero

how to insert symbols into document?
by Csikos Bela 23 Apr '15

23 Apr '15

Hello context users: I would like to insert symbols into my document, especially black-diamond and losenge symbols. I read symbols page at contextgarden but still don't know how to do it. I also tried \showsymbolset[was] etc but the symbols but I did not find these (and many other symbols either) in the output pages. I found that symb-imp-mis.mkiv file defines this symbol (line 49) but I don't know how to make it show. Do I have to load specific symbol fonts? If yes how can I find out which font has the given symbols? What I tried so far included: % begin code \usesymbols[imp-mis] \starttext ◆ \blackdiamond \symbol [blackdiamond] % end code None of these show anything. Thanks in advance, bcsikos

Dear list, I have downloaded the ConTeXt Suite (beta from 2015.04.14 18:48)for Win32 and Win64 in my Linux box using: sh ./first-setup.sh --platform=windows --modules=all sh ./first-setup.sh --platform=win64 --modules=all But when I try to run them, I experience the following issues: With the Win32 version, mtxrunjit is found by Windows 7, but contextjit cannot be found. The binary is in its proper path. Withe the Win64 version, contextjit is found, but mtxrunjit cannot be found. In this case, I need to run "mtxrunjit --generate" first, because invoking contextjit gives the following error: mtxrun | unknown script 'context.lua' or 'mtx-context.lua' Why are some binaries found by Windows and others not?

vertical spacing and makeups

Shouldn’t white space be added only between paragraphs? The second page is right vertically centered. And the third page shows that the white space isn’t added before the first paragraph in a normal page (no makeup). This is the first issue, isn’t it a bug? Or what am I missing? The second issue is about the line height. If I didn’t get it wrong from Hans some days ago, line height is the x-height, plus ascender and descender heights. In vertical centering for makeups, why does ascender or descender height affect to basline position? Sorry, but this is a problem for readability. And it think it is better to center the line instead than a group of glyphs. Or am I missing something in this second issue too? Many thanks for your help, Pablo -- http://www.ousia.tk

It took me a while to make your code operational in the way I need it. For the new example you gave is still an "integral file". My project, like most book-projects, I guess, is modular with a master file Project.tex, into which everything else, setups, .bbl's, front- and backmatter, the various chapters are input. Though strictly speaking it would not be impossible to add some 1000 lines of index entries before \startproject, it would not be especially handy, and I cannot believe that it would be the proper ConTeXt-way to do it. I found that when I split your code, transferred the top part to a new file, which I named "IndexItems", and input that into the other half, the text proper, it works. But when I add another file with indexentries, for instance "indexitemsnames", then only one of them, the one at the top is used. So it seems that the whole collection of index items must be in one file. Is that the only possibility or are there ways to enable the use of several collections of index items? Best regards, Robert
