Re: [NTG-context] Problem with math alignment

Dear Otared, Thank you for checking my code. > The strange fact is that if one puts > \startitem $\overline{A} = A$ \stopitem > as the first item in your example (instead of the second), then ConTeXt creates three columns, with the first item the result of the above line, and then items 2 and 3 in the second column and finally item 4 in the third column. Despite this the textwidth is divided into four… > I have noticed before what you described. If there are 8 items, the outputs are all different depends on the location of \overline. I couldn’t see any pattern in the output. The only thing I can see is that the command ‘\overline’ makes a blank line, and I just guess that it is related with the column environment. > I hope Hans will see your message and fix the issue. Yes, it is also my hope. And, I believe that he also solve the alignment problem too. Best regards, Dalyoung

The alignment is done at the begin and end of the cell content (look at the commented commands below): \unexpanded\def\math_matrix_start_cell {\dostarttagged\t!mathtablecell\empty \hss %\math_left_of_equalign \startimath \math_matrix_set_style \tabskip\zeropoint \everycr\emptytoks} \unexpanded\def\math_matrix_stop_cell {\stopimath %\math_right_of_eqalign \hss \dostoptagged} Wolfgang

Dear Otared, I run your code and found that they are not aligned properly as you want. But I don’t know how to do for the correct alignment. Did you see the mail about the \overline problem in column environment which I listed recently? It is a different problem from yours, but I’d like to know whether you got the same output as mine or not. Would you please check it in your computer? Thank you. Best regards, Dalyoung

Problem with math alignment
by Otared Kavian 13 Nov '17

13 Nov '17

Hi everybody, Does anyone have noticed that the mathalignment has changed its behaviour recently? I think a bug has managed to enter the environment which handles the mathalignment, at least since a few weeks ago. I did not report it earlier because I was traveling and did not have a stable internet access. Here is a minimal example where on can see in the first displayed formula that the first and third column are centered while the first one shoud be right-aligned and the third one left-aligned. (Actually it seems that all columns are centered…) %%% begin pb-math-align.tex \definemathmatrix[alignedcases] [align={right,left,left}, distance=3pt, left={\left\{}, right={\right.}, style=\displaystyle] \starttext \startformula \startalignedcases \NC \partial_{tt} u - \Delta u + q(x) u \NC = 0 \NC \quad\mbox{in }\;(0,T)\times\Omega \NR \NC u(0,x) \NC = 0 \NC \quad \mbox{in }\; \Omega \NR \NC \partial_{t} u(0,x) \NC = 0 \NC \quad \mbox{in }\; \Omega \NR \NC {\partial u \over\partial{\bf n} } \NC = g(t,\sigma) \NC \quad \mbox{on }\; (0,T)\times\partial\Omega. \NR \stopalignedcases \stopformula \startformula \startalignedcases \NC \partial_{tt} u - \Delta u + q(x) u \NC = 0 \NC \quad\mbox{in }\; (0,T)\times\Omega \NR \NC - \Delta v \NC = q(x) \partial_{t}u \NC \quad\mbox{in }\; \Omega \NR \stopalignedcases \stopformula \stoptext %%% end pb-math-align.tex

problems with XML export
by Henning Hraban Ramm 12 Nov '17

12 Nov '17

Here are a few problems that I encountered in my current ePub projects: * \color[]{} leaves no trace in export. * As soon as I activate export, my PDFs get two pages more, i.e. page breaking changes somehow, I didn’t yet track how. * For quotability, I’d like to set markers in my HTML, where the print version has page breaks. But the exported XML doesn’t contain anything like that. Is it possible to add? * Some spacing like \, gets lost. I’m sure there’s an appropriate Unicode glyph. Would it be possible to add that? * Errors in exported XML: (1) <registerentry> <registercontent>Brecht, Bertolt</registercontent> <registerpages><registerpage><link destination="internal(358)" location="358" prefix="c_anhang">53</link></registerpage><registerseparator>,</registerseparator><registerpagerange>–</registerpagerange><registerseparator>,</registerseparator><registerpage><link destination="internal(635)" location="635" prefix="c_anhang">88</link></registerpage></registerpages> </registerentry> Here we have a register entry with (only) a page range. There should be no <registerseparator> (it’s unneccessarily complicated to filter that out if there’s also a <registerpagerange>). I.e. text content has ",–," instead of just "–". (2) \def\SC#1{\dostarttagged{highlight}{scaps}{\sc\lowercase{#1}}\dostoptagged} \starttabulate[|lw(1cm)|p|] \NC AFG\NC \SC{SED}, Akademie für Gesellschaftswissenschaften, Schriftenverzeichnis\NC\NR \NC BER\crlf\color[white]{dummy}\NC Hochschule der Deutschen Gewerkschaften \quotation{Fritz Heckert} in Bernau, Schriftenverzeichnis\NC\NR \stoptabulate leads to <tabulate> <tabulaterow> <tabulatecell align="flushleft">AFG</tabulatecell> <break/> <highlight detail="scaps"><tabulatecell>sed</tabulatecell>, Akademie für Gesellschaftswissenschaften, Schriftenverzeichnis</highlight> </tabulaterow> <tabulaterow> <tabulatecell align="flushleft">BERdummy</tabulatecell> <tabulatecell>Hochschule der Deutschen Gewerkschaften <delimited detail="quotation-1"><delimitedsymbol symbol="left">»</delimitedsymbol><delimitedcontent>Fritz Heckert</delimitedcontent><delimitedsymbol symbol="right">«</delimitedsymbol></delimited> in Bernau, Schriftenverzeichnis</tabulatecell> </tabulaterow> </tabulate> - <break /> is nonsense - <highlight> breaks <tabulatecell> (maybe my \SC definition is bad, but nobody answered to my according question) Greetlings, Hraban --- http://www.fiee.net http://wiki.contextgarden.net GPG Key ID 1C9B22FD

new module seeking approval: handlecsv
by Pablo Rodriguez 12 Nov '17

12 Nov '17

Dear Mojca, I have submitted the handlecsv module to https://modules.contextgarden.net/cgi-bin/module.cgi/action=view/id=86. It can handle different .csv files to data merging for document automatic generation. Would it be possible that it could be included in the ConTeXt Suite? Many thanks for your help, Pablo PS: many kudos to Taco for solving the issue with the certificate. -- http://www.ousia.tk

Reproducible PDF output
by N. Raghavendra 12 Nov '17

12 Nov '17

I would like to have reproducible PDF output from ConTeXt documents. I tried the suggestions at https://tex.stackexchange.com/a/313605/146025 but they did not work. The PDF output has information like "ConTeXt.Time", "CreateDate", etc., which depend on the time the source was processed at. How do I suppress such temporal information, that is not supplied by the author, from the PDF output? Here are my two attempts: ---------------------------------------------------------------------- $ cat example.tex \pdfinfoomitdate=1 \pdftrailerid{} \starttext Hello, world! \stoptext $ ( context example.tex && cp example.pdf a && sleep 1 && \ context example.tex && cp example.pdf b ) > /dev/null && \ md5sum a b 6a4ac7122bb502062e7ea87be52df166 a cac1ab3160003526e49da135d77e4eda b ---------------------------------------------------------------------- ---------------------------------------------------------------------- $ cat example.tex \pdfvariable suppressoptionalinfo \numexpr 0 + 1 % PTEX.FullBanner + 2 % PTEX.FileName + 4 % PTEX.PageNumber + 8 % PTEX.InfoDict + 16 % Creator + 32 % CreationDate + 64 % ModDate + 128 % Producer + 256 % Trapped + 512 % ID \relax \starttext Hello, world! \stoptext $ ( context example.tex && cp example.pdf a && sleep 1 && \ context example.tex && cp example.pdf b ) > /dev/null && \ md5sum a b 2116aeec2b5bed2bfd02d16332700758 a 3204a1a127f139da8d960037a8ba0690 b ---------------------------------------------------------------------- Here is the reason I want reproducible builds. I keep the source of my ConTeXt documents under version control. I also keep their PDF output under version control because I often find, several years after a document was written, that I don't have the supporting files needed to process it; in such a case, until I get the missing supporting files, I can at least view the PDF output. Now, even when the source has not changed, if I run context on it, the PDF output changes, and the version control system reports the PDF file as modified. In such a situation, I have to register the change in the version control system, or revert the PDF file to its version. I would like to avoid this extra work. Thanks and regards, Raghu. -- N.

insert tags in export xml
by Henning Hraban Ramm 12 Nov '17

12 Nov '17

Ahoi, I’m working on ePubs again and need a bit more information in the exported xml. E.g. I defined my own small caps macro: \def\SC#1{{\sc\lowercase{#1}}} to be able to say \SC{ISO} instead of changing everything into lowercase like {\sc iso}. (I also tried OpenType features, but those were too unreliable with my fonts. That’s not the problem here.) But my small caps end as unmarked lowercase in the exported xml. I didn’t manage to combine my above approach with \definehighlight, but after poking around in the source (core-sys.mkiv, strc-tag.mkiv) I found this solution: \def\SC#1{\dostarttagged{highlight}{scaps}{\sc\lowercase{#1}}\dostoptagged} so that \SC{ISO} becomes <highlight detail="scaps">iso</highlight> Works for me. Better suggestions? Greetlings, Hraban --- http://www.fiee.net http://wiki.contextgarden.net GPG Key ID 1C9B22FD

Ancient Egyptian Representation
by Brian Ballsun-Stanton 10 Nov '17

10 Nov '17

Hi Folks, I'm trying to figure out ways of representing: Using computer-intelligable output. This (if you have a font supporting ancient egyptian installed): 𓄂 𓂝 𓈖 𓁷 𓂋 𓇋 𓅭 𓊵 𓃝 𓏏 𓊪 𓁹 𓈖 𓈎 𓅡 𓏏 𓇋 is an awful attempt at same using google docs tables inside tables, but should have the virtue of being interactable-with. The characters themselves are part of the ancient egpytian block and have font support (noto by google) The problem is in composition. There's: Above/below (that first "character" is composed of two), overlapping (that bull-thing with bits), mirrored, right-to-left and left-to-right, as well as vertical text. While these characters can be laid out in jsesh or equivalent, the output is of an *image* instead of something which can be well-represented (much-less copied and pasted). As one of the routes of exploration, since I do quite a lot of work in ConTeXt, I'm wondering what ... modes.... one would need to be in to even start thinking about placement here. (I'm avoiding simply placing graphics objects by hand as that defeats the purpose). I suppose my question is: is it worth trying to coerce ConTeXt into working with this, or do I need to investigate a different *sort* of tool entirely? (probably a purpose-built xml parser or something in that vein). Cheers, -Brian

\overline problem again.
by Jeong Dal 09 Nov '17

09 Nov '17

Hi, Yesterday, I had a weird output of the following sample code. \overline changes the baseline when it is used in the column environment. It works fine if it is used without columns. I had similar problems long time ago and I thought it was fixed at that time. Please check the following sample. Best regards, Dalyoung %%%%%%%%%%%%%%%%% \starttext \startitemize[n] \item Here is a line of math formulas: $\overline{A} = A$, $A' \subset A$, $A \cap A' = \emptyset$ and $A^c$ is open. \item list items one by one in a new line \startitemize[n, packed, broad][stopper=,left=(, right=)] \item {$A' \subset A$} \item {$A \cap A' = \emptyset$} \item {$A^c$ is open} \item {$\overline{A} = A$} \stopitemize \stopitemize As you see, there is no problem al all.\par But if we list the same formulas using columns, then there is a baseline problem. \startitemize[continue] \item list items in 4 columns \startitemize[n, packed,columns, four, broad][stopper=,left=(, right=)] \item {$A' \subset A$} \item {$\overline{A} = A$} \item {$A \cap A' = \emptyset$} \item {$A^c$ is open} \stopitemize \item list items in 2 columns \startitemize[n, packed,columns, two, broad][stopper=,left=(, right=)] \item {$\overline{\{a\}} = \{a\}$} \item {$\overline{\{b\}} = \{b,e\}$} \item {$\overline{\{c\}} = \{b,c,d\}$} \item {$\overline{\{d\}} = \{b,c,d,e\}$} \stopitemize \stopitemize \stoptext %%%%%%%%%%%%%%%
