PDF forms not creating proper children
by Leonard Janis Robert König 09 Jun '21

09 Jun '21

Hello, I currently try to build a document with AcroForms, e.g., the examples from [1] also linked in the Wiki. The most recent example is in the form/ subdirectory and dated mid 2020. However, when building the file(s) with my ConTeXt distribution the file created is broken, in comparison to the PDF checked in into the Git. The more obvious difference is that the PDF in the repository can be filled in the Firefox 89 beta, while the other PDF doesn't even display the fields as forms. Running pdfinfo also yields: > Syntax Error: Form field child is not a dictionary I suspect that due to some breakage the forms children aren't set in the AcroForms dictionary anymore? My ConTeXt versions are: # ArchLinux Repos context --version mtx-context | ConTeXt Process Management 1.04 mtx-context | mtx-context | main context file: /usr/share/texmf- dist/tex/context/base/mkiv/context.mkiv mtx-context | current version: 2021.03.05 19:11 mtx-context | main context file: /usr/share/texmf- dist/tex/context/base/mkxl/context.mkxl mtx-context | current version: 2021.03.05 19:11 # Debian Buster Repos mtx-context | ConTeXt Process Management 1.02 mtx-context | mtx-context | main context file: /usr/share/texmf/tex/context/base/mkiv/context.mkiv mtx-context | current version: 2018.04.04 00:51 # Docker Image: Current mtx-context | ConTeXt Process Management 1.03 mtx-context | mtx-context | main context file: /context/tex/texmf- context/tex/context/base/mkiv/context.mkiv mtx-context | current version: 2020.01.30 14:13 mtx-context | main context file: /context/tex/texmf- context/tex/context/base/mkiv/context.mkxl mtx-context | current version: 2020.01.30 14:13 # Docker Image: Beta mtx-context | ConTeXt Process Management 1.03 mtx-context | mtx-context | main context file: /context/tex/texmf- context/tex/context/base/mkiv/context.mkiv mtx-context | current version: 2020.01.30 14:13 mtx-context | main context file: /context/tex/texmf- context/tex/context/base/mkiv/context.mkxl mtx-context | current version: 2020.01.30 14:13 # Docker Image: LMTX mtx-context | ConTeXt Process Management 1.04 mtx-context | mtx-context | main context file: /context/tex/texmf- context/tex/context/base/mkiv/context.mkiv mtx-context | current version: 2021.04.14 22:58 mtx-context | main context file: /context/tex/texmf- context/tex/context/base/mkxl/context.mkxl mtx-context | current version: 2021.04.14 22:58 # Docker Image: Beta from 2019-09 mtx-context | ConTeXt Process Management 1.03 mtx-context | mtx-context | main context file: /context/tex/texmf- context/tex/context/base/mkiv/context.mkiv mtx-context | current version: 2019.09.10 20:03 mtx-context | main context file: /context/tex/texmf- context/tex/context/base/mkiv/context.mkxl mtx-context | current version: 2019.09.10 20:03 The ConTeXt version of the checked in file on GitHub is (according to pdfinfo): > Creator: LuaTeX 1.10 7138 + ConTeXt MkIV 2019.08.20 17:20 > Producer: macOS Version 10.14.6 (Build 18G5033) Quartz PDFContext I also remebered another time were I toyed around with it and indeed that PDF also had broken form field children: > Creator: LuaTeX 1.12 7306 + ConTeXt MkIV 2020.03.10 14:44 > Producer: LuaTeX-1.12 A broken version that I built locally using the :current IslandOfTeX [2] can be found at [3]. The version difference between the broken and not-broken PDFs hints that the breakage occured between 2019.08.20 and 2019.09.10-beta, while the Debian breackage might be due to a backport(?) Alternatively, this could just be a mistake on my side?

LMTX problem with doifmode in \setuplayout
by Rik Kabel 08 Jun '21

08 Jun '21

Hello all, Odd issue with LMTX (works fine with --luatex). \doifelsemode causes a failure if it is used to set a simple value such as on, off, yes, no, ..., but works with a dimension. Perhaps better illustrated by an example: \definemode [aaa] [keep] \setuplayout [ marking=\doifmodeelse{aaa}{off}{on}, % marking=on, grid=\doifmodeelse{aaa}{yes}{no}, % grid=yes, bottom=\doifmodeelse{aaa}{10mm}{20mm}, ] \starttext This is only a test. \stoptext The problem occurs whether or not the mode is enabled. In the example, it fails with the mode test in the either the marking= or grid= keys, but has no problem with it in the bottom= key. The error message says: The control sequence marked <to be read again> should not appear between \csname and \endcsname. pointing to the enabled \doifmodeelse line. The same issue occurs with the following, using \doifmode: \definemode [aaa] [keep] \setuplayout [ marking=on, marking=\doifmode{aaa}{off}, ] \starttext This is only a test. \stoptext This did work without complaint a few months ago. -- Rik Kabel

keep text strictly inside box
by Hans van der Meer 08 Jun '21

08 Jun '21

As can be seen in this screenshot, the text overshoots on the right side the boundary of the fairly narrow \framedtext. My intent is to not hyphenate the names, even if that means a ragged edge on the right side. But at the same time the text must absolutely stay within the confines of the framedtext. I played with \raggedright, \tolerance, \looseness, \emergencystretch but no combination of them seems sufficient fto force all gtext inside. Is there another solution to force the text inside the box or do I have to insert linebreaks manually (a nuisance to be avoided, of course.) dr. Hans van der Meer

frameoffset in textbackground?
by Hans van der Meer 08 Jun '21

08 Jun '21

In the following MWE for a textbackground the parameter backgroundoffset has the expected effect. But for positive values only. A backgroundoffset=-10pt has no visible effect. But the real problem is the parameter frameoffset. No effect at all, whatever frameoffset= is set to. dr. Hans van der Meer

randomizer line-breaking
by Steffen Wolfrum 08 Jun '21

08 Jun '21

Hi Hans, is there some kind of randomizer involved in line-breaking? I have a 458 pages project, a book of humanities. When I immediately typeset (engine=luatex) it a second time, the resulting PDF differs on 14 pages, diffpdf-compared to the original PDF when I typeset it a third time, the resulting PDF differs on 7 pages, when I typeset it a forth time, the resulting PDF differs on 12 pages, when I typeset it a fifth time, the resulting PDF differs on 0 pages. "differs" means that there a paragraphs (mostly footnotes, rarely in the main text) that show different line-breaking: This doesn't mean wrong hyphenation, just *different* hyphenation, different each time. As you can imagine, I can't provide a minimal example for this, only the entire project-folder and the entire context-standalone. Steffen

Can't find `t-pgf.tex` and `pgflibrarypgfplots.contourlua.code.tex`
by Gavin 08 Jun '21

08 Jun '21

Hello list, Tik-Z files seem to have gone missing in the ConTeXt. Here’s a MWE: \usemodule[tikz] % Error in current MkIV and LMTX, but OK in TeX Live 2021 \usemodule[pgfplots] % Error in Tex Live 2021 \starttext Hello \stoptext The error is in MkIV is: tex error > tex error on line 21 in file /Users/Gavin/context-osx-64/tex/texmf-context/tex/context/modules/mkiv/m-tikz.mkiv: ! I can't find file `t-pgf.tex'. l.21 \input t-pgf.tex The same error in LMTX. The error in Tex Live 2021 is: tex error > tex error on line 48 in file /usr/local/texlive/2021/texmf-dist/tex/generic/pgfplots/pgfplots.code.tex: ! I can't find file `pgflibrarypgfplots.contourlua.code.tex’. l.48 \usepgfplotslibrary{contourlua} Maybe I’m doing a poor job of maintaining my installations, but maybe this is a problem with the download. Thanks! Gavin

Fwd: help with xtreme tables
by Ajith R 08 Jun '21

08 Jun '21

Hi, I have a table with around 120 rows and 120 columns which fits an A0 paper. I want it to be split so that it fits A4 sized papers. When I tried using xtables : \startxtable[split=repeat,header=repeat] \startxtablehead ... \stopxtablehead \startxtablebody .... . . . .... \stopxtablebody the table rows get split into different pages, but the columns get cut at the right edge of the page. Is there a way to split the columns as well (repeating the first column as necessary)? Also, what is the use of grouping rows within \startxtablenext and \stopxtablenext? Note: I am just typing the outline of the code as the cell definitions is very long and hopefully my requirement is clear without the entire cell definitions. Thanks, ajith NB: Apologies if you get two copies of this email as I am sending this email a second timr as my first attempt appears to have failed

setup parameter problem
by Hans van der Meer 07 Jun '21

07 Jun '21

The code below seems ok in \startsection[title=] but not when I program the parameter collection with \def\setupparameters{\getparameters[prefix]} In that case even [title={enclosed value}] crashes with error message: Use of \doMacro doesn't match its definition. Obviously I am missing something here. What? \def\Macro{\dosingleargument\doMacro} \def\doMacro[#1]#2{#1X#2} The code below shows that it should be possible. \startsection[title=\Macro{arg} no braces needed]\stopsection \startsection[title={\Macro[arg1]{arg2} enclosed in braces}]\stopsection \stoptext dr.

where to break a long header
by Sandra Snan 07 Jun '21

07 Jun '21

I had an unsually long header and it didn't look great: https://ellen.idiomdrottning.org/sateotc1.png A crlf fixes it: https://ellen.idiomdrottning.org/sateotc2.png But then that shows up in the table of contents so that's not a good solution. What is the best practice for this situation?
