XML processing, unwanted indentation/alignment
by Michael Guravage 16 Feb '24

16 Feb '24

Greetings, I'm typesetting an address book whose addresses are in XML. A typical entry has this structure: <family surname=""> <address street="" housenumber="" postcode="1" city="" telephone="" /> <members> <member first_name="" initials="" maiden_name="" birthday="" email="" mobile="" /> <member first_name="" initials="" birthday="" email="" mobile="" /> <member first_name="" initials="" birthday="" /> </members> </family> initials and birthday are required, first_name can be left blank and email, mobile and maiden_name are optional. I've written a macro (name) to compose the name, i.e. initials, first_name (maiden_name), and another macro (nameemaillink) to make the name a link associated with an email address. % Derive an individual's name \def\name#1% {\ifxmlattempty{#1}{first_name} {\xmlatt{#1}{initials}} \else {\xmlatt{#1}{initials}, \xmlatt{#1}{first_name}} \fi \ifxmlattempty{#1}{maiden_name} {} \else { \tfxx(\xmlatt{#1}{maiden_name})} \fi} % Create a mailto:link that associates a individual's name with their email address. \def\nameemaillink#1% {\ifxmlattempty{#1}{email} {\name{#1}} \else {\goto{\name{#1}} [url(mailto:\xmlatt{#1}{email})]} \fi} I thought I was done when I noticed that a composed name with an empty first name, with or without an email address, is slightly indented. In the mwe Moe and Curly, without first names, are indented; while Shemp and Michael aren't. That the undesired indentation/alignment is dependent on the presence of a first name is baffling. After this long description, if someone would look at the code and tell me where I've gone wrong I would be very grateful. The interesting bits begin on lines 8 and 12 in xml.tex. -- With kind regards, Michael

>> This is wrong, the counter commands are official and the number variants are kept for backwards compatibility with old styles. I do recall reading on the ConTeXt wiki that \definenumber is maintained for backwards compatibility reasons. However, why then does ConTeXt fail to compile with \getcounter, if that's how it's supposed to work? I was confused, don't get me wrong, but what I wrote was my own conclusion on the matter. Clearly, we have a bug that needs to be reported. I wish my email hadn't included such misinformation. But now, this is a bug that needs to be resolved. I'm running ConTeXt version 2024.01.24, and the given attachment fails to compile, even with MkIV. I don't want to pester those subscribed to this mailing list with bug reports, so I thought it would be more sensible to post such reports on the context developers mailing list. I ask for confirmation that I can post there instead of here. Thanks.

Dear list, the new lpdf-wid.lmt contains in lines 302 and 377: local relation = specification.relation or "Unspecified" AFRelationship = pdfconstant(relation), The following sample compiled with current latest: \setupinteraction[state=start] \starttext attachment\attachment[method=hidden, relation=Data, file=xml-mkiv.pdf] \stoptext Gives the following object: 2 0 obj << /AFRelationship /Unspecified /EF << /F 1 0 R >> /F (xml-mkiv.pdf) /Type /Filespec /UF <FEFF0078006D006C002D006D006B00690076002E007000640066> >> endobj Sorry, but which is the right way to specify the /AFRelationship for embedded documents? Many thanks for your help, Pablo

Installation of linux-32bits
by Alain Delmotte 15 Feb '24

15 Feb '24

Hi! I tried to install the linux 32 bits kindly provided by Hans. It went all right up to: mtxrun -generate First I had to change my PATH putting the path to lmtx before TeXlive, because it was always the files from TeXlive which were used. Then I got: ---------------------------- alain@alain:~/context/tex/texmf-linux/bin$ mtxrun --generate resolvers | resolving | variable 'SELFAUTOLOC' set to '/home/alain/context/bin' resolvers | resolving | variable 'SELFAUTODIR' set to '/home/alain/context' resolvers | resolving | variable 'SELFAUTOPARENT' set to '/home/alain' resolvers | resolving | variable 'TEXMFCNF' set to '' resolvers | resolving | variable 'TEXMF' set to '' resolvers | resolving | variable 'TEXOS' set to 'context' [...] resolvers | resolving | resolvers | resolving | warning: no lua configuration files found resolvers | resolving | no texmf paths are defined (using TEXMF) resolvers | resolving | mtxrun | mtxrun | elapsed lua time: 0.113 seconds ----------------------------- so the binaries were not created. What did I wrong? How to solve the problem? Thanks, Alain

Hi ConTeXt users, Wondering whether there is a possibility to modify the word *see* into the Dutch word *zie* in the use of the \seeindex command? Regards, Gerard

upload
by Hans Hagen 15 Feb '24

15 Feb '24

Hi, as we're around texlive code freeze time we're also in upload mode - i uploaded a new lmtx - i also added linux and windows 32 bin (as it seems to have users) - we're now using lua 5.5 which has one restriction (was already announced a while ago): for i=1,10 in t do .... i = 2 * i .... end should now be: for i=1,10 in t do .... local i = 2 * i .... end as one cannot change the (local constant) i which actually is not that different from what metapost does. The good news is that voilating this is reported when a lua file is loaded so one can't get it unexspectedly.

An announcement of my new book.
by SirColeman 14 Feb '24

14 Feb '24

Greetings all. I have a passion for typesetting. I found that currently the best typesetting systems are those that are based on TeX. Of them, there are LaTeX, and ConTeXt. LaTeX is very well documented and popular; ConTeXt, on the other hand, is apparently very powerful and capable, but is not as well documented. There are things that are spectacularly well documented, others that only show hints, and leave it up to the user to figure things out on their own, and others still that won't even compile on a more recent version of ConTeXt (apparently the proper way to access a counter's value in ConTeXt is to use \getnumber or \convertednumber, and not \getcounter. That's just an example). I thus thought, as an exercise in typesetting, in writing, and also to help the ConTeXt documentation, to write a new book, a large book, that teaches the details of how ConTeXt on a lower level works, allowing one to understand how to utilize low level typesetting features for anything more sophisticated than a simple book or article. By lower level, I mean how things like heads, items, references, alignment, tables, etc., work. Also, I would like a book that teaches things like how to program it using lua, how to understand and utilize the underlying engine itself (the low level LuaMetaTeX), how to even use DocBook with ConTeXt, etc. (I do realize that there already are manuals for lua in ConTeXt and on LuaMetaTeX, etc., and manuals on various different parts of ConTeXt, and I'll certainly be learning from them whenever their particular topic comes, but I reserve the opportunity to rewrite parts of these manuals for this book, as is necessary for the book's purpose, perhaps referencing these manuals for further details.) In particular, I want to go a step beyond the book "A not so short introduction to ConTeXt Mark IV", and teach the particularly advanced features, where there is sparse information. Particularly, it's meant to serve as one complete reference, instead of having to hunt for different manuals, which explain things differently, and with the consequence that it's hard to find a particular piece of information because its scattered around so many different places. This book should serve as the one and only final documentation that you would need. It would contain everything in a highly cohesive format, in one place, and make particular pieces of information particularly easy to find. I realize that this is a very ambitious undertaking, but I find that a unified source of information is better than information with varying levels of quality scattered across more places than one can hold in his head. I just have one question: What is all the necessary material to understand and utilize the low level TeX programming language itself? That is, what do I need to read to learn to be able to read the ConTeXt source code itself (which is written in TeX---and lua, but I can help myself in that regard)? Is the "Low Level TeX" set of manuals all that I'll need, or will I need other sources of information too? And also, is it worth learning Plain TeX, and reading The TeXbook, or is not necessary? And, I'm grateful to have an alternative to LaTeX. It's certainly promising, but I would like to help make it appealing, by making it easy to learn and master it, and provide a single source of information. I'm grateful for having ConTeXt. P.S. If I have bugs to file, should I file them on this mailing list, or on the dev-context(a)ntg.nl mailing list? And, to all beginner ConTeXt users: What would you like to see covered in this book? Thanks. -- Sent with Tuta; enjoy secure & ad-free emails: https://tuta.com

regular online meet-up
by Henning Hraban Ramm 14 Feb '24

14 Feb '24

You’re invited to our regular online meet-up, this upcoming Wednesday, February 13th, 19:00 CET (UTC+1) at https://lecture.senfcall.de/hen-rbr-rku-oke (same, but shorter: https://u.mtxrun.eu/ctxmtg) ConTeXt users of all levels are welcome! Do you have a subject that you’d like to talk about? (I hope I’ll manage to show a poster draft…) Looking forward to seeing you, Hraban (Same blurb as always:) [Howto] * No special software installation required; most modern browsers should work (WebRTC required). * Open the URL above, 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. * Sometimes leaving and re-entering helps. * 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...
