Hi,
I just did an upload. Apart from a few catches (like that arrow and some
improvements in columnsets) the main additions are in the metafun
department and performance.
- We added some parpasses (like 'mathbook') and we can now set them up
with the align options. The vectors used are defined as constants
(engine speak) which makes the performance impact kind of neglectable.
- Also some predefined penalty vectors (think widowpenalties) became
constant (as it's unlikely or unwise to change them) which is more
efficient as they otherwise get copied every paragraph.
- When testing with Mikaels math book (290 pages in 7.4 sec on his
chromebook) we'd set a new target at 7 and later 6 seconds and
eventually could get that and ended up at 5.3 seconds once we noticed
that there was an huge graphic involved (so now our target is 4 sec).
Caching demanding mp graphics helped but was still good for > .5
seconds. As a consequence we added a new function variant (see
luametafun, domain functions so that runtime went down from > .5 seconds
to about .03 sec) and we also made sure that inclusion of cached mp
pages was more performant (when 'compact' inclusion is enabled in the
page streams get parsed).
- When multiple lua driven rendering features are used (happens seldom)
there can be a bit of a speedup too. If someone thinks that there is a
botleneck somewhere .. make an example and tell us.
(Of course bying a new fancy laptop would half my runtime anyway but
occasionally one wants a challenge.)
- There is now a ppchtex-mkiv manual but it's work in progress and it
needs checking. One thing I observed is that as we now default to
'double' instead of 'scaled' some rounding / comparison cases differ so
when in douuibt, check with:
% \ctxlua{chemistry.method = "scaled"}
We still need to check / add updated columnset manuals so that might be
next on the agenda.
That's all,
Hans
