Is there a way to link to a page or a destination (such as in

to a document that is attached (using \attachment) in ConTeXt?

I hope it is clear now,
it points to the media mess .. which relates to either or not obsolete 
stuff (flash related)


anyway, i don't know as i never embed pdf docs and if i would i'd have 
no reason to refer to them (it probably depends on a viewer extracting 
the attachment, caching it and then providing access: it makes no sense 
to waste time on features that are not supported or maybe only by 
acrobat unless it's a well paid projects in which case throw away code 
is a bit less waste of time because it brings foon on the table)

I didn't quite follow the discussion and the suggested code, but
from a similar discussion for latex I know that the symbols in
fontawesome 4 and 5 looks different (that's why there is an explicit
fontawesome5 package in latex).


Then Wolfgang's solution makes even more sense as it is possible to use 
BOTH v4 and v5 of the font.

Is there a way to link to a page or a destination (such as in
https://www.adobe.com/content/dam/acom/en/devnet/pdf/PDF32000_2008.pdf#page=500
or

I hope it is clear now,

Thanks both to luigi and to Alan! I'm impressed by your brute force
method, Alan! In particular it learned me the "hide" command.

I feel a bit ashamed. Earlier today I answered something else giving a
reference to the metafun manual. Now I'm here not reading it carefully
enough myself. In the helpers section it is clearly written how to
import and plot data. Thus, I exported the data from the Mathematica
plot (that file is pasted below in case anyone wants to try this
themselves, sorry in advance for the big amount of text it generates
in this email) and then importing it just worked fine. I like Alan's
method very much, but it takes some time during compilation, so I will
probably stick with importing. Working code below (where one can see
that Alan's method is indeed working fine, at least with this
example).

Again, thanks to both luigi and Alan!

I'm not aware of any such effort so far, but we gladly help you if you

Obtaining the latest version is already relatively easy, but I fully
understand your point :)

Maybe
https://github.com/contextgarden/context-mirror
comes closest to what you are looking for, but note that ConTeXt
provides several releases per day (or maybe a release every few days
at most) which is more resembling individual commits in other projects
than one release per every few months as would be common with other
projects.

The only thing that comes somewhat closer to a release is a version
that gets released with TeX Live once per year, but that's not in line
with your desire to easily get the latest version. We had the latest
version of ConTeXt in TLContrib repository for a while which could
probably be reinstated if desired, but that means using MacTeX (even
if from HB).

If you want to provide a package for HB, you either need to use "HEAD"
or create a cron job that will update the package definition several
times per day :) :) :)

But note that installing ConTeXt alone is not sufficient. You also
need LuaTeX, a bunch of fonts and other files (I'm not sure which
ones; with the old ConTeXt MKII it was a lot more dependencies than
with the new ConTeXt MKIV). The easiest way would be to install TeX
Live as a dependency, but from what I saw I suspect that HB only
packages MacTeX as a binary installation. You could install ConTeXt on
top of that in a way that doesn't conflict. Alternatively you need to
spend (quite some) effort figuring out what exactly is needed.

I'll probably create another git repository with a standalone
installation, but it's not yet ready and you should not count on it.

I suspect that you'll find a slightly hard time getting this package
into core HomeBrew and that you'll need to provide your own
repository, but I might be wrong. I decided against providing a
package for MacPorts precisely because it's not really practical to
update a package definition every few days.

I didn't quite follow the discussion and the suggested code, but
from a similar discussion for latex I know that the symbols in
fontawesome 4 and 5 looks different (that's why there is an explicit
fontawesome5 package in latex).

you need some  " Groebner basis computation " kernel to do this kind of

[NTG-context] Implicit plots/level curves possible?

[Mikael P. Sundqvist]

Dear list,

Is it possiblet to make implicit plots (i.e. ploting the curves
described by equations) in MetaFun? I cannot find anything about them
in the MetaFun manual.

For example, in Mathematica I can write something like

ContourPlot[2 x^5 + x y + y^5 == 0, {x, 0, 2}, {y, -2, 1/2}]

to get the attached figure.

The closest I have found which is something MetaPost-like, is the
levelcurve command in mfpic (see for example this answer
https://tex.stackexchange.com/a/405527/52406).

If this is not currently possible in MetaFun, what is the simplest way
to proceed (I want the same style of the plots as the other ones in my
doc)? Is it to

1) somehow run mfpic from within ConTeXt?
2) export points from Mathematica and plot them in ConTeXt (how could
that be done?). In the latter case, say I have the points (0,0),
(0.4,1), and (0.8,2) exported to a file. What format should it be in
to be easily imported and plot in MetaFun?
3) some other way?

I don't recall the problem, maybe using LuaTeX in another context that ConTeXt, 
so having to keep track of that switch.

hm,  sqlite uses luaffi, not swiglib.

Put libsqlite3.so  in the same folder of your example, and rename it
as sqlite3.so

Then put in your example
\setuppapersize[A4]
\enabletrackers[resolvers.ffilib]
\enabletrackers[sql.trace]
\enabletrackers[sql.queries]

I think that at least you should see something like
found: '//sqlite3.so'

Re: [NTG-context] filling overlap ?

[Floris van Manen]

so digging a little deeper brings me this solution:

path p ; p := fullsquare xscaled 10mm yscaled 12mm superellipsed .7 ;
path q ; q := fullsquare xscaled  9mm yscaled 11mm superellipsed .7 ;
q := q shifted (3mm, -2mm);
path r ; r := fullsquare xscaled  8mm yscaled 10mm superellipsed .7 ;
r := r shifted (0mm, -4mm);

fill p withcolor red ;
clip currentpicture to q ;
clip currentpicture to r ;

draw p ;
draw q ;
draw r ;

Hi!

This is something similar as in page 304 of the manual
http://www.pragma-ade.com/general/manuals/metafun-p.pdf

\startMPpage
path p ; p := fullsquare xscaled 10mm yscaled 12mm superellipsed .7 ;
path q ; q := fullsquare xscaled  9mm yscaled 11mm superellipsed .7 ;
q := q shifted (3mm, -2mm);
path r ; r := fullsquare xscaled  8mm yscaled 10mm superellipsed .7 ;
r := r shifted (0mm, -4mm);
path pr,pqr;
pr = buildcycle(p, r);
%fill pr withcolor 0.5white;
pqr = buildcycle(q,pr) ;
fill pqr withcolor darkyellow;
draw p ;
draw q withcolor darkred;
draw r withcolor darkblue;

[NTG-context] filling overlap ?

[Floris van Manen]

Could someone point me to te way as how to fill only the overlap of three paths 
using metafun ?

path p ; p := fullsquare xscaled 10mm yscaled 12mm superellipsed .7 ;
path q ; q := fullsquare xscaled  9mm yscaled 11mm superellipsed .7 ;
q := q shifted (3mm, -2mm);
path r ; r := fullsquare xscaled  8mm yscaled 10mm superellipsed .7 ;
r := r shifted (0mm, -4mm);
draw p ;
draw q ;
draw r ;

This project

I think we could have something like this on the frontpage of the wiki
for quick installation.

A script that does all this:

mkdir ~/context
cd ~/context
wget http://minimals.contextgarden.net/setup/first-setup.sh
sh ./first-setup.sh --modules=all


So people could install the latest beta with something like this:

curl http://minimals.contextgarden.net/setup/first-setup.sh | bash
but after that updating is just calling first-setup again, no need to 
reinstall

How do you now update? It's just one recall to first-setup.sh


It would be better to put the development version in TeXLive as a separate package—on 
MacOS, it comes with the TeX Live Utility which gives update notifications 
frequently, once a week, but one can run it more frequently by hand. Just give it a 
different name than from the ordinary distribution, say context-.

When I used the beta, it was difficult to switch with other TeX software. So 
this might be better.
hm, you can install context alongside texlive and just change the path 
as everything else is picked up from that (also a lightweight context 
distribution is normally faster than context in texlive)


(till now we only update context in telive once per year and i don't 
know if mojca pushes the latest context in there for the updating; till 
now often it went in sync with a luatex update)
