Convertnumber with \ref[number] fails in MkIV, works in LMTX
by Rik Kabel 06 Dec '22

06 Dec '22

Hello list, The following fails with ConTeXt ver: 2021.10.24 21:45 MKIV but works with the companion LMTX. The error message is:tex error > tex error on line 6 in file G:/TestConTeXt/convert.tex: ! Incompatible glue units , pointing to the second \convertnumber line. \definelabel[XX]%[text=,before=,after=,alternative=inright] \startTEXpage[offset=2em] abc\XX[xx]\par \ref[number][xx] · \convertnumber{r}{1} · \convertnumber{R}{\ref[number][xx]} \stopTEXpage In this case I am trying to display with roman numerals the number generated in the label created through \definelabel. Suggestions welcomed. -- Rik

TeXGyre Heros on Firefox
by juh 19 Oct '22

19 Oct '22

Dear all, there were some discussions on pdf viewers on the list and I know that things are not always fine. I now have a problems with the Firefox pdf viewer and TeX Gyre Heros. The font looks uneven in FF, no problems elsewhere. When I scroll into the pdf to set the display to 150% or more the font shows up just fine. So it seems to be a display problems with firefox. I tried several pdf versions no change. My configuration: \definefontfamily[mainfont][serif][texgyreheros] \definefontfamily[mainfont][sans] [textgyreheros] \definefontfamily[mainfont][mono] [texgyrecursor][features=none] \definefontfamily[mainfont][math] [texgyrepagellamath] \definefallbackfamily [mainfont] [rm] [Latin Modern Math] [scale=0.925, range=0x22C0] \definefontfeature[smallcaps][script=latn, protrusion=quality, expansion=quality, smcp=yes, onum=yes, pnum=yes] \setupalign[hz,hanging] \setupitaliccorrection[global, always] Is there anything I can do? And the is another issue: To my big surprise ArialBold MT is included into the file. I am using the current lmtx. If you want to see the effect, download the pdf. https://www.hostsharing.net/publikationen/vereinshandbuch/ Just click on "Anonym herunterladen" no need to register.

Count (and limit) glyphs per line?
by Benjamin Buchmuller 26 Jul '22

26 Jul '22

Dear list, I've been confronted with the following 'intriguing' formatting requirement for a document: " • Type density: Must be no more than 15 characters per linear inch (including characters and spaces). • Line spacing: Must be no more than six lines per vertical inch. " While the line spacing resolves in ConTeXt to \setupinterlinespace[line=\dimexpr(1in / 6)] I was wondering if one can limit "type density" as the number of glyphs per inch in TeX too? I thought, it is more convenient to rephrase this request (for a 7 in textwidth) to limit the number of glyphs per line to 112. (Font must be sans or serif, of course ...) I've tried \setuplayout[width=112\averagecharwidth] which, however, results in ~120–130 characters and spaces per line. Pragmatically, I'm narrowing the text width to empirically match the requirement, but I'm nevertheless curious if there is a Lua/TeX solution to this "problem"? Thank you! Benjamin

> From: juh+ntg-context(a)mailbox.org > My main problem is that I never used Windows in my life and have no idea > how to help people with installing lmtx on this platform. > > juh I'm a beginner in context (and not a programmer by profession) and installing lmtx on windows was very easy for me. the steps are on the wiki https://wiki.contextgarden.net/Installation and it is as easy as it is written there. I've been using context thanks to these installation steps on win 7 and win 10. I'm not sure what the targetgroup at the conference is, but if the people there ever used a commandline, they should be good to go. once you install, you open the commandline using Win+R and then type "cmd". Once in the cmd, you only need to know the command "cd" (change directory) to navigate to the folder where the .tex source is, so e.g. "cd c:\users\x\documents\" and then run "context test.tex". That is the manual way. I use sublimetext as text editor and made a new build for it, that when I press Ctrl+B saves all changes in the open file/folder and runs context on the open file and previews the pdf in mupdf that is zoomed to be 1:1 paper:print on my dpi. It's a bit like TeXworks, just press button and see the pdf, because mupdf automatically overwrites the open pdf without asking. It's 4 hours by train for me to Bonn and I'm not sure whether I'm a good candidate to teach people context due to my low skill, but I can surely teach you how to install lmtx on windows if you like (we could call or sth). Best, Andrej

Tagging corrupts URLs in bibliographies
by Max Chernoff 30 Jun '22

Enabling PDF tagging corrupts the URLs displayed in bibliographies. MWE: \setuptagging[state=start] \usebtxdataset[mkiv-publications.bib] \usebtxdefinitions[apa] % \usebtxdefinitions[chicago] \starttext \nocite[article, advancedonline] \placelistofpublications \stoptext I think that APA and Chicago are the only styles that display URLs in the bibliography, but there may be others that I'm missing. There's a patch at the end that seems to fix things for me, although there's likely a better solution. -- Max --- texmf-context/tex/context/base/mkiv/publ-ini.old 2022-06-30 14:54:35.422262400 -0600 +++ texmf-context/tex/context/base/mkiv/publ-ini.mkiv 2022-06-30 15:06:28.975132000 -0600 @@ -399,6 +399,7 @@ % This fails when we check field values: \let\btxrawfield\btxfield +\let\btxrawflush\btxflush \def\btxfield #1{\dostarttagged\t!pubfld{#1}\clf_btxfield {\currentbtxdataset}{\currentbtxtag}{#1}\dostoptagged} \def\btxdetail #1{\dostarttagged\t!pubfld{#1}\clf_btxdetail{\currentbtxdataset}{\currentbtxtag}{#1}\dostoptagged} --- texmf-context/tex/context/base/mkxl/publ-ini.old 2022-06-30 15:05:36.018821900 -0600 +++ texmf-context/tex/context/base/mkxl/publ-ini.mkxl 2022-06-30 15:06:22.220074900 -0600 @@ -399,6 +399,7 @@ \aliased\let\btxsetup\fastsetup \permanent\def\btxrawfield #1{\clf_btxfield {\currentbtxdataset}{\currentbtxtag}{#1}} +\permanent\def\btxrawflush #1{\clf_btxflush {\currentbtxdataset}{\currentbtxtag}{#1}} \permanent\def\btxfield #1{\dostarttagged\t!pubfld{#1}\clf_btxfield {\currentbtxdataset}{\currentbtxtag}{#1}\dostoptagged} \permanent\def\btxdetail #1{\dostarttagged\t!pubfld{#1}\clf_btxdetail{\currentbtxdataset}{\currentbtxtag}{#1}\dostoptagged} --- texmf-context/tex/context/base/mkiv/publ-imp-apa.old 2022-06-30 14:56:18.210565000 -0600 +++ texmf-context/tex/context/base/mkiv/publ-imp-apa.mkvi 2022-06-30 14:56:40.611212000 -0600 @@ -1263,12 +1263,12 @@ \setbreakpoints[doi] \ifconditional\btxinteractive \goto { - \hyphenatedurl{\btxflush{url}} + \hyphenatedurl{\btxrawflush{url}} } [ - url(\btxflush{url}) + url(\btxrawflush{url}) ] \else - \hyphenatedurl{\btxflush{url}} + \hyphenatedurl{\btxrawflush{url}} \fi \endgroup \stoptexdefinition @@ -1280,12 +1280,12 @@ \setbreakpoints[doi] \ifconditional\btxinteractive \goto { - \hyphenatedurl{doi:\btxflush{doi}} + \hyphenatedurl{doi:\btxrawflush{doi}} } [ - url(http://dx.doi.org/\btxflush{doi}) + url(http://dx.doi.org/\btxrawflush{doi}) ] \else - \hyphenatedurl{doi:\btxflush{doi}} + \hyphenatedurl{doi:\btxrawflush{doi}} \fi \endgroup \stoptexdefinition --- texmf-context/tex/context/base/mkiv/publ-imp-chicago.old 2022-06-30 14:59:53.310100000 -0600 +++ texmf-context/tex/context/base/mkiv/publ-imp-chicago.mkvi 2022-06-30 15:00:39.497438200 -0600 @@ -1258,12 +1258,12 @@ \setbreakpoints[doi] \ifconditional\btxinteractive \goto { - \hyphenatedurl{\btxflush{url}} + \hyphenatedurl{\btxrawflush{url}} } [ - url(\btxflush{url}) + url(\btxrawflush{url}) ] \else - \hyphenatedurl{\btxflush{url}} + \hyphenatedurl{\btxrawflush{url}} \fi \endgroup \stoptexdefinition @@ -1275,12 +1275,12 @@ \setbreakpoints[doi] \ifconditional\btxinteractive \goto { - \hyphenatedurl{doi:\btxflush{doi}} + \hyphenatedurl{doi:\btxrawflush{doi}} } [ - url(http://dx.doi.org/\btxflush{doi}) + url(http://dx.doi.org/\btxrawflush{doi}) ] \else - \hyphenatedurl{doi:\btxflush{doi}} + \hyphenatedurl{doi:\btxrawflush{doi}} \fi \endgroup \stoptexdefinition

Odd behaviour with Plex typescript
by Max Chernoff 30 Jun '22

30 Jun '22

If you load the Plex typescript, a spurious space is added on the first switch to another font, messing up any alignment. This doesn't happen with any other fonts; only with Plex. MWE: \setuphead[section][style={\switchtobodyfont[modern]}] \setupbodyfont[plex] \starttext \section{A} A \stoptext I was able to fix this by removing the space immediately before the "%" on line 136 of "type-imp-plex.mkiv", changing it from this (original): \definefontfeature[plexwideneddefault][default][extend=\luaexpr{1/0.85}] % An odd floating point number to correct monospace. to this (fixed): \definefontfeature[plexwideneddefault][default][extend=\luaexpr{1/0.85}]% An odd floating point number to correct monospace. I'm pretty sure that TeX is ignoring spaces at this point, so I have no idea why this issue exists or why the fix works. -- Max

\setextrafontkerns can cause an infinite loop
by Max Chernoff 30 Jun '22

30 Jun '22

Sometimes using \setextrafontkerns can cause an infinite loop. Example 1: \setextrafontkerns[max] \starttext l\it l \stoptext Example 2: \setupbodyfont[libertinus] \setextrafontkerns[max] \starttext x\ss x \stoptext Both of these examples cause ConTeXt to get stuck until it runs out of memory. This happens in both MkIV and MkXL. This patch seems to fix the issue (although it may break other things...): --- texmf-context/tex/context/base/mkiv/typo-fkr.old 2022-06-30 03:05:17.702804200 -0600 +++ texmf-context/tex/context/base/mkiv/typo-fkr.lua 2022-06-30 03:05:22.286858200 -0600 @@ -57,6 +57,7 @@ end if kern ~= 0 then head, current = insertbefore(head,current,new_kern(kern)) + current = getnext(current) end lastdata = data else @@ -69,6 +70,7 @@ local kern = getkernpair(lastdata,lastchar,char) if kern ~= 0 then head, current = insertbefore(head,current,new_kern(kern)) + current = getnext(current) end end lastchar = char -- Max

Auto width and height on table cells
by Angel M Alganza 30 Jun '22

30 Jun '22

Hello, I want some tables to occupy 100% of \textwidth and \textheight and for all columns to be the same width except one or two that I want to specify and for all rows to be the same height except for one or two, that I want to specify as well.. For the moment, I'm doing it "manually", calculating column width as (\textwidth - width of fixed columns) / # rest of columns and row height as (\textheight - height of fixed rows) / # rest of rows I'm getting the result that I want, but it's a bit tedious. Is it possible to have ConTeXt do all those calculations for me? I haven't been able to figure it out from the manuals and the wiki. Thank you in advance. Regards, Ángel
