Problem with textstyle
by Rik Kabel 18 Nov '23

18 Nov '23

Hello list, The following example does not compile, complaining “Missing number, treated as zero needed to see a number, look up 'weird error' in the index to The TeXbook”: \setuphead [chapter] [ textstyle=cap, ] \starttext \startchapter [title={Oops!}] \input knuth-gpt \par \stopchapter \stoptext Replacing the textstyle /cap/ by any of /bold/, /slanted/, /smallcaps/, and /italic/ results in a clean compilation but the indicated style is not applied. Using a style description like /em/, /\em/, /bf/, /\bf/, /\sc,/ does produce the suggested result. The wiki and mail repository are full of examples with the former style names. Using /style=cap/ (which would change the number as well) also results in a failed compilation, while using /style=bolditalic/ works as it should.

wrong destination types?
by Pablo Rodriguez 17 Nov '23

17 Nov '23

Dear list, I have the following sample: \setupinteraction[state=start, page=name, focus=standard] \starttext a\footnote{b} \stoptext In \setupinteraction, "focus=standard" is ignored when I use "page=name". I mean, link destinations are to the full page and they alter the page view (when the document is not viewed as full page). Sorry, I don’t have other way to say it. I should get (only named destination value): 7 0 obj << /D [ 6 0 R /XYZ 76.84458 722.7349 null ] >> endobj And I’m getting: 4 0 obj << /D [ 1 0 R /Fit ] /S /GoTo >> endobj Could anyone confirm the issue or explain me what I’m doing wrong? BTW, "page=name" is required for references to named destinations in external documents. I get the same results with both LMTX and MkIV from current latest (2023.09.26 18:19). Many thanks for your help, Pablo

Text and Remark
by Ursula Hermann 17 Nov '23

17 Nov '23

Dear List: I would like to have text next to the Remark Number \setupindenting[yes,small,first] \defineenumeration [remark] [location=top,text=Remark,inbetween={\blank[nowhite]},after=\blank,headstyle=bold,margin=1in] \starttext \remark An enumeration (\tex{remark}, in this case) takes the paragraph that follows it as its argument. \remark This is the first paragraph after \tex{remark}. It is part of the remark. This is the second paragraph after \tex{remark}. It is not part of the remark. \startremark This is the first paragraph inside \tex{startremark}. It is part of the remark. This is the second paragraph inside \tex{startremark}. It is part of the remark. \stopremark \subsubremark Presto! \stoptext It should look like: Remark 1 I am here. How can I do that. Many Thanks Uschi

Is there a command in context to force every word in a text to hyphenate? e.g to typeset a text with "ge-dach-ten-streep-jes" Thanks .Floris

Vertically aligned alternating fillers
by Marco Patzer 16 Nov '23

16 Nov '23

Hi! A while back Wolfgang presented a nice solution for alternating fillers: https://www.mail-archive.com/ntg-context@ntg.nl/msg67677.html It works if the text has a constant width. But if the width changes, the alternating look is lost. Is there a way to align the dots vertically even if the text has variable width? Example: \usemodule [visual] \definefiller [pavel-0] [alterntive=symbol, method=global, width=2em, leftmargin=.5em, rightmargin=.5em, symbol=\clap{.}] \definefiller [pavel-1] [pavel-0] [align=left] \definefiller [pavel-2] [pavel-0] [align=middle] \newconditional\PavelState \global\setfalse\PavelState \define\PavelFiller {\ifconditional\PavelState \global\setfalse\PavelState \filler[pavel-1]%% \else \global\settrue\PavelState \filler[pavel-2]%% \fi} \def\oneword {\getrandomnumber\n{1}{100}\fakenwords{1}{\n}} \starttext %% dots are vertically aligned \dorecurse{6}{%% Foo \PavelFiller Bar\par} \hairline %% dots are not aligned \dorecurse{6}{%% \oneword\PavelFiller\oneword\par} \stoptext Marco LMTX 2023.09.04 19:15

context not producing synctex output that my synctex program can use
by Jim 15 Nov '23

15 Nov '23

Hi, I've read the wiki, looked at workflows-synctex.tex, searched the web, and scratched my head, all to no avail. So here I am, cap in hand... When I run context, I get a .synctex file which has some information in it, but I can't find any invocation of synctex to return anything useful. Nor does the okular example in the wiki (https://wiki.contextgarden.net/SyncTeX) work for me. Ocular starts, but always on the first page, regardless of what line number I give it. On the other hand, pdftex creates a .synctex file which my copy of synctex find useful. I am using the synctex from the current version of texlive: This is SyncTeX command line utility, version 1.5 Can anyone either (a) enlighten me on what I am doing wrong; or (b) definitively confirm that context is not currently playing nicely with synctex (the wiki notwithstanding) and I should give up this quest for now. Thanks very much. Jim

Problem with dataset not being populated
by Bruce Horrocks 14 Nov '23

14 Nov '23

I produce a small magazine where the source files are organised into a product and component structure. For each issue, I have a main file with \startproduct <issue no> and then, inside that, several \component[filename] statements, one per article. Each article starts in a standard way, including adding some information to a dataset. At the end of the issue, the dataset information is retrieved to be printed and this is where strange things start to happen. Sometimes the whole issue will compile without problems and the dataset information is retrieved perfectly. I can make edits to both the product file and/or any of the component files and it all recompiles to produce a PDF each time. But at othertimes, something "breaks" and the dataset can't be retrieved or isn't created. Everything else compiles fine but there is simply no data being retrieved from the dataset so nothing to print. If I go back to the product file and comment out most of the components then it will (99% of the time) 'unbreak' itself and the dataset gets created. Once it has started working again I can then uncomment the rest of the components and it will recompile with all the dataset data present ... until the next time. Has anyone seen anything like this? I'm using Lua to retrieve the dataset info and, when it goes wrong, the dataset returned by Lua is a nil value. But the .tua file (not a .tuc) has the full dataset structure included. I can't produce an MWE as I have no idea what to remove and include - it doesn't seem to matter which components are left or removed in order to fix the problem just as long as several ar removed. In other words, it's not one component file causing the problem. And sometimes commenting out just two components will fix it, othertimes I have to do most of them. It could be a caching issue - when it goes wrong, reprocessing the product file causes much less to scroll past on the TeXShop log display. And when it is fixed, the first successful run has a much longer log, suggesting that more is being processed. So, unless someone else has seen the above and has the solution, the first question is: does LMTX cache the result of previous runs to save reprocessing if nothing has changed? If so, how can I force a full reprocess or remove those cache files? I'm using TeXShop to edit and compile, but running "context product_filename.tex" from the command line makes no difference.

\doifemptyelse issue?
by Bruce Horrocks 14 Nov '23

14 Nov '23

The following MWE gives "false false" instead of "false true". I'm sure this used to work (18 months or more ago!) as I found it when re-processing an old document. ---start--- \setdataset [DS] [a=aaaa] \setdataset [DS] [a=] \starttext :\datasetvariable{DS}{1}{a}: \crlf :\datasetvariable{DS}{2}{a}: \crlf \doifemptyelse{\datasetvariable{DS}{1}{a}}{true}{false} \doifemptyelse{\datasetvariable{DS}{2}{a}}{true}{false} \stoptext ---end--- ConTeXt ver: 2023.09.26 18:19 LMTX There is a work-around using \doiftext instead as that seems to work okay with recalled dataset values but I thought I'd raise it. — Bruce Horrocks Hampshire, UK

named destinations in /GoToR
by Pablo Rodriguez 14 Nov '23

14 Nov '23

Dear list, imagine I have a PDF document (named "whatever.pdf") such as the one generated from this source: \setupinteraction[state=start, focus=standard] \starttext \dorecurse{5} {\chapter[\recurselevel]{Chapter} \section[sec-\recurselevel]{Section}} \stoptext This source only samples PDF documents not generated with ConTeXt. This means that no .tuc file may be available and named destinations may contain only digits. Then I need to access some named destinations from a document such as: \setupinteraction[state=start, focus=standard] \starttext \dorecurse{5} {\goto{Chapter \recurselevel}[whatever.pdf::\recurselevel], \goto{section \recurselevel}[whatever.pdf::sec-\recurselevel]\par} \stoptext Sorry, but after reading again lpdf-ano.mkxl I’m not sure whether I can get named destinations (such as "/D (4)" or "/D (sec-3)") and how I could get them. With the previous code, the only destination reads in the PDF source: 5 0 obj << /D [ 0 /Fit ] /F (whatever.pdf) /S /GoToR >> endobj Many thanks for your help, Pablo

hard clipping in ConTeXt?
by Pablo Rodriguez 13 Nov '23

13 Nov '23

Dear list, I have the following sample: \setuplayout[page] \starttext \clip[hoffset=5mm, voffset=5mm, width=15mm, height=15mm] {\externalfigure[xml-mkiv.pdf]} \stopnotmode \stoptext Using PDF.js (from current Firefox), xpdf, Evince, mupdf-gl, the viewer is able to find "dealing", altough it cannot be displayed. Okular and Sumatra (with Wine in Linux) are not able to find "dealing". Is there any way to have a hard clipping in ConTeXt? I mean, that only the contents of the clipped section is added to the resulting PDF document? Many thanks for your help, Pablo
