Hi, Is it possible to fill columns A, B and C using a loop with lua ? Thank you.

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 29 Sep '18

29 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 29 Sep '18

29 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 28 Sep '18

28 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/

Re: [NTG-context] Metafun: Finding intersection between characters
by Jeong Dal 28 Sep '18

28 Sep '18

Dear Hans, First, it is great to know a new method of drawing an outlined font! I have applied it to Korean fonts. As you know, every Korean character is composed with “consonant+vowel(+consonant)” type. If consonant and vowel are connected (for example, “호”), then it draws correctly, otherwise (for example, “하”) it draws only consonant. Is there a way to count all the paths in a character(even if it is not connected)? Thank you. Best regards, Dalyoung > > \starttext > > \startMPdefinitions > > % will be added to metafun: > > def filloutlinetext(expr o) = > draw image ( > save n, m ; numeric n, m ; n := m := 0 ; > for i within o : > n := n + 1 ; > endfor ; > for i within o : > m := m + 1 ; > if n = m : > eofill > else : > nofill > fi pathpart i ; > endfor ; > ) > enddef ; >

Rendering of Burmese Script
by Campanignis 28 Sep '18

28 Sep '18

Dear community, honestly, I do know almost nothing about ConTeXt. My sincere apologies. The answer https://tug.org/pipermail/lualatex-dev/2018-September/001681.html on my request https://tug.org/pipermail/lualatex-dev/2018-August/001680.html implies that this mailing list might be the right spot for my initial problem. Here is the initial problem: The following MWE renders correctly in XeLaTeX but not in LuaLaTeX and illustrates the problem. \documentclass{memoir} \usepackage{fontspec} \newfontfamily{\burmeseFamily}{NotoSerifMyanmar-Regular.ttf}[Scale=MatchLowercase] \begin{document} Test {\burmeseFamily{}တော်ကြီး} foo. \end{document} Thank you very much for taking your time. Yours with many thanks, Campanignis.
