Problems with itemize with several columns
by Xavier B. 25 Feb '22

25 Feb '22

Hi, I try to solve this, but I could not. Can you please help me. I make a math problem sheet. In "Exercici 1.2", I put a itemize with three columns, but the 'c' exercise jumps to second column. I want that a, b, c remains in the first column, d, e, f in the second and g, h, i in the third. I tried \column command but it's worse. I attached the source and generated pdf. My version of context is: context --version mtx-context | ConTeXt Process Management 1.04 mtx-context | mtx-context | main context file: /usr/share/texmf-dist/tex/context/base/mkiv/context.mkiv mtx-context | current version: 2021.03.05 19:11 mtx-context | main context file: /usr/share/texmf-dist/tex/context/base/mkxl/context.mkxl mtx-context | current version: 2021.03.05 19:11 Thanks in advance, Xavier PS: Please CCme

Cyrillic alternate form in Neacademia
by Stefan Nedeljkovic 22 Feb '22

22 Feb '22

Dear list, I'm using the typeface Neacademia Text, and I'm trying to configure it to the specifics of the Serbian language. I want to replace the usual form of the lowercase cyrillic letter BE with the traditional Serbian form. I opened the font file in Font Forge and looked up the glyph info. Here is what I tried and what failed: \startluacode fonts.handlers.otf.addfeature { name = "besub", type = "substitution", data = { ["uni0431"] = "uni0431.SRB.alt" } } \stopluacode \definefontfeature[default] [mode=node,kern=yes, liga=yes,dlig=yes, calt=yes,ss03=yes, case=yes,ccmp=yes, locl=yes,script=cyrl,language=srb, besub=yes] No luck using hex codes either: \startluacode fonts.handlers.otf.addfeature { name = "besub", type = "substitution", data = { [0x1ab] = 0x3f8 } } \stopluacode"uni0431" Interestingly the single substitutions from page 175 of the fonts manual seem to work just fine. Any help is appreciated. Sincerely, Stefan

Bibliography
by Willi Egger 22 Feb '22

22 Feb '22

Hi all, I have a rather old project which involves a bibbliography of about 60 entries. — Now I tried to use the publications environment after reading the manual. — I must say environment this is impressive! However I struggle with getting it working. 1. When using my dataset, which is encoded as a ‘bbl’ type file I get a list of publications but the entries are uncomplete. enclosed files: publist-test.tex, test-literaturliste.bbl, publist-test.pdf 2. When I use a buffer for testing, I do not get \cite reference nor a publication list: publist-buffer-test,tex Can someone advise? Kind regards Willi

Disable reuse of figures
by Aditya Mahajan 21 Feb '22

21 Feb '22

Hi, This is related to a bug report for the filter module: https://github.com/adityam/filter/issues/60 Normally, when the same figure is included twice, context only includes the figure once and refers to the included figure the second time. The option `object=no` to externalfigure is supposed to prevent that, but it doesn't work. For example, consider the following example the bug-report uses graphviz as the external program, but I have changed that to context to keep things self contained) \usemodule[filter] \defineexternalfilter [graphviz] [ filter=context --purge, output=\externalfilterbasefile.pdf, readcommand=\ReadPDF, ] \def\ReadPDF#1% {\externalfigure[#1][object=no]} \starttext Circle: \startgraphviz \startMPpage draw fullcircle scaled 1cm; \stopMPpage \stopgraphviz Square: \startgraphviz \startMPpage draw fullsquare scaled 1cm; \stopMPpage \stopgraphviz \stoptext Behind the scenes, the first \startgraphviz ... \stopgraphviz environment writes the content to an external file (\jobname-temp-graphviz.tmp), runs `context --purge \jobname-temp-graphviz.tmp`, which creates `\jobname-temp-graphviz.pdf`. The `\ReadPDF` macro then includees the file (with object=no). At the next \startgraphviz .. \stopgraphviz, the same process is repeated. The `\jobname-temp-graphviz.pdf` file is overwritten and the new file should have been included. But it is not. The output contains the first image twice. I thought that object=no should have prevented the reuse. In fact, if I compile the file with luatex, I get an error message: ! error: (pdf inclusion): file has changed '12-two-outputs-temp-graphviz.pdf' mtx-context | fatal error: return code: 256 Any idea why object=no is not working? Thanks, Aditya

footnote width in specific paragraph instance
by jbf 19 Feb '22

19 Feb '22

I need to typeset a document that contains many poetry/verse examples, and am using \defineparagraphs[mypar][n=2] for the purpose. In one specific case a footnote is required. All good except that the footnote is the width of one of those two 'columns', not the usual textarea width. Here is the current setup (the 'poem' environment is previously defined and not relevant here for my problem): \startmypar \startpoem red desert dust invades every crevice – vast deserts that we inhabit inhabit us\footnote{The ‘reddesert dust...’ is adapted from Matthew diNevop. 103.} \stoppoem \nextmypar \startpoem {\emI will lead you into the wilderness, speak fondly to you of my everlasting love my unfailing kindness} \stoppoem \stopmypar The resulting footnote: 1. The ‘red desert dust...’ verse overleaf is adapted from Matthew di Nevo p. 103 Is there a way I can get the footnote not to break after 'overleaf' and be normal textarea width instead? I did try \setupfootnotes[width=broad] but that did not help. Julian

Suggestions for more math classes?
by Mikael Sundqvist 16 Feb '22

16 Feb '22

Dear all, While discussing spacing in math with Hans, we have come to the conclusion that to have better control and cleaner code there might be a good idea to have more math classes than the usual ones in TeX (ord, op, bin, rel, open, close, punct, inner (and some that we need not to think about)). So far, Hans has implemented frac and rad for fractions and radicals. The fractions has been a funny construction, being put inside empty delimiters, and so surrounded by the \nulldelimiterspace (which has been set to 1.2pt, independent of font size). Now we have better control of the spacing around fractions. Hans has opened up (even in the code) for the addition of more classes. The overall aim is to have a more coherent and logical way of typing math, without manual adding of (arbitrary) spaces every now and then. For example, we have always written \int f(x)\, dx to have a thin space between the closing parenthesis and the d in integrals. There will (most likely) be a differential class. Since the d might occur in other places in a formula with integrals, one cannot just simply give the letter d the differential class, and we are currently discussing the correct way for the user to type it. If you have suggestions, please let us hear! Some further suggestions by Hans are (see below for two more) 13 imaginary 14 differential 15 exponential 16 function Q1: Do you have any further suggestions on new classes (or comments on these)? It might be good to think about situations where you have felt that you need to insert manual spaces such as \, or \! to obtain a better result. I give one contribution: I asked a colleague to look in his TeX files for manual spaces, and he came up with several \, (usually before the d in integrals) but also with \!. This \! occurred mostly in fencing situations to have the exponent come a bit closer to the closing parenthesis. \left( \frac{x}{2} \right)^{\! k+2n} I have seen this in many places before, so no originality is claimed. Two more classes that we thought of are under and over. Say that we have a\overbar{bc}d. Should the spacing between a and the \overbar{bc} and the spacing between \overbar{bc} and d always be tight? If so, these might just be ord, and no new class needed (although one could argue for adding the classes now, set them up as ord, and thus being able to configure them according to taste/need). Q2: Do you have any real examples of constructions with \overbar, \underbar, \overbrace, ... or if you have any strong opinion, please raise your voice! /Mikael

\hyphenatedurl in non-hyphenation context
by denis.maier＠unibe.ch 15 Feb '22

15 Feb '22

Hi, I have defined chapter headings set to nothyphenated. Yet, sometimes occur DOIs in these chapter headings, and I would obviously want those to be broken across lines. %%%%%%%%%%%%%%%%%%%%%%%%% \setuppapersize[A6] \setuphead[chapter][align={right,nothyphenated}] \starttext \chapter[title={asdf asdf \goto{\hyphenatedurl{https://doi.org/10.12345/12345.12345}}[url(https://doi.org/10.12345/12345.12345)]}] bla \stoptext %%%%%%%%%%%%%%%%%%%%%%%%% For now, I'm changing the definition to \setuphead[chapter][align={right,lesshyphenation}], but is there a way to disable hyphenation, but still break urls across lines? Best, Denis

14 Feb '22

Hi, Is there something like shapepar (LaTeX-package) for ConTeXt? I would like to do the same as "\heartpar{text}" (see http://mirrors.ctan.org/macros/latex/contrib/shapepar/shapepar.pdf page 9) with ConTeXt. TIA for any hints, -- Peter

Harfbuzz plugin and colors

Hi, list! I've tested the Harfbuzz plugin in ConTeXt and it works nicely for most cases. However, color doesn't seem to work. Is this intended? I know this plugin won't be supported, but I'll be fine with pointers to solve this issue.
