Re: [NTG-context] Exchangeing content of variables between luacode and context
Hi Rudolf, storing variable states within the script sounds like AppleScript… Why don’t you write your settings into some file (a Lua table representation would make sense, otherwise something like JSON or INI) and read that in in every run, if it exists?

Hi Pablo,
I can reproduce the issue on MacOS on Acrobat Reader, and also on Adobe Acrobat
Pro.
In fact turning off any last viewerlayer makes the text disappear.

Hi Henri,
many thanks for your reply.
This is really weird, since I cannot make it work, either with Acrobat
in Windows nor in Evince or Acrobat in Linux.
I’m using latest beta from 2019.11.14 17:07 (either MkIV or MkXL). Which
beta are you using?

Works for me on both Evince and Foxit Reader. I can't test Adobe because I'm

Try also \dontleavehmode\llap{\ConTeXt} because \llap by itself does not start

My 'actual problem' is more or less a design problem: Should in a book project ConTeXt be the master and Luacode the slave or vice versa? Both seems possible. The task to solve is to set a photo album with say 300 DIN A4 landscape pages. On every page there should be 1 to 4 columns filled with photos and texts mostly defined in layers. Up to now I made all in ConTeXt manually by trying, for instance:: - To estimate the width of layers, if neighboured layers should contain photos of same height with respect to center horizontally all columns at end of page. - To complete abbreviations of long picture names; it's rather annoying doing this by copy and paste with hundreds of photo names; instead I'd like to type a short code and Luacode should complete it to the full name. - To estimate the shift amount of all columns together in order to horizontally get them centered on the page. All of these tasks can be made best by Luacode functions. And I'd like to save their results in the ConTeXt program permanently. With 'tokens.setters.macro()' it's possible only in the same, Luacode calling ConTeXt run. In the following run, the macro shows its original value again and the Luacode program must be called again to alter it. So I've to think about making Luacode the master and ConTeXt the slave. Then it'd be possible to embody Luacode's results permanently in the ConTeXt code. Vice versa a solution could be to store Luacode's results in a flattened Lua table on disc. But the perfect relating to their ConTeXt page remains difficult when inserting or deleting of pages in an ensemble of 300 pages should become necessary. Another much simpler solution would be the proposal above, namely, to copy the ConTeXt program step by step and page by page to another file and introducing the Luacode results simultaneously. In [1] there is a chapter with "stepper" commands, but I didn't understand that, so I can't say, whether they are suitable for this issue.

Re: [NTG-context] context command line interface documentation?
That’s pretty cool, overriding that hook allows to build a ConTeXt language server for editors like VS Code! https://microsoft.github.io/language-server-protocol/ Sadly I’m still a bit lost: When calling `context file_with_error.tex`, I see “This is LuaTeX, Version 1.10 … tex error on line … ?” and it waits for input. You said that context stops when encountering an error which isn’t the case for me. Any ideas why? Best, Philipp Am Di., 19.

[NTG-context] layers and \llap
Hi Hans,
this comes from a previous message about an issue with \llap and layers.
Here is the sample:
\defineviewerlayer[print][state=stop,printable=yes]
\defineviewerlayer[view][state=start,printable=no]
\starttext
\startviewerlayer[view]\color[red]{\TeX}\stopviewerlayer%
\startviewerlayer[print]\llap{\ConTeXt}\stopviewerlayer%
\input zapf
\stoptext
If the layer with \llap is placed last, disabling the view layer
disables all the text.
Everything works fine if the layer with \llap is placed first.
I guess this might be a bug.
Many thanks for your help,
Pablo

The way I tested this is I inserted the above stanza (with the appropriate object ID) into the uncompressed LMTX PDF, and that was all it took for the calculate JS to start working for the total field. (I likely wrecked the xref table in the process, but the PDF was still functional...) I then built a form with a chained calculation (a second field that doubled the total field) and ended up with a CO entry like this: /CO [13 0 R 19 0 R] ...and I believe that the order of the objects in this array is how the calculation precedence is determined. So! This is bigger than just adding the CO array to enable calculations; there needs to be enough of an interface to also indicate calculation order somehow in the .tex file.

Re: [NTG-context] context command line interface documentation?
Hi, What you’re describing is the behavior I’m trying to achieve. The error location reporting works for me, but context will still continue after an error for me: If I don’t specify --nonstopmode or so it’ll try to recover, and even when I specify it, there will be other output after the error. What version are you running? The latest lmtx should quite after an error. When no proper document can be created it will provide an error document. Not that the script actually expects quotes in argv? The command line parsing is kind of special - lua(metatex) itself has to intercept some flags and act on it - the context (and mtxrun) script also need them (as script) - some passed arguments are used to drive the process - and potentially common flags should not interfere --foo --foo=bar --foo="bar bar" filename "file name" should all work (also with special characters but of course there can be issues i don't know about); so intrepretation happens in the engine, in mtxrun (script0, context (script), context (macro package) when you run context you can see the exact call to luatex and how arguments get passed (some get prefixed with "c:") concerning the wiki, best discuss that with Pavneet (in cc) as he's in charge of (re)organizing the wiki; if you have suggestions for any of the manuals in the distribution that deal with this, you can just sedn them to me thanks, Hans - Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl - ___ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://context.aanhet.net archive : https://bitbucket.org/phg/context-mirror/commits/ wiki : http://contextgarden.net ___
