Some useful (English language) macros for testing

[simoncozens]

These days I just do:

\begin[papersize=a3,class=fontproof]{document}
\setTestFont[filename=Coolangatta-SemiBold.otf,size=25pt]

\proof:arrowroot

\proof:bringhurst

\proof:allkernpairs\proof:jafkerns

\end{document}

[n7s]

getting this error with current sile master and both @jvgaultney's examples and the one above:

/usr/local/share/sile/packages/bidi.lua:155: Bidi run too big? U_BUFFER_OVERFLOW_ERROR

[simoncozens]

Right you are, I need to also turn \bidi-off. This is because the jafkerns paragraph is extremely long. Ideally we should make that buffer dynamically assigned.

[simoncozens]

OK, SILE now dynamically assigns that buffer...

works for me, thanks
