You should not be writing tables in abstracts!
Here is my attempt. Seems to work correctly for simple text,
references, simple markup etc. Try anything too fancy and you are in
trouble. I changed the name to start stop stats, as I was mistyping
startstatistics :-).
\starttext
\bgroup
\catcode`~=\active
\catcode`-=\active
\gdef\ignorestats%
{% treat non-breakable space as a normal one
\catcode`~=\active
\let~=\space
% treat endash, emdash and - as normal space
\catcode`-=\active
\def-{ }
%\setupframed[align=normal]%Frames do not work correctly
}
\gdef\startdostats%
{\bgroup
\setbox0\vbox\bgroup % \tracingall -)
\forgetall \nohyphens \hsize1mm}
\gdef\stopdostats%
{\egroup
\newcounter\NOfLines
\dontcomplain %Why do I still get overfull \hbox warnings
\beginshapebox \unvcopy0 \endshapebox
\reshapebox{\doglobal\increment\NOfLines}
\getnoflines{\ht0}
\unvbox0 %Uncomment for debug
\par lines: \the\noflines\space
words: \NOfLines\par\egroup}
\long\gdef\startstats#1\stopstats%
{\bgroup\ignorestats
\startdostats\scantokens{#1}\stopdostats\egroup}
\egroup
\def\ShowStats#1{\hairline#1\par\startstats#1\stopstats}
\ShowStats{abc~def ghi-jkl -- mno --- prs}
\ShowStats{abc-def -- ghi --- jkl}
\ShowStats{a, b}
\section[a]{one}
\ShowStats{We do some great things in \in{section}[a]}
% I do not know the internals, but section 1 seems unbreakable
\ShowStats{$a=b$} %What did you expect? It may be possible to treat
%each math token as mathord and allow it to break
%but that will not give any better results.
\startbuffer
This is a test
\stopbuffer
\ShowStats{\getbuffer}
\ShowStats{\startformula a = b + c \stopformula}
\ShowStats{\framed{This is a test}}
\ShowStats{\starthiding Another test \stophiding Does this work?}
% Buffers do not work and fail silently.
\ShowStats{This is {\bf Bold} and {\it Italic}}
\ShowStats{\input tufte}
\stoptext
