Re: [NTG-context] LuaTeX incompatible with Lua
Below I include a suggestion on how to do this sort of version agnostic.

As you can see from the example, this comes with the additional
complication that LuaJIT has Lua 5.1 behaviour and should also retain
that.

[NTG-context] setup according to total numbers
Hi Hans, this is related to a previous message (https://mailman.ntg.nl/pipermail/ntg-context/2019/096253.html). I don’t know how hard could to implement them, but it would be useful to be able to setup xtables and lists based on the total number of columns, rows and items. Some cases would be: - Set a different width in list if their total number of items is more than 9 and another one if items are more than 19. - List iwith alphabetic numbering when it contains fewer items than 5 and with digits in other case. - Stretch xtable to width, if it contains more than 4 columns. - Stretch xtable to height, if it contains more than 10 rows. Sure, there may be plenty of other cases in which being able to setup xtables and list based on the total number of their elements would be handy. I wonder whether it would be possible to have commands that provide the number of these elements to be used to set them up.

[NTG-context] two issues with inmargin attachments
Hi Hans, I have the following sample, using latest beta from 2019.11.14 17:07: \setuppapersize[A5] \showframe \setupinteraction[state=start] \setupinteractionscreen[option=attachment] \starttext a\attachment[file=xml-mkiv.pdf] b\attachment[file=mkiv-publications.pdf] c\attachment[file=onandon.pdf, location=inmargin] d\attachment[file=notnow.pdf, location=inmargin] e\attachment[file=about.pdf, location=text] f\attachment[file=i-context.pdf, location=text] \stoptext The default location seems to be "text", but when specified as option it prevents the attachment. The general configuration for location may be different, but in that case it seems impossible to use "text" for a single attachment. "location=inmargin" seems to place all /FileAttachment annotations on the same place (when from the same line, they have the same /Rect), as shown in the excerpt: 21 0 obj << /Type /Annot /NM (attachment:3) /Subtype /FileAttachment /Rect [ 35.54572 493.13349 41.52002 499.1078 ] >> endobj 22 0 obj << /Type /Annot /NM (attachment:4) /Subtype /FileAttachment /Rect [ 35.54572 493.13349 41.52002 499.1078 ] >> endobj Would it be possible that inmargin attachments allow more than one from the same line?

Re: [NTG-context] ConTeXt as a service
Hi! I’m running ConTeXt on my web server e.g. to generate shipping forms for a customer. As Hans said, it makes sense to use an asynchronous setup; in my case it’s celery/RabbitMQ behind Django. You probably need to set a few environment variables: I find HOME, PATH, TEXROOT and TEXMFOS in my setup. I don’t know if you really need all of them, it’s already running for several years… Also your web server process might only run binaries that belong to some user/group like wwwrun. It won’t work in shared hosting, because you can’t install your own programs. Otherwise: What kind of documentation do you need? Installing ConTeXt on a (web) server is not different from any other Linux system. Calling ConTeXt from a web application is not different from calling any other external program. The rest depends on your setup and web frameworks.

Recalculating the results of invoked Luacode functions might be the best and simplest choice, because finding a good hash key for a lua table which must be created by the ConTeXt/Luacode program page itself could become rather difficult (one could get into devil's kitchen, as we say). On the other side one single lua table only for the current run, similar to .tuc files, is helpful and necessary to have a look onto the results of the used luacode functions. Sometimes they are the only help in error finding.

This code does not work, and reverts to the default font:
|\definefontfamily[mainface][serif][My Font][tf=file:./fonts/MyFont.otf,

However, if I copy the |.otf| files into the same directory as the
|.tex| file, and write |tf=file:MyFont.otf| etc, then everything works
fine.
How do I specify a relative path to the font, inside the |.tex| file?
In LaTeX, I would use |fontspec| package and do the following:
|\setmainfont{MyFont.otf}[Path =./fonts/, ItalicFont =MyFont-It.otf]|
However, I couldn't find the equivalent syntax for |\definefontfamily|
in ConTeXt.
Just to mention, I am using ConTeXt version: 2019.03.21 21:39 as part of
TeX Live, on Manjaro Linux.
It is normally a bad idea to have fonts in such a place. You never know
how it will clash with other fonts (versions, similar names, etc).
In context, we have
tex/texmf-fonts
so best is to use:
tex/texmf-fonts/data/MyFont-It.otf
etc, them run mtxrun --generate and let the system sort it out.
Another option is to set the RUNTIMEFONTS environment variable.
Like:
\starttext
% \ctxlua{fonts.names.addruntimepath("./myfonts")}
\ctxlua{os.setenv("RUNTIMEFONTS","./myfonts")}
Hello World!
\definefont[myfont][file:myfont.otf]
{\myfont Hello World!}
\stoptext
But .. you need tio wipe such a font from the cache when you move it and
other projects using a different font with the same name can be in
trobles. Fonts are best managed very careful as they are responsible for
long term inconsistencies.
There is no official interface from tex this (maybe WS has a suggestion
that fits into the definefontfamily subsystem)

Re: [NTG-context] context command line interface documentation?

You said that context stops when encountering an error which isn’t the case for me.

Re: [NTG-context] Exchangeing content of variables between luacode and context
On 11/19/2019 8:34 PM, Rudolf Bahr wrote: 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. nearly always context is th emaster (it is anyway as it manages the process) 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. can be done in tex of lua - 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. that can be done runtime ... - To estimate the shift amount of all columns together in order to horizontally get them centered on the page. can be done by tex or lua 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. you can store info in the tuc file (there are examplex on the wiki and in the test suite) or you cam create a table, save it at the end of the run and load it at the start (assuming that you cannot just recalculate the values each run, but i assume that you have a reason for not doing that) 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. if each page can be recognized you can make a hash of its properties and store the page specific data using that hash 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. unrelated 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 ___
