LMTX generates PDFs with non-working fonts on real printers
by Leah Neukirchen 13 Oct '22

13 Oct '22

Hi, I use LuaMetaTeX 2.10 20220918 + ConTeXt LMTX 2022.09.11. Here's a tiny test document, I disabled PDF compression but it also doesn't work with the default settings. \setupbackend[level=0,compresslevel=0] \starttext Just a line of text. \stoptext When I print this "directly" (i.e. sending the raw PDF to the printer) on a Ricoh MP3053 or on a Samsung CLP-680DW, I just get an empty page. The PDFs render fine on every PDF reader I could find. Conversion to PostScript with pstopdf (poppler-22.07.0) and then sending the PS renders the document correctly on the printer. PDFs generated directly from Context MKIV from TeXLive 2022 using LuaTeX 1.5 render fine on these printers. I've also printed PDFs from pdfTeX in the past fine. I attached the non-working 'foo.pdf.mkix' and the working 'foo.pdf.mkiv' file. I tried to disable font subsetting to debug this further, but I couldn't figure out how to do it. Any ideas what I should try to help debug this? cu, -- Leah Neukirchen <leah(a)vuxu.org> https://leahneukirchen.org/

\text{...} inside \sqrt is tiny
by Gavin 13 Oct '22

13 Oct '22

Hi List, When I use text inside a radical, the text is script-script size. $\text{Radius} = \sqrt{\text{Area}/\pi}$ It should be normal size. Any ideas for a fix? I stumbled on this issue when working with \units, but it is not specific to units. Thanks! Gavin

\quotation, protrusion and linebreaking
by Leah Neukirchen 13 Oct '22

13 Oct '22

Hello, I noticed the following problem: \showframe \startluacode fonts.protrusions.vectors.pure[0x201C] = { 1, 1 } \stopluacode \definefontfeature[default][default][protrusion=pure] \setupalign[hanging] \starttext This text is unquoted. “This text is quoted manually.” \quotation{This text is quoted by a macro.} This is a very long line followed by a nice linebreak, very supercalifragilisticexpialidocious. This is a very long line followed by an ugly linebreak, not \quotation{supercalifragilisticexpialidocious} \stoptext The macro-quoted text is not protruded. I fixed this locally with a macro \def\q#1{\protrusionboundary1\quotation{#1}} Should this be default? But the missing hyphenation I have to add myself with \-. Ideas? -- Leah Neukirchen <leah(a)vuxu.org> https://leahneukirchen.org/

regular online meet-up
by Henning Hraban Ramm 12 Oct '22

12 Oct '22

You’re invited to join on Wednesday, October 12th, 15:00 CEST (UTC+2) at https://lecture.senfcall.de/hen-rbr-rku-oke (same, but shorter: https://v34h.de/ctxmtg) ConTeXt users of all levels are welcome! Next meeting will be on November 9th. (Same blurb as every time:) [Howto] * No special software installation required; most modern browsers should work (WebRTC required). * Open the above URL, accept the privacy statement, * enter your name, * click "join" (or "start" if you’re the first), * click "with microphone", allow your browser to access it, check the audio. * Your microphone is muted if you join. Activate microphone and/or camera with the buttons at the bottom. * Minimize the default presentation with the "screen" button, bottom right. * If you’d like to share your screen or upload a file, you can make yourself the presenter: Click on your user name, change the setting, then you’ll see the "screen sharing" button beside the camera button; also there’s now "manage presentations" behind the "plus" button. Beware there is only one presenter at a time, so don’t kill someone else’s presentation. [Technical hints] * Sound is usually better if you use a headset (less noise for everyone). * Connection problems are mostly due to low bandwidth or high latency on your side, e.g. with mobile connections. * If audio/video doesn’t work for you, you can still use the text chat. * Screen sharing needs a lot of bandwidth. * BigBlueButton documentation applies: https://bigbluebutton.org/teachers/tutorials/ [Netiquette] * Please use a name that we recognize from here. Some feel uncomfortable with anonymous lurkers. * Mute your microphone while you’re not talking. * It’s nice to show your face at least when you join. * If there are connection problems, stop camera sharing. * The room is set to “everyone’s a moderator“, I trust you... See you, Hraban

Help test a LMTX bug fix: tweaks in PDF generation
by Leah Neukirchen 11 Oct '22

11 Oct '22

Hi, last week we had a long thread about non-printing PDF on this list and together with Hans I tracked down the issue and we found a fix. Since it changes some details of how PDFs are generated by LMTX, we'd like to test this change first on a wide range of software and printers. So please: Try to preview and then try to print the attached PDF; and report back if either preview or printout does not look like the attached reference PNG image (i.e. something is missing, the fonts look different, or have wrong relative size.) If you use other PDF tools in your workflow, please also check they continue to work as before (and just as well as with MKIV-generated PDFs). Thank you very much, -- Leah Neukirchen <leah(a)vuxu.org> https://leahneukirchen.org/

TOC colors and in-page anchors
by Sylvain Hubert 11 Oct '22

11 Oct '22

Dear list, \usemodule[ipsum] \setupinteraction[state=start] \starttext \completecontent \section{s1}\ipsum \section{s2}\ipsum \section{s3}\ipsum \section{s4}\ipsum \section{s5}\ipsum \section{s6}\ipsum \stoptext In the table of contents, s1 and s2 (at page 1) are rendered in red, while others in green. Moreover, when I click s4, it jumps to page 2 without locating the section precisely within the page. This is not the case when using the latex hyperref package. Does anyone know how to make the colors uniform and the links precise? Any help is appreciated. Sylvain

ConTeXt Standalone does not works on macOS Monterey with Apple M2 chip
by Tommaso Gordini 10 Oct '22

10 Oct '22

Hello list, I'm trying to install ConTeXt Standalone on my Mac (macOS 12.6 Monterey and Apple M2 chip) but at the end of the installation the ConTeXt-MkIV folder (where I install Standalone) on the disk weighs only 7MB (the tex tree is created, but its folders are empty). I've never had a problem installing it on my old computer (Intel processor). Do you know if it is a known problem? These are the commands I used (taken from the wiki): rsync -av rsync: //contextgarden.net/minimals/setup/first-setup.sh . sh ./first-setup.sh --modules = all --fonts = all --goodies = all --context = latest --engine = luatex Where am I wrong? LMTX installation, on the other hand, should be successful (the folder weighs 297.8 MB, as much as the Standalone one should weigh). Thanks in advance. Tommaso

How to get line numbering to match block quote position?
by Joel 10 Oct '22

10 Oct '22

I have some text that is a block quote, but also has line numbering: \setuplinenumbering[step=3] \starttext \startblockquote \startlinenumbering \input knuth \stoplinenumbering \stopblockquote \stoptext The line numbering is appearing in the left margin as if the text were not a block quote. How can I tell it to move the numbering closer to the text, since the text is not up against the margin, being block quote text? --Joel

startTEXpage on A4
by Leah Neukirchen 10 Oct '22

10 Oct '22

Hi, is there a way to have something like \setuppapersize[A5][A4] but have the "inner paper size" be a computed fit like in \startTEXpage? Or, alternatively, is there is a way to print crop marks around an environment like \startTEXpage? Thanks, -- Leah Neukirchen <leah(a)vuxu.org> https://leahneukirchen.org/

\setuparranging values for perfect bound A5 on A3?
by Bruce Horrocks 09 Oct '22

09 Oct '22

I have a book to be perfect bound[1] and I'm trying to work out what imposition to use. The printer would like 4 A5 pages laid out on A3 e.g. +---+---+ | | | | a | b | | | | +---+---+ | | | | c | d | | | | +---+---+ so that he can cut the paper and simply stack a, b, c, & d on top of each other and then put them in the binding machine[2]. If the book is 40 pages long, say, then stack 'a' has page 1 on the top, page 2 on the reverse, then the next sheet has page 3 and 4, and so on down to the last sheet which has page 9 on the front and page 10 on the back. Stack 'b' would have page 11 on the front, 12 on the back and so on, so that each stack has a quarter of the book. Is this something LMTX can do and if so what combination of \setuplayout and \setuppaper do I need to use? If they can be printed in reverse order then great but I assume the printer can do that fairly easily. If not, is there a recommended external program that can do it? I've tried \setuplayout[4*2] and XY with 2x2 but neither output is what I need. Thanks in advance. [1] glued spine (if that term isn't used outside the UK) [2] I'm sure it's actually harder than that. :-) — Bruce Horrocks Hampshire, UK
