[NTG-context] \goto works but links don't when passed via textext() in METAPOST
I am trying to get an URL link in a textext() via METAPOST. I’ve got this
before \starttext (or after, tried both):
\setupinteraction
[state=start,
color=blue,
style=bold]
The intended link shows up in blue and bold, but it is not clickable.
I’ve turned ConTeXt tracing on and see this when the text is passed to METAPOST:
cld > tex > f : 8 : picture pic; x:=1233.000; y:=913.000;
w:=180.000; h:=407.000;pic := Label( w, h, (1.000,1.000,0.784), 1.0, 1.000,
(0.000,0.000,0.000), 1.000, "dashed evenly", 1.000, (0.000,0.000,0.000), 1.000,
"", "\definebodyfont[11pt][rm][default=Regular at

The red is what is being typeset, the \goto is part of that.
And later this when METAPOST passes it on to TeX via textext():
cld > tex > f : 8 : \definebodyfont [11pt][rm][default=Regular at

the book, including the free excerpt, for a full explanation)\\}}
Still correct. But the end result doesn’t have a working hyperlink. Outside the
route to METAPOST, the \goto statement does produce a working link.
Should this work when passed via textext()?

[NTG-context] Would it be possible in LMTX to do something like variable font/lineheight to fit a fixed frame?
Suppose I have a fixed sized frame, say 3 y 4 cm. And I have a variable-length text. Would it be possible to write a macro that scaled the font and line height such that the text will fit in the frame? What I have now is very basic: Fixed width Typeset (METAPOST textext()) If too high METAPOST: scale down so it fits in frame But the scaling wil scale both height and width so it doesn’t only go to the correct height, it also gets too narrow. Just scaling in the vertical direction squashes the text/font. What would be great is some way to have the font size and lineheight result from TeX trying to fit it inside a predetermined size. Doesn’t need to be perfect, a good approximation will do. I’ve been thinking about using the surface size difference between desired box size and the result of textext() as an approach to guess a right fontsize and line height. What could make it possible for me too is a way to do a typeset command from lua that gives me the box sizes of typesetting without actually typesetting it to the true output of the job. Something like typeset a piece of text without actually outputting it to the PDF output in a width (say 4) get the width and height of the result (say 4 x 6) Adapt front size and lineheight (from 4x6 to 4x3 means a 50% reduction, which may be too much as the result may have just a syllable on the last line) typeset for real in 50% size Is that doable? Or is there a better way?

Re: [NTG-context] Retrieving original value of enviroment variable HOME
Hello, Hans,
I've just renewed the Ctx Beta installation, but 'environment.oldhome'
seems be unavailable.
Was I "too quick" with renewing Ctx?
Testing sample:
\starttext
Ahoj
\startluacode
context(environment.oldhome or "??")
\stopluacode
\stoptext
- prints "??".
I also attache the "status-of-update.lua" and the batch
"first-setup.bat" (maybe a bit obsolete, but working so far) I used to
renew Ctx.
Also result of "dir /s" is available here (~84 k packed):
http://leteckaposta.cz/302654804
What am I doing wrong?
Best regards,
Lukas

You can check it. Btw, when you're using lmtx there should be no real
differences between for instance unix and windows, although on windows
lmtx does support wide characters in environment variables, command
line arguments, filenames, filelinks etc. (not that that matters much
as one will seldom use more than ascii). Specific environment
variables like HOME are a bit tricky on windows as they come in
variants, so let me know if some more magic is needed.

are you ser HOME is set?
\ctxlua{print("1",environment.homedir)}
\ctxlua{print("2",environment.oldhome)}
\ctxlua{print("3",os.getenv("HOME"))}
