Hi, When I want to draw the curve which corresponds to n=60 (blue curve), it doesn't seem possible: I don't understand.

no effect of \definefontfeature for adobevariablefontprototype

Hi, trying to work with variable fonts, I am stuck at the very beginning. I can't see any effect of weight parameter. Using adobevariablefontprototypebold and adobevariablefontprototypelight is working. \starttext \definefontfeature[whatever][axis={weight:150}]% \definedfont[name:adobevariablefontprototype*whatever]foo@bar \definefontfeature[whatever][axis={weight:350}]% \definedfont[name:adobevariablefontprototype*whatever]foo@bar \definefontfeature[whatever][axis={weight:550}]% \definedfont[name:adobevariablefontprototype*whatever]foo@bar \definefontfeature[whatever][axis={weight:750}]% \definedfont[name:adobevariablefontprototype*whatever]foo@bar \stoptext Can it be something from with my font file ? Thanks, Garulfo

Hi, list \startMPpage draw outlinetext.d("\mathematics{\sqrt{2}-1}")(withcolor black withpen currentpen) scaled 1; \stopMPpage fails (radicals are not drawn at all). As for context --version, mtx-context | ConTeXt Process Management 1.06 mtx-context | mtx-context | main context file: /usr/local/context/tex/texmf-context/tex/context/base/mkiv/context.mkiv mtx-context | current version: 2024.04.01 08:59 mtx-context | main context file: /usr/local/context/tex/texmf-context/tex/context/base/mkxl/context.mkxl mtx-context | current version: 2024.04.01 08:59 Maybe it's only me, but I tried with several fonts and the outcome is similar.

Is there a way to consolidate index reference numbers by book?
by Joel 11 May '24

11 May '24

\useregister[workbookA][03_workbook][learnedlong][WB~1:~] \useregister[workbookB][04_workbook][learnedlong][WB~2:~] \useregister[workbookC][05_workbook][learnedlong][WB~3:~] \useregister[workbookD][06_workbook][learnedlong][WB~4:~] \startchapter[title=Standards] \placeregister[learnedlong,workbookA,workbookB,workbookC,workbookD] \stopchapter I setup a custon index that lists items from four different workbooks. The problem is in the indexi, it displays entreis like this: WHST.1.1: 11, 231, WB 1: 124, WB 1: 133, WB 2: 325, WB 2: 345, etc. In other words, it says WB 1 in front of every page number from the first workbook. Is there any way to consolidate the page numbers by book, e.g. output instead like this: WHST.1.1: 11, 231, WB1: 124, 133, WB 2: 325, 345 In other words, it list all page numbers for Workbook 1 right after WB 1: instead of placing WB 1 in front of every single page from Workbook 1? --Joel

How to place text, but make it completely hidden from viewers?
by Joel 10 May '24

10 May '24

I have found a few situations is confusing/breaking ConTeXt: - Footnotes inside tables, figures, frames, margins (won't render the cited item). - Custom index items inside those items (displays "entry not flushed"). My workaround has been to define a size 0 font \tfz, then put it in a block like this: {\tfz% \starteffect[hidden]% \cite[author1912] \stopeffect% }% The problem this seems to create, is sometimes if placed between two passages, it interprets a need to create two paragraph breaks: \input knuth {\tfz% \starteffect[hidden]% \cite[author1912] \stopeffect% }% \input knuth It creates a paragraph break after the first knuth, then another after the hidden text, thereby creating a "double spaced" break between two paragraphs. Note the above code is used in many macros, so I don't have full control always where it appears, but its making the double-spaced break everywhere. Is there either (1) something can enter before this code that essentially has the effect of "backup to the previous paragraph" or (2) some other method of hiding text that makes it present on the page, but just not visible to the reader, that won't create a double spaced break, or take up any space what-so-ever? --Joel
