Hi,

I uploaded a new version. Apart from a few fixes / extensions already mentioned here (or known to those who wanted it) the main changes are in the math goodie files (work in progress, we will clean them up later) as part of improving the rendering of math.

Something is wrong with the placement of limits around an integral with

NeoEuler:

\usetypescriptfile[euler]

\definetypeface[mainfont][rm][specserif][CharisSil][default] \definetypeface[mainfont][mm][math] [eulernova][default] \definetypeface[mainfont][tt][mono] [dejavu][default] [rscale=0.8,

features=none]

\setupbodyfont[mainfont,10pt]

\starttext \startTEXpage[offset=1mm] $\displaystyle \int_{0}^{1} f(x) dx$ \stopTEXpage \stoptext

gives the attached result.

This is because the integral "sits wrong" in its boundingbox. Almost all fonts have the glyph centered around the math axis, but there are a few that doesn't. In euler-math.lfg, add the tweak

{ tweak = "fixoldschool", },

This fixes the issue with eulernova, but not with pagellaovereuler.

With tweak=fixoldschool, \startcases doesn't work correctly (see attached):

\usetypescriptfile[euler]

\definetypeface[mainfont][rm][specserif][CharisSil][default] \definetypeface[mainfont][mm][math] [eulernova][default] \definetypeface[mainfont][tt][mono] [dejavu][default] [rscale=0.8,

features=none]

\setupbodyfont[mainfont,10pt]

\starttext \startTEXpage[offset=1mm] \startformula \startcases \NC A \NC B \NR \NC C \NC D \NR \stopcases \stopformula \stopTEXpage \stoptext

Looks like some older experimental value is wrong:

parameters = { -- DelimiterPercent = 901, DelimiterShortfall = 500, },

(that whole lfg is a todo)

Thanks. This fixes the delimiters. Aditya
