Hi,
did anyone succeed in externalizing TikZ graphics with ConTeXt?
It’s about a project with hundreds of diagrams that (in the current state)

component name) and that on each ConTeXt run take a lot of runtime (I guess
also the many log lines slow the process).
In 2013, Aditya said it wasn’t possible to externalize pgf/TikZ graphics as documented in
the pgf manual, and "perhaps" it would make sense to use his filter module:
https://mailman.ntg.nl/pipermail/ntg-context/2013/071162.html
Did anyone try to do that? I didn’t find anything in this list’s archives.
The original pgf way is two-pass, and you’d need to call LaTeX with the
intended graphics name as --jobname; that’s far too much of a hassle for that
many graphics.
I generally like how the filter module works, as you can also define the name
of every buffer, but my only experience with that is my LilyPond setup.
If nobody has better advice, I’ll try to come up with a filter setup. That
would mean we’d avoid the tikz module, every TikZ diagram will get written to a
buffer of configurable name, and that (with preamble setup) will get run
through LaTeX. I read pgf had some restrictions in plain TeX mode, but perhaps
we can also use LuaTeX in plain mode to avoid the LaTeX dependency.
In the following case the buffer only gets typeset when it changes:
\starttext
\startbuffer[foo]
% maybe include a style / enviroment
\usemodule[tikz] \usetikzlibrary[patterns]
\startTEXpage
\starttikzpicture
\draw[pattern color=red,pattern=bricks] (0,0) circle (1cm);
\stoptikzpicture
\stopTEXpage
\stopbuffer
\framed[offset=overlay]{\typesetbuffer[foo]}

It is not only the tikz setup; you also need to copy the font setup etc.
\typesetbuffer[setups,figure]
or some variant of that should also work. But the filter module does make it
easier to store the results in another directory so that they are out of sight.

Compare the output between the current LMTX version with some old version. (I
compared with mk4, because I had nothing else available. I don't know when bugs
were introduced.)
I'll check it. We're in a transition to a dual font model in math and
it's kind of tricky to let both do the same but we'll get there
eventually. It also has some consequences for backand code which makes
it even more tricky. But normally, once it does work it keeps working.

Maybe something wrong with lazy loading? The remote cat was missing from ConTeXt’s image cache. I fixed that now by editing the source (added a space), which made the wiki rerun ConTeXt, and that in turn made ConTeXt re-fetch the url contents. The other images all load fine for me. Images for ‘’ blocks can be a little tricky, because the wiki software caches them based on a hash of the block’s contents. So if something transient goes wrong in the ConTeXt processing but ConTeXt still outputs some sort of PDF, then that output will never get fixed unless you edit the wiki source again. That does not happen a lot, but it is likelier to happen with remote content. There are two ways around this: 1. edit the block source slightly, by adding a space or a % or something else that is harmless. That changes the hash key of the content, and the wiki will (probably) regenerate the graphic. 2. There is a ‘secret’ force attribute for , but that should only be used to apply fixes like the one I did above, and it should be removed afterwards. That attribute bypasses the wiki caching altogether. But as that is really bad for the webserver’s performance, it should only be used if there is no other way.

[NTG-context] Inline Fractions
Recently inline fractions stopped working correctly.
For example symbol spacing, sub-/superscripts, the line is too short,...
You can see the 3 named problems and how they sometimes appear and sometimes not
in this two fractions:
\starttext
$\frac{\sin(x)}{16 \pi \epsilon_0 c^2 m_e^2} \frac{\sin(x)}{\epsilon_0}$
\stoptext
Compare the output between the current LMTX version with some old version. (I
compared with mk4, because I had nothing else available. I don't know when bugs
were introduced.)
Best regards,
Johann
