Dear Otared, What do you mean “does not typeset correctly as expected”? I copied and tested the last example and got the result without error. One problem is that the vertical alignment is not centered as the example of Aditya’s. Would you please tell me what I miss? Thank you. Best regards, Dalyoung > > I wanted to make an observation about the last example in that page, which does not typeset correctly as expected, and also it does not work well if one wanted to make a multiplication table instead of the addition table of your examples. I think the following modification might be necessary (here for the multiplication table): >

Which color model shall I use
by Jan U. Hasecke 01 Oct '18

01 Oct '18

Hi, I would like to know, how to define colors to have a good printing quality. I am currently producing print materials for a company where all colors were defined for online usage first, so we started with defining RGB colors and then derived CMYK colors. What is the best approach for defining colors in print materials? What color model shall I use? RGB or CMYK? For the background. We have some SVG graphics we use on the website. They are defined in RGB color model. And we use them in the print materials as well. I tend to define RGB colors in my print documents so that the colors of the included SVG files match the defined colors I use elsewhere in the document. Eg. the Corporate-Blue of the Logo (SVG) will match the Blue of the headlines. I could as well define CMYK colors in the document but then I have two different color models in one document and I fear that the colors are printed in different hues. What would you do? TIA juh

Questions and observations on the div html export
by Rik 01 Oct '18

01 Oct '18

List, I have been wrestling with the div.html output produced by the export back end, and have a few questions. On the list, Hans has suggested defining elements with two commands, as: \setelementbackendtag [BlockItem] \setelementnature [BlockItem][display] \setelementbackendtag [InlineItem] \setelementnature [InlineItem][inline] These commands do not appear on the wiki or in i-context.pdf. In i-context.pdf, we find: 1 2 3 \setelementexporttag [...][...][...] OPT 1 NAME 2_export_ nature pdf 3 inline display mixed I have tried this latter command in many variations, and cannot understand just how to use it. For example, both of these: \setelementexporttag[BlockItem][display] \setelementexporttag[BlockItem][export][display] generate divs with class="display", when one wants class="BlockItem". But the pair \setelementbackendtag and \setelementnature works for that. Is there any documentation for any of these commands, beyond the syntax in i-convert for \setelementexporttag? The \startelement command takes one or two arguments. The first is the element name, and is required. What is the intended use of the second argument, a list of key/value pairs? Nothing seems to be passed via the back end to the div.html (or raw.xml) file. Next, the back end generates div elements for both block and inline scopes, while html calls for span elements as inline containers. Defined highlights, which are by nature inline containers, are also translated to divs instead of spans. The generated css does identify the divs with display: block and display: inline as appropriate, but that does not help with tools that work with html. (HTML Tidy, for example, will happily introduce extra whitespace because it inserts a newline before a div that should really be a span.) Finally, what is meant by mixed (with respect to inline and display)? If anyone else has figured out some of this stuff, please send some pointers. -- Rik

tagged elements in tables (TABLE, tabulate, xtable)
by Rik Kabel 30 Sep '18

30 Sep '18

List, I am trying to use tables in an export with tagging to support CSS styling for eventual ebook production (with the added hope that cross-references and perhaps indexing someday might be supported). I have run into an odd limitation. It seems that only tagged element may not be present in a table. The primary use is to manage text in sidebars (first or last column, moved by CSS to the correct position, for a two- or three-column one-row table). * When there are three tagged (or more) elements in the table, the table is not present in the resulting html export, nor is much of the document following it, and the file is not well-formed. * When there are two tagged elements in the table, the resulting html export is without part of the document following the table and is not well-formed (even though the table appears complete with the tag divs). * When there is only one tagged element in the table, the resulting html export appears to include the complete document but is still not well-formed. * When there are none, all is well, except that there is nothing to which I can associate the needed CSS. * In all cases, the pdf output is correct, but the pdf is a throw-away when generating html exports. It looks like tagged elements are not currently supported within tables. I had thought of putting the table into a tagged element and using nth-child selectors to apply CSS to cells by column, but that is finicky and it does not offer the flexibility that tagged elements provide. Can anyone suggest another alternative? Example follows. As supplied, no tagged elements are generated and all is well. Uncomment either the start/stop element lines in the table to get one tagged element in the output, or the getbuffer line to get two (or all to get three, or...). There are similar problems with tabulate and xtables, but only TABLE is shown here. \setupstructure [state=start, method=auto] \setuptagging [state=start] \setupbackend [export=yes] \setupexport [title={Test Example}] \setelementbackendtag [Block] \setelementnature [Block][display] \setelementbackendtag [Column] \setelementnature [Column][display] \setelementbackendtag [Text] \setelementnature [Text][display] \define\DummyText{Lorem ipsum dolor sit amet, \ldots} \startbuffer[Demo] \startelement[Block] \startelement[Text] \DummyText \DummyText \DummyText \DummyText \stopelement \stopelement \stopbuffer \starttext \startchapter[title={One}] \startsection[title={OneDotOne}] \bTABLE \bTR \bTD % \startelement[Column]% adds 1 tagged elements \DummyText \DummyText % \getbuffer[Demo]% adds 2 tagged elements % \stopelement \eTD \bTD \DummyText \DummyText \eTD \eTR \eTABLE \stopsection% \startsection[title={OneDotTwo}] \startparagraph \DummyText \stopparagraph \stopsection \stopchapter \stoptext -- Rik

remapper change in luatex-basics-gen.lua
by Ulrike Fischer 30 Sep '18

30 Sep '18

in luatex-basics-gen.lua the remapper maps lua to "tex": local remapper = { otf = "opentype fonts", ttf = "truetype fonts", ttc = "truetype fonts", cid = "cid maps", cidmap = "cid maps", -- fea = "font feature files", -- no longer supported pfb = "type1 fonts", -- needed for vector loading afm = "afm", enc = "enc files", lua = "tex", --<<<<<<<change } This is new compared to the state in 2/2017 The remapper is then used in resolvers.findfile. The change has been imported in latex with the new luaotfload and now broke the function "pgf_lookup_and_require" in the pgf graphdrawing library which in its code uses resolvers.findfile -- probably so that it works also as context library (http://minimals.contextgarden.net/current/modules/t-tikz/tex/generic/pgf/gr…) Due to the mapping of lua to the tex type resolvers.findfile("layered","lua") no longer finds layered.lua. Apart from telling the pgf people not to use resolvers.findfile like this when latex is used, is there anything one could do in the generic fontloader? -- Ulrike Fischer https://www.troubleshooting-tex.de/

align is reversed inside a table
by David Walther 30 Sep '18

30 Sep '18

Using this table as an example, when I do align=left, the column aligns right, and when I do align=right, it aligns left. align=center works as expected. Am I doing something wrong or is this a bug? I am using the version of context distributed with Debian unstable: mtx-context | ConTeXt Process Management 1.01 mtx-context | mtx-context | main context file: /usr/share/texmf/tex/context/base/mkiv/context.mkiv mtx-context | current version: 2017.05.15 21:48 Minimal example here: \setuppagenumbering[alternative=doublesided,location=none,page=no] \setupfootertexts[\sans{Source: http://mywebsite}] \setupheadertexts[test column text wrapping] \setupheadertexts [] [Page \userpagenumber\ of \lastuserpagenumber] [Page \userpagenumber\ of \lastuserpagenumber] [] \setuppapersize[letter, portrait] \setuplayout[topspace=0.5in, backspace=1in, height=10in, width=7in, header=0.5in, footer=0.5in, headerdistance=0in, footerdistance=0in] \switchtobodyfont[12pt] \starttext \setupTABLE[split=repeat] \setupTABLE[r][each][toffset=3pt, boffset=3pt, loffset=3pt, roffset=3pt] \setupTABLE[c][each][leftframe=off,rightframe=off,align=right] \setupTABLE[c][first][frame=off,align=left] \setupTABLE[c][2][style=\tfx\it,align=left] \bTABLE \bTABLEhead \bTR\bTH Col1 \eTH\bTH Col2 \eTH\bTH Col3 \eTH\eTR \eTABLEhead \bTABLEnext \bTR\bTH Col1 \eTH\bTH Col2 \eTH\bTH Col3 \eTH\eTR \eTABLEnext \bTABLEbody \bTR\bTC \eTC\bTC NightShift \eTC\bTC Tension Lines 146 - 150 \eTC\eTR \bTR\bTC 30. \eTC \bTC[nc=2,align=center,style=] \bf{Foo Bar} \eTC\eTR %\bTR\bTC 30. \eTC \bTC\eTC \bTC[align=center] \bf{Foo Bar} \eTC\eTR \eTABLEbody \eTABLE \stoptext

setupitemize (no hanging)
by Alan Braslau 30 Sep '18

30 Sep '18

Silly question: How do I setup itemize so that there be no hanging indent and the symbol is aligned with the left edge of the text, i.e. not in the margin? (margin or inmargin or width=-2em puts the symbol in the margin.) Alan

open type feature "frac"
by Ulrike Fischer 29 Sep '18

29 Sep '18

Due to a question on tex.sx (https://tex.stackexchange.com/questions/452969/luatex-fontfeaturefractions-…) I looked again (see https://www.mail-archive.com/ntg-context@ntg.nl/msg84822.html) at the frac feature. The output is still not really satisfactory. With mode=node numbers with slash looks okay, but single numbers are rather odd: only the last digit has the correct size: \starttext \font\test={file:linlibertine_r.otf:mode=node;script=latn;language=DFLT;+frac} \test 787347 125 1/7 1/2 3/4 5/6 7/8 9/10 11/12 31415/27182 1000/1000000 \font\test={file:linlibertine_r.otf:mode=base;script=latn;language=DFLT;+frac} \test 787347 125 1/7 1/2 3/4 5/6 7/8 9/10 11/12 31415/27182 1000/1000000 \stoptext (It could be a font bug, the output with xetex isn't good either). -- Ulrike Fischer https://www.troubleshooting-tex.de/
