Re: [NTG-context] nbsp in XML (S01E01)
Hello,
the first episode was more dramatic than expected, seem to be a good series.

After the patch, nbsp is working as expected.

Useful information, thanks, wikified.
And tilde in XML is just that: the ascii tilde glyph.
Yep, but \xmlfilter can process them nicely. See some next episode.

It didn't occur to me to change it by preprocessor to the new xml elements.
You are right, one can even have more control.
Thank you all for your help,
Jano
And thanks for watching!

You are never going back to “TeX mode”: the preprocessor converts XML into
*other* XML.
And tilde in XML is just that: the ascii tilde glyph.

I agree with that, but for fine-tuning XML output I would use a trick like this:
\startluacode
function lxml.preprocessor(data)
return string.gsub(data, "nbsp;", "")
end
\stopluacode
\startxmlsetups xml:name
...
\xmlsetsetup{\xmldocument}{document|nbsp}{xml:name:*}
\stopxmlsetups
\startxmlsetups xml:name:nbsp
\penalty1\hskip .3em plus 2em % or something, just a wild example.
\stopxmlsetups
Using an xml element would also allow your code to ‘look around’ to make sure
all is
well with its (typesetting) environment.
Best wishes,
Taco

Dear list,
first episode of series on nbsp of XML in lmtx.
Unfortunately, not that catchy as Netflix.
Used XML input has two types of non-breakable space:
* unicode character
* html entitity (in fact an ugly output of HTML editor)
HTML is preprocessed with ctx preprocessor (great feature!) and
substituted for unicode char nbsp or tilde.
MWE shows unichar spaces are non-breakable (see end of the first lines),
however they are not stretchable (see second line of the paragraphs).
Does unicode nbsp have fixed with in ctx?
When tilde is the replacement in preprocessor (uncomment first
replacement in preprocessor), xmlfush will display tilde (which is, as
character, non-breakable and unstretchable, no surprise).
Why tilde is displayed?
Replacing or adding nbsp (tilde) with finalizers have different results,
see next episode after this one is understood.
Thank you,
Jano
