How to isolate serious errors from warnings?
by Joel 20 Apr '24

20 Apr '24

I'm about to have a lengthy (2,000+ page) document published. Normally if it compiles and looks okay, I regard that as meaning no errors appeared, but I've noticed that sometimes ConTeXt will still compile, even if something isn't displayed on screen as it should: (1) I tried placing a table inside a startitemize environment, as instead of it not compiling, it left a message in the document warning that wasn't supported. (2) In another case, I had an image that ConTeXt couldn't find, as I mispelled the filenmame, and it fully compiled and made a PDF, without me noticing. (3) Or maybe in some case, a font couldn't be found for a specific character, so a single character in the file isn't displaying. Those are just some examples; I intended for something to be printed on the PDF, but it isn't showing there. Since a document of this size will have a lot of messages, is there a way to adjust the settings, from "show everything" to "show some" to "show only serious errors"? Or maybe to use > to send the errors to another file for careful study? (using Linux if that matters) --Joel

Re: Weird (?) float placement for specific widths of image
by denismaier＠mailbox.org 19 Apr '24

19 Apr '24

Hi again, just a quick follow up on this one. Can anyone reproduce this? Would be good to know how this can be fixed. I have this in a real document, and as I'm typesetting a XML source I cannot just adjust slightly adjust the dimensions to get rid of that. Best, Denis Von: denismaier(a)mailbox.org <denismaier(a)mailbox.org> Gesendet: Mittwoch, 10. April 2024 13:37 An: 'ntg-context(a)ntg.nl' <ntg-context(a)ntg.nl> Betreff: Weird (?) float placement for specific widths of image Hi, another graphics/floats question: consider the following example %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% \setupexternalfigures [location={local,global,default}] \starttext \placefigure{A Cow}{\externalfigure[cow][ height=.5\textheight, ]} \placefigure{A Cow}{\externalfigure[cow][ height=.3\textheight, %height=.4\textheight, ]} \placefigure{A Cow}{\externalfigure[cow][ width=3cm, %width=2cm, ]} \placefigure{A Cow}{\externalfigure[cow][width=2cm]} \placefigure{A Cow}{\externalfigure[cow][width=2cm]} \stoptext%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% On the first page, the images appear stacked above each other while on the second page they appear next to each other. It took me some time to reproduce this behaviour, and I can't claim to understand what is happening. But it seems to be related to the specific widths of the images. When I change them to other values the behaviour disappears. Is this a bug? Anything I can do about this? Best Denis

preventing column break after section title
by Peter Münster 18 Apr '24

18 Apr '24

Hi, How could I prevent a column break after the second section title please? Minimal example: \starttext \startcolumns[n=2] \section{title 1} \dorecurse{22}{bla\par} \section{title 2} % Here starts a new column. \startitemize \dorecurse{15}{\item bla} \stopitemize \stopcolumns \stoptext I’ve tried "\setuphead[section][after={\columnbreak[no]}]", but it does not help. TIA for any hints, -- Peter

Most recent context doesn't like synctex?
by Jim 15 Apr '24

15 Apr '24

Hi, I have both TeXlive 2024 and the stand-alone ConTeXt distribution on my system. Recently, the stand-alone ConTeXt distribution seems to not create a synctex file any more. Specifically, /usr/local/context/tex/texmf-linux-64/bin/context --once --texutil --synctex=1 --nonstop file.tex does not create a .synctex file (and deletes it, if it is there), whereas the TeXlive version /usr/local/texlive/2024/bin/x86_64-linux/context --once --texutil --synctex=1 --nonstop nwg_newsletter_2024_04.tex does create the .synctex file. The ConTeXt distribution version *does* create the file if --nonstop is *not* used. Knowing that, I can work around this for now, although emacs+auctex probably won't be happy without --nonstop. I updated the stand-alone ConTeXt a few minutes ago, so I'm up to date on that. Is this a bug introduced by some recent change? Thanks. Jim

[ using horizontal table lines ]

\getmarking for top at the current page
by Biblio＠mail.de 15 Apr '24

15 Apr '24

Dear list, I've got a problem. Not the first one, but the first one to contribute to the list. ;) system> ConTeXt ver: 2024.04.01 08:59 LMTX fmt: 2024.4.12 int: english/english system> 'cont-new.mkxl' loaded %========== %========== \definehead[Datum][subsubsubject] \startsetups[Test] Pr=(\getmarking[Datum][previous])~ Nx=(\getmarking[Datum][next])~ Fi=(\getmarking[Datum][first])~ La=(\getmarking[Datum][last])~ Tp=(\getmarking[Datum][top])~ Bt=(\getmarking[Datum][bottom])~ Cu=(\getmarking[Datum][current])~ \stopsetups \setupheadertexts[text] [\setups{Test}][] [\setups{Test}][] \setuppagenumbering[location=footer] \starttext \startDatum[title={secA}]% \dorecurse{50}{aaa } \pagebreak \dorecurse{50}{aaa } \stopDatum \startDatum[title={secB}]% \dorecurse{630}{bbb } \stopDatum \startDatum[title={secC}]% \dorecurse{50}{ccc } \stopDatum \startDatum[title={secD}]% \dorecurse{50}{ddd } \stopDatum \startDatum[title={secE}]% \dorecurse{50}{eee } \stopDatum \stoptext %========== %========== I'd like to write the marking of the very first text at the current page to the header. That seems to be a bit tricky, at least for me. (I'm afraid that \getmarking[xxx][top] was intended for that and it is not feasible at all.) At page 1 the header should read "secA", at page 2 again "secA" (because the very first text belongs to "secA"), and at page 3 "secC" (because the very first text (the section title) belongs to "secC"). Unfortunatly \getmarking[][] does not behave like I expacted. I understand the keywords of \getmarking in the wiki (https://wiki.contextgarden.net/Command/getmarking) as listed below: • previous: marking at the bottom of the page BEFORE the current page (no page before then empty) • next: marking at the top of the page AFTER the current page (no page after then bottom of current page) • top: marking at the top of the current page • bottom: marking at the bottom of the current page • first: first marking that starts at the current page (no first than behaving like top) • last: last marking that starts at the current page (no last than behaving like bottom) • current: last stored marking while deciding on pagebreaking between the current page and the (potential) following page • default: first According to these thoughts, I started with \getmarking[Datum][top]. But "top" seems not to work, there is no difference between "top" and "first", "top" behaves like "first". My second thought: Generally \getmarking[Datum][first] would be perfect, so I've thought something like \doifelse{\fetchmark[Datum][next] of the page before the current page}{\fetchmark[Datum][previous]} {\getmarking[Datum][previous]} {\getmarking[Datum][first]} could work. (Honestly I don't know how to do "\fetchmark[Datum][next] of the page before the current page}". The first page would need a special treatment too.) But: At page 2 \getmarking[Datum][next] (Nx) contains "secB" but at top of page 3 is not "secB" but "secC". So \getmarking[Datum][next] does not seem to contain the correct information I need, therefore I don't get any further. Any ideas: How do I write the marking of the very first text at the current page to the header? Thank you in advance, Matthias

Is TIFF image no longer supported?
by Joel 14 Apr '24

14 Apr '24

I have a document with PNG, JPG, and TIFF. When I try using \externalfigure[filename][frame=on, width=.6666\textwidth] it displays JPG and PNG fine, but the TIFF files don't render. Is TIFF not supported in ConTeXt anymore? --Joel

Wiki - question about Command/ pages which start with a space character
by garulfo＠azules.eu 14 Apr '24

14 Apr '24

Hi all, Is it on purpose that 128 pages "https://wiki.contextgarden.net/Command/ xxxxxxxx" start with a space character ? I didn't find an explanation in https://wiki.contextgarden.net/Command For example, these two pages exist : - https://wiki.contextgarden.net/Command/startbuffer - https://wiki.contextgarden.net/Command/_startbuffer If it is on purpose: - What is the purpose, and which page should contain which documentation? If it is not: - Is there a way to automatically merge the content of the couple of pages, and to remove the "wrong" pages, or should it be done manually ? Thanks for your help.
