by Taco Hoekwater 22 Aug '23

22 Aug '23

Hi all, This is a reminder that the registration for the upcoming ConTeXt meeting in Sibrina, Czech Republic is still open. The meeting will take place from Sept 10 to Sept 16. You can go to https://meeting.contextgarden.net for more information. You will also find the registration form there. You can (of course) attend in person, but registration for online only attendance is also possible! We hope to see you next month! NOTE: There have recently been problems with the delivery of the filled-in registration form to the organisers. If you have registered sometime *in the last month* but have not heard from Jano or me yet, please re-register (the form emailer is fixed) or at least drop us a message! Best wishes, Taco

your opinion about list structures
by Henning Hraban Ramm 22 Aug '23

22 Aug '23

Hi, this is about my ConTeXt book again… [ToC] At the moment, my table of contents has chapters and sections and is 8 pages long. I would probably hardly use it. Maybe it would be better to show only chapters (29 content + 12 appendix = 2 pages) and include a list of sections after the chapter title (or not at all). [Registers] I split between command and topic index (9 pages each), because I find it annoying to have the commands between the topics. I also include the topics that are mentioned in titles in the index, because I hate it if I must look in two places. (Otherwise I wouldn’t think about omitting the sections from the ToC.) At the moment there‘s also an index of todo items, but that will disappear before print. [Glossary] There’s a short dictionary of technical terms in the appendix (8.5 p.). Each lemma is also included in the index. Should I add a list of abbreviations? (TDS, TEI, OCG, RAL, PDF, SVG…?) They’re in the index and explained where they matter – I don’t think the meaning of many abbreviations like file types is important. [Other lists] Should I include a list of colors, like the output of \showcolor[crayola]? (I think it would only bloat the book, and everyone can create the list themselves.) I have lists of supported languages (should get checked), fonts in the distribution and all math fonts, because these are not easily reproducible (AFAIK). So, what do you think, and how do you like to work with technical books? What kind of information (about ConTeXt or documents/printing in general) do you find hard to find? Hraban

Equivalent of the \cancel command with conTeXt
by Fabrice Couvreur 22 Aug '23

Hi, In an algebraic expression, it is sometimes interesting to cross out terms. With LaTeX, there is the \cancel command from the package cancel. Is there an equivalent with conTeXt ? Thanks Fabrice

Disable continued captions for table parts
by Alexey Kryukov 22 Aug '23

22 Aug '23

Dear list, probably a stupid question, but is it possible to have a table splitted across pages without adding labels to all subsequent table parts except the first one? In my book I have captions above tables (\setupcaption[table][location=top]), so they are expected to behave like normal heading. With this type of formatting any "continued" marks would look weird. -- Regards, Alexey Kryukov <anagnost at yandex dot ru> Moscow State University Faculty of History

hyphenation inside quotation
by Thomas A. Schmitz 22 Aug '23

Hi, is this a limitation or a bug? Text inside \quotation{} is not hyphenated. It appears to be like this for a couple of versions, but I'm not sure if it has always been the case. Silly example to test: \mainlanguage [de] \setuppapersize [A6] \setupbodyfont [14pt] \starttext „Originalgenie“ „Originalgenie“ „Originalgenie“ \quotation{Originalgenie} \quotation{Originalgenie} \quotation{Originalgenie} \stoptext All best Thomas

XML processing beginner's question
by Michael Löscher 22 Aug '23

22 Aug '23

Hello list, having the xml data at the bottom, I would like to process it so that the result is like this: --- What it is (e.g. bold formatted) date: 2023-08-01 (italic) Description (small font size) Another text (small font size) hd1 - Header 1 § 1 First (A first short description) AAAAAAAAAA BBBBBBBBBB § 2 Second (A second short description) CCCCCCCCCC DDDDDDDDDD § 3 Third (A third short description) EEEEEEEEEE FFFFFFFFFF --- How can I process the <element>s differently? The first element contains a <date> tag and so it differs from the other ones. The second element's <name> tag contains the word "Header" which makes it different again. The other elements contain a <shortdescription> tag that they all have in common. What could be the appropriate xml setups to generate the above output? Michael --- xml data: \startbuffer[xmlcontent] <?xml version="1.0" encoding="UTF-8" ?> <document> <element> <mdata> <name>What it is</name> <date>2023-08-01</date> </mdata> <tdata> <content> Description Another text </content> </tdata> </element> <element> <mdata> <num>hd1</num> <name>Header 1</name> </mdata> <tdata> <content> Text of Header 1 </content> </tdata> </element> <element> <mdata> <num>1</num> <name>First</name> <shortdescription>A first short description</shortdescription> </mdata> <tdata> <content> AAAAAAAAAA BBBBBBBBBB </content> </tdata> </element> <element> <mdata> <num>2</num> <name>Second</name> <shortdescription>A second short description</shortdescription> </mdata> <tdata> <content> CCCCCCCCCC DDDDDDDDDD </content> </tdata> </element> <element> <mdata> <num>3</num> <name>Third</name> <shortdescription>A third short description</shortdescription> </mdata> <tdata> <content> EEEEEEEEEE FFFFFFFFFF </content> </tdata> </element> </document> \stopbuffer

Low res output possible?
by jbf 22 Aug '23

22 Aug '23

Just wondering: in programs like InDesign, Viva Designer, it is trivial to produce a low resolution pdf output (useful when exchanging a hi-res file with authors and editors prior to pre-print is difficult). I assume it might be possible to do so in ConTeXt. Currently I use a script (gs) to achieve that once I have the ConTeXt output so it is no difficulty, but if that could be done at time of compiling it would make the process just that bit simpler. Possible? Julian

redefine space to be the same as \␣ similar to knuthian approach
by Carlos 21 Aug '23

21 Aug '23

If I have the following, with these linebreaks as in: {\par But a system cannot be successful if it is too strongly influenced by a single person. {\obeylines Once the initial design is complete and fairly robust, the real test begins as people with many different viewpoints undertake their own experiments.}} and opted to load another font, other than cmr that is, a \frenchspacing approach wouldn't be further required Bear with me here, in the current state, for example, and as long as say «…person.␣{\obeylines Once the initial is complete…» though feasible enough, leaves any prior \␣ at the mercy of whatever fontsize and/or set width happens to be. And this is just plain wrong. Likewise, if a word sequence such as \TeX\ occurs as in {\ss The separation of any of these four components would have hurt \TeX\ significantly. } The next sentence: «If I had not participated…» does not get any \nofrenchspacing which is equally and doubly problematic. It shows lack of consistency. And this ought not to be an ‹either› ‹or› scenario. But rather, an and conjunctional construct. It fails both ways. Furthermore, with the same token, if width is specified with a \setuplayout[width=15cm] Anything less than 12.895pt, especifically for that use case, wwould throw anything, particularly control sequences such as \TeX\ out of whack, and conversely, once a value of that very pt or pica or whatever is lowered, it brings that nonfrenchspacing right back on. And if width increments occur, then it follows that any control sequence kerning also gets thrown off as a result. It seems so far, that with lmtx, any standalone file, document, minimal working example that does not load cmr at the outset does not produce an acceptable outcome either. By saying acceptable I meant to say it namely from a typographical point of view. Nothing else. from the TeXbook 380-381 «\obeylines doesn’t say ‘\def^^M{\par}’, so we must make any desired changes to \par before invoking \obeylines. (2) The \uncatcodespecials operation changes a space to category 12; but the \tt font has the character ‘␣’ in the ⟨space⟩ position, so we don’t really want ␣12 . (3) The \obeyspaces macro in Appendix B merely changes the ⟨space⟩ character to category 13; active character ␣13 has been defined to be the same as \space, a macro that expands to ␣10 . This is usually what is desired; for example, it means that spaces in constructions like ‘\hbox to 10 pt {...}’ won’t cause any trouble. But in our application it has an undesirable effect, because it produces spaces that are affected by the space factor. To defeat this feature, it’s necessary either to say \frenchspacing or to redefine ␣13 to be the same as \␣. The latter alternative is better, because the former will discard spaces at the beginning of each line.» «In theory, this seems like it ought to work; but in practice, it fails in two ways. One rather obvious failure—at least, it becomes obvious when the macro is tested—is that all the empty lines of the file are omitted. The reason is that the \par command at the end of an empty line doesn’t start up a new paragraph, because it occurs in vertical mode. The other failure is not as obvious, because it occurs much less often: The \tt fonts contain ligatures for Spanish punctuation, so the sequences ?‘ and !‘ will be printed as ¿ and ¡ respectively. Both of these defects can be cured by inserting and «When INITEX creates a brand new TEX, all characters have a space factor code of 1000, except that the uppercase letters ‘A’ through ‘Z’ have code 999. (This slight difference is what makes punctuation act differently after an uppercase letter; do you see why?) Plain TEX redefines a few of these codes using the \sfcode primitive, which is similar to \catcode (see Appendix B); for example, the instructions \sfcode‘)=0 \sfcode‘.=3000 make right parentheses “transparent” to the space factor, while tripling the stretcha- bility after periods. The \frenchspacing operation resets \sfcode‘. to 1000.» -- If at first you don't succeed, you must be a programmer.

zint 2.12.0 barcode generator
by Keith McKay 21 Aug '23

21 Aug '23

Hi all, I've updated the zint barcode generator on my mac mini to 2.12.0 and now no barcode is produced. I have this vague recollection that it is only the 2.10.0 version of zint which works in ConTeXt. If I am correct, is ConTeXt likely to be updated so that 2.12.0 works? I originally installed zint with Homebrew. There is a very complicated thread on stackoverflow on how to downgrade to previous versions of a formula in homebrew, but it is far too complicated for my wee brain. Thanks Keith McKay

Inconsistent behavior: \addfontfeature and CLD local function
by Hamid,Idris 20 Aug '23

20 Aug '23

Dear gang, For \addfeature and the like, a virtual font feature defined in terms of a CLD local function behaves differently from other font features. MWE: ============== \startluacode local function squeeze(tfmdata) for k, v in next, tfmdata.characters do v.width = 1.75 * (v.height or 0) v.depth = 1.75 * (v.depth or 0) end end local specification = { name = "sqtfm", description = "test", manipulators = { base = squeeze, node = squeeze, } } fonts.handlers.otf.features.register(specification) \stopluacode \definefontfeature[forceno] [mode=node, script=latn] \definefontfeature[forceyes] [mode=node, script=latn, smcp=force, sqtfm=force] % smcp=yes, % sqtfm=yes] \showglyphs \startTEXpage[offset=1em] \definedfont[texgyretermes-regular*forceyes] % \definedfont[texgyretermes-regular*forceno] % \addfeature{forceyes} abcdefg \stopTEXpage ============== You may toggle these lines: \definedfont[texgyretermes-regular*forceyes] % \definedfont[texgyretermes-regular*forceno] % \addfeature{forceyes} With \definedfont[texgyretermes-regular*forceyes] active we get the expected result: small caps plus some negative squeeze (= spread in this case). With \definedfont[texgyretermes-regular*forceno] \addfeature{forceyes} active we get an *unexpected* result: small caps but no negative squeeze. (Similar results occur if we toggle the "=force" lines with the "=yes" lines, but the larger project of which this is the MWE uses the force key.) Clue: A CLD with a feature defined via fonts.handlers.otf.addfeature doesn't seem to have this problem: ============== \startluacode local function squeeze(tfmdata) for k, v in next, tfmdata.characters do v.width = 1.75 * (v.height or 0) v.depth = 1.75 * (v.depth or 0) end end local specification = { name = "sqtfm", description = "test", manipulators = { base = squeeze, node = squeeze, } } fonts.handlers.otf.features.register(specification) fonts.handlers.otf.addfeature { name = "stest", type = "substitution", data = { a = "X", b = "P", } } \stopluacode \definefontfeature[forceno] [mode=node, script=latn] \definefontfeature[forceyes] [mode=node, script=latn, % % smcp=force, sqtfm=force, stest=force] % % smcp=yes, % sqtfm=yes, % stest=yes] \showglyphs \startTEXpage[offset=1em] \definedfont[texgyretermes-regular*forceyes] % \definedfont[texgyretermes-regular*forceno] % \addfeature{forceyes} abcdefg \stopTEXpage ============== So only the local-function feature appears to exhibit this inconsistency. What is the explanation for this inconsistent behavior? Is there a way to get the expected result for \addfeature etc.? Thank you in advance.

If it had happened, I wouldnt' have had this issue with sizes say at 10pt and 11pt The permissions for these font files are 644 or read permissions only and I wrongly assumed this would be taken care of by the backend, but by the looks of it, it didn't. Anyhow. Thank you for your time Mikael, Wolfgang. you too Hans. -- Seems a computer engineer, a systems analyst, and a programmer were driving down a mountain when the brakes gave out.

The programmer said, "OK, but first I think we should get back in and see if it does it again."

Applying \sc for smallcaps across styles
by Hamid,Idris 19 Aug '23

19 Aug '23

Dear gang, Consider the following typescript template: \definefontfeature [myfont-tf-sc] [mode=node,script=latn,language=dflt,trep=no, protrusion=quality,expansion=quality, compose=yes,combine=yes,tlig=yes, kern=yes,liga=yes,onum=yes,cpsp=yes,smcp=yes, % smcp activie trnsl=force] % synonym mapping \starttypescript [serif] [myfont] [name] \loadfontgoodies[myfontlfg] \definefontsynonym [Serif] [MyFontRegular] [features=myfont-tf] \definefontsynonym [SerifItalic] [MyFontItalic] [features=myfont-it] \definefontsynonym [SerifBold] [MyFontBold] [features=myfont-tf] \definefontsynonym [SerifBoldItalic] [MyFontBoldItalic] [features=myfont-it] \definefontsynonym [SerifCaps] [MyFontRegular] [features=myfont-tf-sc] \definefontsynonym [SerifCapsItalic] [MyFontItalic] [features=myfont-it-sc] \definefontsynonym [SerifCapsBold] [MyFontBold] [features=myfont-tf-sc] \definefontsynonym [SerifCapsBoldItalic] [MyFontBoldItalic] [features=myfont-it-sc] \stoptypescript % font mapping \starttypescript [serif] [myfont] \loadfontgoodies[myfontlfg] \definefontsynonym [MyFontRegular] [file:MyFont-Regular] % [features=myfont-tf] \definefontsynonym [MyFontItalic] [file:MyFont-It] % [features=myfont-it] \definefontsynonym [MyFontBold] [file:MyFont-Bold] % [features=myfont-tf] \definefontsynonym [MyFontBoldItalic] [file:MyFont-BoldIt] % [features=myfont-it] \stoptypescript As is well known, \sc selects the small caps only from the Serif font, not from SerifBold etc. But MyFont has smallcaps for every style. So in the typescript we make that explicit and apply the smcp=yes fontfeature to SerifCapsBold etc. But this does not work: \sc still only applies to Serif or SerifCaps. Now I can load a goodies file myfontlfg and do something like this: local smallcaps = { smcp = yes, } But that does not change the behavior of \sc. Yes, there is an easy workaround: \definefontfeature[smallcaps][smcp=yes] \define\sc{\addff{smallcaps}} This works for all styles that have the smcp feature, but I don't like having to redefine a system command. So the questions are: 1) Is there a recommended\better way to get \sc to work across all styles? 2) Are there any edits you would recommend to the above typescript template? Once we're clear on this, will update this quite obsolete page: https://wiki.contextgarden.net/Bold_small_caps Thank you in advance.

Enable interaction on custom apa cite variant

I have come up with this MWE: \startbuffer[ref] @book{burago2022course, title={A course in metric geometry}, author={Burago, Dmitri and Burago, Yuri and Ivanov, Sergei}, volume={33}, year={2022}, publisher={American Mathematical Society} } \stopbuffer \setupinteraction[state=start, color=blue] \setupcolors[state=start] \usebtxdataset[ref.buffer] \usebtxdefinitions[apa] \definebtx [apa:cite:theorem] [apa:cite] \startsetups btx:apa:cite:theorem \btxflushauthorname{author} \btxcomma \btxflush{year} \fastsetup{btx:cite:righttext} \stopsetups \setupenumeration[ before={\blank[medium]}, after={\blank[medium]}, alternative=serried, right=, headcommand=\groupedcommand{}{.}, distance=0.5em, width=fit, headstyle=bold, titlestyle=bold, way=bytext, conversion=numbers, prefix=chapter, list=all, title=yes, indentnext=no, ] \defineenumeration[definition][ text=Defintion, style=normal, number=no, ] \starttext \startdefinition{\cite[righttext={{ p.\nbsp 1}}, alternative=theorem][burago2022course]} This is something \stopdefinition \startsubject[title={References}] \placelistofpublications \startsubject \stoptext The problem with this is that the citation is not interactive like it would be if I used apa:cite:authoryear and just removed the parentheses in the options. How do I get it to highlight blue and be interactive like the default behaviour when you turn on interaction? Also this is probably overkill so if there is a better way to achieve this... Jethro

Some very simple cld - loading a module
by Hamid,Idris 18 Aug '23

18 Aug '23

Dear gang, The following, simple MWE gives an undefined control sequence error: ======= % \usemodule[translate] % \enableinputtranslation \startluacode -- context.usemodule({translate}) context.usemodule{translate} context.enableinputtranslation() context.darkgreen() \stopluacode \startTEXpage[offset=1em] \translateinput[Hermes][Idris] Hermes \disableinputtranslation Hermes \stopTEXpage ======= tex error > tex error on line 14 in file ./test-luacode.tex: Undefined control sequence <line 3.12> \translateinput [Hermes][Idris] ======= The reason for the error is that the module is not being loaded. Toggling back to context syntax, of course, works. Reference: ConTeXt Lua Documents by Hans Hagen, page 22. The following analogous code works: \startluacode context.startchapter{first} \stopluacode So how do we properly load the module from within a luacode environment? Thank you in advance.

Table head/body via lua
by Alexey Kryukov 18 Aug '23

18 Aug '23

Hi, I am trying to generate a table representation for some xml source. As the data structure doesn't directly correspond to the desired table structure, some manipulations via lua are required. So far everything works OK except table sectioning commands, like \bTABLEhead, \eTABLEhead, bTABLEbody or \eTABLEbody: it seems impossible to incapsulate them into lua functions. For example, the following is not compiled: \starttext \bTABLE \ctxlua{context.bTABLEbody()} \bTR \bTD Cell 1\eTD \bTD Cell 2\eTD \eTR \ctxlua{context.eTABLEbody()} \eTABLE \stoptext Can anybody suggest a workaround (except changing the source XML of course)? -- Regards, Alexey Kryukov <anagnost at yandex dot ru> Moscow State University Faculty of History

Re: Experiments with \doloopoverlist

I was using an old LMTX copy, and that was the issue. Thanks to Hans for pointing that out. Now I'm trying to expand my solution a little more. Is there any way to retrieve an element in a dataset by using the key? For example, given an "authors" dataset, I would like to do something similar to: %% Given this data structure ... \setdataset[authors][ nombre={Andrés Conrado Montoya Acosta}, bio={This is a bio, it could be two or three paragraphs long}, email={loremipsum(a)email.edu.co}, cvlac={ https://scienti.minciencias.gov.co/cvlac/visualizador/generarCurriculoCv.do… }, orcid={https://orcid.org/0009-0007-0765-4241}, gscholar={ https://scholar.google.com/citations?user=GpYTTU0AAAAJ&hl=es&authuser=1}, ] %% I want to do something like.... \startGetAuthor[nombre={Andrés Conrado Montoya Acosta}] \datasetentry{bio}\par email: \mailhref{\datasetentry{email}} \stopGetAuthor So, if my name is found in the dataset, get the data for that name. Is something like that possible?
