Hi,
I have just uploaded the archives for a new luatex release, 0.78.0.
This release merges some experimental branches, and fixes a few of the
outstanding bugs.
Thanks Taco and the team!
* Instead of using expanded fonts, just calculate the expanded
width of glyphs where needed, and carry expand info in the
glyph nodes (all based on Hans' suggestions). All font expansion
functions are disabled and most are removed.
Nice: now glyphs in expanded lines still have their original “font”
field.
If I’m not mistaken, the width of and expanded glyph (or kern) is:
n.width + n.width * n.expansion_factor/1,000,000
Is that correct?
[Note that “expansion_factor” is mentionned but not documented for
kerns.]
because expanded kerns might disappear (makes no sense to expand kerns)
or become optional
* New, faster (but limited) direct node access from lua, see
the manual for details
From what I can understand from the manual, “node.getnext(n)” is
faster than “node.next(n)” which is faster than “n.next”; but faster
still is “node.direct.getnext(node.direct.todirect(n))”; is that
correct?
[The “todirect” function is said to exist in both “node” and
“node.direct”, but it is only in the latter.]
yes, but only faster in extreme cases (it's also a trade of between
readability n.next and speed node.direct.getnext(n))
