[NTG-context] \doifnotdocumentargument in proper Lua
Dear list,
I have the following command in one of my documents:
\doifnotdocumentargument{no-metadata}
{\ctxlua{document.transfer_metadata(document.main_file)}}
Which would be the right way to write \doifnotdocumentargument in proper
Lua?
Many thanks for your help,
Pablo

[NTG-context] Fuzzy paragraph when exporting to XML
Hi, I am trying to debug a bug-report for t-vim: https://github.com/adityam/filter/issues/64 Exporting with trackers=export* gives a warning: backend > export > fuzzy paragraph: I have managed to narrow it down to the attached MWE (which does not depend on the t-vim module at all). Compiling it using $context --trackers=export\* lines gives the fuzzy paragraph warning. Any hints on how to resolve this? Thanks, Aditya lines.tex Description: TeX document ___ 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 ___
Re: [NTG-context] Problem with a defined colour in MetaFun
Hi Wolfgang,
Thank you for your reply. I did as you suggested but it still never
worked. However it did make me delve further into the Metafun,
LuaMetaFun and the Colouring ConTeXt manuals where I found examples of
the *resolvedcolor* helper which I used as follows:
definecolor [name = "myColor", r = uniformdeviate(1), g =
uniformdeviate(1), b = uniformdeviate(1)];
for loop..
fill unitsquare xscaled 5cm yscaled .5cm shifted (7cm,i*cm)
withcolor(r[resolvedcolor("myColor"), white]);
endfor;
I also found the *namedcolor* helper and I could use it as follows:
fill unitsquare xscaled 5cm yscaled .5cm shifted (1cm,(2*i)*cm)
withcolor namedcolor("myColor2") ;
However, for some reason it did not work in:
fill unitsquare xscaled 5cm yscaled .5cm shifted (7cm,i*cm)
withcolor(r[namedcolor("myColor"), white]);
//
Thanks again for your suggestion//
Best Wishes
Keith//

Hi,
In the MWE below I define an rgb colour, myColor1, using random
numbers for the r, g and b components. I then use it to fill a
unitsquare the size of the page, which works as expected. In the loop
that follows I then use the defined colour, myColor1, along with
white and the variable r to create shades of myColor1 as in the MWE
below. However, myColor1 is not recognised in the loop and seems to
be replaced by black, although if I use a predefined colour, in this
case BurntSienna from the crayola collection, it works as expected.
I have tried a number of ways to get this to work as shown in the
code but without success. I would be grateful for any suggestions.

Remove the backslash in front of the definecolor command.

Hi Fabrice
Thank you for your reply. It works the way I wanted. Wolfgang also
replied and this has lead me to an alternative method. See my reply to
him in this mailing list.

Re: [NTG-context] lua-widow-control module error in LMTX
Now, I don't have any widows in my document, and I only count 2 broken hyphens. However, I think this is at the expense of the shenanigans the module has "perpetrated" elsewhere, because, apart from the crazy horizontal spacing of some paragraph in the bibliography, the module lies to me in the log. Yes, the log output fools me. There is no "Widow/Orphan NOT removed". But this is not true: To the 2 broken hyphens must be added 4 orphan lines that the log claims to have resolved. But what worries me the most is that it counts as successful one occasion with an empty line, another occasion with two empty lines in a row, and 4 occasions with no less than 7 empty lines in a row at the beginning of a chapter. I don't know if this information can provide any more clues to adjust the module for the grid mode, but I hope it helps. Greetings, Edu.

Well that's why it was a beta :) Looks like I made some questionable assumptions about the order of the hlist/baselineskip nodes, so the module completely broke with things as simple as section headings.
