Problem with float and new layout on same page
by peter.hopcroft＠icloud.com 25 Dec '22

25 Dec '22

My MWE below produces this pdf. My problem is that on page 2, the body text flows beyond its frame and into the footer distance. Regards, Peter MWE: \setuppapersize[A4][A3,landscape] \setuparranging[2SIDE] \showframe \definelayout[mypage][footerdistance=100mm, ] \definelayout[odd][reset] % ?? \definelayout[even][reset] \starttext \dorecurse{3}{\input{knuth} } % change to \dorecurse{2} - it works properly \definelayout[2][mypage] \dorecurse{2}{\input{knuth} } \placefigure [leftmargin] {} {\externalfigure[greybox][width=\leftmarginwidth]} \dorecurse{5}{\input{knuth} } \stoptext ------------------------------------------------------------

Help for using fonts Nupuram
by Alain Delmotte 23 Dec '22

23 Dec '22

Hi! I am trying to run the example Hans published on the 1st of December with a new upload. It is about using the variable font Nupuram. I downloaded the font in a big .zip file. It contains: two explaining files and folder with sub-folder "Nupuram", which in turn contains 6 subsub-filders: - otf with 32 otf font files - otf-variable with 1 file "Nupuram-VF.otf" - ttf with 32 ttf font files - ttf-variable with 1 file "Nupuram-VF.ttf" - ufo with 32 subfolders xxx.ufo - webfonts with 33 xxx.woff2 files After looking to contextgarden,I tried to put the "Nupuram" sub-folder or only the folders with .otf in different places of my context-lmtx folder, and using "mtxrun --script font --reload". But the example of Hans didn't work. Then I install the .ttf font files in Windows\fonts; it works, but 1) trying to install the Nupuram-VF.ttf, I have the message that Nupuram-Regular is already installed; and 2) I get the font in the example, but no changes of width or colour. So, now I deleted all the Nupuram everywhere. How could I have it fully working under context-lmtx? I have different places for fonts in my context-lmtx: - tex\texmf\fonts mainly empty except \data - texmf-context\fonts populated - texmf-fonts empty - texmf-modules\fonts populated Thanks for you help. Merry Christmas and Happy New Year, Regards -- Alain

xtables regression with LMTX 2022-12-21
by Rik Kabel 22 Dec '22

22 Dec '22

With the latest (2022-12-21) LMTX I see a regression in xtables. The following code: \starttext \startxtable \startxrow \startxcell This is a line of text. \stopxcell \startxcell \contextversion \stopxcell \stopxrow \stopxtable \stoptext produces this with 2022-12-09: and this with 2022-12-21: The problem appears to be LMTX-specific. (I did not save 2022-12-15 for testing, but did not see the problem with that version.) -- Rik

LMTX: request for \tracinglostchars=3
by Leah Neukirchen 22 Dec '22

22 Dec '22

Hi, since TeX Live 2021 (TeX 3.141592653), there is > - if \tracinglostchars >= 3, make missing characters an error (not just > a log message), and always report the character code in hex. LaTeX also enables this by default these days. LMTX only seems to support =0 (ignore) and =1 (report). Making these a fatal error (with exit status != 0) would be useful for automated typesetting, as missing characters easily can get lost in the logs, and then symbols are missing unnoticed in the output. (However, \tracinglostchars=3 also doesn't seem to work with LuaTeX+MKIV, probably because there is code to fallback to other fonts?) cu, -- Leah Neukirchen <leah(a)vuxu.org> https://leahneukirchen.org/

Unconnected \mathboxanchored produces unexpected results
by Gavin 22 Dec '22

22 Dec '22

Hi Hans, MIkael and list, I got an unexpected result when I asked for a \mathboxanchored, but then did not use it with a connector. I expected the \mathboxanchored contents to be typeset as usual, without a connector. Instead I got “ ::: c3” added into the formula (“c3” was the anchor’s tag). MWE and unexpected output below. Thanks, Gavin \starttext \startboxanchoring[+] \connectboxanchors[top] [top] [distance=1ex,arrow=no] {c1}{c2} %\connectboxanchors[bottom] [bottom] [distance=1ex,arrow=no] {c2}{c3} % <-- I decided not to use this connector, producing unexpected results. \startformula \mathboxanchored[nucleus]{c1}{e}^{\dot\alpha} \mathboxanchored[nucleus]{c2}{e}_{\mu} \mathboxanchored[nucleus]{c3}{e}^{\beta} = \frac{1}{\sqrt{2}} \bar\sigma^{\dot\alpha\beta}_{\mu} \stopformula \stopboxanchoring \stoptext

Accent wrecking \mathboxanchored
by Gavin 22 Dec '22

22 Dec '22

Hi Hans, Mikael and list, I’ve been testing the connectors, which work great with the latest upload. One problem I found: an accent in the \mathboxanchored causes a "Missing number, treated as zero” error and no output. MWE below. Thanks for all of the improvements. I’m making all kinds of connections! Gavin \starttext \startboxanchoring[+] \connectboxanchors[top] [top] [distance=1ex,arrow=no] {c1}{c2} \connectboxanchors[bottom] [bottom] [distance=1ex,arrow=no] {c2}{c3} \startformula \mathboxanchored[nucleus]{c1}{e}^{\dot\alpha} % \mathboxanchored[nucleus]{c2}{e}_{\mu} % <-- This works, without accent % \mathboxanchored[nucleus]{c2}{\bar{e}}_{\mu} % <-- This does not work, with accent \bar{\mathboxanchored[nucleus]{c2}{e}}_{\mu} % <-- This works, but connector punches through accent \mathboxanchored[nucleus]{c3}{e}^{\beta} = \frac{1}{\sqrt{2}} \bar\sigma^{\dot\alpha\beta}_{\mu} \stopformula \stopboxanchoring \stoptext

move glyph vertically
by Pablo Rodriguez 22 Dec '22

22 Dec '22

Dear list, I have the following sample: \startluacode fonts.handlers.otf.addfeature { name = "gpos_test", type = "single", data = { [ '¿' ] = 1000, [ '¡' ] = 1000, } } \stopluacode \definefontfeature[ktest][gpost_tes=yes] \starttext \startTEXpage[offset=1em] \feature[+][gpos_test] ¿? ¡! \stopTEXpage \stoptext This tries to move vertically the opening question and exclamation marks, so they are at the same height that its closing counterparts. I thought there may be a GPOS feature that could achieve this, but I must admit I have no idea about how to achive it. In my document, this should only work with the slanted feature. Could anyone tell me how could I move vertically single glyphs? Many thanks for your help, Pablo

Unwanted space with \startframedtext
by Max Chernoff 22 Dec '22

22 Dec '22

Hi Hans, There's an uncommented linebreak in the definition of \pack_framed_text_start that's introducing an unwanted space just before \startframedtext. Minimal example: \showmakeup[space] \starttext \hbox{.\startframedtext.\stopframedtext} \stoptext Patch: --- texmf-context/tex/context/base/mkxl/pack-rul.old 2022-12-21 19:12:14.790830416 -0700 +++ texmf-context/tex/context/base/mkxl/pack-rul.mkxl 2022-12-21 19:12:26.193652551 -0700 @@ -2693,7 +2693,7 @@ \tolerant\protected\def\pack_framed_text_start[#1]#*[#2]#*[#3]% or #1#*[#2]#*[#3]% and pass {#1} {\bgroup - \edef\currentframedtext{#1} + \edef\currentframedtext{#1}% \doifelseassignment{#2} {\pack_framed_text_start_indeed\empty{#2}} {\pack_framed_text_start_indeed{#2}{#3}}} (originally reported at https://tex.stackexchange.com/q/669296/270600) Thanks, -- Max

Use section custom value in a header text.
by Pawel Urbanski 22 Dec '22

22 Dec '22

Dear Friends, I spent some time searching and coding simple documents, but failed and therefore I'm asking for help... A section such as chapter cn have custom keys with values. One uses the: \structureuservariable command to access such values. How can I use such a value to create a custom header in a format: Prefix: \structureuservariable{foo} I am asking for the only thing that worked when I tried was calling the: \setupheadertexts command inside a chapter environment block with some prefix. Unfortunately the value from the custom field was not expanded. It was correctly inserted in a regular paragraph. For example: \startchapter [title={A sample title}][custom_something={random_value}] ... \stopchapter How can I put the value of: custom_something in the header with some prefix? All the best and thanks, Pawel
