Dear list,
I have the following sample:
\showframe\showgrid
\setuplayout[width=middle]
\definefontfamily[mainface][rm][TeX Gyre Pagella]
[features={default, quality}]
\setupbodyfont[mainface, 20pt]
\setupalign[hanging, hz]
\starttext
\dorecurse{25}{\input{zapf}\input{cuomo}}
\stoptext
On page 36 (https://pdf.ousia.tk/wrong-font-expansion.pdf#page=36),
lines 4, 11 and 20 are wrong.
Current LMTX (LuaTeX 2.07 20200920 + ConTeXt MkIV 2020.09.20 23:02) has
the issue, while MkIV (LuaTeX 1.11 7226 + ConTeXt MkIV 2020.01.30 14:13)
has no problem with that.
I think this might be a bug. Could you confirm the issue?
I need to keep count of how frequently i suggest typo also
\setupalign[verytolerant,stretch]
when one uses hz and/or protrusion. I don't know why folks expect
expansion and protrusion to give better (or intended) output when the
other constraints are such that tex either not even ends up in the phase
where expansion is applied, or when fitting the constraints is only
possible with excessive and visible expansion. When expansion is max or
min and there is not enough spacing to stretch and shrink the results
will not get better. Read: expansion is a last resort in getting things
right. Also, protrusion actually add to the constraints so that is never
a way to get a better fit.
Anyway, with tolerant and stretch the test looks ok here.
