Re: [NTG-context] Convertnumber with \ref[number] fails in MkIV, works in LMTX
Following up on my own note, I see that this fails under LMTX if
compiled in a clean directory, but succeeds if first compiled with the
troublesome line removed, and then, restoring the line, compiled a
second time. It also works by placing a .tuc file from an older version
of the document into the directory before compiling. Very strange
indeed. The expected output, from one of those successful compilations:
So. I am clearly doing something wrong, but sometimes LMTX is letting me
get away with it.

Re: [NTG-context] getting number from context.figurewidth
Hi, Pablo. I have no idea of what you need to do, but in grph-inc.lua you
find the following (line 709):
implement { name = "figurestatus", actions = { get, context }, arguments
= { "'status'", "string", "string" } }
So that \figureheight calls this function via \clf_figurestatus and, in
turn, it calls figures.get. If I'm right,
figures.get('status','height','0') -- or '"status"' ?
would have to return the value you're asking for (at the TeX end, "sp"
units are added). A MWE wouldn't hurt. I hope this helps or, at least, it
leads you through the right direction.
Cordially,
Jairo

it depends abit on what gets flushed, in those cases a low level flush

Sorry, it was the wrong order:
\expanded{\goto{\hyphenatedurl{\xmlflush{#1}}}[url(\xmlflush{#1})]}
\xmlpure is for \hyphenatedurl, not for url.
But your plain \goto is what I use and I have been using it without
problems for long.

I've had a problem with special characters in URLs. Wolfgang suggested to use
\expandUx: https://www.mail-archive.com/ntg-context@ntg.nl/msg95959.html

Hi Denis,
in my environments to typeset XML sources, I never need \expandUx, why
do you needit?
Another approach (I don’t know whether this will work in your real-world
document) might be using \xmlpure instead of \xmlflush as in:
\goto{\hyphenatedurl{\xmlflush{#1}}}[url(\xmlpure{#1})]
The background for both commands can be found on
https://www.pragma-ade.com/general/manuals/xml-mkiv.pdf#page=103.
I hope it helps,
Pablo

[NTG-context] XML-processing: Error with hyphenatedurl
Hi,
I've receiving errors that seem to be related to hyphenatedurl. The problem is
I cannot really reproduce it in a MWE. The example below works, but if I
include the link in my real document, I'am getting this error message (copied
from -error.log):

}
Two things seemed to make it work:
1. Remove the link.
2. Comment out \expandUx in this setup:
\startxmlsetups xml:ext-link

\expandUx % commenting this out makes it work
