Hi,
say I have arbitrary string of alphanumeric characters:
\starttext
\showframe
9769387937933hhgiuiuziuziduzid93739837fhieuhifeuhfeiu39739837938398zfhfdkuhfiufhz398739837r98z379dihhfiu
\stoptext
How can I (automatically) force a break at end of line, without manually adding \crlf or \break at break points?
\handletokens ...\with{\hskip 0pt plus .1pt\firstofoneargument}
Yes, this helps:
\showframe
\define[1]\ThisHelps {\handletokens#1\with{\hskip 0pt plus .1pt\firstofoneargument}}
Test text test text\ThisHelps {9769387937933hhgiuiuziuziduzid93739837fhieuhifeuhfeiu39739837938398zfhfdkuhfiufhz398739837r98z379dihhfiu}
\stoptext
Thank you!!

Where is the difference ?
\starttext
\showframe
\define[1]\ThisHelps {\handletokens#1\with{\hskip 0pt plus
.1pt\firstofoneargument}}
Test text test text\ThisHelps
{9769387937933hhgiuiuziuziduzid93739837fhieuhifeuhfeiu39739837938398zfhfdkuhfiufhz398739837r98z379dihhfiu}
\define[1]\ThisHelpsLuigi{%
\startluacode
s='#1'
s= string.gsub(s,'(.)',"\%1\\hskip0sp")
% maybe only some chars...
%s= string.gsub(s,'[=/]',"\%1\\hskip0sp")
context(s)
\stopluacode}

Just my "greenness" with luacode ...

I didn't expect that it could be wrapped so easily in an handy \define command:
context(s) is wrapped in start/stopluacode is wrapped in \define[1]\LuigiHelps{...}

Endless possibilities ... great!

Thank you very much for making this clear :o)
